2007-08-07X86: Added some missing parenthesis in the condition code calculation function.Gabe Black
--HG-- extra : convert_revision : 663021070a4bcc795bb44e1839b8bcec686a42f0
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
2007-08-07X86: Overhaul of ruflags to get it to work correctly.Gabe Black
--HG-- extra : convert_revision : 00a36a80a1945806aac9fa7d9d6a3906465dcad2
2007-08-07X86: Make a microcode branch microop.Gabe Black
Also some touch up for ruflag. --HG-- extra : convert_revision : 829947169af25ca6573f53b9430707101c75cc23
2007-08-04X86: Implement microops and instructions that manipulate the flags register.Gabe Black
--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
--HG-- extra : convert_revision : 2dc81345176d1de247a567d1f748e2b2bd05f829
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: Implement the cmpxchg instruction.Gabe Black
--HG-- extra : convert_revision : b9e172bcb9551edf65c63f26dfa07d771edf3e1e
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: Get rid of some debug warnings.Gabe Black
Get rid of some warnings that were accidentally committed. --HG-- extra : convert_revision : e800dbce253f6ba759932ca47d64bf98129e4177
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
2007-08-02X86: Fix special case with SIB index register and REX prefix.Gabe Black
--HG-- extra : convert_revision : b305708a722f2a08cb55c4548c5616fcbe6c5d68
2007-08-01Fix how the "cmd" parameter is set in se.py and remove hack in x86 process ↵Gabe Black
initialization code. --HG-- extra : convert_revision : 1fc741eea956ebfa4cef488eef4333d1f50617a6
2007-08-01X86: Hide the irrelevant portions of the address components for load and ↵Gabe Black
store microops. --HG-- extra : convert_revision : a5ac6fefa09882f0833537e23f1ac0477bc89bb9
2007-08-01X86: Fix for compilation bug with new cache code.Gabe Black
--HG-- extra : convert_revision : 073c6db0796cd2c11b8293b382b438a2a959b821
2007-08-01X86: Get rid of initialization of R11Gabe Black
R11 is just junk after the start of exectuion because we're "returning" from an execve call and linux destroys the contents of rcx and r11 on system calls. --HG-- extra : convert_revision : 6bf69a50ce56e0355dfdd41524163874340beec0
2007-07-31Add a flag to indicate an instruction triggers a syscall in SE mode.Gabe Black
--HG-- extra : convert_revision : 1d0b3afdd8254f5b2fb4bbff1fa4a0536f78bb06
2007-07-31X86: Add operand type information to the fnstcw and fldw instruction ↵Gabe Black
placeholders. These are the only floating point instructions that get used in my simple hello world test. These instructions are for setting up the floating point control register. Their not being implemented doesn't affect anything because floating point isn't used. --HG-- extra : convert_revision : 4dfb9ef2a5665f034946c504978029e8799e64cd
2007-07-30X86: Add decoding for x87 floating point.Gabe Black
--HG-- extra : convert_revision : 08f0f4a3d77a2c5eb9b5ca0cae7d0be9a72febec
2007-07-30X86: Attach the "DIV" instruction implementation to the decoder.Gabe Black
--HG-- extra : convert_revision : 8aef1c8d1ced2db998ed0d31241cadc17e19eadd
2007-07-30X86: Remove a naming conflict between the register index parameters and the ↵Gabe Black
"picked" register values. --HG-- extra : convert_revision : 7b2c1be509478153ebf396841e4cbeccee3e03d1
2007-07-30X86: __pad0 should be a 4 byte pad, not a 4 long array of 4 byte pads.Gabe Black
--HG-- extra : convert_revision : e0d5ab617bc95d5d714fa9fcdf0a448874aef886
2007-07-30X86: Turn on the exit_group, exit, munmap, and write syscalls.Gabe Black

2007-07-30X86: Implement unsigned divide. The non-byte version ignores rdx which it ↵Gabe Black

2007-07-30X86: Allow RIP relative decode on -all- memory forms of operands.Gabe Black

2007-07-30X86: Fix up the stat structure. This probably still isn't right.Gabe Black
--HG-- extra : convert_revision : 2e2a22cdf3abe648c9e1309b9070cfd10fc4a8b8
2007-07-30X86: Hook in the new instructions.Gabe Black

--HG-- extra : convert_revision : 9c4802f6c6e4eaab36aac900e2c7576682cb0f33
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

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
