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

2007-07-17Make disassembled x86 register indices reflect their size.Gabe Black
This doesn't handle high byte register accesses. It also highlights the fact that address size isn't actually being calculated, and that the size a microop uses needs to be overridable from the microassembly. --HG-- extra : convert_revision : d495ac4f5756dc55a5f71953ff6963b3c030e6cb
2007-07-17Implemented jnz.Gabe Black

2007-07-17Make "test" set some condition codes.Gabe Black
It still needs to zero the overflow and carry flags to be correct. --HG-- extra : convert_revision : 73cb3a55f7b4234389d9355f5ad45da6aaaa6c60
2007-07-17Add in support for condition code flags.Gabe Black
Some microops can set the condition codes, and some of them can be predicated on them. Some of the codes aren't implemented because it was unclear from the AMD patent what they actually did. They are used with string instructions, but they use variables IP, DTF, and SSTF which don't appear to be documented. --HG-- extra : convert_revision : 2236cccd07d0091762b50148975f301bb1d2da3f
2007-07-17Add in operand which holds the condition code bits of the flag register.Gabe Black

could check. --HG-- extra : convert_revision : 1f542b8aadfd5146539cadef631b49d77f578472
