2009-01-06X86: Hook in the M5 pseudo insts.Gabe Black
2008-10-12X86: Implement CPUID with a magical function instead of microcode.Gabe Black

2007-10-02X86: Distinguish between the rep and repe prefixes.Gabe Black
STOS and MOVS only accept the rep prefix which always loops until rcx becomes 0. The other string instructions accept repe (same encoding as rep) and repne which also check the condition code flags each iteration. --HG-- extra : convert_revision : 544149f640302070810fb53e53bfeb0e87160ffc
2007-08-07X86: Add a format to handle string instructions which can use the repe and ↵Gabe Black
repne prefixes. --HG-- extra : convert_revision : 205fbbb947258bc0ef2915e22d5b32a3df1a1ce2

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

2007-06-14Implement a handful more instructions and differentiate macroops based on ↵Gabe Black
the operand types they expect. --HG-- extra : convert_revision : f9c8e694a8c0eb33b988657dca03ab495b65bee8

src/arch/x86/isa/formats/multi.isa: Make the formats use objects to pass around output code. --HG-- extra : convert_revision : 428915bda22e848befac15097f56375c1818426e

--HG-- extra : convert_revision : def1a30e54b59c718c451a631a1be6f8e787e843
2007-04-06Refactored 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
2007-04-06Clean up the macroop code.Gabe Black
--HG-- extra : convert_revision : 3cf83c3e038fece6190dbb91f56deb0498c9a70d
2007-04-04Reworking 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
2007-04-03A batch of changes and fixes. Macroops are now generated automatically, ↵Gabe Black
multiops do alot more of what they're supposed to (excluding memory operands), and microops are slightly more implemented. --HG-- extra : convert_revision : 518059f47e11df50aa450d4a322ef2ac069c99c9
2007-03-29Made the MultiOp format do a little more. It now sets up single microop ↵Gabe Black
instructions to return an instance of the right class. The code to decode register numbers and generate loads and stores still needs to be added. Also, a syntax for specifying operands as sources, destinations, or both needs to be established. Multipl microop instructions are also not handled, pending real macroop generation support. --HG-- extra : convert_revision : 1a0a4b36afce8255e23e3cdd7a85c1392dda5f72
2007-03-21Start implementing groups of instructions which do the same thing on ↵Gabe Black
different sets of inputs. --HG-- extra : convert_revision : 6a5be61831588f801965dd4e80cb52f28911c320
2007-03-21Break 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
2007-03-15Make the predecoder an object with it's own switched header file. Start ↵Gabe Black
