Jim Grosbach 3322f02a03 Tidy up. Whitespace. 
llvm-svn: 138207

Jim Grosbach 38b1ed8ce2 Move some ELF directives into ELF asm parser. 
The .local, .hidden, .internal, and .protected are not legal for all supported
file formats (in particular, they're invalid for MachO). Move the parsing for
them into the ELF assembly parser since that's the format they're for.
Similarly, .weak is used by COFF and ELF, but not MachO, so move the parsing
to the COFF and ELF asm parsers. Previously, using any of these directives
on Darwin would result in an assertion failure in the parser; now we get
a diagnostic as we should.

Jim Grosbach 76346c3bf7 Asm parser range checking on .<size> <value> directives. 
For example, ".byte 256" would previously assert() when emitting an object
file. Now it generates a diagnostic that the literal value is out of range.

Charles Davis 567a1ad7c5 Add a test for the chained directives that I forgot last time. 
llvm-svn: 132110
 2011-05-26 05:17:43 +00:00
Charles Davis 006e1c39d0 Test .seh_startchained and .seh_endchained parsing. 
Rework how the MCWin64EHUnwindInfo instances are stored. Fix issues with
chained unwind areas exposed by the test that were related to this.

The ChainedParent field had the wrong address, because when the chained unwind
info was added, the addresses shifted around. Now we store the pointers to the
structures, which are now allocated from the MC heap.

llvm-svn: 132106
 2011-05-26 02:45:47 +00:00
Charles Davis 2f6ecea19d Add tests for .seh_setframe and .seh_handlerdata parsing. Fix issues with 
them.

I had to add a special SwitchSectionNoChange method to MCStreamer just for
.seh_handlerdata. If this isn't OK, please let me know, and I'll find some
other way to fix .seh_handlerdata streaming.

one I found by inspection).

llvm-svn: 132037
 2011-05-25 04:08:15 +00:00
Charles Davis fc1e7ce850 Add a test for the .seh_handler directive. Fix problems with the parsing 
method exposed by the test. While we're at it, simplify the .seh_proc
parsing method.

 2011-02-23 21:43:31 +00:00
Jim Grosbach 0c03a3a146 Revert r125595, which is an X86-only undocumented assembly syntax extension 
enabled for all targets. Non-X86 targets should not have this behavior
enabled by default.

Joerg, if you would like to resubmit with the behavior conditionalized to be
X86-ELF only, that's fine.

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'

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.

notes:
- The instructions are being added with dummy placeholder patterns using some 256
  specifiers, this is not meant to work now, but since there are some multiclasses
  generic enough to accept them,  when we go for codegen, the stuff will be already
  there.
- Add VEX encoding bits to support YMM
- Add MOVUPS and MOVAPS in the first round
- Use "Y" as suffix for those Instructions: MOVUPSYrr, ...
- All AVX instructions in X86InstrSSE.td will move soon to a new X86InstrAVX
  file.
