4c6357d4af Add X86 BEXTR instruction. This instruction uses VEX.vvvv to encode Operand 3 instead of Operand 2 so needs special casing in the disassembler and code emitter. Ultimately, should pass this information from tablegen 
llvm-svn: 142105
 2011-10-16 03:51:13 +00:00
Craig Topper
62e63d9bb9 Add support for X86 blsr, blsmsk, and blsi instructions. Required extra work because these are the first VEX encoded instructions to use the reg field as an opcode extension.

4456c94f70 Treat VEX.vvvv as a 3-bit field outside of 64-bit mode. Prevents access to registers xmm8-xmm15 outside 64-bit mode.

99ad3cc23e Fix disassembler handling of CRC32 which is an odd instruction that uses 0xf2 as an opcode extension and allows the opsize prefix. This necessitated adding IC_XD_OPSIZE and IC_64BIT_XD_OPSIZE contexts. Unfortunately, this increases the size of the disassembler tables. Fixes PR10702.

90a1526592 Change X86 disassembly to print immediates values as signed by default. Special 
case those instructions that the immediate is not sign-extend.  radr://8795217

316c7bfe37 Make IC_VEX* not inherit from IC_*. Prevents instructions with no VEX form from disassembling to their non-VEX form. Also prevents weak filter collisons that were keeping valid VEX instructions from decoding properly. Make VEX_L* not inherit from VEX_* because the VEX.L bit always important. This stops packed int VEX encodings from being disassembled when specified with VEX.L=1. Fixes PR10831 and PR10806.

e78b505311 Basic sanity checks to ensure that 2- and 3-byte 
VEX prefixes are working for triadic AVX
instructions.  This concludes the patch set to
enable AVX support for the X86 disassebler.
