Changed the encoding of X86 floating point stack operations where both operands
...
are st(0). These can be encoded using an opcode for storing in st(0) or using
an opcode for storing in st(i), where i can also be 0. To allow testing with
the darwin assembler and get a matching binary the opcode for storing in st(0)
is now used. To do this the same logical trick is use from the darwin assembler
in converting things like this:
fmul %st(0), %st
into this:
fmul %st(0)
by looking for the second operand being X86::ST0 for specific floating point
mnemonics then removing the second X86::ST0 operand. This also has the add
benefit to allow things like:
fmul %st(1), %st
that llvm-mc did not assemble.

MC/X86: Add "support" for matching ATT style mnemonic prefixes.
...
- The idea is that when a match fails, we just try to match each of +'b', +'w',
+'l'. If exactly one matches, we assume this is a mnemonic prefix and accept
it. If all match, we assume it is width generic, and take the 'l' form.
- This would be a horrible hack, if it weren't so simple. Therefore it is an
elegant solution! Chris gets the credit for this particular elegant
solution. :)
- Next step to making this more robust is to have the X86 matcher generate the
mnemonic prefix information. Ideally we would also compute up-front exactly
which mnemonic to attempt to match, but this may require more custom code in
the matcher than is really worth it.

Replace this file containing 4 tests of x86 32-bit encodings with a file

containing the subset of the full auto generated test case that currently
encodes correctly. Again it is useful as we bring up the the new encoder

fix X86 encoder to output [disp] only addresses with no SIB byte

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. And finally marked the rep versions of
move/store string records in X86InstrInfo.td as isCodeGenOnly = 1 so tblgen is
happy building the disassembler files.
