fix the encoding of sldt GR16 to have the 0x66 prefix, and add sldt GR32, which isn't documented in the intel manual but which gas accepts. Part of rdar://8418316 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@113938 91177308-0d34-0410-b5e6-96231b3b80d8

Update llvm-mc / MCAsmStreamer to print the instruction using the actual target specific printer (this only works on x86, for now). - This makes it possible to do some correctness checking of the parsing and matching, since we can compare the results of 'as' on the original input, to those of 'as' on the output from llvm-mc. - In theory, we could now have an easy ATT -> Intel syntax converter. :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78986 91177308-0d34-0410-b5e6-96231b3b80d8

Added support for X86 instruction prefixes so llvm-mc can assemble them. The Lock prefix, Repeat string operation prefixes and the Segment override prefixes. Also added versions of the move string and store string instructions without the repeat prefixes to X86InstrInfo.td.

Previously we didn't parse or print an 'l' suffix. cvtt*2si/cvt*2si should parse with an 'l' or 'q' suffix or not suffix at all. No suffix should use the destination register size to choose encoding.

Fix suffix handling for parsing and printing of cvtsi2ss, cvtsi2sd, cvtss2si, cvttss2si, cvtsd2si, and cvttsd2si to match gas behavior. cvtsi2* should parse with an 'l' or 'q' suffix or no suffix at all. No suffix should be treated the same as 'l' suffix. Printing should always print a suffix. Previously we didn't parse or print an 'l' suffix. cvtt*2si/cvt*2si should parse with an 'l' or 'q' suffix or not suffix at all. No suffix should use the destination register size to choose encoding. Printing should not print a suffix. Original 'l' suffix issue with cvtsi2* pointed out by Michael Kuperstein. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171668 91177308-0d34-0410-b5e6-96231b3b80d8

Added a handful of x86-32 instructions that were missing so that llvm-mc would be more complete. These are only expected to be used by llvm-mc with assembly source so there is no pattern, [], in the .td files. Most are being added to X86InstrInfo.td as Chris suggested and only comments about register uses are added. Suggestions welcome on the .td changes as I'm not sure on every detail of the x86 records. More missing instructions will be coming. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@116716 91177308-0d34-0410-b5e6-96231b3b80d8

Add assembler/disassembler support for non-AVX pclmulqdq. While I'm here, use proper aliases for the pclmullqlqdq and friends. PR10269. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134424 91177308-0d34-0410-b5e6-96231b3b80d8

Fix assembling of xchg %eax, %eax to not use the NOP encoding of 0x90. This was done by creating a new register group that excludes AX registers. Fixes PR10345. Also added aliases for flipping the order of the operands of xchg <reg>, %eax. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@141274 91177308-0d34-0410-b5e6-96231b3b80d8

Revert part of r141274. Only need to change encoding for xchg %eax, %eax in 64-bit mode. This is because in 64-bit mode xchg %eax, %eax implies zeroing the upper 32-bits of RAX which makes it not a NOP. In 32-bit mode using NOP encoding is fine. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@141353 91177308-0d34-0410-b5e6-96231b3b80d8

Change the sysexit mnemonic (and sysexitl) to never have the REX.W prefix and not depend on In32BitMode. Use the sysexitq mnemonic for the version with the REX.W prefix and only allow it only In64BitMode. rdar://9738584 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@143112 91177308-0d34-0410-b5e6-96231b3b80d8
