--HG-- extra : convert_revision : 949737d0f5d6fe4aa77cc4680d0c88caab3e8174
2007-09-04X86: Make the movfp microop use FloatRegBits instead of FloatRegs.Gabe Black
This fixes a problem where interpreting arbitrary bits as floating point would change what the value was. These values are legitimate because the fp registers could be used to move around arbitrary data. --HG-- extra : convert_revision : f1d7159ba137702b5722cc7c1b64ed7dd06c21de
2007-09-04X86: Hook in the fp arithmetic instructions. Stale python made it work before.Gabe Black

2007-09-04X86: Fix a corner case where mul would overwrite an original register value ↵Gabe Black
it still needed. --HG-- extra : convert_revision : 86ee0e2bf716d52c34ee731727d6366935f103ed
2007-08-31X86: Major rework of how regop microops are generated.Gabe Black
The new implementation uses metaclass, and gives a lot more precise control with a lot less verbosity. The flags/no flags reg/imm variants are all handled by the same python class now which supplies a constructor to the right C++ class based on context. --HG-- extra : convert_revision : 712e3ec6de7a5a038da083f79635fd7a687d56e5
2007-08-29X86: Fix the sra microop to get the sign bit from the right operand.Gabe Black

--HG-- extra : convert_revision : 1a2813b2e7d3e0e02c8f1474f372de5cf16e7d7b
2007-08-28X86: More fully decode two byte opcodes.Gabe Black
This includes the most of the SSE stuff, but not some of the "groups" of instructions. --HG-- extra : convert_revision : 4725c34f3d73971ae1763611685c5877b6c51412
2007-08-26X86: Make the Ruflag microop work correctly, and make the code a little clearer.Gabe Black

2007-08-26X86: Return values for some cpuid functions that match what my development ↵Gabe Black
machine returns. --HG-- extra : convert_revision : e6619da11f43bbe025ceabd06387dd24e1cd883b
2007-08-26X86: Make the microassembler accept lines which are just labels.Gabe Black
The labels on these lines will be associated with whatever the next microop is. --HG-- extra : convert_revision : 80c260e48ec1c16e6325061608e37c95a0610cfa
2007-08-26X86: Make cpuid actually consider the eax parameter and return different values.Gabe Black
--HG-- extra : convert_revision : 527c1cacdd20ab162859bba7f9a6bed33afa2d4f
2007-08-26X86: Fix the sign extension microop so it extends zeros correctly.Gabe Black

--HG-- extra : convert_revision : 0d6b783b2246b8ad8d91e4c63e407307ee11c651
2007-08-26X86: Make shift instructions set some of the flags they're supposed to.Gabe Black
The flag mechanism for microops needs to be fleshd out a little more to allow for custom flag calculation methods for certain microops. Shift is an example where the rules for calculating OF and CF are unique. --HG-- extra : convert_revision : 91981a00c1efd05db702fffa9cea51f912583013
2007-08-26X86: Remove x86 code that attempted to fix misaligned accesses.Gabe Black
--HG-- extra : convert_revision : 42f68010e6498aceb7ed25da278093e99150e4df
2007-08-07X86: Implemented and hooked in SCAS (scan string)Gabe Black
Fixed the asz assembler symbol. Adjusted the condion checks to have appropriate options. Implemented the SCAS microcode. Attached SCAS into the decoder. --HG-- extra : convert_revision : 17bf9ddae6bc2069e43b076f8f83c4e54fb7966c
2007-08-07X86: Add a format to handle string instructions which can use the repe and ↵Gabe Black

--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: Make fixed register operands ignore register index extensions from the ↵Gabe Black
REX prefix. The only cases where this was the correct behavior are now handled with the "B" operand type, and doing things this way was breaking some instructions, notably a shift. --HG-- extra : convert_revision : 072346d4f541edaceba7aecc26ba8d2cd756e481
2007-08-04X86: Implement the cmpxchg instruction.Gabe Black

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
