--HG-- extra : convert_revision : 1cf4d998699d131c3b20eef67a3c2817af0ce439
2007-07-29X86: Make logic instructions flag setting work.Gabe Black
The instructions now ask for the appropriate flags to be set, and the microops do the "right thing" with the CF and OF flags, namely zero them. --HG-- extra : convert_revision : 85138a832f44c879bf8a11bd3a35b58be6272ef3
2007-07-29X86: Make arithmetic instructions set the appropriate flags.Gabe Black
--HG-- extra : convert_revision : 3bdef3876c7b86bc93365edee876b74a201d625f
2007-07-29BsaeCPU: Get rid of some bad DPRINTFs.Steve Reinhardt
People should never put pointers in DPRINTFs; it messes up tracediffs. Plus these used the FullCPU trace flag, which is not right. --HG-- extra : convert_revision : 82ed56757da0ad947c165ba205b5f752c85c6667
2007-07-29X86: Initial stack frame fixes and constant shuffling.Gabe Black
The initial stack frame for x86 is now substantially more correct. The fixes made here can be back ported to SPARC and possible the other ISAs as well. The auxiliary vector types were moved to the LiveProcess base class because they are independent of ISA. Some of the types may only apply to Linux, though, so they may have to be moved. --HG-- extra : convert_revision : 89ace35fcc8eb9586d2fee8eeccbc3686499ef24
2007-07-29X86: Make limm use merge and allow overriding the data size.Gabe Black
--HG-- extra : convert_revision : c6057226b8ff8f272612a9d3bf7d1d9ba90c819b
2007-07-29X86: Fix register ordering.Gabe Black
The correct order is unintuitively rax, rcx, rdx, rbx, etc, not rax, rbx, rcx, rdx. --HG-- extra : convert_revision : 3abe6a723a6e30becfe34f8da707ea2ff5d4df77
2007-07-29X86: return -return_value.value() on failure.Gabe Black
--HG-- extra : convert_revision : d8e1486ff075b2917be62a0008f83fd6c9e4c09a
2007-07-29X86: Fix popa and push with the stack pointer.Gabe Black
POPA used st instead of ld, and it didn't skip rsp. push rsp needs to store the -original- value of the stack pointer. --HG-- extra : convert_revision : 376370c99b6ab60fb2bc4cd4f0a6dce71153ad06
2007-07-29X86: Fix a bug with mergeGabe Black
Merge was returning the value to merge in, not the actual result of the merge. --HG-- extra : convert_revision : 230b4b5064037d099ae7859edabdf5be84603849
2007-07-28X86: Fix a comment and adjust the stack base address.Gabe Black
The stack base on my development machine starts one page below where it needs to. I don't know why it does, but I've duplicated it in m5. --HG-- extra : convert_revision : c4783ba885b90f17e843f61e07af0bc3330a74bc

2007-07-28X86: Fix up auxiliary vectors.Gabe Black
The type constants should go into an architecture independent spot since they are universal to all Linux elf binaries. The right value for some of the vectors needs to be determined. Also, x86 does not store argc or argv_array_base in registers like some other architectures. --HG-- extra : convert_revision : 8d3f6a3e028d881d3c41e8ddf4f29d25738b529c
2007-07-28Turn the instruction tracing code into pluggable sim objects.Gabe Black
These need to be refined a little still and given parameters. --HG-- extra : convert_revision : 9a8f5a7bd9dacbebbbd2c235cd890c49a81040d7

2007-07-26X86: Fix argument register indexing.Gabe Black
Code was assuming that all argument registers followed in order from ArgumentReg0. There is now an ArgumentReg array which is indexed to find the right index. There is a constant, NumArgumentRegs, which can be used to protect against using an invalid ArgumentReg. --HG-- extra : convert_revision : f448a3ca4d6adc3fc3323562870f70eec05a8a1f
2007-07-26X86: Hook in shift and rotate by one instructions, and NOT.Gabe Black

2007-07-26X86: Add functions to read and write to an exec context.Gabe Black
These functions take care of calling the thread contexts read and write functions with the right sized data type, and handle unaligned accesses. --HG-- extra : convert_revision : b4b59ab2b22559333035185946bae3eab316c879
2007-07-26X86: Fix carry calculation for subtraction based microops.Gabe Black
The carry flag should be calculated using the -complement- of the second operand, not it's negation. The carry in which is part of computing the 2's complement may induce a carry, but if you've already caused the carry before you get the carry computing logic involved, it will miss it. --HG-- extra : convert_revision : 318cf86929664fc52ed9e023606a9e892eba635c
2007-07-26Add functions for mmap and brk.Gabe Black
