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

Implement enough of the missing instalias support to get aliases installed and working. They now work when the matched pattern and the result instruction have exactly the same operand list. This is now enough for us to define proper aliases for movzx and movsx, implementing rdar://8017633 and PR7459. Note that we do not accept instructions like: movzx 0(%rsp), %rsi GAS accepts this instruction, but it doesn't make any sense because we don't know the size of the memory operand. It could be 8/16/32 bits. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117901 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 aliases for movs between seg registers and mem. There are multiple different forms of this instruction (movw/movl/movq) which we reported as being ambiguous. Since they all do the same thing, gas just picks the one with the shortest encoding. Follow its lead here.
