Rafael Espindola d7565c3a06 Use a relocation against the symbol if it is a PLT and the symbol is in another 
section. Common because of linkonce sections.

Chris Lattner 13111b08fb Replace a gross hack (the MOV64ri_alt instruction) with a slightly less 
gross hack (having the asmmatcher handle the alias).

Jan Wen Voung 87f77b5f9a Add hook in MCSection to decide when to use "optimized nops", for each 
section kind. Previously, optimized nops were only used for MachO.
Also added tests for ELF and COFF.

Chris Lattner d3593c3a8e the immediate field of pshufw is actually an 8-bit field, not a 8-bit field that is sign extended. This fixes PR8288 
llvm-svn: 115473
 2010-10-03 19:09:13 +00:00
Chris Lattner b44b202d66 add support for the prefetch/prefetchw instructions, move femms into 
the right file.  The assembler supports all the 3dnow instructions now,
but not the "3dnowa" ones.

llvm-svn: 115468
 2010-10-03 18:42:30 +00:00
Chris Lattner 3a0a620c2e what the heck, add support for the rest of the 3dNow! binary operations. 
llvm-svn: 115467
 2010-10-03 18:24:18 +00:00
Chris Lattner 45270db916 Implement support for the bizarre 3DNow! encoding (which is unlike anything 
else in X86), and add support for pavgusb.  This is apparently the
only instruction (other than movsx) that is preventing ffmpeg from building
with clang.

If someone else is interested in banging out the rest of the 3DNow! 
instructions, it should be quite easy now.

Chris Lattner 4756bbeba0 fix a regression introduced in r115243, in which the instruction 
backing int_x86_ssse3_pshuf_w got removed.  This caused PR8280.

Rafael Espindola f987d5ea1c Factor some logic into ShouldRelocOnSymbol. This simplifies the code and 
fixes some cases where we were producing relocations with at symbol that
should use a section instead.

Jan Wen Voung efbdbe5565 Move logic of determining ELF entsize from the .s printer to initialization 
time. That way, the EntrySize field is initialized for other code paths, 
namely, the .ll -> .o code path.

Rafael Espindola 70d6e0e0ff Correctly produce R_X86_64_32 or R_X86_64_32S. 
With this patch in

movq    $foo, foo(%rip)
foo:
.long   foo

We produce a R_X86_64_32S for the first relocation and R_X86_64_32 for the
second one.
