llvm-svn: 115021

Chris Lattner f60062fd55 add basic avx support to the disassembler, also teach it about ssmem/sdmem 
operands.

With this done, we can remove the _Int suffixes from the round instructions
without the disassembler blowing up.  This allows the assembler to support
them, implementing rdar://8456376 - llvm-mc rejects 'roundss'

llvm-svn: 115019
 2010-09-29 02:57:56 +00:00

llvm-svn: 115015
 2010-09-29 01:50:45 +00:00
Daniel Dunbar d116d8a4e9 MC/AsmParser: Handle exponents in floating point literals.

llvm-svn: 114819
 2010-09-27 07:11:53 +00:00
Chris Lattner ff0062af62 Fix rdar://8468087 - llvm-mc commutes fmul (and friend) operands. 
My previous fix for rdar://8456371 should only apply to fmulp/faddp,
not to fmul/fadd.  Instruction set orthogonality is overrated or 
something.

llvm-svn: 114818
 2010-09-27 07:08:21 +00:00
Chris Lattner 4f59cbfb66 implement support for 'clr' alias. This is part of rdar://8416805, 
but balrog was wanting it on irc.

llvm-svn: 114809
 2010-09-27 04:23:03 +00:00
Daniel Dunbar ce17f72c38 MC/AsmParser: Handle a missed case of floating literals in the lexer. 
llvm-svn: 114733
 2010-09-24 17:10:26 +00:00
Daniel Dunbar 2af1653032 MC/AsmParser: Support .single and .double for embedding floating point literals. 
- I believe more modern 'gas' supports a more enhanced set of arithmetic on
   them, but for now the only thing we can do is emit them as data.

llvm-svn: 114719
 2010-09-24 01:59:56 +00:00
Chris Lattner 415624cf3f fix rdar://8456371 - Handle commutable instructions written backward. 
llvm-svn: 114536
 2010-09-22 06:26:39 +00:00
Chris Lattner bd85725341 Fix an inconsistency in the x86 backend that led it to reject "calll foo" on 
x86-32: 32-bit calls were named "call" not "calll".  64-bit calls were correctly
named "callq", so this only impacted x86-32.

This fixes rdar://8456370 - llvm-mc rejects 'calll'

This also exposes that mingw/64 is generating a 32-bit call instead of a 64-bit call,
I will file a bugzilla.

llvm-svn: 114534
 2010-09-22 05:49:14 +00:00

What a weird instruction.

llvm-svn: 114190
 2010-09-17 18:02:29 +00:00
Daniel Dunbar 55f16678e4 MC/AsmParser: Add support for 'a + 4@GOTPCREL' and friends, by reconsing the 
expression to include the modifier.
 - Gross, but this a corner case we don't expect to see often in practice, but
   it is worth accepting.
 - Also improves diagnostics on invalid modifiers.

llvm-svn: 114154
 2010-09-17 02:47:07 +00:00
Chris Lattner 74d320db97 fix rdar://8438816 - unrecognized 'fildq' instruction 
llvm-svn: 114116
 2010-09-16 20:46:38 +00:00
Chris Lattner ee7e6f42f8 lcall and ljmp always default to lcalll and ljmpl. This finally 
wraps up r8418316

llvm-svn: 113949
 2010-09-15 05:30:20 +00:00
Chris Lattner 09bfe645f6 apparently jmpl $1,$2 is an alias for ljmpl, similiarly 
for call.  Add this.

llvm-svn: 113948
 2010-09-15 05:25:21 +00:00
Chris Lattner 6757eae45e Disambiguate lcall/ljmp to the 32-bit version. This happens 
even in 64-bit mode apparently.

llvm-svn: 113945
 2010-09-15 05:14:54 +00:00
Chris Lattner 5be87c619b fix the encoding of sldt GR16 to have the 0x66 prefix, and

llvm-svn: 113936
 2010-09-15 04:33:27 +00:00
Chris Lattner 81ce173860 add various broken forms of fnstsw. I didn't add the %rax 
version because it adds a prefix and makes even less sense
than the other broken forms.  This wraps up rdar://8431422

llvm-svn: 113932
 2010-09-15 04:15:16 +00:00

Daniel Dunbar e5444a88cd llvm-mc: Don't crash when using -n and we see a directive before the initial section. 
- This is annoying, because we have to scatter this check everywhere that could emit real data, but I see no better solution.

llvm-svn: 113552
 2010-09-09 22:42:59 +00:00
Daniel Dunbar 43325c4a68 llvm-mc: Make sure we exit != 0 if any errors are encountered.

 2010-09-07 00:05:45 +00:00
Chris Lattner 7ece716da2 "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

Daniel Dunbar 3b96ffdac1 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.
