- -------------------------------------------------------
-
-#261. (Changed in MR19) Defer token fetch for C++ mode
-
- Item #216 has been revised to indicate that use of the defer fetch
- option (ZZDEFER_FETCH) requires dlg option -i.
-
-#260. (MR22) Raise default lex buffer size from 8,000 to 32,000 bytes.
-
- ZZLEXBUFSIZE is the size (in bytes) of the buffer used by dlg
- generated lexers. The default value has been raised to 32,000 and
- the value used by antlr, dlg, and sorcerer has also been raised to
- 32,000.
-
-#259. (MR22) Default function arguments in C++ mode.
-
- If a rule is declared:
-
- rr [int i = 0] : ....
-
- then the declaration generated by pccts resembles:
-
- void rr(int i = 0);
-
- however, the definition must omit the default argument:
-
- void rr(int i) {...}
-
- In the past the default value was not omitted. In MR22
- the generated code resembles:
-
- void rr(int i /* = 0 */ ) {...}
-
- Implemented by Volker H. Simonis (simonis@informatik.uni-tuebingen.de)
-
-#258. (MR22) Using a base class for your parser
-
- In item #102 (MR10) the class statement was extended to allow one
- to specify a base class other than ANTLRParser for the generated
- parser. It turned out that this was less than useful because
- the constructor still specified ANTLRParser as the base class.
-
- The class statement now uses the first identifier appearing after
- the ":" as the name of the base class. For example:
-
- class MyParser : public FooParser {
-
- Generates in MyParser.h:
-
- class MyParser : public FooParser {
-
- Generates in MyParser.cpp something that resembles:
-
- MyParser::MyParser(ANTLRTokenBuffer *input) :
- FooParser(input,1,0,0,4)
- {
- token_tbl = _token_tbl;
- traceOptionValueDefault=1; // MR10 turn trace ON
- }
-
- The base class must constructor must have a signature similar to
- that of ANTLRParser.
-
-#257. (MR21a) Removed dlg statement that -i has no effect in C++ mode.
-
- This was incorrect.
-
-#256. (MR21a) Malformed syntax graph causes crash after error message.
-
- In the past, certain kinds of errors in the very first grammar
- element could cause the construction of a malformed graph
- representing the grammar. This would eventually result in a
- fatal internal error. The code has been changed to be more
- resistant to this particular error.
-
-#255. (MR21a) ParserBlackBox(FILE* f)
-
- This constructor set openByBlackBox to the wrong value.
-
- Reported by Kees Bakker (kees_bakker@tasking.nl).
-
-#254. (MR21a) Reporting syntax error at end-of-file
-
- When there was a syntax error at the end-of-file the syntax
- error routine would substitute "<eof>" for the programmer's
- end-of-file symbol. This substitution is now done only when
- the programmer does not define his own end-of-file symbol
- or the symbol begins with the character "@".
-
- Reported by Kees Bakker (kees_bakker@tasking.nl).
-
-#253. (MR21) Generation of block preamble (-preamble and -preamble_first)
-
- The antlr option -preamble causes antlr to insert the code
- BLOCK_PREAMBLE at the start of each rule and block. It does
- not insert code before rules references, token references, or
- actions. By properly defining the macro BLOCK_PREAMBLE the
- user can generate code which is specific to the start of blocks.
-
- The antlr option -preamble_first is similar, but inserts the
- code BLOCK_PREAMBLE_FIRST(PreambleFirst_123) where the symbol
- PreambleFirst_123 is equivalent to the first set defined by
- the #FirstSetSymbol described in Item #248.
-
- I have not investigated how these options interact with guess
- mode (syntactic predicates).
-
-#252. (MR21) Check for null pointer in trace routine
-
- When some trace options are used when the parser is generated
- without the trace enabled, the current rule name may be a
- NULL pointer. A guard was added to check for this in
- restoreState.
-
- Reported by Douglas E. Forester (dougf@projtech.com).
-
-#251. (MR21) Changes to #define zzTRACE_RULES
-
- The macro zzTRACE_RULES was being use to pass information to
- AParser.h. If this preprocessor symbol was not properly
- set the first time AParser.h was #included, the declaration
- of zzTRACEdata would be omitted (it is used by the -gd option).
- Subsequent #includes of AParser.h would be skipped because of
- the #ifdef guard, so the declaration of zzTracePrevRuleName would
- never be made. The result was that proper compilation was very
- order dependent.
-
- The declaration of zzTRACEdata was made unconditional and the
- problem of removing unused declarations will be left to optimizers.
-
- Diagnosed by Douglas E. Forester (dougf@projtech.com).
-
-#250. (MR21) Option for EXPERIMENTAL change to error sets for blocks
-
- The antlr option -mrblkerr turns on an experimental feature
- which is supposed to provide more accurate syntax error messages
- for k=1, ck=1 grammars. When used with k>1 or ck>1 grammars the
- behavior should be no worse than the current behavior.
-
- There is no problem with the matching of elements or the computation
- of prediction expressions in pccts. The task is only one of listing
- the most appropriate tokens in the error message. The error sets used
- in pccts error messages are approximations of the exact error set when
- optional elements in (...)* or (...)+ are involved. While entirely
- correct, the error messages are sometimes not 100% accurate.
-
- There is also a minor philosophical issue. For example, suppose the
- grammar expects the token to be an optional A followed by Z, and it
- is X. X, of course, is neither A nor Z, so an error message is appropriate.
- Is it appropriate to say "Expected Z" ? It is correct, it is accurate,
- but it is not complete.
-
- When k>1 or ck>1 the problem of providing the exactly correct
- list of tokens for the syntax error messages ends up becoming
- equivalent to evaluating the prediction expression for the
- alternatives twice. However, for k=1 ck=1 grammars the prediction
- expression can be computed easily and evaluated cheaply, so I
- decided to try implementing it to satisfy a particular application.
- This application uses the error set in an interactive command language
- to provide prompts which list the alternatives available at that
- point in the parser. The user can then enter additional tokens to
- complete the command line. To do this required more accurate error
- sets then previously provided by pccts.
-
- In some cases the default pccts behavior may lead to more robust error
- recovery or clearer error messages then having the exact set of tokens.
- This is because (a) features like -ge allow the use of symbolic names for
- certain sets of tokens, so having extra tokens may simply obscure things
- and (b) the error set is use to resynchronize the parser, so a good
- choice is sometimes more important than having the exact set.
-
- Consider the following example:
-
- Note: All examples code has been abbreviated
- to the absolute minimum in order to make the
- examples concise.
-
- star1 : (A)* Z;
-
- The generated code resembles:
-
- old new (with -mrblkerr)
- ------------- --------------------
- for (;;) { for (;;) {
- match(A); match(A);
- } }
- match(Z); if (! A and ! Z) then
- FAIL(...{A,Z}...);
- }
- match(Z);
-
-
- With input X
- old message: Found X, expected Z
- new message: Found X, expected A, Z
-
- For the example:
-
- star2 : (A|B)* Z;
-
- old new (with -mrblkerr)
- ------------- --------------------
- for (;;) { for (;;) {
- if (!A and !B) break; if (!A and !B) break;
- if (...) { if (...) {
- <same ...> <same ...>
- } }
- else { else {
- FAIL(...{A,B,Z}...) FAIL(...{A,B}...);
- } }
- } }
- match(B); if (! A and ! B and !Z) then
- FAIL(...{A,B,Z}...);
- }
- match(B);
-
- With input X
- old message: Found X, expected Z
- new message: Found X, expected A, B, Z
- With input A X
- old message: Found X, expected Z
- new message: Found X, expected A, B, Z
-
- This includes the choice of looping back to the
- star block.
-
- The code for plus blocks:
-
- plus1 : (A)+ Z;
-
- The generated code resembles:
-
- old new (with -mrblkerr)
- ------------- --------------------
- do { do {
- match(A); match(A);
- } while (A) } while (A)
- match(Z); if (! A and ! Z) then
- FAIL(...{A,Z}...);
- }
- match(Z);
-
- With input A X
- old message: Found X, expected Z
- new message: Found X, expected A, Z
-
- This includes the choice of looping back to the
- plus block.
-
- For the example:
-
- plus2 : (A|B)+ Z;
-
- old new (with -mrblkerr)
- ------------- --------------------
- do { do {
- if (A) { <same>
- match(A); <same>
- } else if (B) { <same>
- match(B); <same>
- } else { <same>
- if (cnt > 1) break; <same>
- FAIL(...{A,B,Z}...) FAIL(...{A,B}...);
- } }
- cnt++; <same>
- } }
-
- match(Z); if (! A and ! B and !Z) then
- FAIL(...{A,B,Z}...);
- }
- match(B);
-
- With input X
- old message: Found X, expected A, B, Z
- new message: Found X, expected A, B
- With input A X
- old message: Found X, expected Z
- new message: Found X, expected A, B, Z
-
- This includes the choice of looping back to the
- star block.
-
-#249. (MR21) Changes for DEC/VMS systems
-
- Jean-François Piéronne (jfp@altavista.net) has updated some
- VMS related command files and fixed some minor problems related
- to building pccts under the DEC/VMS operating system. For DEC/VMS
- users the most important differences are:
-
- a. Revised makefile.vms
- b. Revised genMMS for genrating VMS style makefiles.
-
-#248. (MR21) Generate symbol for first set of an alternative
-
- pccts can generate a symbol which represents the tokens which may
- appear at the start of a block:
-
- rr : #FirstSetSymbol(rr_FirstSet) ( Foo | Bar ) ;
-
- This will generate the symbol rr_FirstSet of type SetWordType with
- elements Foo and Bar set. The bits can be tested using code similar
- to the following:
-
- if (set_el(Foo, &rr_FirstSet)) { ...
-
- This can be combined with the C array zztokens[] or the C++ routine
- tokenName() to get the print name of the token in the first set.
-
- The size of the set is given by the newly added enum SET_SIZE, a
- protected member of the generated parser's class. The number of
- elements in the generated set will not be exactly equal to the
- value of SET_SIZE because of synthetic tokens created by #tokclass,
- #errclass, the -ge option, and meta-tokens such as epsilon, and
- end-of-file.
-
- The #FirstSetSymbol must appear immediately before a block
- such as (...)+, (...)*, and {...}, and (...). It may not appear
- immediately before a token, a rule reference, or action. However
- a token or rule reference can be enclosed in a (...) in order to
- make the use of #pragma FirstSetSymbol legal.
-
- rr_bad : #FirstSetSymbol(rr_bad_FirstSet) Foo; // Illegal
-
- rr_ok : #FirstSetSymbol(rr_ok_FirstSet) (Foo); // Legal
-
- Do not confuse FirstSetSymbol sets with the sets used for testing
- lookahead. The sets used for FirstSetSymbol have one element per bit,
- so the number of bytes is approximately the largest token number
- divided by 8. The sets used for testing lookahead store 8 lookahead
- sets per byte, so the length of the array is approximately the largest
- token number.
-
- If there is demand, a similar routine for follow sets can be added.
-
-#247. (MR21) Misleading error message on syntax error for optional elements.
-
- Prior to MR21, tokens which were optional did not appear in syntax
- error messages if the block which immediately followed detected a
- syntax error.
-
- Consider the following grammar which accepts Number, Word, and Other:
-
- rr : {Number} Word;
-
- For this rule the code resembles:
-
- if (LA(1) == Number) {
- match(Number);
- consume();
- }
- match(Word);
-
- Prior to MR21, the error message for input "$ a" would be:
-
- line 1: syntax error at "$" missing Word
-
- With MR21 the message will be:
-
- line 1: syntax error at "$" expecting Word, Number.
-
- The generate code resembles:
-
- if ( (LA(1)==Number) ) {
- zzmatch(Number);
- consume();
- }
- else {
- if ( (LA(1)==Word) ) {
- /* nothing */
- }
- else {
- FAIL(... message for both Number and Word ...);
- }
- }
- match(Word);
-
- The code generated for optional blocks in MR21 is slightly longer
- than the previous versions, but it should give better error messages.
-
- The code generated for:
-
- { a | b | c }
-
- should now be *identical* to:
-
- ( a | b | c | )
-
- which was not the case prior to MR21.
-
- Reported by Sue Marvin (sue@siara.com).
-
-#246. (Changed in MR21) Use of $(MAKE) for calls to make
-
- Calls to make from the makefiles were replaced with $(MAKE)
- because of problems when using gmake.
-
- Reported with fix by Sunil K.Vallamkonda (sunil@siara.com).
-
-#245. (Changed in MR21) Changes to genmk
-
- The following command line options have been added to genmk:
-
- -cfiles ...
-
- To add a user's C or C++ files into makefile automatically.
- The list of files must be enclosed in apostrophes. This
- option may be specified multiple times.
-
- -compiler ...
-
- The name of the compiler to use for $(CCC) or $(CC). The
- default in C++ mode is "CC". The default in C mode is "cc".
-
- -pccts_path ...
-
- The value for $(PCCTS), the pccts directory. The default
- is /usr/local/pccts.
-
- Contributed by Tomasz Babczynski (t.babczynski@ict.pwr.wroc.pl).
-
-#244. (Changed in MR21) Rename variable "not" in antlr.g
-
- When antlr.g is compiled with a C++ compiler, a variable named
- "not" causes problems. Reported by Sinan Karasu
- (sinan.karasu@boeing.com).
-
-#243 (Changed in MR21) Replace recursion with iteration in zzfree_ast
-
- Another refinement to zzfree_ast in ast.c to limit recursion.
-
- NAKAJIMA Mutsuki (muc@isr.co.jp).
-
-
-#242. (Changed in MR21) LineInfoFormatStr
-
- Added an #ifndef/#endif around LineInfoFormatStr in pcctscfg.h.
-
-#241. (Changed in MR21) Changed macro PURIFY to a no-op
-
- ***********************
- *** NOT IMPLEMENTED ***
- ***********************
-
- The PURIFY macro was changed to a no-op because it was causing
- problems when passing C++ objects.
-
- The old definition:
-
- #define PURIFY(r,s) memset((char *) &(r),'\\0',(s));
-
- The new definition:
-
- #define PURIFY(r,s) /* nothing */
-#endif
-
-#240. (Changed in MR21) sorcerer/h/sorcerer.h _MATCH and _MATCHRANGE
-
- Added test for NULL token pointer.
-
- Suggested by Peter Keller (keller@ebi.ac.uk)
-
-#239. (Changed in MR21) C++ mode AParser::traceGuessFail
-
- If tracing is turned on when the code has been generated
- without trace code, a failed guess generates a trace report
- even though there are no other trace reports. This
- make the behavior consistent with other parts of the
- trace system.
-
- Reported by David Wigg (wiggjd@sbu.ac.uk).
-
-#238. (Changed in MR21) Namespace version #include files
-
- Changed reference from CStdio to cstdio (and other
- #include file names) in the namespace version of pccts.
- Should have known better.
-
-#237. (Changed in MR21) ParserBlackBox(FILE*)
-
- In the past, ParserBlackBox would close the FILE in the dtor
- even though it was not opened by ParserBlackBox. The problem
- is that there were two constructors, one which accepted a file
- name and did an fopen, the other which accepted a FILE and did
- not do an fopen. There is now an extra member variable which
- remembers whether ParserBlackBox did the open or not.
-
- Suggested by Mike Percy (mpercy@scires.com).
-
-#236. (Changed in MR21) tmake now reports down pointer problem
-
- When ASTBase::tmake attempts to update the down pointer of
- an AST it checks to see if the down pointer is NULL. If it
- is not NULL it does not do the update and returns NULL.
- An attempt to update the down pointer is almost always a
- result of a user error. This can lead to difficult to find
- problems during tree construction.
-
- With this change, the routine calls a virtual function
- reportOverwriteOfDownPointer() which calls panic to
- report the problem. Users who want the old behavior can
- redefined the virtual function in their AST class.
-
- Suggested by Sinan Karasu (sinan.karasu@boeing.com)
-
-#235. (Changed in MR21) Made ANTLRParser::resynch() virtual
-
- Suggested by Jerry Evans (jerry@swsl.co.uk).
-
-#234. (Changed in MR21) Implicit int for function return value
-
- ATokenBuffer:bufferSize() did not specify a type for the
- return value.
-
- Reported by Hai Vo-Ba (hai@fc.hp.com).
-
-#233. (Changed in MR20) Converted to MSVC 6.0
-
- Due to external circumstances I have had to convert to MSVC 6.0
- The MSVC 5.0 project files (.dsw and .dsp) have been retained as
- xxx50.dsp and xxx50.dsw. The MSVC 6.0 files are named xxx60.dsp
- and xxx60.dsw (where xxx is the related to the directory/project).
-
-#232. (Changed in MR20) Make setwd bit vectors protected in parser.h
-
- The access for the setwd array in the parser header was not
- specified. As a result, it would depend on the code which
- preceded it. In MR20 it will always have access "protected".
-
- Reported by Piotr Eljasiak (eljasiak@zt.gdansk.tpsa.pl).
-
-#231. (Changed in MR20) Error in token buffer debug code.
-
- When token buffer debugging is selected via the pre-processor
- symbol DEBUG_TOKENBUFFER there is an erroneous check in
- AParser.cpp:
-
- #ifdef DEBUG_TOKENBUFFER
- if (i >= inputTokens->bufferSize() ||
- inputTokens->minTokens() < LLk ) /* MR20 Was "<=" */
- ...
- #endif
-
- Reported by David Wigg (wiggjd@sbu.ac.uk).
-
-#230. (Changed in MR20) Fixed problem with #define for -gd option
-
- There was an error in setting zzTRACE_RULES for the -gd (trace) option.
-
- Reported by Gary Funck (gary@intrepid.com).
-
-#229. (Changed in MR20) Additional "const" for literals
-
- "const" was added to the token name literal table.
- "const" was added to some panic() and similar routine
-
-#228. (Changed in MR20) dlg crashes on "()"
-
- The following token defintion will cause DLG to crash.
-
- #token "()"
-
- When there is a syntax error in a regular expression
- many of the dlg routines return a structure which has
- null pointers. When this is accessed by callers it
- generates the crash.
-
- I have attempted to fix the more common cases.
-
- Reported by Mengue Olivier (dolmen@bigfoot.com).
-
-#227. (Changed in MR20) Array overwrite
-
- Steveh Hand (sassth@unx.sas.com) reported a problem which
- was traced to a temporary array which was not properly
- resized for deeply nested blocks. This has been fixed.
-
-#226. (Changed in MR20) -pedantic conformance
-
- G. Hobbelt (i_a@mbh.org) and THM made many, many minor
- changes to create prototypes for all the functions and
- bring antlr, dlg, and sorcerer into conformance with
- the gcc -pedantic option.
-
- This may require uses to add pccts/h/pcctscfg.h to some
- files or makefiles in order to have __USE_PROTOS defined.
-
-#225 (Changed in MR20) AST stack adjustment in C mode
-
- The fix in #214 for AST stack adjustment in C mode missed
- some cases.
-
- Reported with fix by Ger Hobbelt (i_a@mbh.org).
-
-#224 (Changed in MR20) LL(1) and LL(2) with #pragma approx
-
- This may take a record for the oldest, most trival, lexical
- error in pccts. The regular expressions for LL(1) and LL(2)
- lacked an escape for the left and right parenthesis.
-
- Reported by Ger Hobbelt (i_a@mbh.org).
-
-#223 (Changed in MR20) Addition of IBM_VISUAL_AGE directory
-
- Build files for antlr, dlg, and sorcerer under IBM Visual Age
- have been contributed by Anton Sergeev (ags@mlc.ru). They have
- been placed in the pccts/IBM_VISUAL_AGE directory.
-
-#222 (Changed in MR20) Replace __STDC__ with __USE_PROTOS
-
- Most occurrences of __STDC__ replaced with __USE_PROTOS due to
- complaints from several users.
-
-#221 (Changed in MR20) Added #include for DLexerBase.h to PBlackBox.
-
- Added #include for DLexerBase.h to PBlackBox.
-
-#220 (Changed in MR19) strcat arguments reversed in #pred parse
-
- The arguments to strcat are reversed when creating a print
- name for a hash table entry for use with #pred feature.
-
- Problem diagnosed and fix reported by Scott Harrington
- (seh4@ix.netcom.com).
-
-#219. (Changed in MR19) C Mode routine zzfree_ast
-
- Changes to reduce use of recursion for AST trees with only right
- links or only left links in the C mode routine zzfree_ast.
-
- Implemented by SAKAI Kiyotaka (ksakai@isr.co.jp).
-
-#218. (Changed in MR19) Changes to support unsigned char in C mode
-
- Changes to antlr.h and err.h to fix omissions in use of zzchar_t
-
- Implemented by SAKAI Kiyotaka (ksakai@isr.co.jp).
-
-#217. (Changed in MR19) Error message when dlg -i and -CC options selected
-
- *** This change was rescinded by item #257 ***
-
- The parsers generated by pccts in C++ mode are not able to support the
- interactive lexer option (except, perhaps, when using the deferred fetch
- parser option.(Item #216).
-
- DLG now warns when both -i and -CC are selected.
-
- This warning was suggested by David Venditti (07751870267-0001@t-online.de).
-
-#216. (Changed in MR19) Defer token fetch for C++ mode
-
- Implemented by Volker H. Simonis (simonis@informatik.uni-tuebingen.de)
-
- Normally, pccts keeps the lookahead token buffer completely filled.
- This requires max(k,ck) tokens of lookahead. For some applications
- this can cause deadlock problems. For example, there may be cases
- when the parser can't tell when the input has been completely consumed
- until the parse is complete, but the parse can't be completed because
- the input routines are waiting for additional tokens to fill the
- lookahead buffer.
-
- When the ANTLRParser class is built with the pre-processor option
- ZZDEFER_FETCH defined, the fetch of new tokens by consume() is deferred
- until LA(i) or LT(i) is called.
-
- To test whether this option has been built into the ANTLRParser class
- use "isDeferFetchEnabled()".
-
- Using the -gd trace option with the default tracein() and traceout()
- routines will defeat the effort to defer the fetch because the
- trace routines print out information about the lookahead token at
- the start of the rule.
-
- Because the tracein and traceout routines are virtual it is
- easy to redefine them in your parser:
-

-
- The originals for those routines are pccts/h/AParser.cpp

-
- There was no obvious way to reset the lexer for reuse. The
- reset() method now does this.
-
- Suggested by David Venditti (07751870267-0001@t-online.de).
-
-#214. (Changed in MR19) C mode: Adjust AST stack pointer at exit
-
- In C mode the AST stack pointer needs to be reset if there will
- be multiple calls to the ANTLRx macros.
-
- Reported with fix by Paul D. Smith (psmith@baynetworks.com).
-
-#213. (Changed in MR18) Fatal error with -mrhoistk (k>1 hoisting)
-
- When rearranging code I forgot to un-comment a critical line of
- code that handles hoisting of predicates with k>1 lookahead. This
- is now fixed.

-
-#212. (Changed in MR17) Mac related changes by Kenji Tanaka
-
- Kenji Tanaka (kentar@osa.att.ne.jp) has made a number of changes for
- Macintosh users.
-
- a. The following Macintosh MPW files aid in installing pccts on Mac:
-
- pccts/MPW_Read_Me
-
- pccts/install68K.mpw
- pccts/installPPC.mpw
-
- pccts/antlr/antlr.r
- pccts/antlr/antlr68K.make
- pccts/antlr/antlrPPC.make
-
- pccts/dlg/dlg.r
- pccts/dlg/dlg68K.make
- pccts/dlg/dlgPPC.make
-
- pccts/sorcerer/sor.r
- pccts/sorcerer/sor68K.make
- pccts/sorcerer/sorPPC.make
-
- They completely replace the previous Mac installation files.
-
- b. The most significant is a change in the MAC_FILE_CREATOR symbol
- in pcctscfg.h:
-
- old: #define MAC_FILE_CREATOR 'MMCC' /* Metrowerks C/C++ Text files */
- new: #define MAC_FILE_CREATOR 'CWIE' /* Metrowerks C/C++ Text files */
-
- c. Added calls to special_fopen_actions() where necessary.
-
-#211. (Changed in MR16a) C++ style comment in dlg
-
- This has been fixed.
-
-#210. (Changed in MR16a) Sor accepts \r\n, \r, or \n for end-of-line
-
- A user requested that Sorcerer be changed to accept other forms
- of end-of-line.
-
-#209. (Changed in MR16) Name of files changed.
-
- Old: CHANGES_FROM_1.33
- New: CHANGES_FROM_133.txt
-
- Old: KNOWN_PROBLEMS
- New: KNOWN_PROBLEMS.txt
-
-#208. (Changed in MR16) Change in use of pccts #include files
-
- There were problems with MS DevStudio when mixing Sorcerer and
- PCCTS in the same source file. The problem is caused by the
- redefinition of setjmp in the MS header file setjmp.h. In
- setjmp.h the pre-processor symbol setjmp was redefined to be
- _setjmp. A later effort to execute #include <setjmp.h> resulted
- in an effort to #include <_setjmp.h>. I'm not sure whether this
- is a bug or a feature. In any case, I decided to fix it by
- avoiding the use of pre-processor symbols in #include statements
- altogether. This has the added benefit of making pre-compiled
- headers work again.
-
- I've replaced statements:
-
- old: #include PCCTS_SETJMP_H
- new: #include "pccts_setjmp.h"
-
- Where pccts_setjmp.h contains:
-
- #ifndef __PCCTS_SETJMP_H__
- #define __PCCTS_SETJMP_H__
-
- #ifdef PCCTS_USE_NAMESPACE_STD
- #include <Csetjmp>
- #else
- #include <setjmp.h>
- #endif
-
- #endif
-
- A similar change has been made for other standard header files
- required by pccts and sorcerer: stdlib.h, stdarg.h, stdio.h, etc.
-
- Reported by Jeff Vincent (JVincent@novell.com) and Dale Davis
- (DalDavis@spectrace.com).
-
-#207. (Changed in MR16) dlg reports an invalid range for: [\0x00-\0xff]
-
- dlg will report that this is an invalid range.
-
- Diagnosed by Piotr Eljasiak (eljasiak@no-spam.zt.gdansk.tpsa.pl):
-
- I think this problem is not specific to unsigned chars
- because dlg reports no error for the range [\0x00-\0xfe].
-
- I've found that information on range is kept in field
- letter (unsigned char) of Attrib struct. Unfortunately
- the letter value internally is for some reasons increased
- by 1, so \0xff is represented here as 0.
-
- That's why dlg complains about the range [\0x00-\0xff] in
- dlg_p.g:
-
- if ($$.letter > $2.letter) {
- error("invalid range ", zzline);
- }
-
- The fix is:
-
- if ($$.letter > $2.letter && 255 != $$2.letter) {
- error("invalid range ", zzline);
- }
-
-#206. (Changed in MR16) Free zzFAILtext in ANTLRParser destructor
-
- The ANTLRParser destructor now frees zzFAILtext.
-
- Problem and fix reported by Manfred Kogler (km@cast.uni-linz.ac.at).
-
-#205. (Changed in MR16) DLGStringReset argument now const
-
- Changed: void DLGStringReset(DLGChar *s) {...}
- To: void DLGStringReset(const DLGChar *s) {...}
-
- Suggested by Dale Davis (daldavis@spectrace.com)
-
-#204. (Changed in MR15a) Change __WATCOM__ to __WATCOMC__ in pcctscfg.h
-
- Reported by Oleg Dashevskii (olegdash@my-dejanews.com).
-
-#203. (Changed in MR15) Addition of sorcerer to distribution kit
-
- I have finally caved in to popular demand. The pccts 1.33mr15
- kit will include sorcerer. The separate sorcerer kit will be
- discontinued.
-
-#202. (Changed) in MR15) Organization of MS Dev Studio Projects in Kit
-
- Previously there was one workspace that contained projects for
- all three parts of pccts: antlr, dlg, and sorcerer. Now each
- part (and directory) has its own workspace/project and there
- is an additional workspace/project to build a library from the
- .cpp files in the pccts/h directory.
-
- The library build will create pccts_debug.lib or pccts_release.lib
- according to the configuration selected.
-
- If you don't want to build pccts 1.33MR15 you can download a
- ready-to-run kit for win32 from http://www.polhode.com/win32.zip.
- The ready-to-run for win32 includes executables, a pre-built static
- library for the .cpp files in the pccts/h directory, and a sample
- application
-
- You will need to define the environment variable PCCTS to point to
- the root of the pccts directory hierarchy.
-
-#201. (Changed in MR15) Several fixes by K.J. Cummings (cummings@peritus.com)
-
- Generation of SETJMP rather than SETJMP_H in gen.c.
-
- (Sor B19) Declaration of ref_vars_inits for ref_var_inits in
- pccts/sorcerer/sorcerer.h.
-
-#200. (Changed in MR15) Remove operator=() in AToken.h
-
- User reported that WatCom couldn't handle use of
- explicit operator =(). Replace with equivalent
- using cast operator.
-
-#199. (Changed in MR15) Don't allow use of empty #tokclass
-
- Change antlr.g to disallow empty #tokclass sets.
-
- Reported by Manfred Kogler (km@cast.uni-linz.ac.at).
-
-#198. Revised ANSI C grammar due to efforts by Manuel Kessler
-
- Manuel Kessler (mlkessler@cip.physik.uni-wuerzburg.de)
-
- Allow trailing ... in function parameter lists.
- Add bit fields.
- Allow old-style function declarations.
- Support cv-qualified pointers.
- Better checking of combinations of type specifiers.
- Release of memory for local symbols on scope exit.
- Allow input file name on command line as well as by redirection.
-
- and other miscellaneous tweaks.
-
- This is not part of the pccts distribution kit. It must be
- downloaded separately from:

-
-#197. (Changed in MR14) Resetting the lookahead buffer of the parser
-
- Explanation and fix by Sinan Karasu (sinan.karasu@boeing.com)
-
- Consider the code used to prime the lookahead buffer LA(i)
- of the parser when init() is called:
-
- void
- ANTLRParser::
- prime_lookahead()
- {
- int i;
- for(i=1;i<=LLk; i++) consume();
- dirty=0;
- //lap = 0; // MR14 - Sinan Karasu (sinan.karusu@boeing.com)
- //labase = 0; // MR14
- labase=lap; // MR14
- }
-
- When the parser is instantiated, lap=0,labase=0 is set.
-
- The "for" loop runs LLk times. In consume(), lap = lap +1 (mod LLk) is
- computed. Therefore, lap(before the loop) == lap (after the loop).
-
- Now the only problem comes in when one does an init() of the parser
- after an Eof has been seen. At that time, lap could be non zero.
- Assume it was lap==1. Now we do a prime_lookahead(). If LLk is 2,
- then
-
- consume()
- {
- NLA = inputTokens->getToken()->getType();
- dirty--;
- lap = (lap+1)&(LLk-1);
- }
-
- or expanding NLA,
-
- token_type[lap&(LLk-1)]) = inputTokens->getToken()->getType();
- dirty--;
- lap = (lap+1)&(LLk-1);
-
- so now we prime locations 1 and 2. In prime_lookahead it used to set
- lap=0 and labase=0. Now, the next token will be read from location 0,
- NOT 1 as it should have been.
-
- This was never caught before, because if a parser is just instantiated,
- then lap and labase are 0, the offending assignment lines are
- basically no-ops, since the for loop wraps around back to 0.
-
-#196. (Changed in MR14) Problems with "(alpha)? beta" guess
-
- Consider the following syntactic predicate in a grammar
- with 2 tokens of lookahead (k=2 or ck=2):
-
- rule : ( alpha )? beta ;
- alpha : S t ;
- t : T U
- | T
- ;
- beta : S t Z ;
-
- When antlr computes the prediction expression with one token
- of lookahead for alts 1 and 2 of rule t it finds an ambiguity.
-
- Because the grammar has a lookahead of 2 it tries to compute
- two tokens of lookahead for alts 1 and 2 of t. Alt 1 clearly
- has a lookahead of (T U). Alt 2 is one token long so antlr
- tries to compute the follow set of alt 2, which means finding
- the things which can follow rule t in the context of (alpha)?.
- This cannot be computed, because alpha is only part of a rule,
- and antlr can't tell what part of beta is matched by alpha and
- what part remains to be matched. Thus it impossible for antlr
- to properly determine the follow set of rule t.
-
- Prior to 1.33MR14, the follow of (alpha)? was computed as
- FIRST(beta) as a result of the internal representation of
- guess blocks.
-
- With MR14 the follow set will be the empty set for that context.
-
- Normally, one expects a rule appearing in a guess block to also
- appear elsewhere. When the follow context for this other use
- is "ored" with the empty set, the context from the other use
- results, and a reasonable follow context results. However if
- there is *no* other use of the rule, or it is used in a different
- manner then the follow context will be inaccurate - it was
- inaccurate even before MR14, but it will be inaccurate in a
- different way.
-
- For the example given earlier, a reasonable way to rewrite the
- grammar:
-
- rule : ( alpha )? beta
- alpha : S t ;
- t : T U
- | T
- ;
- beta : alpha Z ;
-
- If there are no other uses of the rule appearing in the guess
- block it will generate a test for EOF - a workaround for
- representing a null set in the lookahead tests.
-
- If you encounter such a problem you can use the -alpha option
- to get additional information:
-
- line 2: error: not possible to compute follow set for alpha
- in an "(alpha)? beta" block.
-
- With the antlr -alpha command line option the following information
- is inserted into the generated file:
-
- #if 0
-
- Trace of references leading to attempt to compute the follow set of
- alpha in an "(alpha)? beta" block. It is not possible for antlr to
- compute this follow set because it is not known what part of beta has
- already been matched by alpha and what part remains to be matched.
-
- Rules which make use of the incorrect follow set will also be incorrect
-
- 1 #token T alpha/2 line 7 brief.g
- 2 end alpha alpha/3 line 8 brief.g
- 2 end (...)? block at start/1 line 2 brief.g
-
- #endif
-
- At the moment, with the -alpha option selected the program marks
- any rules which appear in the trace back chain (above) as rules with
- possible problems computing follow set.
-
- Reported by Greg Knapen (gregory.knapen@bell.ca).
-
-#195. (Changed in MR14) #line directive not at column 1
-
- Under certain circunstances a predicate test could generate
- a #line directive which was not at column 1.
-
- Reported with fix by David Kågedal (davidk@lysator.liu.se)
- (http://www.lysator.liu.se/~davidk/).
-
-#194. (Changed in MR14) (C Mode only) Demand lookahead with #tokclass
-
- In C mode with the demand lookahead option there is a bug in the
- code which handles matches for #tokclass (zzsetmatch and
- zzsetmatch_wsig).
-
- The bug causes the lookahead pointer to get out of synchronization
- with the current token pointer.
-
- The problem was reported with a fix by Ger Hobbelt (hobbelt@axa.nl).
-
-#193. (Changed in MR14) Use of PCCTS_USE_NAMESPACE_STD
-
- The pcctscfg.h now contains the following definitions:
-
- #ifdef PCCTS_USE_NAMESPACE_STD
- #define PCCTS_STDIO_H <Cstdio>
- #define PCCTS_STDLIB_H <Cstdlib>
- #define PCCTS_STDARG_H <Cstdarg>
- #define PCCTS_SETJMP_H <Csetjmp>
- #define PCCTS_STRING_H <Cstring>
- #define PCCTS_ASSERT_H <Cassert>
- #define PCCTS_ISTREAM_H <istream>
- #define PCCTS_IOSTREAM_H <iostream>
- #define PCCTS_NAMESPACE_STD namespace std {}; using namespace std;
- #else
- #define PCCTS_STDIO_H <stdio.h>
- #define PCCTS_STDLIB_H <stdlib.h>
- #define PCCTS_STDARG_H <stdarg.h>
- #define PCCTS_SETJMP_H <setjmp.h>
- #define PCCTS_STRING_H <string.h>
- #define PCCTS_ASSERT_H <assert.h>
- #define PCCTS_ISTREAM_H <istream.h>
- #define PCCTS_IOSTREAM_H <iostream.h>
- #define PCCTS_NAMESPACE_STD
- #endif
-
- The runtime support in pccts/h uses these pre-processor symbols
- consistently.
-
- Also, antlr and dlg have been changed to generate code which uses
- these pre-processor symbols rather than having the names of the
- #include files hard-coded in the generated code.
-
- This required the addition of "#include pcctscfg.h" to a number of
- files in pccts/h.
-
- It appears that this sometimes causes problems for MSVC 5 in
- combination with the "automatic" option for pre-compiled headers.
- In such cases disable the "automatic" pre-compiled headers option.
-
- Suggested by Hubert Holin (Hubert.Holin@Bigfoot.com).
-
-#192. (Changed in MR14) Change setText() to accept "const ANTLRChar *"
-
- Changed ANTLRToken::setText(ANTLRChar *) to setText(const ANTLRChar *).
- This allows literal strings to be used to initialize tokens. Since
- the usual token implementation (ANTLRCommonToken) makes a copy of the
- input string, this was an unnecessary limitation.
-
- Suggested by Bob McWhirter (bob@netwrench.com).
-
-#191. (Changed in MR14) HP/UX aCC compiler compatibility problem
-
- Needed to explicitly declare zzINF_DEF_TOKEN_BUFFER_SIZE and
- zzINF_BUFFER_TOKEN_CHUNK_SIZE as ints in pccts/h/AParser.cpp.
-
- Reported by David Cook (dcook@bmc.com).

-
- This is a DLG stream class based on C++ istreams.
-
- Contributed by Hubert Holin (Hubert.Holin@Bigfoot.com).
-
-#187. (Changed in MR14) Rename config.h to pcctscfg.h
-
- The PCCTS configuration file has been renamed from config.h to
- pcctscfg.h. The problem with the original name is that it led
- to name collisions when pccts parsers were combined with other
- software.
-
- All of the runtime support routines in pccts/h/* have been
- changed to use the new name. Existing software can continue
- to use pccts/h/config.h. The contents of pccts/h/config.h is
- now just "#include "pcctscfg.h".
-
- I don't have a record of the user who suggested this.
-
-#186. (Changed in MR14) Pre-processor symbol DllExportPCCTS class modifier
-
- Classes in the C++ runtime support routines are now declared:
-
- class DllExportPCCTS className ....
-
- By default, the pre-processor symbol is defined as the empty
- string. This if for use by MSVC++ users to create DLL classes.
-
- Suggested by Manfred Kogler (km@cast.uni-linz.ac.at).
-
-#185. (Changed in MR14) Option to not use PCCTS_AST base class for ASTBase
-
- Normally, the ASTBase class is derived from PCCTS_AST which contains
- functions useful to Sorcerer. If these are not necessary then the
- user can define the pre-processor symbol "PCCTS_NOT_USING_SOR" which
- will cause the ASTBase class to replace references to PCCTS_AST with
- references to ASTBase where necessary.
-
- The class ASTDoublyLinkedBase will contain a pure virtual function
- shallowCopy() that was formerly defined in class PCCTS_AST.
-
- Suggested by Bob McWhirter (bob@netwrench.com).
-
-#184. (Changed in MR14) Grammars with no tokens generate invalid tokens.h
-
- Reported by Hubert Holin (Hubert.Holin@bigfoot.com).
-
-#183. (Changed in MR14) -f to specify file with names of grammar files
-
- In DEC/VMS it is difficult to specify very long command lines.
- The -f option allows one to place the names of the grammar files
- in a data file in order to bypass limitations of the DEC/VMS
- command language interpreter.
-
- Addition supplied by Bernard Giroud (b_giroud@decus.ch).
-
-#182. (Changed in MR14) Output directory option for DEC/VMS
-
- Fix some problems with the -o option under DEC/VMS.
-
- Fix supplied by Bernard Giroud (b_giroud@decus.ch).
-
-#181. (Changed in MR14) Allow chars > 127 in DLGStringInput::nextChar()
-
- Changed DLGStringInput to cast the character using (unsigned char)
- so that languages with character codes greater than 127 work
- without changes.
-
- Suggested by Manfred Kogler (km@cast.uni-linz.ac.at).
-
-#180. (Added in MR14) ANTLRParser::getEofToken()
-
- Added "ANTLRToken ANTLRParser::getEofToken() const" to match the
- setEofToken routine.
-
- Requested by Manfred Kogler (km@cast.uni-linz.ac.at).
-
-#179. (Fixed in MR14) Memory leak for BufFileInput subclass of DLGInputStream
-
- The BufFileInput class described in Item #142 neglected to release
- the allocated buffer when an instance was destroyed.
-
- Reported by Manfred Kogler (km@cast.uni-linz.ac.at).
-
-#178. (Fixed in MR14) Bug in "(alpha)? beta" guess blocks first sets
-
- In 1.33 vanilla, and all maintenance releases prior to MR14
- there is a bug in the handling of guess blocks which use the
- "long" form:
-
- (alpha)? beta
-
- inside a (...)*, (...)+, or {...} block.
-
- This problem does *not* apply to the case where beta is omitted
- or when the syntactic predicate is on the leading edge of an
- alternative.
-
- The problem is that both alpha and beta are stored in the
- syntax diagram, and that some analysis routines would fail
- to skip the alpha portion when it was not on the leading edge.
- Consider the following grammar with -ck 2:
-
- r : ( (A)? B )* C D
-
- | A B /* forces -ck 2 computation for old antlr */
- /* reports ambig for alts 1 & 2 */
-
- | B C /* forces -ck 2 computation for new antlr */
- /* reports ambig for alts 1 & 3 */
- ;
-
- The prediction expression for the first alternative should be
- LA(1)={B C} LA(2)={B C D}, but previous versions of antlr
- would compute the prediction expression as LA(1)={A C} LA(2)={B D}
-
- Reported by Arpad Beszedes (beszedes@inf.u-szeged.hu) who provided
- a very clear example of the problem and identified the probable cause.
-
-#177. (Changed in MR14) #tokdefs and #token with regular expression
-
- In MR13 the change described by Item #162 caused an existing
- feature of antlr to fail. Prior to the change it was possible
- to give regular expression definitions and actions to tokens
- which were defined via the #tokdefs directive.
-
- This now works again.
-
- Reported by Manfred Kogler (km@cast.uni-linz.ac.at).
-
-#176. (Changed in MR14) Support for #line in antlr source code
-
- Note: this was implemented by Arpad Beszedes (beszedes@inf.u-szeged.hu).
-
- In 1.33MR14 it is possible for a pre-processor to generate #line
- directives in the antlr source and have those line numbers and file
- names used in antlr error messages and in the #line directives
- generated by antlr.
-
- The #line directive may appear in the following forms:
-
- #line ll "sss" xx xx ...
-
- where ll represents a line number, "sss" represents the name of a file
- enclosed in quotation marks, and xxx are arbitrary integers.
-
- The following form (without "line") is not supported at the moment:
-
- # ll "sss" xx xx ...
-
- The result:
-
- zzline
-
- is replaced with ll from the # or #line directive
-
- FileStr[CurFile]
-
- is updated with the contents of the string (if any)
- following the line number
-
- Note
- ----
- The file-name string following the line number can be a complete
- name with a directory-path. Antlr generates the output files from
- the input file name (by replacing the extension from the file-name
- with .c or .cpp).
-
- If the input file (or the file-name from the line-info) contains
- a path:
-
- "../grammar.g"
-
- the generated source code will be placed in "../grammar.cpp" (i.e.
- in the parent directory). This is inconvenient in some cases
- (even the -o switch can not be used) so the path information is
- removed from the #line directive. Thus, if the line-info was
-
- #line 2 "../grammar.g"
-
- then the current file-name will become "grammar.g"
-
- In this way, the generated source code according to the grammar file
- will always be in the current directory, except when the -o switch
- is used.
-
-#175. (Changed in MR14) Bug when guess block appears at start of (...)*
-
- In 1.33 vanilla and all maintenance releases prior to 1.33MR14
- there is a bug when a guess block appears at the start of a (...)+.
- Consider the following k=1 (ck=1) grammar:
-
- rule :
- ( (STAR)? ZIP )* ID ;
-
- Prior to 1.33MR14, the generated code resembled:
-
- ...
- zzGUESS_BLOCK
- while ( 1 ) {
- if ( ! LA(1)==STAR) break;
- zzGUESS
- if ( !zzrv ) {
- zzmatch(STAR);
- zzCONSUME;
- zzGUESS_DONE
- zzmatch(ZIP);
- zzCONSUME;
- ...
-
- Note that the routine uses STAR for the prediction expression
- rather than ZIP. With 1.33MR14 the generated code resembles:
-
- ...
- while ( 1 ) {
- if ( ! LA(1)==ZIP) break;
- ...
-
- This problem existed only with (...)* blocks and was caused
- by the slightly more complicate graph which represents (...)*
- blocks. This caused the analysis routine to compute the first
- set for the alpha part of the "(alpha)? beta" rather than the
- beta part.
-
- Both (...)+ and {...} blocks handled the guess block correctly.
-
- Reported by Arpad Beszedes (beszedes@inf.u-szeged.hu) who provided
- a very clear example of the problem and identified the probable cause.
-
-#174. (Changed in MR14) Bug when action precedes syntactic predicate
-
- In 1.33 vanilla, and all maintenance releases prior to MR14,
- there was a bug when a syntactic predicate was immediately
- preceded by an action. Consider the following -ck 2 grammar:
-
- rule :
- <<int i;>>
- (alpha)? beta C
- | A B
- ;
-
- alpha : A ;
- beta : A B;
-
- Prior to MR14, the code generated for the first alternative
- resembled:
-
- ...
- zzGUESS
- if ( !zzrv && LA(1)==A && LA(2)==A) {
- alpha();
- zzGUESS_DONE
- beta();
- zzmatch(C);
- zzCONSUME;
- } else {
- ...
-
- The prediction expression (i.e. LA(1)==A && LA(2)==A) is clearly
- wrong because LA(2) should be matched to B (first[2] of beta is {B}).
-
- With 1.33MR14 the prediction expression is:
-
- ...
- if ( !zzrv && LA(1)==A && LA(2)==B) {
- alpha();
- zzGUESS_DONE
- beta();
- zzmatch(C);
- zzCONSUME;
- } else {
- ...
-
- This will only affect users in which alpha is shorter than
- than max(k,ck) and there is an action immediately preceding
- the syntactic predicate.
-
- This problem was reported by reported by Arpad Beszedes
- (beszedes@inf.u-szeged.hu) who provided a very clear example
- of the problem and identified the presence of the init-action
- as the likely culprit.

-#173. (Changed in MR13a) -glms for Microsoft style filenames with -gl
-
- With the -gl option antlr generates #line directives using the
- exact name of the input files specified on the command line.
- An oddity of the Microsoft C and C++ compilers is that they
- don't accept file names in #line directives containing "\"
- even though these are names from the native file system.
-
- With -glms option, the "\" in file names appearing in #line
- directives is replaced with a "/" in order to conform to
- Microsoft compiler requirements.
-
- Reported by Erwin Achermann (erwin.achermann@switzerland.org).
-
-#172. (Changed in MR13) \r\n in antlr source counted as one line
-
- Some MS software uses \r\n to indicate a new line. Antlr
- now recognizes this in counting lines.
-
- Reported by Edward L. Hepler (elh@ece.vill.edu).
-
-#171. (Changed in MR13) #tokclass L..U now allowed
-
- The following is now allowed:
-
- #tokclass ABC { A..B C }
-
- Reported by Dave Watola (dwatola@amtsun.jpl.nasa.gov)
-
-#170. (Changed in MR13) Suppression for predicates with lookahead depth >1
-
- In MR12 the capability for suppression of predicates with lookahead
- depth=1 was introduced. With MR13 this had been extended to
- predicates with lookahead depth > 1 and released for use by users
- on an experimental basis.
-
- Consider the following grammar with -ck 2 and the predicate in rule
- "a" with depth 2:
-
- r1 : (ab)* "@"
- ;
-
- ab : a
- | b
- ;
-
- a : (A B)? => <<p(LATEXT(2))>>? A B C
- ;
-
- b : A B C
- ;
-
- Normally, the predicate would be hoisted into rule r1 in order to
- determine whether to call rule "ab". However it should *not* be
- hoisted because, even if p is false, there is a valid alternative
- in rule b. With "-mrhoistk on" the predicate will be suppressed.
-
- If "-info p" command line option is present the following information
- will appear in the generated code:
-
- while ( (LA(1)==A)
- #if 0
-
- Part (or all) of predicate with depth > 1 suppressed by alternative
- without predicate
-
- pred << p(LATEXT(2))>>?
- depth=k=2 ("=>" guard) rule a line 8 t1.g
- tree context:
- (root = A
- B
- )
-
- The token sequence which is suppressed: ( A B )
- The sequence of references which generate that sequence of tokens:
-
- 1 to ab r1/1 line 1 t1.g
- 2 ab ab/1 line 4 t1.g
- 3 to b ab/2 line 5 t1.g
- 4 b b/1 line 11 t1.g
- 5 #token A b/1 line 11 t1.g
- 6 #token B b/1 line 11 t1.g
-
- #endif
-
- A slightly more complicated example:
-
- r1 : (ab)* "@"
- ;
-
- ab : a
- | b
- ;
-
- a : (A B)? => <<p(LATEXT(2))>>? (A B | D E)
- ;
-
- b : <<q(LATEXT(2))>>? D E
- ;
-
-
- In this case, the sequence (D E) in rule "a" which lies behind
- the guard is used to suppress the predicate with context (D E)
- in rule b.
-
- while ( (LA(1)==A || LA(1)==D)
- #if 0
-
- Part (or all) of predicate with depth > 1 suppressed by alternative
- without predicate
-
- pred << q(LATEXT(2))>>?
- depth=k=2 rule b line 11 t2.g
- tree context:
- (root = D
- E
- )
-
- The token sequence which is suppressed: ( D E )
- The sequence of references which generate that sequence of tokens:
-
- 1 to ab r1/1 line 1 t2.g
- 2 ab ab/1 line 4 t2.g
- 3 to a ab/1 line 4 t2.g
- 4 a a/1 line 8 t2.g
- 5 #token D a/1 line 8 t2.g
- 6 #token E a/1 line 8 t2.g
-
- #endif
- &&
- #if 0
-
- pred << p(LATEXT(2))>>?
- depth=k=2 ("=>" guard) rule a line 8 t2.g
- tree context:
- (root = A
- B
- )
-
- #endif
-
- (! ( LA(1)==A && LA(2)==B ) || p(LATEXT(2)) ) {
- ab();
- ...
-
-#169. (Changed in MR13) Predicate test optimization for depth=1 predicates
-
- When the MR12 generated a test of a predicate which had depth 1
- it would use the depth >1 routines, resulting in correct but
- inefficient behavior. In MR13, a bit test is used.
-
-#168. (Changed in MR13) Token expressions in context guards
-
- The token expressions appearing in context guards such as:
-
- (A B)? => <<test(LT(1))>>? someRule
-
- are computed during an early phase of antlr processing. As
- a result, prior to MR13, complex expressions such as:
-
- ~B
- L..U
- ~L..U
- TokClassName
- ~TokClassName
-
- were not computed properly. This resulted in incorrect
- context being computed for such expressions.
-
- In MR13 these context guards are verified for proper semantics
- in the initial phase and then re-evaluated after complex token
- expressions have been computed in order to produce the correct
- behavior.
-
- Reported by Arpad Beszedes (beszedes@inf.u-szeged.hu).
-
-#167. (Changed in MR13) ~L..U
-
- Prior to MR13, the complement of a token range was
- not properly computed.
-
-#166. (Changed in MR13) token expression L..U
-
- The token U was represented as an unsigned char, restricting
- the use of L..U to cases where U was assigned a token number
- less than 256. This is corrected in MR13.
-
-#165. (Changed in MR13) option -newAST
-
- To create ASTs from an ANTLRTokenPtr antlr usually calls
- "new AST(ANTLRTokenPtr)". This option generates a call
- to "newAST(ANTLRTokenPtr)" instead. This allows a user
- to define a parser member function to create an AST object.
-
- Similar changes for ASTBase::tmake and ASTBase::link were not
- thought necessary since they do not create AST objects, only
- use existing ones.
-
-#164. (Changed in MR13) Unused variable _astp
-
- For many compilations, we have lived with warnings about
- the unused variable _astp. It turns out that this varible
- can *never* be used because the code which references it was
- commented out.
-
- This investigation was sparked by a note from Erwin Achermann
- (erwin.achermann@switzerland.org).
-
-#163. (Changed in MR13) Incorrect makefiles for testcpp examples
-
- All the examples in pccts/testcpp/* had incorrect definitions
- in the makefiles for the symbol "CCC". Instead of CCC=CC they
- had CC=$(CCC).
-
- There was an additional problem in testcpp/1/test.g due to the
- change in ANTLRToken::getText() to a const member function
- (Item #137).
-
- Reported by Maurice Mass (maas@cuci.nl).
-
-#162. (Changed in MR13) Combining #token with #tokdefs
-
- When it became possible to change the print-name of a
- #token (Item #148) it became useful to give a #token
- statement whose only purpose was to giving a print name
- to the #token. Prior to this change this could not be
- combined with the #tokdefs feature.
-
-#161. (Changed in MR13) Switch -gxt inhibits generation of tokens.h
-
-#160. (Changed in MR13) Omissions in list of names for remap.h
-
- When a user selects the -gp option antlr creates a list
- of macros in remap.h to rename some of the standard
- antlr routines from zzXXX to userprefixXXX.
-
- There were number of omissions from the remap.h name
- list related to the new trace facility. This was reported,
- along with a fix, by Bernie Solomon (bernard@ug.eds.com).
-
-#159. (Changed in MR13) Violations of classic C rules
-
- There were a number of violations of classic C style in
- the distribution kit. This was reported, along with fixes,
- by Bernie Solomon (bernard@ug.eds.com).
-
-#158. (Changed in MR13) #header causes problem for pre-processors
-
- A user who runs the C pre-processor on antlr source suggested
- that another syntax be allowed. With MR13 such directives
- such as #header, #pragma, etc. may be written as "\#header",
- "\#pragma", etc. For escaping pre-processor directives inside
- a #header use something like the following:
-
- \#header
- <<
- \#include <stdio.h>
- >>
-
-#157. (Fixed in MR13) empty error sets for rules with infinite recursion
-
- When the first set for a rule cannot be computed due to infinite
- left recursion and it is the only alternative for a block then
- the error set for the block would be empty. This would result
- in a fatal error.
-
- Reported by Darin Creason (creason@genedax.com)
-
-#156. (Changed in MR13) DLGLexerBase::getToken() now public
-
-#155. (Changed in MR13) Context behind predicates can suppress
-
- With -mrhoist enabled the context behind a guarded predicate can
- be used to suppress other predicates. Consider the following grammar:
-
- r0 : (r1)+;
-
- r1 : rp
- | rq
- ;
- rp : <<p LATEXT(1)>>? B ;
- rq : (A)? => <<q LATEXT(1)>>? (A|B);
-
- In earlier versions both predicates "p" and "q" would be hoisted into
- rule r0. With MR12c predicate p is suppressed because the context which
- follows predicate q includes "B" which can "cover" predicate "p". In
- other words, in trying to decide in r0 whether to call r1, it doesn't
- really matter whether p is false or true because, either way, there is
- a valid choice within r1.
-
-#154. (Changed in MR13) Making hoist suppression explicit using <<nohoist>>
-
- A common error, even among experienced pccts users, is to code
- an init-action to inhibit hoisting rather than a leading action.
- An init-action does not inhibit hoisting.
-
- This was coded:
-
- rule1 : <<;>> rule2
-
- This is what was meant:
-
- rule1 : <<;>> <<;>> rule2
-
- With MR13, the user can code:
-
- rule1 : <<;>> <<nohoist>> rule2
-
- The following will give an error message:
-
- rule1 : <<nohoist>> rule2
-
- If the <<nohoist>> appears as an init-action rather than a leading
- action an error message is issued. The meaning of an init-action
- containing "nohoist" is unclear: does it apply to just one
- alternative or to all alternatives ?

-#153. (Changed in MR12b) Bug in computation of -mrhoist suppression set
-
- Consider the following grammar with k=1 and "-mrhoist on":
-
- r1 : (A)? => ((p>>? x /* l1 */
- | r2 /* l2 */
- ;
- r2 : A /* l4 */
- | (B)? => <<q>>? y /* l5 */
- ;
-
- In earlier versions the mrhoist routine would see that both l1 and
- l2 contained predicates and would assume that this prevented either
- from acting to suppress the other predicate. In the example above
- it didn't realize the A at line l4 is capable of suppressing the
- predicate at l1 even though alt l2 contains (indirectly) a predicate.
-
- This is fixed in MR12b.
-
- Reported by Reinier van den Born (reinier@vnet.ibm.com)
-
-#153. (Changed in MR12a) Bug in computation of -mrhoist suppression set
-
- An oversight similar to that described in Item #152 appeared in
- the computation of the set that "covered" a predicate. If a
- predicate expression included a term such as p=AND(q,r) the context
- of p was taken to be context(q) & context(r), when it should have
- been context(q) | context(r). This is fixed in MR12a.
-
-#152. (Changed in MR12) Bug in generation of predicate expressions
-
- The primary purpose for MR12 is to make quite clear that MR11 is
- obsolete and to fix the bug related to predicate expressions.
-
- In MR10 code was added to optimize the code generated for
- predicate expression tests. Unfortunately, there was a
- significant oversight in the code which resulted in a bug in
- the generation of code for predicate expression tests which
- contained predicates combined using AND:
-
- r0 : (r1)* "@" ;
- r1 : (AAA)? => <<p LATEXT(1)>>? r2 ;
- r2 : (BBB)? => <<q LATEXT(1)>>? Q
- | (BBB)? => <<r LATEXT(1)>>? Q
- ;
-
- In MR11 (and MR10 when using "-mrhoist on") the code generated
- for r0 to predict r1 would be equivalent to:
-
- if ( LA(1)==Q &&
- (LA(1)==AAA && LA(1)==BBB) &&
- ( p && ( q || r )) ) {
-
- This is incorrect because it expresses the idea that LA(1)
- *must* be AAA in order to attempt r1, and *must* be BBB to
- attempt r2. The result was that r1 became unreachable since
- both condition can not be simultaneously true.
-
- The general philosophy of code generation for predicates
- can be summarized as follows:
-
- a. If the context is true don't enter an alt
- for which the corresponding predicate is false.
-
- If the context is false then it is okay to enter
- the alt without evaluating the predicate at all.
-
- b. A predicate created by ORing of predicates has
- context which is the OR of their individual contexts.
-
- c. A predicate created by ANDing of predicates has
- (surprise) context which is the OR of their individual
- contexts.
-
- d. Apply these rules recursively.
-
- e. Remember rule (a)
-
- The correct code should express the idea that *if* LA(1) is
- AAA then p must be true to attempt r1, but if LA(1) is *not*
- AAA then it is okay to attempt r1, provided that *if* LA(1) is
- BBB then one of q or r must be true.
-
- if ( LA(1)==Q &&
- ( !(LA(1)==AAA || LA(1)==BBB) ||
- ( ! LA(1) == AAA || p) &&
- ( ! LA(1) == BBB || q || r ) ) ) {
-
- I believe this is fixed in MR12.

-
-#151a. (Changed in MR12) ANTLRParser::getLexer()
-
- As a result of several requests, I have added public methods to
- get a pointer to the lexer belonging to a parser.
-
- ANTLRTokenStream *ANTLRParser::getLexer() const
-
- Returns a pointer to the lexer being used by the
- parser. ANTLRTokenStream is the base class of
- DLGLexer
-
- ANTLRTokenStream *ANTLRTokenBuffer::getLexer() const
-
- Returns a pointer to the lexer being used by the
- ANTLRTokenBuffer. ANTLRTokenStream is the base
- class of DLGLexer
-
- You must manually cast the ANTLRTokenStream to your program's
- lexer class. Because the name of the lexer's class is not fixed.
- Thus it is impossible to incorporate it into the DLGLexerBase
- class.
-
-#151b.(Changed in MR12) ParserBlackBox member getLexer()
-
- The template class ParserBlackBox now has a member getLexer()
- which returns a pointer to the lexer.
-
-#150. (Changed in MR12) syntaxErrCount and lexErrCount now public
-
- See Item #127 for more information.
-
-#149. (Changed in MR12) antlr option -info o (letter o for orphan)
-
- If there is more than one rule which is not referenced by any
- other rule then all such rules are listed. This is useful for
- alerting one to rules which are not used, but which can still
- contribute to ambiguity. For example:
-
- start : a Z ;
- unused: a A ;
- a : (A)+ ;
-
- will cause an ambiguity report for rule "a" which will be
- difficult to understand if the user forgets about rule "unused"
- simply because it is not used in the grammar.
-
-#148. (Changed in MR11) #token names appearing in zztokens,token_tbl
-
- In a #token statement like the following:
-
- #token Plus "\+"
-
- the string "Plus" appears in the zztokens array (C mode) and
- token_tbl (C++ mode). This string is used in most error
- messages. In MR11 one has the option of using some other string,
- (e.g. "+") in those tables.
-
- In MR11 one can write:
-
- #token Plus ("+") "\+"
- #token RP ("(") "\("
- #token COM ("comment begin") "/\*"
-
- A #token statement is allowed to appear in more than one #lexclass
- with different regular expressions. However, the token name appears
- only once in the zztokens/token_tbl array. This means that only
- one substitute can be specified for a given #token name. The second
- attempt to define a substitute name (different from the first) will
- result in an error message.
-
-#147. (Changed in MR11) Bug in follow set computation
-
- There is a bug in 1.33 vanilla and all maintenance releases
- prior to MR11 in the computation of the follow set. The bug is
- different than that described in Item #82 and probably more
- common. It was discovered in the ansi.g grammar while testing
- the "ambiguity aid" (Item #119). The search for a bug started
- when the ambiguity aid was unable to discover the actual source
- of an ambiguity reported by antlr.
-
- The problem appears when an optimization of the follow set
- computation is used inappropriately. The result is that the
- follow set used is the "worst case". In other words, the error
- can lead to false reports of ambiguity. The good news is that
- if you have a grammar in which you have addressed all reported
- ambiguities you are ok. The bad news is that you may have spent
- time fixing ambiguities that were not real, or used k=2 when
- ck=2 might have been sufficient, and so on.
-
- The following grammar demonstrates the problem:
-
- ------------------------------------------------------------
- expr : ID ;
-
- start : stmt SEMI ;
-
- stmt : CASE expr COLON
- | expr SEMI
- | plain_stmt
- ;
-
- plain_stmt : ID COLON ;
- ------------------------------------------------------------
-
- When compiled with k=1 and ck=2 it will report:
-
- warning: alts 2 and 3 of the rule itself ambiguous upon
- { IDENTIFIER }, { COLON }
-
- When antlr analyzes "stmt" it computes the first[1] set of all
- alternatives. It finds an ambiguity between alts 2 and 3 for ID.
- It then computes the first[2] set for alternatives 2 and 3 to resolve
- the ambiguity. In computing the first[2] set of "expr" (which is
- only one token long) it needs to determine what could follow "expr".
- Under a certain combination of circumstances antlr forgets that it
- is trying to analyze "stmt" which can only be followed by SEMI and
- adds to the first[2] set of "expr" the "global" follow set (including
- "COLON") which could follow "expr" (under other conditions) in the
- phrase "CASE expr COLON".
-
-#146. (Changed in MR11) Option -treport for locating "difficult" alts
-
- It can be difficult to determine which alternatives are causing
- pccts to work hard to resolve an ambiguity. In some cases the
- ambiguity is successfully resolved after much CPU time so there
- is no message at all.
-
- A rough measure of the amount of work being peformed which is
- independent of the CPU speed and system load is the number of
- tnodes created. Using "-info t" gives information about the
- total number of tnodes created and the peak number of tnodes.
-
- Tree Nodes: peak 1300k created 1416k lost 0
-
- It also puts in the generated C or C++ file the number of tnodes
- created for a rule (at the end of the rule). However this
- information is not sufficient to locate the alternatives within
- a rule which are causing the creation of tnodes.
-
- Using:
-
- antlr -treport 100000 ....
-
- causes antlr to list on stdout any alternatives which require the
- creation of more than 100,000 tnodes, along with the lookahead sets
- for those alternatives.
-
- The following is a trivial case from the ansi.g grammar which shows
- the format of the report. This report might be of more interest
- in cases where 1,000,000 tuples were created to resolve the ambiguity.
-
- -------------------------------------------------------------------------
- There were 0 tuples whose ambiguity could not be resolved
- by full lookahead
- There were 157 tnodes created to resolve ambiguity between:
-
- Choice 1: statement/2 line 475 file ansi.g
- Choice 2: statement/3 line 476 file ansi.g
-
- Intersection of lookahead[1] sets:
-
- IDENTIFIER
-
- Intersection of lookahead[2] sets:
-
- LPARENTHESIS COLON AMPERSAND MINUS
- STAR PLUSPLUS MINUSMINUS ONESCOMPLEMENT
- NOT SIZEOF OCTALINT DECIMALINT
- HEXADECIMALINT FLOATONE FLOATTWO IDENTIFIER
- STRING CHARACTER

-#145. (Documentation) Generation of Expression Trees
-
- Item #99 was misleading because it implied that the optimization
- for tree expressions was available only for trees created by
- predicate expressions and neglected to mention that it required
- the use of "-mrhoist on". The optimization applies to tree
- expressions created for grammars with k>1 and for predicates with
- lookahead depth >1.
-
- In MR11 the optimized version is always used so the -mrhoist on
- option need not be specified.
-
-#144. (Changed in MR11) Incorrect test for exception group
-
- In testing for a rule's exception group the label a pointer
- is compared against '\0'. The intention is "*pointer".
-
- Reported by Jeffrey C. Fried (Jeff@Fried.net).
-
-#143. (Changed in MR11) Optional ";" at end of #token statement
-
- Fixes problem of:
-
- #token X "x"
-
- <<
- parser action

-
- Being confused with:
-
- #token X "x" <<lexical action>>
-
-#142. (Changed in MR11) class BufFileInput subclass of DLGInputStream
-
- Alexey Demakov (demakov@kazbek.ispras.ru) has supplied class
- BufFileInput derived from DLGInputStream which provides a
- function lookahead(char *string) to test characters in the
- input stream more than one character ahead.
-
- The default amount of lookahead is specified by the constructor
- and defaults to 8 characters. This does *not* include the one
- character of lookahead maintained internally by DLG in member "ch"
- and which is not available for testing via BufFileInput::lookahead().
-
- This is a useful class for overcoming the one-character-lookahead
- limitation of DLG without resorting to a lexer capable of
- backtracking (like flex) which is not integrated with antlr as is
- DLG.
-
- There are no restrictions on copying or using BufFileInput.* except
- that the authorship and related information must be retained in the
- source code.
-
- The class is located in pccts/h/BufFileInput.* of the kit.
-
-#141. (Changed in MR11) ZZDEBUG_CONSUME for ANTLRParser::consume()
-
- A debug aid has been added to file ANTLRParser::consume() in
- file AParser.cpp:
-
- #ifdef ZZDEBUG_CONSUME_ACTION
- zzdebug_consume_action();
- #endif

- Suggested by Sramji Ramanathan (ps@kumaran.com).
-
-#140. (Changed in MR11) #pred to define predicates
-
- +---------------------------------------------------+
- | Note: Assume "-prc on" for this entire discussion |
- +---------------------------------------------------+
-
- A problem with predicates is that each one is regarded as
- unique and capable of disambiguating cases where two
- alternatives have identical lookahead. For example:
-
- rule : <<pred(LATEXT(1))>>? A
- | <<pred(LATEXT(1))>>? A
- ;
-
- will not cause any error messages or warnings to be issued
- by earlier versions of pccts. To compare the text of the
- predicates is an incomplete solution.
-
- In 1.33MR11 I am introducing the #pred statement in order to
- solve some problems with predicates. The #pred statement allows
- one to give a symbolic name to a "predicate literal" or a
- "predicate expression" in order to refer to it in other predicate
- expressions or in the rules of the grammar.
-
- The predicate literal associated with a predicate symbol is C
- or C++ code which can be used to test the condition. A
- predicate expression defines a predicate symbol in terms of other
- predicate symbols using "!", "&&", and "||". A predicate symbol
- can be defined in terms of a predicate literal, a predicate
- expression, or *both*.
-
- When a predicate symbol is defined with both a predicate literal
- and a predicate expression, the predicate literal is used to generate
- code, but the predicate expression is used to check for two
- alternatives with identical predicates in both alternatives.
-
- Here are some examples of #pred statements:
-

-
- What is the purpose of this nonsense ?
-
- To understand how predicate symbols help, you need to realize that
- predicate symbols are used in two different ways with two different
- goals.
-
- a. Allow simplification of predicates which have been combined
- during predicate hoisting.
-
- b. Allow recognition of identical predicates which can't disambiguate
- alternatives with common lookahead.
-
- First we will discuss goal (a). Consider the following rule:
-
- rule0: rule1
- | ID
- | ...
- ;
-
- rule1: rule2
- | rule3
- ;
-
- rule2: <<isX(LATEXT(1))>>? ID ;
- rule3: <<!isX(LATEXT(1)>>? ID ;
-
- When the predicates in rule2 and rule3 are combined by hoisting
- to create a prediction expression for rule1 the result is:
-
- if ( LA(1)==ID
- && ( isX(LATEXT(1) || !isX(LATEXT(1) ) ) { rule1(); ...
-
- This is inefficient, but more importantly, can lead to false
- assumptions that the predicate expression distinguishes the rule1
- alternative with some other alternative with lookahead ID. In
- MR11 one can write:
-
- #pred IsX <<isX(LATEXT(1))>>?
-
- ...
-
- rule2: <<IsX>>? ID ;
- rule3: <<!IsX>>? ID ;
-
- During hoisting MR11 recognizes this as a special case and
- eliminates the predicates. The result is a prediction
- expression like the following:
-
- if ( LA(1)==ID ) { rule1(); ...
-
- Please note that the following cases which appear to be equivalent
- *cannot* be simplified by MR11 during hoisting because the hoisting
- logic only checks for a "!" in the predicate action, not in the
- predicate expression for a predicate symbol.
-
- *Not* equivalent and is not simplified during hoisting:
-
- #pred IsX <<isX(LATEXT(1))>>?
- #pred NotX <<!isX(LATEXT(1))>>?
- ...
- rule2: <<IsX>>? ID ;
- rule3: <<NotX>>? ID ;
-
- *Not* equivalent and is not simplified during hoisting:
-
- #pred IsX <<isX(LATEXT(1))>>?
- #pred NotX !IsX
- ...
- rule2: <<IsX>>? ID ;
- rule3: <<NotX>>? ID ;
-
- Now we will discuss goal (b).
-
- When antlr discovers that there is a lookahead ambiguity between
- two alternatives it attempts to resolve the ambiguity by searching
- for predicates in both alternatives. In the past any predicate
- would do, even if the same one appeared in both alternatives:
-
- rule: <<p(LATEXT(1))>>? X
- | <<p(LATEXT(1))>>? X
- ;
-
- The #pred statement is a start towards solving this problem.
- During ambiguity resolution (*not* predicate hoisting) the
- predicates for the two alternatives are expanded and compared.
- Consider the following example:
-
- #pred Upper <<isUpper(LATEXT(1))>>?
- #pred Lower <<isLower(LATEXT(1))>>?
- #pred Alpha <<isAlpha(LATEXT(1))>>? Upper || Lower
-
- rule0: rule1
- | <<Alpha>>? ID
- ;
-
- rule1:
- | rule2
- | rule3
- ...
- ;
-
- rule2: <<Upper>>? ID;
- rule3: <<Lower>>? ID;
-
- The definition of #pred Alpha expresses:
-
- a. to test the predicate use the C code "isAlpha(LATEXT(1))"
-
- b. to analyze the predicate use the information that
- Alpha is equivalent to the union of Upper and Lower,
-
- During ambiguity resolution the definition of Alpha is expanded
- into "Upper || Lower" and compared with the predicate in the other
- alternative, which is also "Upper || Lower". Because they are
- identical MR11 will report a problem.

-
- The comparison of the predicates for the two alternatives takes
- place without context information, which means that in some cases
- the predicates will be considered identical even though they operate
- on disjoint lookahead sets. Consider:
-
- #pred Alpha
-
- rule1: <<Alpha>>? ID
- | <<Alpha>>? Label
- ;
-
- Because the comparison of predicates takes place without context
- these will be considered identical. The reason for comparing
- without context is that otherwise it would be necessary to re-evaluate
- the entire predicate expression for each possible lookahead sequence.
- This would require more code to be written and more CPU time during
- grammar analysis, and it is not yet clear whether anyone will even make
- use of the new #pred facility.
-
- A temporary workaround might be to use different #pred statements
- for predicates you know have different context. This would avoid
- extraneous warnings.
-
- The above example might be termed a "false positive". Comparison
- without context will also lead to "false negatives". Consider the
- following example:
-
- #pred Alpha
- #pred Beta
-
- rule1: <<Alpha>>? A
- | rule2
- ;
-
- rule2: <<Alpha>>? A
- | <<Beta>>? B
- ;
-
- The predicate used for alt 2 of rule1 is (Alpha || Beta). This
- appears to be different than the predicate Alpha used for alt1.
- However, the context of Beta is B. Thus when the lookahead is A
- Beta will have no resolving power and Alpha will be used for both
- alternatives. Using the same predicate for both alternatives isn't
- very helpful, but this will not be detected with 1.33MR11.
-
- To properly handle this the predicate expression would have to be
- evaluated for each distinct lookahead context.
-
- To determine whether two predicate expressions are identical is
- difficult. The routine may fail to identify identical predicates.
-
- The #pred feature also compares predicates to see if a choice between
- alternatives which is resolved by a predicate which makes the second
- choice unreachable. Consider the following example:
-
- #pred A <<A(LATEXT(1)>>?
- #pred B <<B(LATEXT(1)>>?
- #pred A_or_B A || B
-
- r : s
- | t
- ;
- s : <<A_or_B>>? ID
- ;
- t : <<A>>? ID
- ;
-
- ----------------------------------------------------------------------------
- t11.g, line 5: warning: the predicate used to disambiguate the
- first choice of rule r
- (file t11.g alt 1 line 5 and alt 2 line 6)
- appears to "cover" the second predicate when compared without context.
- The second predicate may have no resolving power for some lookahead
- sequences.

-
-#137. (Changed in MR11) Token getType(), getText(), getLine() const members
-
- --------------------------------------------------------------------
- If you use ANTLRCommonToken this change probably does not affect you.
- --------------------------------------------------------------------
-
- For a long time it has bothered me that these accessor functions
- in ANTLRAbstractToken were not const member functions. I have
- refrained from changing them because it require users to modify
- existing token class definitions which are derived directly
- from ANTLRAbstractToken. I think it is now time.
-
- For those who are not used to C++, a "const member function" is a
- member function which does not modify its own object - the thing
- to which "this" points. This is quite different from a function
- which does not modify its arguments
-
- Most token definitions based on ANTLRAbstractToken have something like
- the following in order to create concrete definitions of the pure
- virtual methods in ANTLRAbstractToken:
-
- class MyToken : public ANTLRAbstractToken {
- ...
- ANTLRTokenType getType() {return _type; }
- int getLine() {return _line; }
- ANTLRChar * getText() {return _text; }
- ...
- }
-
- The required change is simply to put "const" following the function
- prototype in the header (.h file) and the definition file (.cpp if
- it is not inline):
-
- class MyToken : public ANTLRAbstractToken {
- ...
- ANTLRTokenType getType() const {return _type; }
- int getLine() const {return _line; }
- ANTLRChar * getText() const {return _text; }
- ...
- }
-
- This was originally proposed a long time ago by Bruce
- Guenter (bruceg@qcc.sk.ca).
-
-#136. (Changed in MR11) Added getLength() to ANTLRCommonToken
-
- Classes ANTLRCommonToken and ANTLRCommonTokenNoRefCountToken

-
- When this change is combined with the bugfix to the follow set cache

-#133. (Changed in 1.33MR11) Make trace options public in ANTLRParser

- 1.33MR11 discovered that it was inconvenient to have the
- trace facilities with protected access.
-
-#132. (Changed in 1.33MR11) Recognition of identical predicates in alts
-
- Prior to 1.33MR11, there would be no ambiguity warning when the
- very same predicate was used to disambiguate both alternatives:
-
- test: ref B
- | ref C
- ;
-
- ref : <<pred(LATEXT(1)>>? A
-
- In 1.33MR11 this will cause the warning:
-
- warning: the predicates used to disambiguate rule test
- (file v98.g alt 1 line 1 and alt 2 line 2)
- are identical and have no resolving power
-
- ----------------- Note -----------------
-
- This is different than the following case
-
- test: <<pred(LATEXT(1))>>? A B
- | <<pred(LATEXT(1)>>? A C
- ;
-
- In this case there are two distinct predicates
- which have exactly the same text. In the first
- example there are two references to the same
- predicate. The problem represented by this
- grammar will be addressed later.
-
-#131. (Changed in 1.33MR11) Case insensitive command line options
-
- Command line switches like "-CC" and keywords like "on", "off",
- and "stdin" are no longer case sensitive in antlr, dlg, and sorcerer.
-
-#130. (Changed in 1.33MR11) Changed ANTLR_VERSION to int from string
-
- The ANTLR_VERSION was not an integer, making it difficult to
- perform conditional compilation based on the antlr version.
-
- Henceforth, ANTLR_VERSION will be:
-
- (base_version * 10000) + release number
-
- thus 1.33MR11 will be: 133*100+11 = 13311
-
- Suggested by Rainer Janssen (Rainer.Janssen@Informatik.Uni-Oldenburg.DE).
-
-#129. (Changed in 1.33MR11) Addition of ANTLR_VERSION to <parserName>.h

-
-#128. (Changed in 1.33MR11) Redundant predicate code in (<<pred>>? ...)+
-
- Prior to 1.33MR11, the following grammar would generate
- redundant tests for the "while" condition.
-
- rule2 : (<<pred>>? X)+ X
- | B
- ;
-
- The code would resemble:
-
- if (LA(1)==X) {
- if (pred) {
- do {
- if (!pred) {zzfailed_pred(" pred");}
- zzmatch(X); zzCONSUME;
- } while (LA(1)==X && pred && pred);

-
-#125. (Changed in 1.33MR11) Lookahead for (guard)? && <<p>>? predicates
-
- When implementing the new style of guard predicate (Item #113)
- in 1.33MR10 I decided to temporarily ignore the problem of
- computing the "narrowest" lookahead context.
-
- Consider the following k=1 grammar:
-
- start : a
- | b
- ;
-
- a : (A)? && <<pred1(LATEXT(1))>>? ab ;
- b : (B)? && <<pred2(LATEXT(1))>>? ab ;
-
- ab : A | B ;
-
- In MR10 the context for both "a" and "b" was {A B} because this is
- the first set of rule "ab". Normally, this is not a problem because
- the predicate which follows the guard inhibits any ambiguity report
- by antlr.
-
- In MR11 the first set for rule "a" is {A} and for rule "b" it is {B}.
-
-#124. A Note on the New "&&" Style Guarded Predicates
-
- I've been asked several times, "What is the difference between
- the old "=>" style guard predicates and the new style "&&" guard
- predicates, and how do you choose one over the other" ?
-
- The main difference is that the "=>" does not apply the
- predicate if the context guard doesn't match, whereas
- the && form always does. What is the significance ?
-
- If you have a predicate which is not on the "leading edge"
- it is cannot be hoisted. Suppose you need a predicate that
- looks at LA(2). You must introduce it manually. The
- classic example is:
-
- castExpr :
- LP typeName RP
- | ....
- ;
-
- typeName : <<isTypeName(LATEXT(1))>>? ID
- | STRUCT ID
- ;
-
- The problem is that isTypeName() isn't on the leading edge
- of typeName, so it won't be hoisted into castExpr to help
- make a decision on which production to choose.
-
- The *first* attempt to fix it is this:
-
- castExpr :
- <<isTypeName(LATEXT(2))>>?
- LP typeName RP
- | ....
- ;
-
- Unfortunately, this won't work because it ignores
- the problem of STRUCT. The solution is to apply
- isTypeName() in castExpr if LA(2) is an ID and
- don't apply it when LA(2) is STRUCT:
-
- castExpr :
- (LP ID)? => <<isTypeName(LATEXT(2))>>?
- LP typeName RP
- | ....
- ;
-
- In conclusion, the "=>" style guarded predicate is
- useful when:
-
- a. the tokens required for the predicate
- are not on the leading edge
- b. there are alternatives in the expression
- selected by the predicate for which the
- predicate is inappropriate
-
- If (b) were false, then one could use a simple
- predicate (assuming "-prc on"):
-
- castExpr :
- <<isTypeName(LATEXT(2))>>?
- LP typeName RP
- | ....
- ;
-
- typeName : <<isTypeName(LATEXT(1))>>? ID
- ;
-
- So, when do you use the "&&" style guarded predicate ?
-
- The new-style "&&" predicate should always be used with
- predicate context. The context guard is in ADDITION to
- the automatically computed context. Thus it useful for
- predicates which depend on the token type for reasons
- other than context.
-
- The following example is contributed by Reinier van den Born
- (reinier@vnet.ibm.com).
-
- +-------------------------------------------------------------------------+
- | This grammar has two ways to call functions: |
- | |
- | - a "standard" call syntax with parens and comma separated args |
- | - a shell command like syntax (no parens and spacing separated args) |
- | |
- | The former also allows a variable to hold the name of the function, |
- | the latter can also be used to call external commands. |
- | |
- | The grammar (simplified) looks like this: |
- | |
- | fun_call : ID "(" { expr ("," expr)* } ")" |
- | /* ID is function name */ |
- | | "@" ID "(" { expr ("," expr)* } ")" |
- | /* ID is var containing fun name */ |
- | ; |
- | |
- | command : ID expr* /* ID is function name */ |
- | | path expr* /* path is external command name */ |
- | ; |
- | |
- | path : ID /* left out slashes and such */ |
- | | "@" ID /* ID is environment var */ |
- | ; |
- | |
- | expr : .... |
- | | "(" expr ")"; |
- | |
- | call : fun_call |
- | | command |
- | ; |
- | |
- | Obviously the call is wildly ambiguous. This is more or less how this |
- | is to be resolved: |
- | |
- | A call begins with an ID or an @ followed by an ID. |
- | |
- | If it is an ID and if it is an ext. command name -> command |
- | if followed by a paren -> fun_call |
- | otherwise -> command |
- | |
- | If it is an @ and if the ID is a var name -> fun_call |
- | otherwise -> command |
- | |
- | One can implement these rules quite neatly using && predicates: |
- | |
- | call : ("@" ID)? && <<isVarName(LT(2))>>? fun_call |
- | | (ID)? && <<isExtCmdName>>? command |
- | | (ID "(")? fun_call |
- | | command |
- | ; |
- | |
- | This can be done better, so it is not an ideal example, but it |
- | conveys the principle. |

-
- The user can ask for additional information on ambiguities reported

-
- This feature is enabled using the "-aa" (Ambiguity Aid) option.
-
- The following options control the reporting of ambiguities:
-
- -aa ruleName Selects reporting by name of rule
- -aa lineNumber Selects reporting by line number
- (file name not compared)
-
- -aam Selects "multiple" reporting for a token
- in the intersection set of the
- alternatives.
-
- For instance, the token ID may appear dozens
- of times in various paths as the program
- explores the rules which are reachable from
- the point of an ambiguity. With option -aam
- every possible path the search program
- encounters is reported.
-
- Without -aam only the first encounter is
- reported. This may result in incomplete
- information, but the information may be
- sufficient and much shorter.
-
- -aad depth Selects the depth of the search.
- The default value is 1.
-
- The number of paths to be searched, and the
- size of the report can grow geometrically
- with the -ck value if a full search for all
- contributions to the source of the ambiguity
- is explored.
-
- The depth represents the number of tokens
- in the lookahead set which are matched against
- the set of ambiguous tokens. A depth of 1
- means that the search stops when a lookahead
- sequence of just one token is matched.
-
- A k=1 ck=6 grammar might generate 5,000 items
- in a report if a full depth 6 search is made
- with the Ambiguity Aid. The source of the
- problem may be in the first token and obscured
- by the volume of data - I hesitate to call
- it information.
-
- When the user selects a depth > 1, the search
- is first performed at depth=1 for both
- alternatives, then depth=2 for both alternatives,
- etc.

- For a linear lookahead set ambiguity (where k=1 or for k>1 but
- when all lookahead sets [i] with i<k all have degree one) the
- reports appear in the following order:
-
- for (depth=1 ; depth <= "-aad depth" ; depth++) {
- for (alternative=1; alternative <=2 ; alternative++) {
- while (matches-are-found) {
- group++;
- print-report
- };
- };
- };
-
- For reporting a k-tuple ambiguity, the reports appear in the
- following order:
-
- for (depth=1 ; depth <= "-aad depth" ; depth++) {
- while (matches-are-found) {
- for (alternative=1; alternative <=2 ; alternative++) {
- group++;
- print-report
- };
- };
- };
-
- This is because matches are generated in different ways for
- linear lookahead and k-tuples.

-#118. (Changed in 1.33MR11) DEC VMS makefile and VMS related changes
-
- Revised makefiles for DEC/VMS operating system for antlr, dlg,
- and sorcerer.
-
- Reduced names of routines with external linkage to less than 32
- characters to conform to DEC/VMS linker limitations.
-
- Jean-Francois Pieronne discovered problems with dlg and antlr
- due to the VMS linker not being case sensitive for names with
- external linkage. In dlg the problem was with "className" and
- "ClassName". In antlr the problem was with "GenExprSets" and
- "genExprSets".
-
- Added genmms, a version of genmk for the DEC/VMS version of make.
- The source is in directory pccts/support/DECmms.
-
- All VMS contributions by Jean-Francois Pieronne (jfp@iname.com).

-#117. (Changed in 1.33MR10) new EXPERIMENTAL predicate hoisting code
-
- The hoisting of predicates into rules to create prediction
- expressions is a problem in antlr. Consider the following
- example (k=1 with -prc on):
-
- start : (a)* "@" ;
- a : b | c ;
- b : <<isUpper(LATEXT(1))>>? A ;
- c : A ;
-
- Prior to 1.33MR10 the code generated for "start" would resemble:
-
- while {
- if (LA(1)==A &&
- (!LA(1)==A || isUpper())) {
- a();
- }
- };
-
- This code is wrong because it makes rule "c" unreachable from
- "start". The essence of the problem is that antlr fails to
- recognize that there can be a valid alternative within "a" even
- when the predicate <<isUpper(LATEXT(1))>>? is false.
-
- In 1.33MR10 with -mrhoist the hoisting of the predicate into
- "start" is suppressed because it recognizes that "c" can
- cover all the cases where the predicate is false:
-
- while {
- if (LA(1)==A) {
- a();
- }
- };
-
- With the antlr "-info p" switch the user will receive information
- about the predicate suppression in the generated file:
-
- --------------------------------------------------------------
- #if 0
-
- Hoisting of predicate suppressed by alternative without predicate.
- The alt without the predicate includes all cases where
- the predicate is false.
-
- WITH predicate: line 7 v1.g
- WITHOUT predicate: line 7 v1.g
-
- The context set for the predicate:
-
- A
-
- The lookahead set for the alt WITHOUT the semantic predicate:
-
- A
-
- The predicate:
-
- pred << isUpper(LATEXT(1))>>?
- depth=k=1 rule b line 9 v1.g
- set context:
- A
- tree context: null
-
- Chain of referenced rules:
-
- #0 in rule start (line 5 v1.g) to rule a
- #1 in rule a (line 7 v1.g)
-
- #endif
- --------------------------------------------------------------
-
- A predicate can be suppressed by a combination of alternatives
- which, taken together, cover a predicate:
-
- start : (a)* "@" ;
-
- a : b | ca | cb | cc ;
-
- b : <<isUpper(LATEXT(1))>>? ( A | B | C ) ;
-
- ca : A ;
- cb : B ;
- cc : C ;
-
- Consider a more complex example in which "c" covers only part of
- a predicate:
-
- start : (a)* "@" ;
-
- a : b
- | c
- ;
-
- b : <<isUpper(LATEXT(1))>>?
- ( A
- | X
- );
-
- c : A
- ;
-
- Prior to 1.33MR10 the code generated for "start" would resemble:
-
- while {
- if ( (LA(1)==A || LA(1)==X) &&
- (! (LA(1)==A || LA(1)==X) || isUpper()) {
- a();
- }
- };
-
- With 1.33MR10 and -mrhoist the predicate context is restricted to
- the non-covered lookahead. The code resembles:
-
- while {
- if ( (LA(1)==A || LA(1)==X) &&
- (! (LA(1)==X) || isUpper()) {
- a();
- }
- };
-
- With the antlr "-info p" switch the user will receive information
- about the predicate restriction in the generated file:
-
- --------------------------------------------------------------
- #if 0
-
- Restricting the context of a predicate because of overlap
- in the lookahead set between the alternative with the
- semantic predicate and one without
- Without this restriction the alternative without the predicate
- could not be reached when input matched the context of the
- predicate and the predicate was false.
-
- WITH predicate: line 11 v4.g
- WITHOUT predicate: line 12 v4.g
-
- The original context set for the predicate:
-
- A X
-
- The lookahead set for the alt WITHOUT the semantic predicate:
-
- A
-
- The intersection of the two sets
-
- A
-
- The original predicate:
-
- pred << isUpper(LATEXT(1))>>?
- depth=k=1 rule b line 15 v4.g
- set context:
- A X
- tree context: null
-
- The new (modified) form of the predicate:
-
- pred << isUpper(LATEXT(1))>>?
- depth=k=1 rule b line 15 v4.g
- set context:
- X
- tree context: null
-
- #endif
- --------------------------------------------------------------
-
- The bad news about -mrhoist:
-
- (a) -mrhoist does not analyze predicates with lookahead
- depth > 1.
-
- (b) -mrhoist does not look past a guarded predicate to
- find context which might cover other predicates.
-
- For these cases you might want to use syntactic predicates.
- When a semantic predicate fails during guess mode the guess
- fails and the next alternative is tried.
-
- Limitation (a) is illustrated by the following example:
-
- start : (stmt)* EOF ;
-
- stmt : cast
- | expr
- ;
- cast : <<isTypename(LATEXT(2))>>? LP ID RP ;
-
- expr : LP ID RP ;
-
- This is not much different from the first example, except that
- it requires two tokens of lookahead context to determine what
- to do. This predicate is NOT suppressed because the current version
- is unable to handle predicates with depth > 1.
-
- A predicate can be combined with other predicates during hoisting.
- In those cases the depth=1 predicates are still handled. Thus,
- in the following example the isUpper() predicate will be suppressed
- by line #4 when hoisted from "bizarre" into "start", but will still
- be present in "bizarre" in order to predict "stmt".
-
- start : (bizarre)* EOF ; // #1
- // #2
- bizarre : stmt // #3
- | A // #4
- ;
-
- stmt : cast
- | expr
- ;
-
- cast : <<isTypename(LATEXT(2))>>? LP ID RP ;
-
- expr : LP ID RP ;
- | <<isUpper(LATEXT(1))>>? A
-
- Limitation (b) is illustrated by the following example of a
- context guarded predicate:
-
- rule : (A)? <<p>>? // #1
- (A // #2
- |B // #3
- ) // #4
- | <<q>> B // #5
- ;
-
- Recall that this means that when the lookahead is NOT A then
- the predicate "p" is ignored and it attempts to match "A|B".
- Ideally, the "B" at line #3 should suppress predicate "q".
- However, the current version does not attempt to look past
- the guard predicate to find context which might suppress other
- predicates.
-
- In some cases -mrhoist will lead to the reporting of ambiguities
- which were not visible before:
-
- start : (a)* "@";
- a : bc | d;
- bc : b | c ;
-
- b : <<isUpper(LATEXT(1))>>? A;
- c : A ;
-
- d : A ;
-
- In this case there is a true ambiguity in "a" between "bc" and "d"
- which can both match "A". Without -mrhoist the predicate in "b"
- is hoisted into "a" and there is no ambiguity reported. However,
- with -mrhoist, the predicate in "b" is suppressed by "c" (as it
- should be) making the ambiguity in "a" apparent.
-
- The motivations for these changes were hoisting problems reported
- by Reinier van den Born (reinier@vnet.ibm.com) and several others.
-
-#116. (Changed in 1.33MR10) C++ mode: tracein/traceout rule name is (const char *)
-
- The prototype for C++ mode routine tracein (and traceout) has changed from
- "char *" to "const char *".
-
-#115. (Changed in 1.33MR10) Using guess mode with exception handlers in C mode
-
- The definition of the C mode macros zzmatch_wsig and zzsetmatch_wsig
- neglected to consider guess mode. When control passed to the rule's
- parse exception handler the routine would exit without ever closing the
- guess block. This would lead to unpredictable behavior.
-
- In 1.33MR10 the behavior of exceptions in C mode and C++ mode should be
- identical.
-
-#114. (Changed in 1.33MR10) difference in [zz]resynch() between C and C++ modes
-
- There was a slight difference in the way C and C++ mode resynchronized
- following a parsing error. The C routine would sometimes skip an extra
- token before attempting to resynchronize.
-
- The C routine was changed to match the C++ routine.
-
-#113. (Changed in 1.33MR10) new context guarded pred: (g)? && <<p>>? expr
-
- The existing context guarded predicate:
-
- rule : (guard)? => <<p>>? expr
- | next_alternative
- ;
-
- generates code which resembles:
-
- if (lookahead(expr) && (!guard || pred)) {
- expr()
- } else ....
-
- This is not suitable for some applications because it allows
- expr() to be invoked when the predicate is false. This is
- intentional because it is meant to mimic automatically computed
- predicate context.
-
- The new context guarded predicate uses the guard information
- differently because it has a different goal. Consider:
-
- rule : (guard)? && <<p>>? expr
- | next_alternative
- ;
-
- The new style of context guarded predicate is equivalent to:
-
- rule : <<guard==true && pred>>? expr
- | next_alternative
- ;
-
- It generates code which resembles:
-
- if (lookahead(expr) && guard && pred) {
- expr();
- } else ...
-
- Both forms of guarded predicates severely restrict the form of
- the context guard: it can contain no rule references, no
- (...)*, no (...)+, and no {...}. It may contain token and
- token class references, and alternation ("|").
-
- Addition for 1.33MR11: in the token expression all tokens must
- be at the same height of the token tree:
-
- (A ( B | C))? && ... is ok (all height 2)
- (A ( B | ))? && ... is not ok (some 1, some 2)
- (A B C D | E F G H)? && ... is ok (all height 4)
- (A B C D | E )? && ... is not ok (some 4, some 1)
-
- This restriction is required in order to properly compute the lookahead
- set for expressions like:
-
- rule1 : (A B C)? && <<pred>>? rule2 ;
- rule2 : (A|X) (B|Y) (C|Z);
-
- This addition was suggested by Rienier van den Born (reinier@vnet.ibm.com)
-
-#112. (Changed in 1.33MR10) failed validation predicate in C guess mode
-
- John Lilley (jlilley@empathy.com) suggested that failed validation
- predicates abort a guess rather than reporting a failed error.
- This was installed in C++ mode (Item #4). Only now was it noticed
- that the fix was never installed for C mode.
-
-#111. (Changed in 1.33MR10) moved zzTRACEIN to before init action
-
- When the antlr -gd switch is present antlr generates calls to
- zzTRACEIN at the start of a rule and zzTRACEOUT at the exit
- from a rule. Prior to 1.33MR10 Tthe call to zzTRACEIN was
- after the init-action, which could cause confusion because the
- init-actions were reported with the name of the enclosing rule,
- rather than the active rule.
-
-#110. (Changed in 1.33MR10) antlr command line copied to generated file
-
- The antlr command line is now copied to the generated file near
- the start.
-
-#109. (Changed in 1.33MR10) improved trace information
-
- The quality of the trace information provided by the "-gd"
- switch has been improved significantly. Here is an example
- of the output from a test program. It shows the rule name,
- the first token of lookahead, the call depth, and the guess
- status:
-
- exit rule gusxx {"?"} depth 2
- enter rule gusxx {"?"} depth 2
- enter rule gus1 {"o"} depth 3 guessing
- guess done - returning to rule gus1 {"o"} at depth 3
- (guess mode continues - an enclosing guess is still active)
- guess done - returning to rule gus1 {"Z"} at depth 3
- (guess mode continues - an enclosing guess is still active)
- exit rule gus1 {"Z"} depth 3 guessing
- guess done - returning to rule gusxx {"o"} at depth 2 (guess mode ends)
- enter rule gus1 {"o"} depth 3
- guess done - returning to rule gus1 {"o"} at depth 3 (guess mode ends)
- guess done - returning to rule gus1 {"Z"} at depth 3 (guess mode ends)
- exit rule gus1 {"Z"} depth 3
- line 1: syntax error at "Z" missing SC
- ...
-
- Rule trace reporting is controlled by the value of the integer
- [zz]traceOptionValue: when it is positive tracing is enabled,
- otherwise it is disabled. Tracing during guess mode is controlled
- by the value of the integer [zz]traceGuessOptionValue. When
- it is positive AND [zz]traceOptionValue is positive rule trace
- is reported in guess mode.
-
- The values of [zz]traceOptionValue and [zz]traceGuessOptionValue
- can be adjusted by subroutine calls listed below.
-
- Depending on the presence or absence of the antlr -gd switch
- the variable [zz]traceOptionValueDefault is set to 0 or 1. When
- the parser is initialized or [zz]traceReset() is called the
- value of [zz]traceOptionValueDefault is copied to [zz]traceOptionValue.
- The value of [zz]traceGuessOptionValue is always initialzed to 1,
- but, as noted earlier, nothing will be reported unless
- [zz]traceOptionValue is also positive.
-
- When the parser state is saved/restored the value of the trace
- variables are also saved/restored. If a restore causes a change in
- reporting behavior from on to off or vice versa this will be reported.
-
- When the -gd option is selected, the macro "#define zzTRACE_RULES"
- is added to appropriate output files.
-
- C++ mode
- --------
- int traceOption(int delta)
- int traceGuessOption(int delta)
- void traceReset()
- int traceOptionValueDefault
-
- C mode
- --------
- int zzTraceOption(int delta)
- int zzTraceGuessOption(int delta)
- void zzTraceReset()
- int zzTraceOptionValueDefault
-
- The argument "delta" is added to the traceOptionValue. To
- turn on trace when inside a particular rule one:
-
- rule : <<traceOption(+1);>>
- (
- rest-of-rule
- )
- <<traceOption(-1);>>
- ; /* fail clause */ <<traceOption(-1);>>
-
- One can use the same idea to turn *off* tracing within a
- rule by using a delta of (-1).
-
- An improvement in the rule trace was suggested by Sramji
- Ramanathan (ps@kumaran.com).
-
-#108. A Note on Deallocation of Variables Allocated in Guess Mode
-
- NOTE
- ------------------------------------------------------
- This mechanism only works for heap allocated variables
- ------------------------------------------------------
-
- The rewrite of the trace provides the machinery necessary
- to properly free variables or undo actions following a
- failed guess.
-
- The macro zzUSER_GUESS_HOOK(guessSeq,zzrv) is expanded
- as part of the zzGUESS macro. When a guess is opened
- the value of zzrv is 0. When a longjmp() is executed to
- undo the guess, the value of zzrv will be 1.
-
- The macro zzUSER_GUESS_DONE_HOOK(guessSeq) is expanded
- as part of the zzGUESS_DONE macro. This is executed
- whether the guess succeeds or fails as part of closing
- the guess.
-
- The guessSeq is a sequence number which is assigned to each
- guess and is incremented by 1 for each guess which becomes
- active. It is needed by the user to associate the start of
- a guess with the failure and/or completion (closing) of a
- guess.
-
- Guesses are nested. They must be closed in the reverse
- of the order that they are opened.
-
- In order to free memory used by a variable during a guess
- a user must write a routine which can be called to
- register the variable along with the current guess sequence
- number provided by the zzUSER_GUESS_HOOK macro. If the guess
- fails, all variables tagged with the corresponding guess
- sequence number should be released. This is ugly, but
- it would require a major rewrite of antlr 1.33 to use
- some mechanism other than setjmp()/longjmp().
-
- The order of calls for a *successful* guess would be:
-
- zzUSER_GUESS_HOOK(guessSeq,0);
- zzUSER_GUESS_DONE_HOOK(guessSeq);
-
- The order of calls for a *failed* guess would be:
-
- zzUSER_GUESS_HOOK(guessSeq,0);
- zzUSER_GUESS_HOOK(guessSeq,1);
- zzUSER_GUESS_DONE_HOOK(guessSeq);
-
- The default definitions of these macros are empty strings.
-
- Here is an example in C++ mode. The zzUSER_GUESS_HOOK and
- zzUSER_GUESS_DONE_HOOK macros and myGuessHook() routine
- can be used without change in both C and C++ versions.

-
- Remember:

- (a) Only init-actions are executed during guess mode.
- (b) A rule can be invoked multiple times during guess mode.
- (c) If the guess succeeds the rule will be called once more

- This means that the init-action might need to distinguish
- between guess mode and non-guess mode using the variable
- [zz]guessing.

- zzGUESS
- if (!zzrv && LA(1)==ID) { <==== line #1
- alpha
- zzGUESS_DONE
- beta
- } else {
- if (! zzrv) zzGUESS_DONE <==== line #2a
- ....
-
- However, in some cases line #2 was rendered:
-
- if (guessing) zzGUESS_DONE <==== line #2b
-
- This would work for simple test cases, but would fail in
- some cases where there was a guess while another guess was active.
- One kind of failure would be to match up the zzGUESS_DONE at line
- #2b with the "outer" guess which was still active. The outer
- guess would "succeed" when only the inner guess should have
- succeeded.
-
- In 1.33MR10 the behavior of zzGUESS and zzGUESS_FAIL in C and
- and C++ mode should be identical.
-
- The same problem appears in 1.33 vanilla in some places. For
- example:
-
- start : { (sub)? } ;
-
- or:
-
- start : (
- B
- | ( sub )?
- | C
- )+
- ;
-
- generates incorrect code.
-
- The general principle is:
-
- (a) use [zz]guessing only when deciding between a call to zzFAIL
- or zzGUESS_FAIL
-
- (b) use zzrv in all other cases
-
- This problem was discovered while testing changes to item #105.
- I believe this is now fixed. My apologies.
-
-#105. (Changed in 1.33MR10) guess block as single alt of (...)+
-
- Prior to 1.33MR10 the following constructs:
-
- rule_plus : (
- (sub)?
- )+
- ;
-
- rule_star : (
- (sub)?
- )*
- ;
-
- generated incorrect code for the guess block (which could result
- in runtime errors) because of an incorrect optimization of a
- block with only a single alternative.
-
- The fix caused some changes to the fix described in Item #49
- because there are now three code generation sequences for (...)+
- blocks containing a guess block:
-
- a. single alternative which is a guess block
- b. multiple alternatives in which the last is a guess block
- c. all other cases
-
- Forms like "rule_star" can have unexpected behavior when there
- is a syntax error: if the subrule "sub" is not matched *exactly*
- then "rule_star" will consume no tokens.
-
- Reported by Esa Pulkkinen (esap@cs.tut.fi).
-
-#104. (Changed in 1.33MR10) -o option for dlg
-
- There was problem with the code added by item #74 to handle the
- -o option of dlg. This should fix it.
-
-#103. (Changed in 1.33MR10) ANDed semantic predicates
-
- Rescinded.
-
- The optimization was a mistake.
- The resulting problem is described in Item #150.
-
-#102. (Changed in 1.33MR10) allow "class parser : .... {"
-
- The syntax of the class statement ("class parser-name {")
- has been extended to allow for the specification of base
- classes. An arbirtrary number of tokens may now appear
- between the class name and the "{". They are output
- again when the class declaration is generated. For
- example:
-
- class Parser : public MyBaseClassANTLRparser {
-
- This was suggested by a user, but I don't have a record
- of who it was.
-
-#101. (Changed in 1.33MR10) antlr -info command line switch
-
- -info
-
- p - extra predicate information in generated file
-
- t - information about tnode use:
- at the end of each rule in generated file
- summary on stderr at end of program
-
- m - monitor progress
- prints name of each rule as it is started
- flushes output at start of each rule
-
- f - first/follow set information to stdout
-
- 0 - no operation (added in 1.33MR11)
-
- The options may be combined and may appear in any order.
- For example:
-
- antlr -info ptm -CC -gt -mrhoist on mygrammar.g
-
-#100a. (Changed in 1.33MR10) Predicate tree simplification
-
- When the same predicates can be referenced in more than one
- alternative of a block large predicate trees can be formed.
-
- The difference that these optimizations make is so dramatic
- that I have decided to use it even when -mrhoist is not selected.
-
- Consider the following grammar:
-
- start : ( all )* ;
-
- all : a
- | d
- | e
- | f
- ;
-
- a : c A B
- | c A C
- ;
-
- c : <<AAA(LATEXT(2))>>?
- ;
-
- d : <<BBB(LATEXT(2))>>? B C
- ;
-
- e : <<CCC(LATEXT(2))>>? B C
- ;
-
- f : e X Y
- ;
-
- In rule "a" there is a reference to rule "c" in both alternatives.
- The length of the predicate AAA is k=2 and it can be followed in
- alternative 1 only by (A B) while in alternative 2 it can be
- followed only by (A C). Thus they do not have identical context.
-
- In rule "all" the alternatives which refer to rules "e" and "f" allow
- elimination of the duplicate reference to predicate CCC.
-
- The table below summarized the kind of simplification performed by
- 1.33MR10. In the table, X and Y stand for single predicates
- (not trees).
-
- (OR X (OR Y (OR Z))) => (OR X Y Z)
- (AND X (AND Y (AND Z))) => (AND X Y Z)
-
- (OR X (... (OR X Y) ... )) => (OR X (... Y ... ))
- (AND X (... (AND X Y) ... )) => (AND X (... Y ... ))
- (OR X (... (AND X Y) ... )) => (OR X (... ... ))
- (AND X (... (OR X Y) ... )) => (AND X (... ... ))
-
- (AND X) => X
- (OR X) => X
-
- In a test with a complex grammar for a real application, a predicate
- tree with six OR nodes and 12 leaves was reduced to "(OR X Y Z)".
-
- In 1.33MR10 there is a greater effort to release memory used
- by predicates once they are no longer in use.
-
-#100b. (Changed in 1.33MR10) Suppression of extra predicate tests
-
- The following optimizations require that -mrhoist be selected.
-
- It is relatively easy to optimize the code generated for predicate
- gates when they are of the form:
-
- (AND X Y Z ...)
- or (OR X Y Z ...)
-
- where X, Y, Z, and "..." represent individual predicates (leaves) not
- predicate trees.
-
- If the predicate is an AND the contexts of the X, Y, Z, etc. are
- ANDed together to create a single Tree context for the group and
- context tests for the individual predicates are suppressed:
-
- --------------------------------------------------
- Note: This was incorrect. The contexts should be
- ORed together. This has been fixed. A more
- complete description is available in item #152.
- ---------------------------------------------------
-
- Optimization 1: (AND X Y Z ...)
-
- Suppose the context for Xtest is LA(1)==LP and the context for
- Ytest is LA(1)==LP && LA(2)==ID.
-
- Without the optimization the code would resemble:
-
- if (lookaheadContext &&
- !(LA(1)==LP && LA(1)==LP && LA(2)==ID) ||
- ( (! LA(1)==LP || Xtest) &&
- (! (LA(1)==LP || LA(2)==ID) || Xtest)
- )) {...
-
- With the -mrhoist optimization the code would resemble:
-
- if (lookaheadContext &&
- ! (LA(1)==LP && LA(2)==ID) || (Xtest && Ytest) {...
-
- Optimization 2: (OR X Y Z ...) with identical contexts
-
- Suppose the context for Xtest is LA(1)==ID and for Ytest
- the context is also LA(1)==ID.
-
- Without the optimization the code would resemble:
-
- if (lookaheadContext &&
- ! (LA(1)==ID || LA(1)==ID) ||
- (LA(1)==ID && Xtest) ||
- (LA(1)==ID && Ytest) {...
-
- With the -mrhoist optimization the code would resemble:
-
- if (lookaheadContext &&
- (! LA(1)==ID) || (Xtest || Ytest) {...
-
- Optimization 3: (OR X Y Z ...) with distinct contexts
-
- Suppose the context for Xtest is LA(1)==ID and for Ytest
- the context is LA(1)==LP.
-
- Without the optimization the code would resemble:
-
- if (lookaheadContext &&
- ! (LA(1)==ID || LA(1)==LP) ||
- (LA(1)==ID && Xtest) ||
- (LA(1)==LP && Ytest) {...
-
- With the -mrhoist optimization the code would resemble:
-
- if (lookaheadContext &&
- (zzpf=0,
- (LA(1)==ID && (zzpf=1) && Xtest) ||
- (LA(1)==LP && (zzpf=1) && Ytest) ||
- !zzpf) {
-
- These may appear to be of similar complexity at first,
- but the non-optimized version contains two tests of each
- context while the optimized version contains only one
- such test, as well as eliminating some of the inverted
- logic (" !(...) || ").
-
- Optimization 4: Computation of predicate gate trees
-
- When generating code for the gates of predicate expressions
- antlr 1.33 vanilla uses a recursive procedure to generate
- "&&" and "||" expressions for testing the lookahead. As each
- layer of the predicate tree is exposed a new set of "&&" and
- "||" expressions on the lookahead are generated. In many
- cases the lookahead being tested has already been tested.
-
- With -mrhoist a lookahead tree is computed for the entire
- lookahead expression. This means that predicates with identical
- context or context which is a subset of another predicate's
- context disappear.
-
- This is especially important for predicates formed by rules
- like the following:
-
- uppperCaseVowel : <<isUpperCase(LATEXT(1))>>? vowel;
- vowel: : <<isVowel(LATEXT(1))>>? LETTERS;
-
- These predicates are combined using AND since both must be
- satisfied for rule upperCaseVowel. They have identical
- context which makes this optimization very effective.
-
- The affect of Items #100a and #100b together can be dramatic. In
- a very large (but real world) grammar one particular predicate
- expression was reduced from an (unreadable) 50 predicate leaves,
- 195 LA(1) terms, and 5500 characters to an (easily comprehensible)
- 3 predicate leaves (all different) and a *single* LA(1) term.
-
-#99. (Changed in 1.33MR10) Code generation for expression trees
-
- Expression trees are used for k>1 grammars and predicates with
- lookahead depth >1. This optimization must be enabled using
- "-mrhoist on". (Clarification added for 1.33MR11).
-
- In the processing of expression trees, antlr can generate long chains
- of token comparisons. Prior to 1.33MR10 there were many redundant
- parenthesis which caused problems for compilers which could handle
- expressions of only limited complexity. For example, to test an
- expression tree (root R A B C D), antlr would generate something
- resembling:
-
- (LA(1)==R && (LA(2)==A || (LA(2)==B || (LA(2)==C || LA(2)==D)))))
-
- If there were twenty tokens to test then there would be twenty
- parenthesis at the end of the expression.
-
- In 1.33MR10 the generated code for tree expressions resembles:
-
- (LA(1)==R && (LA(2)==A || LA(2)==B || LA(2)==C || LA(2)==D))
-
- For "complex" expressions the output is indented to reflect the LA
- number being tested:
-
- (LA(1)==R
- && (LA(2)==A || LA(2)==B || LA(2)==C || LA(2)==D
- || LA(2)==E || LA(2)==F)
- || LA(1)==S
- && (LA(2)==G || LA(2)==H))
-

- Suggested by S. Bochnak (S.Bochnak@@microTool.com.pl),
-
-#98. (Changed in 1.33MR10) Option "-info p"
-
- When the user selects option "-info p" the program will generate
- detailed information about predicates. If the user selects
- "-mrhoist on" additional detail will be provided explaining
- the promotion and suppression of predicates. The output is part
- of the generated file and sandwiched between #if 0/#endif statements.
-
- Consider the following k=1 grammar:
-
- start : ( all ) * ;
-
- all : ( a
- | b
- )
- ;
-
- a : c B
- ;
-
- c : <<LATEXT(1)>>?
- | B
- ;
-
- b : <<LATEXT(1)>>? X
- ;
-
- Below is an excerpt of the output for rule "start" for the three
- predicate options (off, on, and maintenance release style hoisting).
-
- For those who do not wish to use the "-mrhoist on" option for code
- generation the option can be used in a "diagnostic" mode to provide
- valuable information:
-
- a. where one should insert null actions to inhibit hoisting
- b. a chain of rule references which shows where predicates are
- being hoisted

-#97. (Fixed in 1.33MR10) "Predicate applied for more than one ... "
-
- In 1.33 vanilla, the grammar listed below produced this message for
- the first alternative (only) of rule "b":
-
- warning: predicate applied for >1 lookahead 1-sequences
- [you may only want one lookahead 1-sequence to apply.
- Try using a context guard '(...)? =>'
-
- In 1.33MR10 the message is issued for both alternatives.
-
- top : (a)*;
- a : b | c ;
-
- b : <<PPP(LATEXT(1))>>? ( AAA | BBB )
- | <<QQQ(LATEXT(1))>>? ( XXX | YYY )
- ;
-
- c : AAA | XXX;
-
-#96. (Fixed in 1.33MR10) Guard predicates ignored when -prc off
-
- Prior to 1.33MR10, guard predicate code was not generated unless
- "-prc on" was selected.
-
- This was incorrect, since "-prc off" (the default) is supposed to
- disable only AUTOMATIC computation of predicate context, not the
- programmer specified context supplied by guard predicates.
-
-#95. (Fixed in 1.33MR10) Predicate guard context length was k, not max(k,ck)
-
- Prior to 1.33MR10, predicate guards were computed to k tokens rather
- than max(k,ck). Consider the following grammar:
-
- a : ( A B C)? => <<AAA(LATEXT(1))>>? (A|X) (B|Y) (C|Z) ;
-
- The code generated by 1.33 vanilla with "-k 1 -ck 3 -prc on"
- for the predicate in "a" resembles:
-
- if ( (! LA(1)==A) || AAA(LATEXT(1))) {...
-
- With 1.33MR10 and the same options the code resembles:
-
- if ( (! (LA(1)==A && LA(2)==B && LA(3)==C) || AAA(LATEXT(1))) {...
-
-#94. (Fixed in 1.33MR10) Predicates followed by rule references
-
- Prior to 1.33MR10, a semantic predicate which referenced a token
- which was off the end of the rule caused an incomplete context
- to be computed (with "-prc on") for the predicate under some circum-
- stances. In some cases this manifested itself as illegal C code
- (e.g. "LA(2)==[Ep](1)" in the k=2 examples below:
-
- all : ( a ) *;
-
- a : <<AAA(LATEXT(2))>>? ID X
- | <<BBB(LATEXT(2))>>? Y
- | Z
- ;
-
- This might also occur when the semantic predicate was followed
- by a rule reference which was shorter than the length of the
- semantic predicate:
-
- all : ( a ) *;
-
- a : <<AAA(LATEXT(2))>>? ID X
- | <<BBB(LATEXT(2))>>? y
- | Z
- ;
-
- y : Y ;
-
- Depending on circumstance, the resulting context might be too
- generous because it was too short, or too restrictive because
- of missing alternatives.
-
-#93. (Changed in 1.33MR10) Definition of Purify macro
-
- Ofer Ben-Ami (gremlin@cs.huji.ac.il) has supplied a definition
- for the Purify macro:
-
- #define PURIFY(r, s) memset((char *) &(r), '\0', (s));
-
- Note: This may not be the right thing to do for C++ objects that
- have constructors. Reported by Bonny Rais (bonny@werple.net.au).
-
- For those cases one should #define PURIFY to an empty macro in the
- #header or #first actions.
-
-#92. (Fixed in 1.33MR10) Guarded predicates and hoisting
-
- When a guarded predicate participates in hoisting it is linked into
- a predicate expression tree. Prior to 1.33MR10 this link was never
- cleared and the next time the guard was used to construct a new
- tree the link could contain a spurious reference to another element
- which had previosly been joined to it in the semantic predicate tree.
-
- For example:
-
- start : ( all ) *;
- all : ( a | b ) ;
-
- start2 : ( all2 ) *;
- all2 : ( a ) ;
-
- a : (A)? => <<AAA(LATEXT(1))>>? A ;
- b : (B)? => <<BBB(LATEXT(1))>>? B ;
-
- Prior to 1.33MR10 the code for "start2" would include a spurious
- reference to the BBB predicate which was left from constructing
- the predicate tree for rule "start" (i.e. or(AAA,BBB) ).
-
- In 1.33MR10 this problem is avoided by cloning the original guard
- each time it is linked into a predicate tree.
-
-#91. (Changed in 1.33MR10) Extensive changes to semantic pred hoisting

- This has been rendered obsolete by Item #117
- ============================================
-
-#90. (Fixed in 1.33MR10) Semantic pred with LT(i) and i>max(k,ck)
-
- There is a bug in antlr 1.33 vanilla and all maintenance releases
- prior to 1.33MR10 which allows semantic predicates to reference
- an LT(i) or LATEXT(i) where i is larger than max(k,ck). When
- this occurs antlr will attempt to mark the ith element of an array
- in which there are only max(k,ck) elements. The result cannot
- be predicted.
-
- Using LT(i) or LATEXT(i) for i>max(k,ck) is reported as an error
- in 1.33MR10.
-
-#89. Rescinded
-
-#88. (Fixed in 1.33MR10) Tokens used in semantic predicates in guess mode
-
- Consider the behavior of a semantic predicate during guess mode:
-
- rule : a:A (
- <<test($a)>>? b:B
- | c:C
- );
-
- Prior to MR10 the assignment of the token or attribute to
- $a did not occur during guess mode, which would cause the
- semantic predicate to misbehave because $a would be null.
-
- In 1.33MR10 a semantic predicate with a reference to an
- element label (such as $a) forces the assignment to take
- place even in guess mode.
-
- In order to work, this fix REQUIRES use of the $label format
- for token pointers and attributes referenced in semantic
- predicates.
-
- The fix does not apply to semantic predicates using the
- numeric form to refer to attributes (e.g. <<test($1)>>?).
- The user will receive a warning for this case.
-
- Reported by Rob Trout (trout@mcs.cs.kent.edu).
-
-#87. (Fixed in 1.33MR10) Malformed guard predicates
-
- Context guard predicates may contain only references to
- tokens. They may not contain references to (...)+ and
- (...)* blocks. This is now checked. This replaces the
- fatal error message in item #78 with an appropriate
- (non-fatal) error messge.
-
- In theory, context guards should be allowed to reference
- rules. However, I have not had time to fix this.
- Evaluation of the guard takes place before all rules have
- been read, making it difficult to resolve a forward reference
- to rule "zzz" - it hasn't been read yet ! To postpone evaluation
- of the guard until all rules have been read is too much
- for the moment.
-
-#86. (Fixed in 1.33MR10) Unequal set size in set_sub
-
- Routine set_sub() in pccts/support/set/set.h did not work
- correctly when the sets were of unequal sizes. Rewrote
- set_equ to make it simpler and remove unnecessary and
- expensive calls to set_deg(). This routine was not used
- in 1.33 vanila.
-
-#85. (Changed in 1.33MR10) Allow redefinition of MaxNumFiles
-
- Raised the maximum number of input files to 99 from 20.
- Put a #ifndef/#endif around the "#define MaxNumFiles 99".
-
-#84. (Fixed in 1.33MR10) Initialize zzBadTok in macro zzRULE
-
- Initialize zzBadTok to NULL in zzRULE macro of AParser.h.
- in order to get rid of warning messages.
-
-#83. (Fixed in 1.33MR10) False warnings with -w2 for #tokclass
-
- When -w2 is selected antlr gives inappropriate warnings about
- #tokclass names not having any associated regular expressions.
- Since a #tokclass is not a "real" token it will never have an
- associated regular expression and there should be no warning.
-
- Reported by Derek Pappas (derek.pappas@eng.sun.com)
-
-#82. (Fixed in 1.33MR10) Computation of follow sets with multiple cycles
-
- Reinier van den Born (reinier@vnet.ibm.com) reported a problem
- in the computation of follow sets by antlr. The problem (bug)
- exists in 1.33 vanilla and all maintenance releases prior to 1.33MR10.
-
- The problem involves the computation of follow sets when there are
- cycles - rules which have mutual references. I believe the problem
- is restricted to cases where there is more than one cycle AND
- elements of those cycles have rules in common. Even when this
- occurs it may not affect the code generated - but it might. It
- might also lead to undetected ambiguities.
-
- There were no changes in antlr or dlg output from the revised version.
-
- The following fragment demonstates the problem by giving different
- follow sets (option -pa) for var_access when built with k=1 and ck=2 on
- 1.33 vanilla and 1.33MR10:
-
- echo_statement : ECHO ( echo_expr )*
- ;
-
- echo_expr : ( command )?
- | expression
- ;
-
- command : IDENTIFIER
- { concat }
- ;
-
- expression : operand ( OPERATOR operand )*
- ;
-
- operand : value
- | START command END

-#81. (Changed in 1.33MR10) C mode use of attributes and ASTs
-
- Reported by Isaac Clark (irclark@mindspring.com).
-
- C mode code ignores attributes returned by rules which are
- referenced using element labels when ASTs are enabled (-gt option).
-
- 1. start : r:rule t:Token <<$start=$r;>>
-
- The $r refrence will not work when combined with
- the -gt option.
-
- 2. start : t:Token <<$start=$t;>>
-
- The $t reference works in all cases.
-
- 3. start : rule <<$0=$1;>>
-
- Numeric labels work in all cases.
-
- With MR10 the user will receive an error message for case 1 when
- the -gt option is used.
-
-#80. (Fixed in 1.33MR10) (...)? as last alternative of block
-
- A construct like the following:
-
- rule : a
- | (b)?
- ;
-
- does not make sense because there is no alternative when
- the guess block fails. This is now reported as a warning
- to the user.
-
- Previously, there was a code generation error for this case:
- the guess block was not "closed" when the guess failed.
- This could cause an infinite loop or other problems. This
- is now fixed.
-
- Example problem:
-
- #header<<
- #include <stdio.h>
- #include "charptr.h"

-#79. (Changed in 1.33MR10) Use of -fh with multiple parsers
-
- Previously, antlr always used the pre-processor symbol
- STDPCCTS_H as a gate for the file stdpccts.h. This
- caused problems when there were multiple parsers defined
- because they used the same gate symbol.
-
- In 1.33MR10, the -fh filename is used to generate the
- gate file for stdpccts.h. For instance:
-
- antlr -fh std_parser1.h
-
- generates the pre-processor symbol "STDPCCTS_std_parser1_H".

-#78. (Changed in 1.33MR9) Guard predicates that refer to rules
-
- ------------------------
- Please refer to Item #87
- ------------------------
-
- Guard predicates are processed during an early phase
- of antlr (during parsing) before all data structures
- are completed.
-
- There is an apparent bug in earlier versions of 1.33
- which caused guard predicates which contained references
- to rules (rather than tokens) to reference a structure
- which hadn't yet been initialized.
-
- In some cases (perhaps all cases) references to rules
- in guard predicates resulted in the use of "garbage".
-
-#79. (Changed in 1.33MR9) Jeff Vincent (JVincent@novell.com)
-
- Previously, the maximum length file name was set
- arbitrarily to 300 characters in antlr, dlg, and sorcerer.
-
- The config.h file now attempts to define the maximum length
- filename using _MAX_PATH from stdlib.h before falling back
- to using the value 300.
-
-#78. (Changed in 1.33MR9) Jeff Vincent (JVincent@novell.com)
-
- Put #ifndef/#endif around definition of ZZLEXBUFSIZE in
- antlr.
-
-#77. (Changed in 1.33MR9) Arithmetic overflow for very large grammars
-
- In routine HandleAmbiguities() antlr attempts to compute the
- number of possible elements in a set that is order of
- number-of-tokens raised to the number-of-lookahead-tokens power.
- For large grammars or large lookahead (e.g. -ck 7) this can
- cause arithmetic overflow.
-
- With 1.33MR9, arithmetic overflow in this computation is reported
- the first time it happens. The program continues to run and
- the program branches based on the assumption that the computed
- value is larger than any number computed by counting actual cases
- because 2**31 is larger than the number of bits in most computers.
-
- Before 1.33MR9 overflow was not reported. The behavior following
- overflow is not predictable by anyone but the original author.
-
- NOTE
-
- In 1.33MR10 the warning message is suppressed.
- The code which detects the overflow allows the
- computation to continue without an error. The
- error message itself made made users worry.
-
-#76. (Changed in 1.33MR9) Jeff Vincent (JVincent@novell.com)
-
- Jeff Vincent has convinced me to make ANTLRCommonToken and
- ANTLRCommonNoRefCountToken use variable length strings
- allocated from the heap rather than fixed length strings.
- By suitable definition of setText(), the copy constructor,
- and operator =() it is possible to maintain "copy" semantics.
- By "copy" semantics I mean that when a token is copied from
- an existing token it receives its own, distinct, copy of the
- text allocated from the heap rather than simply a pointer
- to the original token's text.
-
- ============================================================
- W * A * R * N * I * N * G

- It is possible that this may cause problems for some users.

-
-#75. (Changed in 1.33MR9) Bruce Guenter (bruceg@qcc.sk.ca)
-
- Make DLGStringInput const correct. Since this is infrequently
- subclassed, it should affect few users, I hope.
-
-#74. (Changed in 1.33MR9) -o (output directory) option
-
- Antlr does not properly handle the -o output directory option
- when the filename of the grammar contains a directory part. For
- example:
-
- antlr -o outdir pccts_src/myfile.g
-
- causes antlr create a file called "outdir/pccts_src/myfile.cpp.
- It SHOULD create outdir/myfile.cpp
-
- The suggested code fix has been installed in antlr, dlg, and
- Sorcerer.

-#65. (Changed in 1.33MR9) PCCTSAST::deepCopy() and ast_dup() bug
-
- Jeff Vincent (JVincent@novell.com) found that deepCopy()
- made new copies of only the direct descendents. No new
- copies were made of sibling nodes, Sibling pointers are
- set to zero by shallowCopy().
-
- PCCTS_AST::deepCopy() has been changed to make a
- deep copy in the traditional sense.
-
- The deepCopy() routine depends on the behavior of
- shallowCopy(). In all sor examples I've found,
- shallowCopy() zeroes the right and down pointers.
-

-
- While comparing deepCopy() for C++ mode with ast_dup for

-
- Reported by S.Bochnak@microTool.com.pl
-
-#61. (Changed in 1.33MR8) Using rule>[i,j] when rule has no return values
-
- Previously, the following code would cause antlr to core when
- it tried to generate code for rule1 because rule2 had no return
- values ("upward inheritance"):
-
- rule1 : <<int i; int j>>
- rule2 > [i,j]
- ;
-
- rule2 : Anything ;
-
- Reported by S.Bochnak@microTool.com.pl
-
- Verified correct operation of antlr MR8 when missing or extra
- inheritance arguments for all combinations. When there are
- missing or extra arguments code will still be generated even
- though this might cause the invocation of a subroutine with
- the wrong number of arguments.
-
-#60. (Changed in 1.33MR7) Major changes to exception handling
-
- There were significant problems in the handling of exceptions
- in 1.33 vanilla. The general problem is that it can only
- process one level of exception handler. For example, a named
- exception handler, an exception handler for an alternative, or
- an exception for a subrule always went to the rule's exception
- handler if there was no "catch" which matched the exception.
-
- In 1.33MR7 the exception handlers properly "nest". If an
- exception handler does not have a matching "catch" then the
- nextmost outer exception handler is checked for an appropriate
- "catch" clause, and so on until an exception handler with an
- appropriate "catch" is found.
-
- There are still undesirable features in the way exception
- handlers are implemented, but I do not have time to fix them
- at the moment:
-
- The exception handlers for alternatives are outside the
- block containing the alternative. This makes it impossible
- to access variables declared in a block or to resume the
- parse by "falling through". The parse can still be easily
- resumed in other ways, but not in the most natural fashion.
-
- This results in an inconsistentcy between named exception
- handlers and exception handlers for alternatives. When
- an exception handler for an alternative "falls through"
- it goes to the nextmost outer handler - not the "normal
- action".
-
- A major difference between 1.33MR7 and 1.33 vanilla is
- the default action after an exception is caught:
-
- 1.33 Vanilla
- ------------
- In 1.33 vanilla the signal value is set to zero ("NoSignal")
- and the code drops through to the code following the exception.
- For named exception handlers this is the "normal action".
- For alternative exception handlers this is the rule's handler.
-
- 1.33MR7
- -------
- In 1.33MR7 the signal value is NOT automatically set to zero.
-
- There are two cases:
-
- For named exception handlers: if the signal value has been
- set to zero the code drops through to the "normal action".
-
- For all other cases the code branches to the nextmost outer
- exception handler until it reaches the handler for the rule.
-
- The following macros have been defined for convenience:
-
- C/C++ Mode Name
- --------------------
- (zz)suppressSignal
- set signal & return signal arg to 0 ("NoSignal")
- (zz)setSignal(intValue)
- set signal & return signal arg to some value
- (zz)exportSignal
- copy the signal value to the return signal arg
-
- I'm not sure why PCCTS make a distinction between the local
- signal value and the return signal argument, but I'm loathe
- to change the code. The burden of copying the local signal
- value to the return signal argument can be given to the
- default signal handler, I suppose.
-
-#59. (Changed in 1.33MR7) Prototypes for some functions
-
- Added prototypes for the following functions to antlr.h
-
- zzconsumeUntil()
- zzconsumeUntilToken()
-
-#58. (Changed in 1.33MR7) Added defintion of zzbufsize to dlgauto.h
-
-#57. (Changed in 1.33MR7) Format of #line directive
-
- Previously, the -gl directive for line 1234 would
- resemble: "# 1234 filename.g". This caused problems
- for some compilers/pre-processors. In MR7 it generates
- "#line 1234 filename.g".
-
-#56. (Added in 1.33MR7) Jan Mikkelsen <janm@zeta.org.au>
-
- Move PURIFY macro invocaton to after rule's init action.
-
-#55. (Fixed in 1.33MR7) Unitialized variables in ANTLRParser
-
- Member variables inf_labase and inf_last were not initialized.
- (See item #50.)
-
-#54. (Fixed in 1.33MR6) Brad Schick (schick@interacess.com)
-
- Previously, the following constructs generated the same
- code:
-
- rule1 : (A B C)?
- | something-else
- ;
-
- rule2 : (A B C)? ()
- | something-else
- ;
-
- In all versions of pccts rule1 guesses (A B C) and then
- consume all three tokens if the guess succeeds. In MR6
- rule2 guesses (A B C) but consumes NONE of the tokens
- when the guess succeeds because "()" matches epsilon.
-
-#53. (Explanation for 1.33MR6) What happens after an exception is caught ?
-
- The Book is silent about what happens after an exception
- is caught.
-
- The following code fragment prints "Error Action" followed
- by "Normal Action".
-
- test : Word ex:Number <<printf("Normal Action\n");>>
- exception[ex]
- catch NoViableAlt:
- <<printf("Error Action\n");>>
- ;
-
- The reason for "Normal Action" is that the normal flow of the
- program after a user-written exception handler is to "drop through".
- In the case of an exception handler for a rule this results in
- the exection of a "return" statement. In the case of an
- exception handler attached to an alternative, rule, or token
- this is the code that would have executed had there been no
- exception.
-
- The user can achieve the desired result by using a "return"
- statement.
-
- test : Word ex:Number <<printf("Normal Action\n");>>
- exception[ex]
- catch NoViableAlt:
- <<printf("Error Action\n"); return;>>
- ;
-
- The most powerful mechanism for recovery from parse errors
- in pccts is syntactic predicates because they provide
- backtracking. Exceptions allow "return", "break",
- "consumeUntil(...)", "goto _handler", "goto _fail", and
- changing the _signal value.
-
-#52. (Fixed in 1.33MR6) Exceptions without syntactic predicates
-
- The following generates bad code in 1.33 if no syntactic
- predicates are present in the grammar.
-
- test : Word ex:Number <<printf("Normal Action\n");>>
- exception[ex]
- catch NoViableAlt:
- <<printf("Error Action\n");>>
-
- There is a reference to a guess variable. In C mode
- this causes a compiler error. In C++ mode it generates
- an extraneous check on member "guessing".
-
- In MR6 correct code is generated for both C and C++ mode.
-
-#51. (Added to 1.33MR6) Exception operator "@" used without exceptions
-
- In MR6 added a warning when the exception operator "@" is
- used and no exception group is defined. This is probably
- a case where "\@" or "@" is meant.
-
-#50. (Fixed in 1.33MR6) Gunnar Rxnning (gunnar@candleweb.no)
- http://www.candleweb.no/~gunnar/
-
- Routines zzsave_antlr_state and zzrestore_antlr_state don't
- save and restore all the data needed when switching states.
-
- Suggested patch applied to antlr.h and err.h for MR6.
-
-#49. (Fixed in 1.33MR6) Sinan Karasu (sinan@boeing.com)
-
- Generated code failed to turn off guess mode when leaving a
- (...)+ block which contained a guess block. The result was
- an infinite loop. For example:
-
- rule : (
- (x)?
- | y
- )+
-
- Suggested code fix implemented in MR6. Replaced
-
- ... else if (zzcnt>1) break;
-
- with:
-
- C++ mode:
- ... else if (zzcnt>1) {if (!zzrv) zzGUESS_DONE; break;};
- C mode:
- ... else if (zzcnt>1) {if (zzguessing) zzGUESS_DONE; break;};
-
-#48. (Fixed in 1.33MR6) Invalid exception element causes core
-
- A label attached to an invalid construct can cause
- pccts to crash while processing the exception associated
- with the label. For example:
-
- rule : t:(B C)
- exception[t] catch MismatchedToken: <<printf(...);>>
-
- Version MR6 generates the message:
-
- reference in exception handler to undefined label 't'
-
-#47. (Fixed in 1.33MR6) Manuel Ornato
-
- Under some circumstances involving a k >1 or ck >1
- grammar and a loop block (i.e. (...)* ) pccts will
- fail to detect a syntax error and loop indefinitely.
- The problem did not exist in 1.20, but has existed
- from 1.23 to the present.
-
- Fixed in MR6.

-#35. (Fixed in 1.33MR2) Andreas Magnusson
-(Andreas.Magnusson@mailbox.swipnet.se)
-
- Repair bug introduced by 1.33MR1 for #tokdefs. The original fix
- placed "DLGmaxToken=9999" and "DLGminToken=0" in the TokenType enum
- in order to fix a problem with an aggresive compiler assigning an 8
- bit enum which might be too narrow. This caused #tokdefs to assume
- that there were 9999 real tokens. The repair to the fix causes antlr to
- ignore TokenTypes "DLGmaxToken" and "DLGminToken" in a #tokdefs file.
-
-#34. (Added to 1.33MR1) Add public DLGLexerBase::set_line(int newValue)

-
-#31. (Added to 1.33MR1) Pointer to parser in ANTLRTokenBuffer
- Pointer to parser in DLGLexerBase
-
- The ANTLRTokenBuffer class now contains a pointer to the
- parser which is using it. This is established by the
- ANTLRParser constructor calling ANTLRTokenBuffer::
- setParser(ANTLRParser *p).
-
- When ANTLRTokenBuffer::setParser(ANTLRParser *p) is
- called it saves the pointer to the parser and then
- calls ANTLRTokenStream::setParser(ANTLRParser *p)
- so that the lexer can also save a pointer to the
- parser.
-
- There is also a function getParser() in each class
- with the obvious purpose.
-
- It is possible that these functions will return NULL
- under some circumstances (e.g. a non-DLG lexer is used).
-
-#30. (Added to 1.33MR1) function tokenName(int token) standard
-
- The generated parser class now includes the
- function:
-
- static const ANTLRChar * tokenName(int token)
-
- which returns a pointer to the "name" corresponding
- to the token.
-
- The base class (ANTLRParser) always includes the
- member function:
-
- const ANTLRChar * parserTokenName(int token)
-
- which can be accessed by objects which have a pointer
- to an ANTLRParser, but do not know the name of the
- parser class (e.g. ANTLRTokenBuffer and DLGLexerBase).
-
-#29. (Added to 1.33MR1) Debugging DLG lexers
-
- If the pre-processor symbol DEBUG_LEXER is defined
- then DLexerBase will include code for printing out
- key information about tokens which are recognized.
-
- The debug feature of the lexer is controlled by:
-
- int previousDebugValue=lexer.debugLexer(newValue);
-
- a value of 0 disables output
- a value of 1 enables output
-
- Even if the lexer debug code is compiled into DLexerBase
- it must be enabled before any output is generated. For
- example:
-
- DLGFileInput in(stdin);
- MyDLG lexer(&in,2000);
-
- lexer.setToken(&aToken);
-
- #if DEBUG_LEXER
- lexer.debugLexer(1); // enable debug information
- #endif
-
-#28. (Added to 1.33MR1) More control over DLG header
-
- Version 1.33MR1 adds the following directives to PCCTS
- for C++ mode:
-
- #lexprefix <<source code>>
-
- Adds source code to the DLGLexer.h file
- after the #include "DLexerBase.h" but
- before the start of the class definition.
-
- #lexmember <<source code>>
-
- Adds source code to the DLGLexer.h file
- as part of the DLGLexer class body. It
- appears immediately after the start of
- the class and a "public: statement.
-
-#27. (Fixed in 1.33MR1) Comments in DLG actions
-
- Previously, DLG would not recognize comments as a special case.
- Thus, ">>" in the comments would cause errors. This is fixed.
-
-#26. (Fixed in 1.33MR1) Removed static variables from error routines
-
- Previously, the existence of statically allocated variables
- in some of the parser's member functions posed a danger when
- there was more than one parser active.
-
- Replaced with dynamically allocated/freed variables in 1.33MR1.
-
-#25. (Fixed in 1.33MR1) Use of string literals in semantic predicates
-
- Previously, it was not possible to place a string literal in
- a semantic predicate because it was not properly "stringized"
- for the report of a failed predicate.
-
-#24. (Fixed in 1.33MR1) Continuation lines for semantic predicates
-
- Previously, it was not possible to continue semantic
- predicates across a line because it was not properly
- "stringized" for the report of a failed predicate.
-
- rule : <<ifXYZ()>>?[ a very
- long statement ]
-
-#23. (Fixed in 1.33MR1) {...} envelope for failed semantic predicates
-
- Previously, there was a code generation error for failed
- semantic predicates:
-
- rule : <<xyz()>>?[ stmt1; stmt2; ]
-
- which generated code which resembled:
-
- if (! xyz()) stmt1; stmt2;
-
- It now puts the statements in a {...} envelope:
-
- if (! xyz()) { stmt1; stmt2; };
-
-#22. (Fixed in 1.33MR1) Continuation of #token across lines using "\"
-
- Previously, it was not possible to continue a #token regular
- expression across a line. The trailing "\" and newline caused
- a newline to be inserted into the regular expression by DLG.
-
- Fixed in 1.33MR1.
-
-#21. (Fixed in 1.33MR1) Use of ">>" (right shift operator in DLG actions
-
- It is now possible to use the C++ right shift operator ">>"
- in DLG actions by using the normal escapes:
-
- #token "shift-right" << value=value \>\> 1;>>
-
-#20. (Version 1.33/19-Jan-97 Karl Eccleson <karle@microrobotics.co.uk>
- P.A. Keller (P.A.Keller@bath.ac.uk)
-
- There is a problem due to using exceptions with the -gh option.
-
- Suggested fix now in 1.33MR1.
-
-#19. (Fixed in 1.33MR1) Tom Piscotti and John Lilley
-
- There were problems suppressing messages to stdin and stdout
- when running in a window environment because some functions
- which uses fprint were not virtual.
-
- Suggested change now in 1.33MR1.
-
- I believe all functions containing error messages (excluding those
- indicating internal inconsistency) have been placed in functions
- which are virtual.
-
-#18. (Version 1.33/ 22-Nov-96) John Bair (jbair@iftime.com)
-
- Under some combination of options a required "return _retv" is
- not generated.
-
- Suggested fix now in 1.33MR1.
-
-#17. (Version 1.33/3-Sep-96) Ron House (house@helios.usq.edu.au)
-
- The routine ASTBase::predorder_action omits two "tree->"
- prefixes, which results in the preorder_action belonging
- to the wrong node to be invoked.
-
- Suggested fix now in 1.33MR1.
-
-#16. (Version 1.33/7-Jun-96) Eli Sternheim <eli@interhdl.com>
-
- Routine consumeUntilToken() does not check for end-of-file

-
- Suggested fix now in 1.33MR1.
-
-#15. (Version 1.33/8 Apr 96) Asgeir Olafsson <olafsson@cstar.ac.com>
-
- Problem with tree duplication of doubly linked ASTs in ASTBase.cpp.
-
- Suggested fix now in 1.33MR1.
-
-#14. (Version 1.33/28-Feb-96) Andreas.Magnusson@mailbox.swipnet.se

-#13. (Version 1.33/13-Feb-96) Franklin Chen (chen@adi.com)
-
- Sun C++ Compiler 3.0.1 can't compile testcpp/1 due to goto in
- block with destructors.
-
- Apparently fixed. Can't locate "goto".
-
-#12. (Version 1.33/10-Nov-95) Minor problems with 1.33 code
-
- The following items have been fixed in 1.33MR1:
-
- 1. pccts/antlr/main.c line 142
-
- "void" appears in classic C code
-
- 2. no makefile in support/genmk
-
- 3. EXIT_FAILURE/_SUCCESS instead of PCCTS_EXIT_FAILURE/_SUCCESS
-
- pccts/h/PCCTSAST.cpp
- pccts/h/DLexerBase.cpp
- pccts/testcpp/6/test.g
-
- 4. use of "signed int" isn't accepted by AT&T cfront
-
- pccts/h/PCCTSAST.h line 42
-
- 5. in call to ANTLRParser::FAIL the var arg err_k is passed as
- "int" but is declared "unsigned int".
-
- 6. I believe that a failed validation predicate still does not
- get put in a "{...}" envelope, despite the release notes.
-
- 7. The #token ">>" appearing in the DLG grammar description
- causes DLG to generate the string literal "\>\>" which
- is non-conforming and will cause some compilers to
- complain (scan.c function act10 line 143 of source code).
-
-#11. (Version 1.32b6) Dave Kuhlman (dkuhlman@netcom.com)
-
- Problem with file close in gen.c. Already fixed in 1.33.
-
-#10. (Version 1.32b6/29-Aug-95)
-
- pccts/antlr/main.c contains a C++ style comments on lines 149
- and 176 which causes problems for most C compilers.
-
- Already fixed in 1.33.
-
-#9. (Version 1.32b4/14-Mar-95) dlgauto.h #include "config.h"
-
- The file pccts/h/dlgauto.h should probably contain a #include
- "config.h" as it uses the #define symbol __USE_PROTOS.
-
- Added to 1.33MR1.
-
-#8. (Version 1.32b4/6-Mar-95) Michael T. Richter (mtr@igs.net)
-
- In C++ output mode anonymous tokens from in-line regular expressions
- can create enum values which are too wide for the datatype of the enum
- assigned by the C++ compiler.
-
- Fixed in 1.33MR1.
-
-#7. (Version 1.32b4/6-Mar-95) C++ does not imply __STDC__
-
- In err.h the combination of # directives assumes that a C++
- compiler has __STDC__ defined. This is not necessarily true.
-
- This problem also appears in the use of __USE_PROTOS which
- is appropriate for both Standard C and C++ in antlr/gen.c
- and antlr/lex.c
-
- Fixed in 1.33MR1.
-
-#6. (Version 1.32 ?/15-Feb-95) Name conflict for "TokenType"
-
- Already fixed in 1.33.
-
-#5. (23-Jan-95) Douglas_Cuthbertson.JTIDS@jtids_qmail.hanscom.af.mil
-
- The fail action following a semantic predicate is not enclosed in
- "{...}". This can lead to problems when the fail action contains
- more than one statement.
-
- Fixed in 1.33MR1.
-
-#4 . (Version 1.33/31-Mar-96) jlilley@empathy.com (John Lilley)
-
- Put briefly, a semantic predicate ought to abort a guess if it fails.
-
- Correction suggested by J. Lilley has been added to 1.33MR1.
-
-#3 . (Version 1.33) P.A.Keller@bath.ac.uk
-
- Extra commas are placed in the K&R style argument list for rules
- when using both exceptions and ASTs.
-
- Fixed in 1.33MR1.
-
-#2. (Version 1.32b6/2-Oct-95) Brad Schick <schick@interaccess.com>
-
- Construct #[] generates zzastnew() in C++ mode.
-
- Already fixed in 1.33.
-
-#1. (Version 1.33) Bob Bailey (robert@oakhill.sps.mot.com)
-
- Previously, config.h assumed that all PC systems required
- "short" file names. The user can now override that
- assumption with "#define LONGFILENAMES".
-
- Added to 1.33MR1.

-#258. You can specify a user-defined base class for your parser
-
- The base class must constructor must have a signature similar to
- that of ANTLRParser.
-
-#253. Generation of block preamble (-preamble and -preamble_first)
-
- The antlr option -preamble causes antlr to insert the code
- BLOCK_PREAMBLE at the start of each rule and block.
-
- The antlr option -preamble_first is similar, but inserts the
- code BLOCK_PREAMBLE_FIRST(PreambleFirst_123) where the symbol
- PreambleFirst_123 is equivalent to the first set defined by
- the #FirstSetSymbol described in Item #248.
-
-#248. Generate symbol for first set of an alternative
-
- rr : #FirstSetSymbol(rr_FirstSet) ( Foo | Bar ) ;
-
-#216. Defer token fetch for C++ mode
-
- When the ANTLRParser class is built with the pre-processor option
- ZZDEFER_FETCH defined, the fetch of new tokens by consume() is deferred
- until LA(i) or LT(i) is called.
-
-#215. Use reset() to reset DLGLexerBase
-#188. Added pccts/h/DLG_stream_input.h
-#180. Added ANTLRParser::getEofToken()
-#173. -glms for Microsoft style filenames with -gl
-#170. Suppression for predicates with lookahead depth >1
-
- Consider the following grammar with -ck 2 and the predicate in rule
- "a" with depth 2:
-
- r1 : (ab)* "@"
- ;
-
- ab : a
- | b
- ;
-
- a : (A B)? => <<p(LATEXT(2))>>? A B C
- ;
-
- b : A B C
- ;
-
- Normally, the predicate would be hoisted into rule r1 in order to
- determine whether to call rule "ab". However it should *not* be
- hoisted because, even if p is false, there is a valid alternative
- in rule b. With "-mrhoistk on" the predicate will be suppressed.
-
- If "-info p" command line option is present the following information
- will appear in the generated code:
-
- while ( (LA(1)==A)
- #if 0
-
- Part (or all) of predicate with depth > 1 suppressed by alternative
- without predicate
-
- pred << p(LATEXT(2))>>?
- depth=k=2 ("=>" guard) rule a line 8 t1.g
- tree context:
- (root = A
- B
- )
-
- The token sequence which is suppressed: ( A B )
- The sequence of references which generate that sequence of tokens:
-
- 1 to ab r1/1 line 1 t1.g
- 2 ab ab/1 line 4 t1.g
- 3 to b ab/2 line 5 t1.g
- 4 b b/1 line 11 t1.g
- 5 #token A b/1 line 11 t1.g
- 6 #token B b/1 line 11 t1.g
-
- #endif
-
- A slightly more complicated example:
-
- r1 : (ab)* "@"
- ;
-
- ab : a
- | b
- ;
-
- a : (A B)? => <<p(LATEXT(2))>>? (A B | D E)
- ;
-
- b : <<q(LATEXT(2))>>? D E
- ;
-
-
- In this case, the sequence (D E) in rule "a" which lies behind
- the guard is used to suppress the predicate with context (D E)
- in rule b.
-
- while ( (LA(1)==A || LA(1)==D)
- #if 0
-
- Part (or all) of predicate with depth > 1 suppressed by alternative
- without predicate
-
- pred << q(LATEXT(2))>>?
- depth=k=2 rule b line 11 t2.g
- tree context:
- (root = D
- E
- )
-
- The token sequence which is suppressed: ( D E )
- The sequence of references which generate that sequence of tokens:
-
- 1 to ab r1/1 line 1 t2.g
- 2 ab ab/1 line 4 t2.g
- 3 to a ab/1 line 4 t2.g
- 4 a a/1 line 8 t2.g
- 5 #token D a/1 line 8 t2.g
- 6 #token E a/1 line 8 t2.g
-
- #endif
- &&
- #if 0
-
- pred << p(LATEXT(2))>>?
- depth=k=2 ("=>" guard) rule a line 8 t2.g
- tree context:
- (root = A
- B
- )
-
- #endif
-
- (! ( LA(1)==A && LA(2)==B ) || p(LATEXT(2)) ) {
- ab();
- ...
-
-#165. (Changed in MR13) option -newAST
-
- To create ASTs from an ANTLRTokenPtr antlr usually calls
- "new AST(ANTLRTokenPtr)". This option generates a call
- to "newAST(ANTLRTokenPtr)" instead. This allows a user
- to define a parser member function to create an AST object.
-
-#161. (Changed in MR13) Switch -gxt inhibits generation of tokens.h
-
-#158. (Changed in MR13) #header causes problem for pre-processors
-
- A user who runs the C pre-processor on antlr source suggested
- that another syntax be allowed. With MR13 such directives
- such as #header, #pragma, etc. may be written as "\#header",
- "\#pragma", etc. For escaping pre-processor directives inside
- a #header use something like the following:
-
- \#header
- <<
- \#include <stdio.h>
- >>
-
-#155. (Changed in MR13) Context behind predicates can suppress
-
- With -mrhoist enabled the context behind a guarded predicate can
- be used to suppress other predicates. Consider the following grammar:
-
- r0 : (r1)+;
-
- r1 : rp
- | rq
- ;
- rp : <<p LATEXT(1)>>? B ;
- rq : (A)? => <<q LATEXT(1)>>? (A|B);
-
- In earlier versions both predicates "p" and "q" would be hoisted into
- rule r0. With MR12c predicate p is suppressed because the context which
- follows predicate q includes "B" which can "cover" predicate "p". In
- other words, in trying to decide in r0 whether to call r1, it doesn't
- really matter whether p is false or true because, either way, there is
- a valid choice within r1.
-
-#154. (Changed in MR13) Making hoist suppression explicit using <<nohoist>>
-
- A common error, even among experienced pccts users, is to code
- an init-action to inhibit hoisting rather than a leading action.
- An init-action does not inhibit hoisting.
-
- This was coded:
-
- rule1 : <<;>> rule2
-
- This is what was meant:
-
- rule1 : <<;>> <<;>> rule2
-
- With MR13, the user can code:
-
- rule1 : <<;>> <<nohoist>> rule2
-
- The following will give an error message:
-
- rule1 : <<nohoist>> rule2
-
- If the <<nohoist>> appears as an init-action rather than a leading
- action an error message is issued. The meaning of an init-action
- containing "nohoist" is unclear: does it apply to just one
- alternative or to all alternatives ?
-
-#151a. Addition of ANTLRParser::getLexer(), ANTLRTokenStream::getLexer()
-
- You must manually cast the ANTLRTokenStream to your program's
- lexer class. Because the name of the lexer's class is not fixed.
- Thus it is impossible to incorporate it into the DLGLexerBase
- class.
-
-#151b.(Changed in MR12) ParserBlackBox member getLexer()
-
-#150. (Changed in MR12) syntaxErrCount and lexErrCount now public
-
-#149. (Changed in MR12) antlr option -info o (letter o for orphan)
-
- If there is more than one rule which is not referenced by any
- other rule then all such rules are listed. This is useful for
- alerting one to rules which are not used, but which can still
- contribute to ambiguity.
-
-#148. (Changed in MR11) #token names appearing in zztokens,token_tbl
-
- One can write:
-
- #token Plus ("+") "\+"
- #token RP ("(") "\("
- #token COM ("comment begin") "/\*"
-
- The string in parenthesis will be used in syntax error messages.
-
-#146. (Changed in MR11) Option -treport for locating "difficult" alts
-
- It can be difficult to determine which alternatives are causing
- pccts to work hard to resolve an ambiguity. In some cases the
- ambiguity is successfully resolved after much CPU time so there
- is no message at all.
-
- A rough measure of the amount of work being peformed which is
- independent of the CPU speed and system load is the number of
- tnodes created. Using "-info t" gives information about the
- total number of tnodes created and the peak number of tnodes.
-
- Tree Nodes: peak 1300k created 1416k lost 0
-
- It also puts in the generated C or C++ file the number of tnodes
- created for a rule (at the end of the rule). However this
- information is not sufficient to locate the alternatives within
- a rule which are causing the creation of tnodes.
-
- Using:
-
- antlr -treport 100000 ....
-
- causes antlr to list on stdout any alternatives which require the
- creation of more than 100,000 tnodes, along with the lookahead sets
- for those alternatives.
-
- The following is a trivial case from the ansi.g grammar which shows
- the format of the report. This report might be of more interest
- in cases where 1,000,000 tuples were created to resolve the ambiguity.
-
- -------------------------------------------------------------------------
- There were 0 tuples whose ambiguity could not be resolved
- by full lookahead
- There were 157 tnodes created to resolve ambiguity between:
-
- Choice 1: statement/2 line 475 file ansi.g
- Choice 2: statement/3 line 476 file ansi.g
-
- Intersection of lookahead[1] sets:
-
- IDENTIFIER
-
- Intersection of lookahead[2] sets:
-
- LPARENTHESIS COLON AMPERSAND MINUS
- STAR PLUSPLUS MINUSMINUS ONESCOMPLEMENT
- NOT SIZEOF OCTALINT DECIMALINT
- HEXADECIMALINT FLOATONE FLOATTWO IDENTIFIER
- STRING CHARACTER

-
-#143. (Changed in MR11) Optional ";" at end of #token statement
-
- Fixes problem of:
-
- #token X "x"
-
- <<
- parser action
- >>
-
- Being confused with:
-
- #token X "x" <<lexical action>>
-
-#142. (Changed in MR11) class BufFileInput subclass of DLGInputStream
-
- Alexey Demakov (demakov@kazbek.ispras.ru) has supplied class
- BufFileInput derived from DLGInputStream which provides a
- function lookahead(char *string) to test characters in the
- input stream more than one character ahead.
- The class is located in pccts/h/BufFileInput.* of the kit.
-
-#140. #pred to define predicates
-
- +---------------------------------------------------+
- | Note: Assume "-prc on" for this entire discussion |
- +---------------------------------------------------+
-
- A problem with predicates is that each one is regarded as
- unique and capable of disambiguating cases where two
- alternatives have identical lookahead. For example:
-
- rule : <<pred(LATEXT(1))>>? A
- | <<pred(LATEXT(1))>>? A
- ;
-
- will not cause any error messages or warnings to be issued
- by earlier versions of pccts. To compare the text of the
- predicates is an incomplete solution.
-
- In 1.33MR11 I am introducing the #pred statement in order to
- solve some problems with predicates. The #pred statement allows
- one to give a symbolic name to a "predicate literal" or a
- "predicate expression" in order to refer to it in other predicate
- expressions or in the rules of the grammar.
-
- The predicate literal associated with a predicate symbol is C
- or C++ code which can be used to test the condition. A
- predicate expression defines a predicate symbol in terms of other
- predicate symbols using "!", "&&", and "||". A predicate symbol
- can be defined in terms of a predicate literal, a predicate
- expression, or *both*.
-
- When a predicate symbol is defined with both a predicate literal
- and a predicate expression, the predicate literal is used to generate
- code, but the predicate expression is used to check for two
- alternatives with identical predicates in both alternatives.
-
- Here are some examples of #pred statements:
-
- #pred IsLabel <<isLabel(LATEXT(1))>>?
- #pred IsLocalVar <<isLocalVar(LATEXT(1))>>?
- #pred IsGlobalVar <<isGlobalVar(LATEXT(1)>>?
- #pred IsVar <<isVar(LATEXT(1))>>? IsLocalVar || IsGlobalVar
- #pred IsScoped <<isScoped(LATEXT(1))>>? IsLabel || IsLocalVar
-
- I hope that the use of EBNF notation to describe the syntax of the
- #pred statement will not cause problems for my readers (joke).
-
- predStatement : "#pred"
- CapitalizedName
- (
- "<<predicate_literal>>?"
- | "<<predicate_literal>>?" predOrExpr
- | predOrExpr
- )
- ;
-
- predOrExpr : predAndExpr ( "||" predAndExpr ) * ;
-
- predAndExpr : predPrimary ( "&&" predPrimary ) * ;
-
- predPrimary : CapitalizedName
- | "!" predPrimary
- | "(" predOrExpr ")"
- ;
-
- What is the purpose of this nonsense ?
-
- To understand how predicate symbols help, you need to realize that
- predicate symbols are used in two different ways with two different
- goals.
-
- a. Allow simplification of predicates which have been combined
- during predicate hoisting.
-
- b. Allow recognition of identical predicates which can't disambiguate
- alternatives with common lookahead.
-
- First we will discuss goal (a). Consider the following rule:
-
- rule0: rule1
- | ID
- | ...
- ;
-
- rule1: rule2
- | rule3
- ;
-
- rule2: <<isX(LATEXT(1))>>? ID ;
- rule3: <<!isX(LATEXT(1)>>? ID ;
-
- When the predicates in rule2 and rule3 are combined by hoisting
- to create a prediction expression for rule1 the result is:
-
- if ( LA(1)==ID
- && ( isX(LATEXT(1) || !isX(LATEXT(1) ) ) { rule1(); ...
-
- This is inefficient, but more importantly, can lead to false
- assumptions that the predicate expression distinguishes the rule1
- alternative with some other alternative with lookahead ID. In
- MR11 one can write:
-
- #pred IsX <<isX(LATEXT(1))>>?
-
- ...
-
- rule2: <<IsX>>? ID ;
- rule3: <<!IsX>>? ID ;
-
- During hoisting MR11 recognizes this as a special case and
- eliminates the predicates. The result is a prediction
- expression like the following:
-
- if ( LA(1)==ID ) { rule1(); ...
-
- Please note that the following cases which appear to be equivalent
- *cannot* be simplified by MR11 during hoisting because the hoisting
- logic only checks for a "!" in the predicate action, not in the
- predicate expression for a predicate symbol.
-
- *Not* equivalent and is not simplified during hoisting:
-
- #pred IsX <<isX(LATEXT(1))>>?
- #pred NotX <<!isX(LATEXT(1))>>?
- ...
- rule2: <<IsX>>? ID ;
- rule3: <<NotX>>? ID ;
-
- *Not* equivalent and is not simplified during hoisting:
-
- #pred IsX <<isX(LATEXT(1))>>?
- #pred NotX !IsX
- ...
- rule2: <<IsX>>? ID ;
- rule3: <<NotX>>? ID ;
-
- Now we will discuss goal (b).
-
- When antlr discovers that there is a lookahead ambiguity between
- two alternatives it attempts to resolve the ambiguity by searching
- for predicates in both alternatives. In the past any predicate
- would do, even if the same one appeared in both alternatives:
-
- rule: <<p(LATEXT(1))>>? X
- | <<p(LATEXT(1))>>? X
- ;
-
- The #pred statement is a start towards solving this problem.
- During ambiguity resolution (*not* predicate hoisting) the
- predicates for the two alternatives are expanded and compared.
- Consider the following example:
-
- #pred Upper <<isUpper(LATEXT(1))>>?
- #pred Lower <<isLower(LATEXT(1))>>?
- #pred Alpha <<isAlpha(LATEXT(1))>>? Upper || Lower
-
- rule0: rule1
- | <<Alpha>>? ID
- ;
-
- rule1:
- | rule2
- | rule3
- ...
- ;
-
- rule2: <<Upper>>? ID;
- rule3: <<Lower>>? ID;
-
- The definition of #pred Alpha expresses:
-
- a. to test the predicate use the C code "isAlpha(LATEXT(1))"
-
- b. to analyze the predicate use the information that
- Alpha is equivalent to the union of Upper and Lower,
-
- During ambiguity resolution the definition of Alpha is expanded
- into "Upper || Lower" and compared with the predicate in the other
- alternative, which is also "Upper || Lower". Because they are
- identical MR11 will report a problem.

-
- The comparison of the predicates for the two alternatives takes
- place without context information, which means that in some cases
- the predicates will be considered identical even though they operate
- on disjoint lookahead sets. Consider:
-
- #pred Alpha
-
- rule1: <<Alpha>>? ID
- | <<Alpha>>? Label
- ;
-
- Because the comparison of predicates takes place without context
- these will be considered identical. The reason for comparing
- without context is that otherwise it would be necessary to re-evaluate
- the entire predicate expression for each possible lookahead sequence.
- This would require more code to be written and more CPU time during
- grammar analysis, and it is not yet clear whether anyone will even make
- use of the new #pred facility.
-
- A temporary workaround might be to use different #pred statements
- for predicates you know have different context. This would avoid
- extraneous warnings.
-
- The above example might be termed a "false positive". Comparison
- without context will also lead to "false negatives". Consider the
- following example:
-
- #pred Alpha
- #pred Beta
-
- rule1: <<Alpha>>? A
- | rule2
- ;
-
- rule2: <<Alpha>>? A
- | <<Beta>>? B
- ;
-
- The predicate used for alt 2 of rule1 is (Alpha || Beta). This
- appears to be different than the predicate Alpha used for alt1.
- However, the context of Beta is B. Thus when the lookahead is A
- Beta will have no resolving power and Alpha will be used for both
- alternatives. Using the same predicate for both alternatives isn't
- very helpful, but this will not be detected with 1.33MR11.
-
- To properly handle this the predicate expression would have to be
- evaluated for each distinct lookahead context.
-
- To determine whether two predicate expressions are identical is
- difficult. The routine may fail to identify identical predicates.
-
- The #pred feature also compares predicates to see if a choice between
- alternatives which is resolved by a predicate which makes the second
- choice unreachable. Consider the following example:
-
- #pred A <<A(LATEXT(1)>>?
- #pred B <<B(LATEXT(1)>>?
- #pred A_or_B A || B
-
- r : s
- | t
- ;
- s : <<A_or_B>>? ID
- ;
- t : <<A>>? ID
- ;

-#132. (Changed in 1.33MR11) Recognition of identical predicates in alts
-
- Prior to 1.33MR11, there would be no ambiguity warning when the
- very same predicate was used to disambiguate both alternatives:
-
- test: ref B
- | ref C
- ;
-
- ref : <<pred(LATEXT(1)>>? A
-
- In 1.33MR11 this will cause the warning:
-
- warning: the predicates used to disambiguate rule test
- (file v98.g alt 1 line 1 and alt 2 line 2)
- are identical and have no resolving power
-
- ----------------- Note -----------------
-
- This is different than the following case
-
- test: <<pred(LATEXT(1))>>? A B
- | <<pred(LATEXT(1)>>? A C
- ;
-
- In this case there are two distinct predicates
- which have exactly the same text. In the first
- example there are two references to the same
- predicate. The problem represented by this
- grammar will be addressed later.

-#124. A Note on the New "&&" Style Guarded Predicates
-
- I've been asked several times, "What is the difference between
- the old "=>" style guard predicates and the new style "&&" guard
- predicates, and how do you choose one over the other" ?
-
- The main difference is that the "=>" does not apply the
- predicate if the context guard doesn't match, whereas
- the && form always does. What is the significance ?
-
- If you have a predicate which is not on the "leading edge"
- it is cannot be hoisted. Suppose you need a predicate that
- looks at LA(2). You must introduce it manually. The
- classic example is:
-
- castExpr :
- LP typeName RP
- | ....
- ;
-
- typeName : <<isTypeName(LATEXT(1))>>? ID
- | STRUCT ID
- ;
-
- The problem is that isTypeName() isn't on the leading edge
- of typeName, so it won't be hoisted into castExpr to help
- make a decision on which production to choose.
-
- The *first* attempt to fix it is this:
-
- castExpr :
- <<isTypeName(LATEXT(2))>>?
- LP typeName RP
- | ....
- ;
-
- Unfortunately, this won't work because it ignores
- the problem of STRUCT. The solution is to apply
- isTypeName() in castExpr if LA(2) is an ID and
- don't apply it when LA(2) is STRUCT:
-
- castExpr :
- (LP ID)? => <<isTypeName(LATEXT(2))>>?
- LP typeName RP
- | ....
- ;
-
- In conclusion, the "=>" style guarded predicate is
- useful when:
-
- a. the tokens required for the predicate
- are not on the leading edge
- b. there are alternatives in the expression
- selected by the predicate for which the
- predicate is inappropriate
-
- If (b) were false, then one could use a simple
- predicate (assuming "-prc on"):
-
- castExpr :
- <<isTypeName(LATEXT(2))>>?
- LP typeName RP
- | ....
- ;
-
- typeName : <<isTypeName(LATEXT(1))>>? ID
- ;
-
- So, when do you use the "&&" style guarded predicate ?
-
- The new-style "&&" predicate should always be used with
- predicate context. The context guard is in ADDITION to
- the automatically computed context. Thus it useful for
- predicates which depend on the token type for reasons
- other than context.
-
- The following example is contributed by Reinier van den Born
- (reinier@vnet.ibm.com).
-
- +-------------------------------------------------------------------------+
- | This grammar has two ways to call functions: |
- | |
- | - a "standard" call syntax with parens and comma separated args |
- | - a shell command like syntax (no parens and spacing separated args) |
- | |
- | The former also allows a variable to hold the name of the function, |
- | the latter can also be used to call external commands. |
- | |
- | The grammar (simplified) looks like this: |
- | |
- | fun_call : ID "(" { expr ("," expr)* } ")" |
- | /* ID is function name */ |
- | | "@" ID "(" { expr ("," expr)* } ")" |
- | /* ID is var containing fun name */ |
- | ; |
- | |
- | command : ID expr* /* ID is function name */ |
- | | path expr* /* path is external command name */ |
- | ; |
- | |
- | path : ID /* left out slashes and such */ |
- | | "@" ID /* ID is environment var */ |
- | ; |
- | |
- | expr : .... |
- | | "(" expr ")"; |
- | |
- | call : fun_call |
- | | command |
- | ; |
- | |
- | Obviously the call is wildly ambiguous. This is more or less how this |
- | is to be resolved: |
- | |
- | A call begins with an ID or an @ followed by an ID. |
- | |
- | If it is an ID and if it is an ext. command name -> command |
- | if followed by a paren -> fun_call |
- | otherwise -> command |
- | |
- | If it is an @ and if the ID is a var name -> fun_call |
- | otherwise -> command |
- | |
- | One can implement these rules quite neatly using && predicates: |
- | |
- | call : ("@" ID)? && <<isVarName(LT(2))>>? fun_call |
- | | (ID)? && <<isExtCmdName>>? command |
- | | (ID "(")? fun_call |
- | | command |
- | ; |
- | |
- | This can be done better, so it is not an ideal example, but it |
- | conveys the principle. |

-#119. (Changed in 1.33MR11) Ambiguity aid for grammars
-
- The user can ask for additional information on ambiguities reported
- by antlr to stdout. At the moment, only one ambiguity report can
- be created in an antlr run.
-
- This feature is enabled using the "-aa" (Ambiguity Aid) option.
-
- The following options control the reporting of ambiguities:
-
- -aa ruleName Selects reporting by name of rule
- -aa lineNumber Selects reporting by line number
- (file name not compared)
-
- -aam Selects "multiple" reporting for a token
- in the intersection set of the
- alternatives.
-
- For instance, the token ID may appear dozens
- of times in various paths as the program
- explores the rules which are reachable from
- the point of an ambiguity. With option -aam
- every possible path the search program
- encounters is reported.
-
- Without -aam only the first encounter is
- reported. This may result in incomplete
- information, but the information may be
- sufficient and much shorter.
-
- -aad depth Selects the depth of the search.
- The default value is 1.
-
- The number of paths to be searched, and the
- size of the report can grow geometrically
- with the -ck value if a full search for all
- contributions to the source of the ambiguity
- is explored.
-
- The depth represents the number of tokens
- in the lookahead set which are matched against
- the set of ambiguous tokens. A depth of 1
- means that the search stops when a lookahead
- sequence of just one token is matched.
-
- A k=1 ck=6 grammar might generate 5,000 items
- in a report if a full depth 6 search is made
- with the Ambiguity Aid. The source of the
- problem may be in the first token and obscured
- by the volume of data - I hesitate to call
- it information.
-
- When the user selects a depth > 1, the search
- is first performed at depth=1 for both
- alternatives, then depth=2 for both alternatives,
- etc.

- For a linear lookahead set ambiguity (where k=1 or for k>1 but
- when all lookahead sets [i] with i<k all have degree one) the
- reports appear in the following order:
-
- for (depth=1 ; depth <= "-aad depth" ; depth++) {
- for (alternative=1; alternative <=2 ; alternative++) {
- while (matches-are-found) {
- group++;
- print-report
- };
- };

-
- For reporting a k-tuple ambiguity, the reports appear in the
- following order:
-
- for (depth=1 ; depth <= "-aad depth" ; depth++) {
- while (matches-are-found) {
- for (alternative=1; alternative <=2 ; alternative++) {
- group++;
- print-report
- };
- };
- };
-
- This is because matches are generated in different ways for
- linear lookahead and k-tuples.

-#117. (Changed in 1.33MR10) new EXPERIMENTAL predicate hoisting code
-
- The hoisting of predicates into rules to create prediction
- expressions is a problem in antlr. Consider the following
- example (k=1 with -prc on):
-
- start : (a)* "@" ;
- a : b | c ;
- b : <<isUpper(LATEXT(1))>>? A ;
- c : A ;
-
- Prior to 1.33MR10 the code generated for "start" would resemble:
-
- while {
- if (LA(1)==A &&
- (!LA(1)==A || isUpper())) {
- a();
- }
- };
-
- This code is wrong because it makes rule "c" unreachable from
- "start". The essence of the problem is that antlr fails to
- recognize that there can be a valid alternative within "a" even
- when the predicate <<isUpper(LATEXT(1))>>? is false.
-
- In 1.33MR10 with -mrhoist the hoisting of the predicate into
- "start" is suppressed because it recognizes that "c" can
- cover all the cases where the predicate is false:
-
- while {
- if (LA(1)==A) {
- a();
- }
- };
-
- With the antlr "-info p" switch the user will receive information
- about the predicate suppression in the generated file:
-
- --------------------------------------------------------------
- #if 0
-
- Hoisting of predicate suppressed by alternative without predicate.
- The alt without the predicate includes all cases where
- the predicate is false.
-
- WITH predicate: line 7 v1.g
- WITHOUT predicate: line 7 v1.g
-
- The context set for the predicate:
-
- A
-
- The lookahead set for the alt WITHOUT the semantic predicate:
-
- A
-
- The predicate:
-
- pred << isUpper(LATEXT(1))>>?
- depth=k=1 rule b line 9 v1.g
- set context:
- A
- tree context: null
-
- Chain of referenced rules:
-
- #0 in rule start (line 5 v1.g) to rule a
- #1 in rule a (line 7 v1.g)
-
- #endif
- --------------------------------------------------------------
-
- A predicate can be suppressed by a combination of alternatives
- which, taken together, cover a predicate:
-
- start : (a)* "@" ;
-
- a : b | ca | cb | cc ;
-
- b : <<isUpper(LATEXT(1))>>? ( A | B | C ) ;
-
- ca : A ;
- cb : B ;
- cc : C ;
-
- Consider a more complex example in which "c" covers only part of
- a predicate:
-
- start : (a)* "@" ;
-
- a : b
- | c
- ;
-
- b : <<isUpper(LATEXT(1))>>?
- ( A
- | X
- );
-
- c : A
- ;
-
- Prior to 1.33MR10 the code generated for "start" would resemble:
-
- while {
- if ( (LA(1)==A || LA(1)==X) &&
- (! (LA(1)==A || LA(1)==X) || isUpper()) {
- a();
- }
- };
-
- With 1.33MR10 and -mrhoist the predicate context is restricted to
- the non-covered lookahead. The code resembles:
-
- while {
- if ( (LA(1)==A || LA(1)==X) &&
- (! (LA(1)==X) || isUpper()) {
- a();
- }
- };
-
- With the antlr "-info p" switch the user will receive information
- about the predicate restriction in the generated file:
-
- --------------------------------------------------------------
- #if 0
-
- Restricting the context of a predicate because of overlap
- in the lookahead set between the alternative with the
- semantic predicate and one without
- Without this restriction the alternative without the predicate
- could not be reached when input matched the context of the

-
- WITH predicate: line 11 v4.g
- WITHOUT predicate: line 12 v4.g

-
- #endif
- --------------------------------------------------------------
-
- The bad news about -mrhoist:
-
- (a) -mrhoist does not analyze predicates with lookahead
- depth > 1.
-
- (b) -mrhoist does not look past a guarded predicate to
- find context which might cover other predicates.
-
- For these cases you might want to use syntactic predicates.
- When a semantic predicate fails during guess mode the guess
- fails and the next alternative is tried.
-
- Limitation (a) is illustrated by the following example:
-
- start : (stmt)* EOF ;
-
- stmt : cast
- | expr
- ;
- cast : <<isTypename(LATEXT(2))>>? LP ID RP ;
-
- expr : LP ID RP ;
-
- This is not much different from the first example, except that
- it requires two tokens of lookahead context to determine what
- to do. This predicate is NOT suppressed because the current version
- is unable to handle predicates with depth > 1.
-
- A predicate can be combined with other predicates during hoisting.
- In those cases the depth=1 predicates are still handled. Thus,
- in the following example the isUpper() predicate will be suppressed
- by line #4 when hoisted from "bizarre" into "start", but will still
- be present in "bizarre" in order to predict "stmt".
-
- start : (bizarre)* EOF ; // #1
- // #2
- bizarre : stmt // #3
- | A // #4
- ;
-
- stmt : cast
- | expr
- ;
-
- cast : <<isTypename(LATEXT(2))>>? LP ID RP ;
-
- expr : LP ID RP ;
- | <<isUpper(LATEXT(1))>>? A
-
- Limitation (b) is illustrated by the following example of a
- context guarded predicate:
-
- rule : (A)? <<p>>? // #1
- (A // #2
- |B // #3
- ) // #4
- | <<q>> B // #5
- ;
-
- Recall that this means that when the lookahead is NOT A then
- the predicate "p" is ignored and it attempts to match "A|B".
- Ideally, the "B" at line #3 should suppress predicate "q".
- However, the current version does not attempt to look past
- the guard predicate to find context which might suppress other
- predicates.
-
- In some cases -mrhoist will lead to the reporting of ambiguities
- which were not visible before:
-
- start : (a)* "@";
- a : bc | d;
- bc : b | c ;
-
- b : <<isUpper(LATEXT(1))>>? A;
- c : A ;
-
- d : A ;
-
- In this case there is a true ambiguity in "a" between "bc" and "d"
- which can both match "A". Without -mrhoist the predicate in "b"
- is hoisted into "a" and there is no ambiguity reported. However,
- with -mrhoist, the predicate in "b" is suppressed by "c" (as it
- should be) making the ambiguity in "a" apparent.
-
- The motivations for these changes were hoisting problems reported
- by Reinier van den Born (reinier@vnet.ibm.com) and several others.
-
-#113. (Changed in 1.33MR10) new context guarded pred: (g)? && <<p>>? expr
-
- The existing context guarded predicate:
-
- rule : (guard)? => <<p>>? expr
- | next_alternative
- ;
-
- generates code which resembles:
-
- if (lookahead(expr) && (!guard || pred)) {
- expr()
- } else ....
-
- This is not suitable for some applications because it allows
- expr() to be invoked when the predicate is false. This is
- intentional because it is meant to mimic automatically computed
- predicate context.
-
- The new context guarded predicate uses the guard information
- differently because it has a different goal. Consider:
-
- rule : (guard)? && <<p>>? expr
- | next_alternative
- ;
-
- The new style of context guarded predicate is equivalent to:
-
- rule : <<guard==true && pred>>? expr
- | next_alternative
- ;
-
- It generates code which resembles:
-
- if (lookahead(expr) && guard && pred) {
- expr();
- } else ...
-
- Both forms of guarded predicates severely restrict the form of
- the context guard: it can contain no rule references, no
- (...)*, no (...)+, and no {...}. It may contain token and
- token class references, and alternation ("|").
-
- Addition for 1.33MR11: in the token expression all tokens must
- be at the same height of the token tree:
-
- (A ( B | C))? && ... is ok (all height 2)
- (A ( B | ))? && ... is not ok (some 1, some 2)
- (A B C D | E F G H)? && ... is ok (all height 4)
- (A B C D | E )? && ... is not ok (some 4, some 1)
-
- This restriction is required in order to properly compute the lookahead
- set for expressions like:
-
- rule1 : (A B C)? && <<pred>>? rule2 ;
- rule2 : (A|X) (B|Y) (C|Z);
-
- This addition was suggested by Rienier van den Born (reinier@vnet.ibm.com)
-
-#109. (Changed in 1.33MR10) improved trace information
-
- The quality of the trace information provided by the "-gd"
- switch has been improved significantly. Here is an example
- of the output from a test program. It shows the rule name,
- the first token of lookahead, the call depth, and the guess
- status:
-
- exit rule gusxx {"?"} depth 2
- enter rule gusxx {"?"} depth 2
- enter rule gus1 {"o"} depth 3 guessing
- guess done - returning to rule gus1 {"o"} at depth 3
- (guess mode continues - an enclosing guess is still active)
- guess done - returning to rule gus1 {"Z"} at depth 3
- (guess mode continues - an enclosing guess is still active)
- exit rule gus1 {"Z"} depth 3 guessing
- guess done - returning to rule gusxx {"o"} at depth 2 (guess mode ends)
- enter rule gus1 {"o"} depth 3
- guess done - returning to rule gus1 {"o"} at depth 3 (guess mode ends)
- guess done - returning to rule gus1 {"Z"} at depth 3 (guess mode ends)
- exit rule gus1 {"Z"} depth 3
- line 1: syntax error at "Z" missing SC
- ...
-
- Rule trace reporting is controlled by the value of the integer
- [zz]traceOptionValue: when it is positive tracing is enabled,
- otherwise it is disabled. Tracing during guess mode is controlled
- by the value of the integer [zz]traceGuessOptionValue. When
- it is positive AND [zz]traceOptionValue is positive rule trace
- is reported in guess mode.
-
- The values of [zz]traceOptionValue and [zz]traceGuessOptionValue
- can be adjusted by subroutine calls listed below.
-
- Depending on the presence or absence of the antlr -gd switch
- the variable [zz]traceOptionValueDefault is set to 0 or 1. When
- the parser is initialized or [zz]traceReset() is called the
- value of [zz]traceOptionValueDefault is copied to [zz]traceOptionValue.
- The value of [zz]traceGuessOptionValue is always initialzed to 1,
- but, as noted earlier, nothing will be reported unless
- [zz]traceOptionValue is also positive.
-
- When the parser state is saved/restored the value of the trace
- variables are also saved/restored. If a restore causes a change in
- reporting behavior from on to off or vice versa this will be reported.
-
- When the -gd option is selected, the macro "#define zzTRACE_RULES"
- is added to appropriate output files.
-
- C++ mode
- --------
- int traceOption(int delta)
- int traceGuessOption(int delta)
- void traceReset()
- int traceOptionValueDefault
-
- C mode
- --------
- int zzTraceOption(int delta)
- int zzTraceGuessOption(int delta)
- void zzTraceReset()
- int zzTraceOptionValueDefault
-
- The argument "delta" is added to the traceOptionValue. To
- turn on trace when inside a particular rule one:
-
- rule : <<traceOption(+1);>>
- (
- rest-of-rule
- )
- <<traceOption(-1);>>
- ; /* fail clause */ <<traceOption(-1);>>
-
- One can use the same idea to turn *off* tracing within a
- rule by using a delta of (-1).
-
- An improvement in the rule trace was suggested by Sramji
- Ramanathan (ps@kumaran.com).

-#108. A Note on Deallocation of Variables Allocated in Guess Mode
-
- NOTE
- ------------------------------------------------------
- This mechanism only works for heap allocated variables
- ------------------------------------------------------
-
- The rewrite of the trace provides the machinery necessary
- to properly free variables or undo actions following a
- failed guess.
-
- The macro zzUSER_GUESS_HOOK(guessSeq,zzrv) is expanded
- as part of the zzGUESS macro. When a guess is opened
- the value of zzrv is 0. When a longjmp() is executed to
- undo the guess, the value of zzrv will be 1.
-
- The macro zzUSER_GUESS_DONE_HOOK(guessSeq) is expanded
- as part of the zzGUESS_DONE macro. This is executed
- whether the guess succeeds or fails as part of closing
- the guess.
-
- The guessSeq is a sequence number which is assigned to each
- guess and is incremented by 1 for each guess which becomes
- active. It is needed by the user to associate the start of
- a guess with the failure and/or completion (closing) of a
- guess.
-
- Guesses are nested. They must be closed in the reverse
- of the order that they are opened.
-
- In order to free memory used by a variable during a guess
- a user must write a routine which can be called to
- register the variable along with the current guess sequence
- number provided by the zzUSER_GUESS_HOOK macro. If the guess
- fails, all variables tagged with the corresponding guess
- sequence number should be released. This is ugly, but
- it would require a major rewrite of antlr 1.33 to use
- some mechanism other than setjmp()/longjmp().
-
- The order of calls for a *successful* guess would be:
-
- zzUSER_GUESS_HOOK(guessSeq,0);
- zzUSER_GUESS_DONE_HOOK(guessSeq);
-
- The order of calls for a *failed* guess would be:
-
- zzUSER_GUESS_HOOK(guessSeq,0);
- zzUSER_GUESS_HOOK(guessSeq,1);
- zzUSER_GUESS_DONE_HOOK(guessSeq);
-
- The default definitions of these macros are empty strings.
-
- Here is an example in C++ mode. The zzUSER_GUESS_HOOK and
- zzUSER_GUESS_DONE_HOOK macros and myGuessHook() routine
- can be used without change in both C and C++ versions.

-
- Remember:

- (a) Only init-actions are executed during guess mode.
- (b) A rule can be invoked multiple times during guess mode.
- (c) If the guess succeeds the rule will be called once more
- without guess mode so that normal actions will be executed.
- This means that the init-action might need to distinguish
- between guess mode and non-guess mode using the variable
- [zz]guessing.

-#101. (Changed in 1.33MR10) antlr -info command line switch
-
- -info
-
- p - extra predicate information in generated file
-
- t - information about tnode use:
- at the end of each rule in generated file
- summary on stderr at end of program
-
- m - monitor progress
- prints name of each rule as it is started
- flushes output at start of each rule
-
- f - first/follow set information to stdout
-
- 0 - no operation (added in 1.33MR11)
-
- The options may be combined and may appear in any order.
- For example:
-
- antlr -info ptm -CC -gt -mrhoist on mygrammar.g
-
-#100a. (Changed in 1.33MR10) Predicate tree simplification
-
- When the same predicates can be referenced in more than one
- alternative of a block large predicate trees can be formed.
-
- The difference that these optimizations make is so dramatic
- that I have decided to use it even when -mrhoist is not selected.
-
- Consider the following grammar:
-
- start : ( all )* ;
-
- all : a
- | d
- | e
- | f
- ;
-
- a : c A B
- | c A C
- ;
-
- c : <<AAA(LATEXT(2))>>?
- ;
-
- d : <<BBB(LATEXT(2))>>? B C
- ;
-
- e : <<CCC(LATEXT(2))>>? B C
- ;
-
- f : e X Y
- ;
-
- In rule "a" there is a reference to rule "c" in both alternatives.
- The length of the predicate AAA is k=2 and it can be followed in
- alternative 1 only by (A B) while in alternative 2 it can be
- followed only by (A C). Thus they do not have identical context.
-
- In rule "all" the alternatives which refer to rules "e" and "f" allow
- elimination of the duplicate reference to predicate CCC.
-
- The table below summarized the kind of simplification performed by
- 1.33MR10. In the table, X and Y stand for single predicates
- (not trees).
-
- (OR X (OR Y (OR Z))) => (OR X Y Z)
- (AND X (AND Y (AND Z))) => (AND X Y Z)
-
- (OR X (... (OR X Y) ... )) => (OR X (... Y ... ))
- (AND X (... (AND X Y) ... )) => (AND X (... Y ... ))
- (OR X (... (AND X Y) ... )) => (OR X (... ... ))
- (AND X (... (OR X Y) ... )) => (AND X (... ... ))
-
- (AND X) => X
- (OR X) => X
-
- In a test with a complex grammar for a real application, a predicate
- tree with six OR nodes and 12 leaves was reduced to "(OR X Y Z)".
-
- In 1.33MR10 there is a greater effort to release memory used
- by predicates once they are no longer in use.
-
-#100b. (Changed in 1.33MR10) Suppression of extra predicate tests
-
- The following optimizations require that -mrhoist be selected.
-
- It is relatively easy to optimize the code generated for predicate
- gates when they are of the form:
-
- (AND X Y Z ...)
- or (OR X Y Z ...)
-
- where X, Y, Z, and "..." represent individual predicates (leaves) not
- predicate trees.
-
- If the predicate is an AND the contexts of the X, Y, Z, etc. are
- ANDed together to create a single Tree context for the group and
- context tests for the individual predicates are suppressed:
-
- --------------------------------------------------
- Note: This was incorrect. The contexts should be
- ORed together. This has been fixed. A more
- complete description is available in item #152.
- ---------------------------------------------------
-
- Optimization 1: (AND X Y Z ...)
-
- Suppose the context for Xtest is LA(1)==LP and the context for
- Ytest is LA(1)==LP && LA(2)==ID.
-
- Without the optimization the code would resemble:
-
- if (lookaheadContext &&
- !(LA(1)==LP && LA(1)==LP && LA(2)==ID) ||
- ( (! LA(1)==LP || Xtest) &&
- (! (LA(1)==LP || LA(2)==ID) || Xtest)
- )) {...
-
- With the -mrhoist optimization the code would resemble:
-
- if (lookaheadContext &&
- ! (LA(1)==LP && LA(2)==ID) || (Xtest && Ytest) {...
-
- Optimization 2: (OR X Y Z ...) with identical contexts
-
- Suppose the context for Xtest is LA(1)==ID and for Ytest
- the context is also LA(1)==ID.
-
- Without the optimization the code would resemble:
-
- if (lookaheadContext &&
- ! (LA(1)==ID || LA(1)==ID) ||
- (LA(1)==ID && Xtest) ||
- (LA(1)==ID && Ytest) {...
-
- With the -mrhoist optimization the code would resemble:
-
- if (lookaheadContext &&
- (! LA(1)==ID) || (Xtest || Ytest) {...
-
- Optimization 3: (OR X Y Z ...) with distinct contexts
-
- Suppose the context for Xtest is LA(1)==ID and for Ytest
- the context is LA(1)==LP.
-
- Without the optimization the code would resemble:
-
- if (lookaheadContext &&
- ! (LA(1)==ID || LA(1)==LP) ||
- (LA(1)==ID && Xtest) ||
- (LA(1)==LP && Ytest) {...
-
- With the -mrhoist optimization the code would resemble:
-
- if (lookaheadContext &&
- (zzpf=0,
- (LA(1)==ID && (zzpf=1) && Xtest) ||
- (LA(1)==LP && (zzpf=1) && Ytest) ||
- !zzpf) {
-
- These may appear to be of similar complexity at first,
- but the non-optimized version contains two tests of each
- context while the optimized version contains only one
- such test, as well as eliminating some of the inverted
- logic (" !(...) || ").
-
- Optimization 4: Computation of predicate gate trees
-
- When generating code for the gates of predicate expressions
- antlr 1.33 vanilla uses a recursive procedure to generate
- "&&" and "||" expressions for testing the lookahead. As each
- layer of the predicate tree is exposed a new set of "&&" and
- "||" expressions on the lookahead are generated. In many
- cases the lookahead being tested has already been tested.
-
- With -mrhoist a lookahead tree is computed for the entire
- lookahead expression. This means that predicates with identical
- context or context which is a subset of another predicate's
- context disappear.
-
- This is especially important for predicates formed by rules
- like the following:
-
- uppperCaseVowel : <<isUpperCase(LATEXT(1))>>? vowel;
- vowel: : <<isVowel(LATEXT(1))>>? LETTERS;
-
- These predicates are combined using AND since both must be
- satisfied for rule upperCaseVowel. They have identical
- context which makes this optimization very effective.
-
- The affect of Items #100a and #100b together can be dramatic. In
- a very large (but real world) grammar one particular predicate
- expression was reduced from an (unreadable) 50 predicate leaves,
- 195 LA(1) terms, and 5500 characters to an (easily comprehensible)
- 3 predicate leaves (all different) and a *single* LA(1) term.
-
-#98. (Changed in 1.33MR10) Option "-info p"
-
- When the user selects option "-info p" the program will generate
- detailed information about predicates. If the user selects
- "-mrhoist on" additional detail will be provided explaining
- the promotion and suppression of predicates. The output is part
- of the generated file and sandwiched between #if 0/#endif statements.
-
- Consider the following k=1 grammar:
-
- start : ( all ) * ;
-
- all : ( a
- | b
- )
- ;
-
- a : c B
- ;
-
- c : <<LATEXT(1)>>?
- | B
- ;
-
- b : <<LATEXT(1)>>? X
- ;
-
- Below is an excerpt of the output for rule "start" for the three
- predicate options (off, on, and maintenance release style hoisting).
-
- For those who do not wish to use the "-mrhoist on" option for code
- generation the option can be used in a "diagnostic" mode to provide
- valuable information:
-
- a. where one should insert null actions to inhibit hoisting
- b. a chain of rule references which shows where predicates are
- being hoisted

-#60. (Changed in 1.33MR7) Major changes to exception handling
-
- There were significant problems in the handling of exceptions
- in 1.33 vanilla. The general problem is that it can only
- process one level of exception handler. For example, a named
- exception handler, an exception handler for an alternative, or
- an exception for a subrule always went to the rule's exception
- handler if there was no "catch" which matched the exception.
-
- In 1.33MR7 the exception handlers properly "nest". If an
- exception handler does not have a matching "catch" then the
- nextmost outer exception handler is checked for an appropriate
- "catch" clause, and so on until an exception handler with an
- appropriate "catch" is found.
-
- There are still undesirable features in the way exception
- handlers are implemented, but I do not have time to fix them
- at the moment:
-
- The exception handlers for alternatives are outside the
- block containing the alternative. This makes it impossible
- to access variables declared in a block or to resume the
- parse by "falling through". The parse can still be easily
- resumed in other ways, but not in the most natural fashion.
-
- This results in an inconsistentcy between named exception
- handlers and exception handlers for alternatives. When
- an exception handler for an alternative "falls through"
- it goes to the nextmost outer handler - not the "normal
- action".
-
- A major difference between 1.33MR7 and 1.33 vanilla is
- the default action after an exception is caught:
-
- 1.33 Vanilla
- ------------
- In 1.33 vanilla the signal value is set to zero ("NoSignal")
- and the code drops through to the code following the exception.
- For named exception handlers this is the "normal action".
- For alternative exception handlers this is the rule's handler.
-
- 1.33MR7
- -------
- In 1.33MR7 the signal value is NOT automatically set to zero.
-
- There are two cases:
-
- For named exception handlers: if the signal value has been
- set to zero the code drops through to the "normal action".
-
- For all other cases the code branches to the nextmost outer
- exception handler until it reaches the handler for the rule.
-
- The following macros have been defined for convenience:
-
- C/C++ Mode Name
- --------------------
- (zz)suppressSignal
- set signal & return signal arg to 0 ("NoSignal")
- (zz)setSignal(intValue)
- set signal & return signal arg to some value
- (zz)exportSignal
- copy the signal value to the return signal arg
-
- I'm not sure why PCCTS make a distinction between the local
- signal value and the return signal argument, but I'm loathe
- to change the code. The burden of copying the local signal
- value to the return signal argument can be given to the
- default signal handler, I suppose.
-
-#53. (Explanation for 1.33MR6) What happens after an exception is caught ?
-
- The Book is silent about what happens after an exception
- is caught.
-
- The following code fragment prints "Error Action" followed
- by "Normal Action".
-
- test : Word ex:Number <<printf("Normal Action\n");>>
- exception[ex]
- catch NoViableAlt:
- <<printf("Error Action\n");>>
- ;
-
- The reason for "Normal Action" is that the normal flow of the
- program after a user-written exception handler is to "drop through".
- In the case of an exception handler for a rule this results in
- the exection of a "return" statement. In the case of an
- exception handler attached to an alternative, rule, or token
- this is the code that would have executed had there been no
- exception.
-
- The user can achieve the desired result by using a "return"
- statement.
-
- test : Word ex:Number <<printf("Normal Action\n");>>
- exception[ex]
- catch NoViableAlt:
- <<printf("Error Action\n"); return;>>
- ;
-
- The most powerful mechanism for recovery from parse errors
- in pccts is syntactic predicates because they provide
- backtracking. Exceptions allow "return", "break",
- "consumeUntil(...)", "goto _handler", "goto _fail", and
- changing the _signal value.
-
-#41. (Added in 1.33MR6) antlr -stdout
-
- Using "antlr -stdout ..." forces the text that would
- normally go to the grammar.c or grammar.cpp file to
- stdout.
-
-#40. (Added in 1.33MR6) antlr -tab to change tab stops
-
- Using "antlr -tab number ..." changes the tab stops
- for the grammar.c or grammar.cpp file. The number
- must be between 0 and 8. Using 0 gives tab characters,
- values between 1 and 8 give the appropriate number of
- space characters.
-
-#34. (Added to 1.33MR1) Add public DLGLexerBase::set_line(int newValue)
-
- Previously there was no public function for changing the line
- number maintained by the lexer.
-
-#28. (Added to 1.33MR1) More control over DLG header
-
- Version 1.33MR1 adds the following directives to PCCTS
- for C++ mode:
-
- #lexprefix <<source code>>
-
- Adds source code to the DLGLexer.h file
- after the #include "DLexerBase.h" but
- before the start of the class definition.
-
- #lexmember <<source code>>
-
- Adds source code to the DLGLexer.h file
- as part of the DLGLexer class body. It
- appears immediately after the start of
- the class and a "public: statement.

-#13. dlg reports an invalid range for: [\0x00-\0xff]
-
- Diagnosed by Piotr Eljasiak (eljasiak@no-spam.zt.gdansk.tpsa.pl):
-
- Fixed in MR16.
-
-#12. Strings containing comment actions
-
- Sequences that looked like C style comments appearing in string
- literals are improperly parsed by antlr/dlg.
-
- << fprintf(out," /* obsolete */ ");
-
- For this case use:
-
- << fprintf(out," \/\* obsolete \*\/ ");
-
- Reported by K.J. Cummings (cummings@peritus.com).
-
-#11. User hook for deallocation of variables on guess fail
-
- The mechanism outlined in Item #108 works only for
- heap allocated variables.
-
-#10. Label re-initialization in ( X {y:Y} )*
-
- If a label assignment is optional and appears in a
- (...)* or (...)+ block it will not be reset to NULL
- when it is skipped by a subsequent iteration.
-
- Consider the example:
-
- ( X { y:Y })* Z
-
- with input:
-
- X Y X Z
-
- The first time through the block Y will be matched and
- y will be set to point to the token. On the second
- iteration of the (...)* block there is no match for Y.
- But y will not be reset to NULL, as the user might
- expect, it will contain a reference to the Y that was
- matched in the first iteration.
-
- The work-around is to manually reset y:
-
- ( X << y = NULL; >> { y:Y } )* Z
-
- or
-
- ( X ( y:Y | << y = NULL; >> /* epsilon */ ) )* Z
-
- Reported by Jeff Vincent (JVincent@novell.com).
-
-#9. PCCTAST.h PCCTSAST::setType() is a noop
-
-#8. #tokdefs with ~Token and .
-
- THM: I have been unable to reproduce this problem.
-
- When antlr uses #tokdefs to define tokens the fields of
- #errclass and #tokclass do not get properly defined.
- When it subsequently attempts to take the complement of
- the set of tokens (using ~Token or .) it can refer to
- tokens which don't have names, generating a fatal error.
-
-#7. DLG crashes on some invalid inputs
-
- THM: In MR20 have fixed the most common cases.
-
- The following token defintion will cause DLG to crash.
-
- #token "()"
-
- Reported by Mengue Olivier (dolmen@bigfoot.com).
-
-#6. On MS systems \n\r is treated as two new lines
-
- Fixed.
-
-#5. Token expressions in #tokclass
-
- #errclass does not support TOK1..TOK2 or ~TOK syntax.
- #tokclass does not support ~TOKEN syntax
-
- A workaround for #errclass TOK1..TOK2 is to use a
- #tokclass.
-
- Reported by Dave Watola (dwatola@amtsun.jpl.nasa.gov)
-
-#4. A #tokdef must appear "early" in the grammar file.
-
- The "early" section of the grammar file is the only
- place where the following directives may appear:
-
- #header
- #first
- #tokdefs
- #parser
-
- Any other kind of statement signifiies the end of the
- "early" section.
-
-#3. Use of PURIFY macro for C++ mode
-
- Item #93 of the CHANGES_FROM_1.33 describes the use of
- the PURIFY macro to zero arguments to be passed by
- upward inheritance.
-
- #define PURIFY(r, s) memset((char *) &(r), '\0', (s));
-
- This may not be the right thing to do for C++ objects that
- have constructors. Reported by Bonny Rais (bonny@werple.net.au).
-
- For those cases one should #define PURIFY to be an empty macro
- in the #header or #first actions.
-
-#2. Fixed in 1.33MR10 - See CHANGES_FROM_1.33 Item #80.
-
-#1. The quality of support for systems with 8.3 file names leaves
- much to be desired. Since the kit is distributed using the
- long file names and the make file uses long file names it requires
- some effort to generate. This will probably not be changed due
- to the large number of systems already written using the long
- file names.

-README for pccts 1.33mr20 (Maintenance Release #20) release date 5 August 1999
----------------------------------------------------------------------------------
-
- Parr Research Corporation
- with
- Purdue University Electrical Engineering
- and
- University of Minnesota, AHPCRC
-
- Terence Parr
- Russell Quong
- Will Cohen
- Hank Dietz
-
-
-A central place for information about PCCTS 1.33 is:
-
- http://www.polhode.com/pccts.html
-
-The maintenance release is available from:
-
- http://www.polhode.com/pccts133mr.zip
-
-There is a ready-to-run version for win32 for Microsoft Visual Studio
-at the same site. It is available from:
-
- http://www.polhode.com/win32.zip
-
-There is a newsgroup dedicated to pccts 1.33 and related topics:
-
- comp.compilers.tools.pccts
-
-You may also want to register for the antlr-interest mailing list
-which is provided gratis by the following service:
-
- http://www.onesite.com
-
-New users should visit http://www.polhode.com/pccts.html in
-order to get the following document:
-
- "Notes For New Users of PCCTS"
-
-This is a Postscript file of about 40 pages which is extremely
-useful for someone starting out. It is a based on 1.33mr7 so is a
-little bit out-of-date. The section on semantic predicates is
-very out of date, but I have not had time to revise it.
-
-When you have a little more experience, be sure to review the
-following documents in the distribution kit:
-
- CHANGES_FROM_133.txt
- CHANGES_FROM_133_BEFORE_MR13.txt
- KNOWN_PROBLEMS.txt
-
--------------------------------------------------------------------------
- INSTALLATION (Unix)
--------------------------------------------------------------------------
-0. Download http://www.polhode.com/pccts133mr.zip
-
-1. Unzip the distribution kit to your preferred location.
-
-2. cd to the main pccts directory.
-
-3. make
-
- This will create:
-
- antlr.exe
- dlg.exe
- sorcerer.exe
- genmk.exe
-
-4. Add pccts/bin to your path.
-
-5. To get an up-to-date list of program options execute the
- program with no command line options. To get up-to-date
- documentation read CHANGES_FROM_133*.txt and KNOWN_PROBLEMS.txt
- at:
-
- http://www.polhode.com/pccts.html.
-
-6. You need not create a library. The makefile created by genmk
- assumes that the files are not part of a library.
-
- If you wish to create a library from elements of pccts/h:
-
- If the first letter of the filename is lowercase (uppercase) it is
- related to the code generated using the pccts C mode (C++ mode).
- Some of the .c and .cpp files in the h directory are not meant to
- be placed in a library and will not compile because they are meant
- to be #include in pccts generated files which are grammar specific.
-
- For C++ users place the following elements in the library:
-
- AParser.cpp
- ASTBase.cpp
- ATokenBuffer.cpp
- BufFileInput.cpp (optional)
- DLexerBase.cpp
- PCCTSAST.cpp
- SList.cpp
-
--------------------------------------------------------------------------
- INSTALLATION (Win32)
--------------------------------------------------------------------------
-
-I've tried to keep the win32 kit to the minimum necessary to get
-up and running. The complete kit contains additional information
-(some historical), source code, and DevStudio projects for
-rebuilding pccts from the source code.
-
-The kit is now distributed with both MSVC 5 and MSVC6 style projects.
-
-0. Download http://www.polhode.com/win32.zip.

- http://www.polhode.com/KNOWN_PROBLEMS.txt
-
-1. Unzip the distribution kit to your preferred location.
-
- This will create:
-
- a pccts directory tree
- pccts/bin/*.exe
- pccts/lib/*.lib
- pccts/h/*
- sorcerer/lib/*
- sorcerer/h/*
-
- an example directory tree
- example\calcAST\*
- example\simple\*

- * ast_scan
- *

- *
- * ast_scan("#( 6 #(5 %1:4 %2:3) #(1 %3:3 %4:3) )",
- * t, &w, &x, &y, &z);

- * t, &w, &x, &y, &z);
- *
- * by SORCERER.
- *
- * This function call must be done withing a SORCERER file because SORCERER
- * must convert the token references to the associated token number.
- *
- * This functions parses the template and creates trees which are then
- * matched against the input tree. The labels are set as they are
- * encountered; hence, partial matches may leave some pointers set
- * and some NULL. This routines initializes all argument pointers to NULL
- * at the beginning.
- *
- * This function returns the number of labels matched.

- 2-Oct-97 The routine ast_dup() appeared to have a bug in it. Instead
- of providing a deep copy of its argument it made a bushy copy
- of its argument - by duplicating the nodes pointed to by
- its right link. This is certainly not deliberate and does
- not match code in PCCTSAST.cpp (which had its own bug). This
- has been changed to do a deep copy in the traditional sense.
