-Module Name:
-
- GenDepex.c
-
-Abstract:
-
- Generate Dependency Expression ("GenDepex")
-
- Infix to Postfix Algorithm
-
- This code has been scrubbed to be free of having any EFI core tree dependencies.
- It should build in any environment that supports a standard C-library w/ string
- operations and File I/O services.
-
- As an example of usage, consider the following:
-
- The input user file could be something like "Sample.DXS" whose contents are
-
- #include "Tiano.h"
-
- DEPENDENCY_START
- NOT (DISK_IO_PROTOCOL AND SIMPLE_FILE_SYSTEM_PROTOCOL)
- OR EFI_PXE_BASE_CODE_PROTOCOL
- DEPENDENCY_END
-
- This file is then washed through the C-preprocessor, viz.,
-
- cl /EP Sample.DXS > Sample.TMP1
-
- This yields the following file "Sample.TMP1" whose contents are
-
- DEPENDENCY_START
- NOT ({ 0xce345171, 0xba0b, 0x11d2, 0x8e, 0x4f, 0x0, 0xa0, 0xc9, 0x69, 0x72,
- 0x3b } AND { 0x964e5b22, 0x6459, 0x11d2, 0x8e, 0x39, 0x0, 0xa0, 0xc9, 0x69,
- 0x72, 0x3b }) OR { 0x03c4e603, 0xac28, 0x11d3, 0x9a, 0x2d, 0x00, 0x90, 0x27,
- 0x3f, 0xc1, 0x4d }
- DEPENDENCY_END
-
- This file, in turn, will be fed into the utility, viz.,
-
- GenDepex Sample.TMP1 Sample.TMP2
-
- With a file that is 55 bytes long:
-
- 55 bytes for the grammar binary
- PUSH opcode - 1 byte
- GUID Instance - 16 bytes
- PUSH opcode - 1 byte
- GUID Instance - 16 bytes
- AND opcode - 1 byte
- NOT opcode - 1 byte
- PUSH opcode - 1 byte
- GUID Instance - 16 bytes
- OR opcode - 1 byte
- END opcode - 1 byte
-
- The file "Sample.TMP2" could be fed via a Section-builder utility
- (GenSection) that would be used for the creation of a dependency
- section file (.DPX) which in turn would be used by a generate FFS
- utility (GenFfsFile) to produce a DXE driver/core (.DXE) or
- a DXE application (.APP) file.
-
- Complies with Tiano C Coding Standards Document, version 0.31, 12 Dec 2000.

-GenerateDependencyExpression (

- IN OUT FILE *OutFile,
- IN INT8 Padding OPTIONAL
- )
-/*++
-
-Routine Description:
-
- This takes the pre-compiled dependency text file and
- converts it into a binary dependency file.
-
- The BNF for the dependency expression is as follows
- (from the DXE 1.0 Draft specification).
-
- The inputted BNF grammar is thus:
- <depex> ::= sor <dep> |
- before GUID <dep> |
- after GUID <dep> |
- <bool>
-
- <dep> ::= <bool> |
-
- <bool> ::= <bool> and <term> |
- <bool> or <term> |
- <term>
-
- <term> ::= not <factor> |
- <factor>
-
- <factor> ::= ( <bool> ) |
- <term> <term> |
- GUID |
- <boolval>
-
- <boolval> ::= true |
- false
-
- The outputed binary grammer is thus:
- <depex> ::= sor <dep> |
- before <depinst> <dep> |
- after <depinst> <dep> |
- <bool>
-
- <dep> ::= <bool> |
-
- <bool> ::= <bool> and <term> |
- <bool> or <term> | <term>
-
- <term> ::= not <factor> |
- <factor>
-
- <factor> ::= ( <bool> ) |
- <term> <term> |
- <boolval> |
- <depinst> |
- <termval>
-
- <boolval> ::= true |
- false
-
- <depinst> ::= push GUID
-
- <termval> ::= end
-
- BugBug: A correct grammer is parsed correctly. A file that violates the
- grammer may parse when it should generate an error. There is some
- error checking and it covers most of the case when it's an include
- of definition issue. An ill formed expresion may not be detected.
-
-Arguments:
-
- InFile - Input pre-compiled text file of the dependency expression.
- This needs to be in ASCII.
- The file pointer can not be NULL.
-
- OutFile - Binary dependency file.
- The file pointer can not be NULL.
-
- Padding - OPTIONAL integer value to pad the output file to.
-
-
-Returns:
-
- EFI_SUCCESS The function completed successfully.
- EFI_INVALID_PARAMETER One of the parameters in the text file was invalid.
- EFI_OUT_OF_RESOURCES Unable to allocate memory.
- EFI_ABORTED An misc error occurred.
