2009-02-27	X86: Respect segment override prefixes even when there's no ModRM byte.	Gabe Black

2009-01-06	X86: Autogenerate macroop generateDisassemble function.	Gabe Black

2009-01-06	X86: Move the macroop class out of the isa description into C++.	Gabe Black

2008-10-12	X86: Set the delayed commit flag in x86 microops appropriately.	Gabe Black

2008-10-12	X86: Make X86's microcode ROM actually do something.	Gabe Black

2007-10-18	X86: Implement the in/out instructions. These will still need support from ↵	Gabe Black
	the TLB and memory system. --HG-- extra : convert_revision : a9503248ea9efca7e5247e4f2830967f428b8215
2007-09-04	X86: Add some SSE floating point/integer conversion microops.	Gabe Black
	--HG-- extra : convert_revision : 2a1aa16709db940f5f40bbd84ca082f26b03b9c5
2007-08-31	X86: 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
2007-08-26	X86: 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
2007-08-04	X86: 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
2007-07-23	Make the operand size reflect the size specifier on the operand tags, and ↵	Gabe Black
	implement NEG --HG-- extra : convert_revision : da73ed6820d57f083c18f44b2fa868fc0976dd16
2007-06-20	Make 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
2007-06-19	Get 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
2007-06-14	Get 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
2007-06-12	Make 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
2007-06-08	Big changes to use the new microcode assembler.	Gabe Black

2007-06-04	Reworking x86's microcode system. This is a work in progress, and X86 ↵	Gabe Black

2007-04-10	Reworked x86 a bit	Gabe Black

2007-04-06	Refactored 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
