Chris Lattner 88c185617c have the mc lowering process handle a few tail call forms, lowering them to 
jumps where possible and turning the TAILCALL marker in the instruction
asm string into a proper comment.

This eliminates a FIXME and is on the path to finishing:
rdar://7639610 - eliminate encoding and asm info for TAILJMPd TAILJMPr TAILJMPn, etc.

However, I can't eliminate the encodings for these instructions because the JIT
still exists and has its own copy of the encoder, sigh.

Chris Lattner ac5881295c Implement the major chunk of PR7195: support for 'callw' 
in the integrated assembler.  Still some discussion to be
done.

Daniel Dunbar 7c8bd0fc98 MC: Change RelaxInstruction to only take the input and output instructions. 
llvm-svn: 104713
 2010-05-26 18:15:06 +00:00
Daniel Dunbar a19838e107 MC: Simplify MayNeedRelaxation to not provide the fixups, so we can query it 
before encoding.

Daniel Dunbar b34440a6a8 MC: Eliminate MCAsmFixup, replace with MCFixup.

Daniel Dunbar 353a91ff76 MC: Use accessors for access to MCAsmFixup.

Matt Fleming 5abb6dd61e Split out the x86_32 an x86_64 ELF backends as they handle ELF 
differently. This will make adding ELF support easier in the long run.

Daniel Dunbar 52e37becf6 MC/X86: Add missing entry for TAILJMP_1 to getRelaxedOpcode().

Eric Christopher bf79238599 Add some section and constant support for darwin TLS.

Daniel Dunbar ba2f4c3884 MC/Mach-O/x86_64: Add a new hook for checking whether a particular section can 
be diced into atoms, and adjust getAtom() to take this into account.
 - This fixes relocations to symbols in fixed size literal sections, for
   example.

Daniel Dunbar 358b29c855 MC/X86: Error out if we see a non-constant FK_Data_1 or FK_Data_2 fixup, since 
we don't currently support relaxing them.

Daniel Dunbar 86face8333 MC: Add TargetAsmBackend::MayNeedRelaxation, for checking whether a particular instruction + fixups might need relaxation. 
llvm-svn: 99249

Daniel Dunbar a9ae3ae698 MC: Add TargetAsmBackend::WriteNopData and use to eliminate some target dependencies in MCMachOStreamer and MCAssembler.

Daniel Dunbar e0c43577c1 MC: Add TargetAsmBackend::RelaxInstruction callback, and custom X86 implementation. 
llvm-svn: 99245
 2010-03-23 01:39:09 +00:00
Daniel Dunbar 4d7c8645fd MC: Add TargetAsmBackend::createObjectWriter. 
- MCAssembler is now object-file independent, although we will surely need more work to fully support ELF/COFF.

Daniel Dunbar c5084cccc8 MC: Add TargetAsmBackend::isVirtualSection hook. 
llvm-svn: 98950
 2010-03-19 09:29:03 +00:00
Daniel Dunbar f0517efc6c MCAssembler: Move ApplyFixup to the TargetAsmBackend, this is a target specific not object writer specific task. 
llvm-svn: 98947
 2010-03-19 09:28:12 +00:00
Daniel Dunbar 6544baff6f MC/Darwin: Add a new target hook for whether the target uses "reliable" symbol differences, basically whether the assembler should attempt to understand atoms when using scattered symbols. 
Also, avoid some virtual call overhead.

Daniel Dunbar fe8d866fc7 MC/Mach-O/x86_64: Temporary labels in cstring sections require symbols (and external relocations, but we don't have x86_64 relocations yet). 
llvm-svn: 98583
 2010-03-15 21:56:50 +00:00
Daniel Dunbar 77c4141c8f MC: Sketch some TargetAsmBackend hooks we are going to need.

Daniel Dunbar 245f5b2810 MC: Provide the target triple to AsmBackend constructors. 
llvm-svn: 98220
