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

--HG-- extra : convert_revision : c551f51cdda46df99370363ed2d70916db8413eb
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 : 9d7ca286ba7709175fa75226320601acce4ced98

--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
2007-08-26Address translation: Make the page table more flexible.Gabe Black
The page table now stores actual page table entries. It is still a templated class here, but this will be corrected in the near future. --HG-- extra : convert_revision : 804dcc6320414c2b3ab76a74a15295bd24e1d13d
2007-08-26X86: Remove x86 code that attempted to fix misaligned accesses.Gabe Black
--HG-- extra : convert_revision : 42f68010e6498aceb7ed25da278093e99150e4df
2007-08-26Address Translation: Make SE mode use an actual TLB/MMU for translation like FS.Gabe Black
--HG-- extra : convert_revision : a04a30df0b6246e877a1cea35420dbac94b506b1
2007-08-26SPARC: Make sure unaligned access are caught on cached translations as well.Gabe Black
--HG-- extra : convert_revision : 5c1f3f585817a19a771164f809dfc2fdc1ab3fb2
2007-08-13SPARC: Make nops have the IsNop flag set.Gabe Black
In O3, a nop is used to carry faults down the pipeline that didn't originate from an instruction. If the instruction doesn't do anything, that is just returns NoFault, but doesn't have IsNop set, the NoFault will overwrite the fault that's being sent down and nothing will happen. --HG-- extra : convert_revision : 54d99002b550ca0e1cf14603f588dc1038e3e535
2007-08-13SPARC: Move tlb state into the tlb.Gabe Black
Each "strand" may need to have a private copy of this state, but I couldn't find anywhere in the spec that said that after looking briefly. This prevents writes to the thread context in o3 which was causing the pipeline to be flushed and stopping any forward progress. The other ASI accessible state will probably need to be accessed differently if/when we get O3 full system up and running. --HG-- extra : convert_revision : fa7fba812d7f76564ef4a23818e60f536710d557
2007-08-13SPARC: Make the spill and fill handlers use the correct ASI, and let ↵Gabe Black

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
repne prefixes. --HG-- extra : convert_revision : 205fbbb947258bc0ef2915e22d5b32a3df1a1ce2

--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 the open flags correct.Gabe Black

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: 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
2007-08-04X86: Create a base enum value for indexing into a region of the miscregs.Gabe Black
This lets you index into a group of registers without having to know explicitly which one is the lowest in that group. --HG-- extra : convert_revision : e3cad25a1c5910955204c37177b049ca9834cfd9
2007-08-04X86: Add the arch_prctl system call and fix up some microcoding.Gabe Black
The arch_prctl system call is used to set and get the FS and GS segment bases. The FS segment is use for TLS, so glibc needs to be able to set it up. --HG-- extra : convert_revision : 79501491a15967a7a862add846ff88a934fb1b37

2007-08-02X86: Finally get the x86 initial stack frame right.Gabe Black
After very carefully reading through the Linux source, I'm pretty confident I now know -exactly- how the initial stack frame is constructed, filled, and aligned. --HG-- extra : convert_revision : 3c654ade7e458bdd5445026860f11175f383a65f
