2007-10-07X86: Make sure there are fewer spurious differences between instructions for ↵Gabe Black
caching purposes. --HG-- extra : convert_revision : 7e6be1c42f28f92d9e8b47169e683827bb3f4aaf
2007-10-02Predecoder: Clear out predecoder state on an ITLB fault.Gabe Black
--HG-- extra : convert_revision : 68f8ff778dbd28ade5070edf5a7d662e7bf0045a
2007-07-24Add a special case for "test" which needs an immediate even though ↵Gabe Black
everything else with it's opcode doesn't. Also made some spacing consistent. --HG-- extra : convert_revision : 72a317f29c11705782e19840bef24354214d3143
2007-07-22Fixed immediate byte accounting bug.Gabe Black
--HG-- extra : convert_revision : ee5275da14a2923b9a525ae5b5c582c15df4608a
2007-07-22Fixed displacement size bug.Gabe Black
--HG-- extra : convert_revision : c39249ef598c1bd555098d688381dc62541a07c0
2007-07-20Fix code that computes displacement size.Gabe Black
--HG-- extra : convert_revision : a9be3eb2b90b88086936aeb4dcf87ec7b58a48cb
2007-07-17Calculate the correct address size.Gabe Black
--HG-- extra : convert_revision : 6bd9d5a01ba6600781e3678e0403dca524fb2cba
2007-06-20Fix a newly introduced bug where the predecoder wasn't picking up all the ↵Gabe Black
displacement. --HG-- extra : convert_revision : 9202c11ee187458adcd85ba616b7f7f4bdd4eec1
2007-06-20Make memory instructions work better, add more macroop implementations, add ↵Gabe Black
an lea microop, move EmulEnv into it's own .cc and .hh. --HG-- extra : convert_revision : 1212b8463eab1c1dcba7182c487d1e9184cf9bea
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
2007-06-14Put the mode in the ExtMachInst.Gabe Black
--HG-- extra : convert_revision : 7fc6567ab3d35c06901e6c8a0435f7cab819e17e
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
2007-06-12Reset the rex and legacy prefix components of the ExtMachInst as well.Gabe Black
--HG-- extra : convert_revision : 832a324fec2d2b59f1c101d7fa72d7f670f0495d
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
2007-04-06Clean up the code a little, fix (I think) a perceived problem with immediate ↵Gabe Black
sizes, and sign extend the 32-bit-acting-like-64-bit-immediates. --HG-- extra : convert_revision : e59b747198cc79d50045bd2dc45b2e2b97bbffcc
2007-04-03Zero out ModRM if the byte isn't there, and fix some displacement size stuff.Gabe Black
--HG-- extra : convert_revision : f43abf33a223a665b30098c63011fb162200d5e6
2007-03-21Break out the one and two byte opcodes into different files. Also change ↵Gabe Black
what bits decode is done on to reflect where clumps of instructions are. --HG-- extra : convert_revision : 8768676eac25e6a4f0dc50ce2dc576bdcdd6e025
2007-03-15File with the predecoder in it.Gabe Black
src/arch/x86/predecoder.cc: File for the x86 predecoder process function. --HG-- extra : convert_revision : f7b53c38ff152cb2677d641074218ffd8434457b
