5a696fb3ca "sldt <mem>" is ambiguous in 64-bit mode, but should 
always be disambiguated as sldtw.  sldtw and sldtq with
a mem operands have the same effect, but sldtw is more
compact.  Force it to sldtw, resolving rdar://8017530

6ecbbff857 fix the operand constraints of the immediate form of in/out,

b96b0c40d3 MC/X86: Tweak imul recognition, previous hack only applies for the imul form 
taking immediates.

bd6901864b MC/AsmParser: Change ParseExpression to use ParseIdentifier(), to support 
dollars in identifiers.

75e77b0063 MC/X86: Warn on scale factors > 1 without index register, instead of erroring, 
for 'as' compatibility.

7859dfd71b MC/Parser: Accept leading dollar signs in identifiers. 
- Implemented by manually splicing the tokens. If this turns out to be
   problematically platform specific, a more elegant solution would be to
   implement some context dependent lexing support.

115fdde871 fix rdar://7997827 - Accept and ignore LL and ULL suffixes on integer literals. 
Also fix 0b010 syntax to actually work while we're at it :-)

call and jumps.

4f45de1b1e MC/X86/AsmParser: Give an explicit error message when we reject an instruction 
because it could have an ambiguous suffix.

bc7c0a60da MC/ARM: Add basic support for handling predication by parsing it out of the mnemonic into a separate operand form.

parentheses from argument lists.

b95f7b12b6 tests: Mark MC/AsmParser tests as requiring x86 for now -- almost all of them 
rely on using a specific x86 triple to test what they want to test.

 2010-07-23 00:54:35 +00:00
Bruno Cardoso Lopes
7722724eee Add remaining AVX instructions (most of them dealing with GR64 destinations. This complete the assembler support for the general AVX ISA. But we still miss instructions from FMA3 and CLMUL specific feature flags, which are now the next step 
llvm-svn: 109168

5920e38cd2 Add more 256-bit forms for a bunch of regular AVX instructions 
Add 64-bit (GR64) versions of some instructions (which are not
described in their SSE forms, but are described in AVX)

llvm-svn: 109063
 2010-07-21 23:53:50 +00:00

eea3b7ed83 Add missing AVX convert instructions. Those instructions are not described in their SSE forms (although they exist), but add the AVX forms anyway, so the assembler can benefit from it

1dd74c37c5 X86: Mark JMP{32,64}[mr] as requires 32-bit/64-bit mode. They are the same 
instruction, we only want to allow the one for the current subtarget.
 - This also fixes suffix matching for jmp instructions, because it eliminates
   the ambiguity between 'jmpl' and 'jmpq'.

support macros.
