2007-04-06	Move the instruction specialization stuff out of the microassembler file, ↵	Gabe Black
	and added some comments to main.isa --HG-- extra : convert_revision : 1534ae7d5a9e95bf662d79a04f9286c227541c6c
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
2007-04-04	Reworking how x86's isa description works. I'm adopting the following ↵	Gabe Black
	definitions to make figuring out what's what a little easier: MicroOp: A single operation actually implemented in hardware. MacroOp: A collection of microops which are executed as a unit. Instruction: An architected instruction which can be implemented with a macroop or a microop. --HG-- extra : convert_revision : 1cfc8409cc686c75220767839f55a30551aa6f13
2007-03-29	Add a microcode assembler. A microcode "program" is a series of statements. ↵	Gabe Black
	Each statement has an optional label at the beginning, a capitilized microcode class name which is roughly equivalent to a mnemonic in a regular ISA, and then an optional series of operands seperated by white space. The operands are either a decimal constant, a label, or a code fragment surrounded by non nested {}s. Labels are a letter or underscore followed by letters, underscores, or digits. The syntax for describing code segments might need to be changed if a need arrises to have {}s in the code itself. --HG-- extra : convert_revision : 8e5cfdd1a3c9a7e3731fdf6acd615ee82ac2b9b7
2007-03-29	Add code to generate register and immediate based integer op microop classes.	Gabe Black

2007-03-21	Break 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
2007-03-05	Stub decoder. This is probably even farther from finished than it looks...	Gabe Black
