Chris Lattner a3a66b28b6 add a special relocation type for movq loads for object
files that produce special relocation types where the 
linker changes movq's into lea's.

Daniel Dunbar b86672059e MC/X86: Add an XFAIL test where we aren't matching the correct instruction
because we don't understand how the specific instruction is doing sign
extension.

Daniel Dunbar b70c2f795e MC/X86: Rename alternate spellings of ADD{8,16,32} and mark as "code gen only" so they don't get selected by the asm matcher.

Daniel Dunbar d0c6d361fe MC/AsmParser: Attempt to constant fold expressions up-front. This ensures we avoid fixups for obvious cases like '-(16)'.

Chris Lattner 509154e0f9 rip out the 'heinous' x86 MCCodeEmitter implementation.
We still have the templated X86 JIT emitter, *and* the
almost-copy in X86InstrInfo for getting instruction sizes.

Chris Lattner 1572e760bc fix the encodings of monitor and mwait, which were completely
busted in both encoders.  I'm not bothering to fix it in the
old one at this point.

Kevin Enderby cfd0e5a15e Update the X86 assembler matcher test case now that a few more things match
with some of the recent changes that have gone into llvm-mc.

Daniel Dunbar 3e0c9790f2 MC/X86 AsmMatcher: Fix a use after free spotted by d0k, and de-XFAIL
x86_32-encoding.s in on expectation of it passing.

Kevin Enderby cc152d6159 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
to make sure currently working stuff stays working.

Kevin Enderby a7c1d6cfd1 Fix the encoding of the movntdqa X86 instruction. It was missing the 0x66
prefix which is part of the opcode encoding.

Chris Lattner 0c3b66cd87 fix X86 encoder to output [disp] only addresses with no SIB byte
in X86-32 mode.  This is still required in x86-64 mode to avoid
forming [disp+rip] encoding.  Rewrite the SIB byte decision logic
to be actually understandable.

Chris Lattner d91f302a05 fix a case where we'd mis-encode fisttp because of an incorrect (and
redundant with a correct one) pattern that was added for the disassembler.

Kevin Enderby 00f1e6c030 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.

Daniel Dunbar bdbffbedf0 AsmParser/X86: Add temporary hack to allow parsing "sal". Eventually we need
some mechanism for specifying alternative syntaxes, but I'm not sure what form
that should take yet.

Chris Lattner 73051044fd remove the # TAILCALL markers, which was causing the to fail.
It's unclear if the matcher is nondeterminstic of what here,
but I'm getting matches without TAILCALL and some other hosts
are getting matches with it.

2010-02-02 22:36:29 +00:00
Chris Lattner de9b3ada5d this apparently depends on the host somehow.

Chris Lattner 2481509162 disable this test for now.

Kevin Enderby db32c4567b Added another version of the X86 assembler matcher test case.
This test case is different subset of the full auto generated test case, and a
larger subset that is in x86_32-bit.s (that set will encode correctly).  These
instructions can pass though llvm-mc as it were a logical cat(1) and then
reassemble to the same instruction.  It is useful as we bring up the parser and
matcher so we don't break things that currently work.

Daniel Dunbar 76e5d70c57 MC/X86 AsmParser: Handle absolute memory operands correctly. We were doing
something totally broken and parsing them as immediates, but the .td file also
had the wrong match class so things sortof worked. Except, that is, that we
would parse
  movl $0, %eax
as
  movl 0, %eax
Feel free to guess how well that worked.

Daniel Dunbar 7f0421eebb MC/X86: Add a nice X86 assembler matcher test case from Kevin Enderby.
- This test case is auto generated, and has been verified to round-trip
   correctly through llvm-mc by checking the assembled .o file before and after
   piping through llvm-mc. It will be extended over time as the matcher grows
   support for more instructions.

run if appropriate target is supported.
