2007-06-18Add in incomplete pick and merge functions which read and write pieces of ↵Gabe Black
registers, and fill out microcode disassembly. --HG-- extra : convert_revision : 56332b3999a9079b1bd305ee2826abdf593367e1
2007-06-14Add in some microregs.Gabe Black
--HG-- extra : convert_revision : e8a894c2f7901329bd390a4cfd92209d0e29cf80
2007-06-14Sign extend byte immediates as well. There might need to be a fancier system ↵Gabe Black
in place to handle this in the future. --HG-- extra : convert_revision : 2c5bd719c770d9a93a57bd29782842f82384863d

2007-06-14Get rid of some debug output and let macroops set headers in their ↵Gabe Black
constructor. The intention is to allow them to modify the emulation environment struct before it's used to construct its microops. --HG-- extra : convert_revision : b04fc9ead8e3322fc3af3f14d75e2206ddfbe561
2007-06-13Seperate the pc-pc and the pc of the incoming bytes, and get rid of the ↵Gabe Black
"moreBytes" which just takes a MachInst. src/arch/x86/predecoder.cc: Seperate the pc-pc and the pc of the incoming bytes, and get rid of the "moreBytes" which just takes a MachInst. Also make the "opSize" field describe the number of bytes and not the log of the number of bytes. --HG-- extra : convert_revision : 3a5ec7053ec69c5cba738a475d8b7fd9e6e6ccc0

2007-06-13Move load/store microops into their own file. They still don't do anything, ↵Gabe Black
though. --HG-- extra : convert_revision : 251763c614b9056c3ca7a85ef92c416552da893f
2007-06-13Fix the immediate version of register operations, and get their name to show ↵Gabe Black

2007-06-08Move the microcode assembly to a python package instead of isa_parser files. ↵Gabe Black
Also, the code is now a single string which runs through the microcode assembler rather than docstrings associated with classes named after each architectural level instruction. --HG-- extra : convert_revision : 20e6d6ac625dde8f1885acc445882096df562778

2007-05-31x86 work that hadn't been checked in.Gabe Black
src/arch/x86/isa/decoder/one_byte_opcodes.isa: Give the "MOV" instruction the format of it's arguments. This will likely need to be completely overhauled in the near future. src/arch/x86/predecoder.cc: src/arch/x86/predecoder.hh: Make the predecoder explicitly reset itself rather than counting on it happening naturally. src/arch/x86/predecoder_tables.cc: Fix the immediate size table src/arch/x86/regfile.cc: nextnpc is bogus --HG-- extra : convert_revision : 0926701fedaab41817e64bb05410a25174484a5a

2007-04-10Changed some instruction names to be in all caps, and "implemented" move to ↵Gabe Black
test the stub code for instructions. --HG-- extra : convert_revision : a377daf20545dfcbb0f97d8cafbe3d68416dc4b2
2007-04-10Added a class which lets you manipulate all the strings returned by the ↵Gabe Black

2007-04-10Fix up the base x86 fault object and create a fault to be generated by ↵Gabe Black
unimplemented instructions in their microcode. This is useful if certain variations of an instruction are implemented, but, for instance, it's memory based versions aren't. --HG-- extra : convert_revision : 24e69c5a6a0af2d0cf67e858a051ae6624bb300f

2007-04-06Refactored the x86 isa description some more. There should be more ↵Gabe Black
seperation between x86 specific parts, and those parts which are implemented in the isa description but could eventually be moved elsewhere. --HG-- rename : src/arch/x86/isa/formats/macroop.isa => src/arch/x86/isa/macroop.isa extra : convert_revision : 5ab40eedf574fce438d9fe90e00a496dc95c8bcf
2007-04-06Clean up the code a little, fix (I think) a perceived problem with immediate ↵Gabe Black
