--HG-- extra : convert_revision : 303ea45f69f7805361ad877fe6bb43fbc3dfd7a6
2007-09-06X86: Rework the multiplication microops so that they work like they would in ↵Gabe Black

it still needed. --HG-- extra : convert_revision : 86ee0e2bf716d52c34ee731727d6366935f103ed
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

2007-07-23Implement pusha, popa, three operand imul, hook them into the decoder, and ↵Gabe Black

2007-07-23Make the operand size reflect the size specifier on the operand tags, and ↵Gabe Black
implement NEG --HG-- extra : convert_revision : da73ed6820d57f083c18f44b2fa868fc0976dd16
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

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
2007-06-08Move 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
