--HG-- extra : convert_revision : 566841577bf4a98cac0b65292fe0f7daf89a9203
2007-08-04X86: Make 64 bit unaligned accesses work as well as the other sizes.Gabe Black
There is a fundemental flaw in how unaligned accesses are supported, but this is still an improvement. --HG-- extra : convert_revision : 1c20b524ac24cd4a812c876b067495ee6a7ae29f
2007-08-04X86: Start implementing segmentation support.Gabe Black
Make instructions observe segment prefixes, default segment rules, segment base addresses. Also fix some microcode and add sib and riprel "keywords" to the x86 specialization of the microassembler. --HG-- extra : convert_revision : be5a3b33d33f243ed6e1ad63faea8495e46d0ac9
2007-08-01X86: Fix for compilation bug with new cache code.Gabe Black
--HG-- extra : convert_revision : 073c6db0796cd2c11b8293b382b438a2a959b821
2007-07-30X86: Remove a naming conflict between the register index parameters and the ↵Gabe Black
"picked" register values. --HG-- extra : convert_revision : 7b2c1be509478153ebf396841e4cbeccee3e03d1
2007-07-30X86: Make instructions use pick, and implement/adjust some multiplication ↵Gabe Black
microops and instructions. --HG-- extra : convert_revision : 5c56f6819ee07d936b388b3d1810a3b73db84f9c
2007-07-30X86: Make disassembly use the final register index. Add bits to indicate ↵Gabe Black
whether or not register indexes should be "folded". --HG-- extra : convert_revision : 4b46e71ca91e480f6e1662b7f37b75240d6598e9
2007-07-29X86: Make logic instructions flag setting work.Gabe Black
The instructions now ask for the appropriate flags to be set, and the microops do the "right thing" with the CF and OF flags, namely zero them. --HG-- extra : convert_revision : 85138a832f44c879bf8a11bd3a35b58be6272ef3
2007-07-29X86: Make limm use merge and allow overriding the data size.Gabe Black
--HG-- extra : convert_revision : c6057226b8ff8f272612a9d3bf7d1d9ba90c819b
2007-07-26X86: Add functions to read and write to an exec context.Gabe Black
These functions take care of calling the thread contexts read and write functions with the right sized data type, and handle unaligned accesses. --HG-- extra : convert_revision : b4b59ab2b22559333035185946bae3eab316c879
2007-07-26X86: Fix carry calculation for subtraction based microops.Gabe Black
The carry flag should be calculated using the -complement- of the second operand, not it's negation. The carry in which is part of computing the 2's complement may induce a carry, but if you've already caused the carry before you get the carry computing logic involved, it will miss it. --HG-- extra : convert_revision : 318cf86929664fc52ed9e023606a9e892eba635c
2007-07-24Make the shift and rotate microops mask the shift/rotate amount correctly.Gabe Black

2007-07-20Fixed the distinction between far and near versions of jmp, call and ret. ↵Gabe Black
Implemented some shifts, rotates, and pushes. --HG-- extra : convert_revision : fcb06189ff213e82da16ac43231feb308cb3a285
2007-07-20Implement adc and sbb instructions and microops.Gabe Black
--HG-- extra : convert_revision : a2d3068c5b487f4fa7bf5c9cebba7753bc390bfa
2007-07-20Define and fill out a lot of different instructions and instruction ↵Gabe Black
versions. Added two of the shift microops. --HG-- extra : convert_revision : 0b76953dbb1dc3366242d4d209cccebde86bbe4e
2007-07-20Make load and store ops use the appropriate sized data access.Gabe Black

2007-07-20Fix carry flag for subtracts, and clean up code slightly.Gabe Black
--HG-- extra : convert_revision : 668f5d5aeba888488b41284de6c72a0d055c4ef4
2007-07-19x86 fixesGabe Black
Make the emulation environment consider the rex prefix. Implement and hook in forms of j, jmp, cmp, syscall, movzx Added a format for an instruction to carry a call to the SE mode syscalls system Made memory instructions which refer to the rip do so directly Made the operand size overridable in the microassembly Made the "ext" field of register operations 16 bits to hold a sparse encoding of flags to set or conditions to predicate on Added an explicit "rax" operand for the syscall format Implemented syscall returns. --HG-- extra : convert_revision : ae84bd8c6a1d400906e17e8b8c4185f2ebd4c5f2
2007-07-18Make instructions that conditionally set registers set them to their old ↵Gabe Black
value if they don't actually execute. --HG-- extra : convert_revision : 36e63dd0c6ac1a3e1133c7985cf5507b83e9ee45
2007-07-18Make store microops actually store instead of load.Gabe Black
--HG-- extra : convert_revision : fe90f8adc96dd0e680cfa45e4c510a906046ae3d
2007-07-18Make the data size used by regops overridable in the microassembly.Gabe Black
--HG-- extra : convert_revision : 84d850aa5340c9d02d03502704b063215f6e2140
2007-07-18Add a generateDisassembly function to the MicroFault StaticInst.Gabe Black
--HG-- extra : convert_revision : 73811bf99b26fad413c9b84a54f44e3763ff1835
2007-07-17Make disassembled x86 register indices reflect their size.Gabe Black
This doesn't handle high byte register accesses. It also highlights the fact that address size isn't actually being calculated, and that the size a microop uses needs to be overridable from the microassembly. --HG-- extra : convert_revision : d495ac4f5756dc55a5f71953ff6963b3c030e6cb
2007-07-17Add in support for condition code flags.Gabe Black
Some microops can set the condition codes, and some of them can be predicated on them. Some of the codes aren't implemented because it was unclear from the AMD patent what they actually did. They are used with string instructions, but they use variables IP, DTF, and SSTF which don't appear to be documented. --HG-- extra : convert_revision : 2236cccd07d0091762b50148975f301bb1d2da3f
2007-07-14Pull some hard coded base classes out of the isa description.Gabe Black
--HG-- rename : src/arch/x86/isa/base.isa => src/arch/x86/isa/outputblock.isa extra : convert_revision : 7954e7d5eea3b5966c9e273a08bcd169a39f380c
2007-06-21Add in code that lays the ground work for setting flags.Gabe Black
--HG-- extra : convert_revision : e4fcb64d45804700a0ef34e8acf5615b66e2a527
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
2007-06-19More faithfulness to what instructions should work in what modes, and added ↵Gabe Black
the MOVSXD instruction. --HG-- extra : convert_revision : 38b9bf6cd4bdec6355b1158967c7d3562715cacd
2007-06-19Make instructions that are illegal in 64 bit mode not do the wrong thing in ↵Gabe Black
64 bit mode. Also add in more versions of PUSH and POP, and a version of near CALL. --HG-- extra : convert_revision : 7d8266cdfa54ac25610466b3533d3e9e5433297b
2007-06-19Renovate the "fault" microop implementation.Gabe Black
--HG-- extra : convert_revision : dc9d67dd5413f00f16d37cb2d0f8b0d10971e14a
2007-06-19Get rid of the immediate and displacement components of the EmulEnv struct ↵Gabe Black
and use them directly out of the instruction. The extra copies are conceptually realistic but are just innefficient as implemented. Also don't use the zeroeth microcode register for general storage since it's now the zero register, and implement a load and a store microops. --HG-- extra : convert_revision : 0686296ca8b72940d961ecc6051063bfda1e932d
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
2007-06-14Fix limm.Gabe Black

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
up correctly. --HG-- extra : convert_revision : 9fc36b99c9027e35f22983d5d1e22c940fa093de
2007-06-12Make microOp vs microop and macroOp vs macroop capitilization consistent.Gabe Black
src/arch/x86/isa/macroop.isa: Make microOp vs microop and macroOp vs macroop capitilization consistent. Also fill out the emulation environment handling a little more, and use an object to pass around output code. src/arch/x86/isa/microops/base.isa: Make microOp vs microop and macroOp vs macroop capitilization consistent. Also adjust python to C++ bool translation. --HG-- extra : convert_revision : 6f4bacfa334c42732c845f9a7f211cbefc73f96f
