- On COFF the .lcomm directive has an alignment argument.
- On ELF we fall back to .local + .comm

Based on a patch by NAKAMURA Takumi.

Fixes PR9337, PR9483 and PR10128.

These are strictly utilities for registering targets and components.

The argument is unused, and is a layering violation in any case.

but it solves a layering violation since things in Support are not supposed to
use things in Transforms.

Rename TargetAsmParser to MCTargetAsmParser and TargetAsmLexer to MCTargetAsmLexer; rename createAsmLexer to createMCAsmLexer and createAsmParser to createMCAsmParser.

There is still a bit more refactoring left to do in Targets. But we are now very
close to fixing all the layering issues in MC.

TargetLoweringObjectFileImpl down to MCObjectFileInfo.

TargetAsmInfo is done to one last method. It's *almost* gone!

(including compilation, assembly). Move relocation model Reloc::Model from
TargetMachine to MCCodeGenInfo so it's accessible even without TargetMachine.

to MCRegisterInfo. Also initialize the mapping at construction time.

This patch eliminate TargetRegisterInfo from TargetAsmInfo. It's another step
towards fixing the layering violation.

Rename createAsmInfo to createMCAsmInfo and move registration code to MCTargetDesc to prepare for next round of changes.

llvm-svn: 135219

TargetAsmInfo, which in turn pulls in TargetRegisterInfo, etc. :-( There are
other cases of violations, but this is probably the worst.

This patch is but one small step towards fixing this. 500 more steps to go. :-(

CPU, and feature string. Parsing some asm directives can change
subtarget state (e.g. .code 16) and it must be reflected in other
modules (e.g. MCCodeEmitter). That is, the MCSubtargetInfo instance
must be shared.

llvm-svn: 134795

- Each target asm parser now creates its own MCSubtatgetInfo (if needed).
- Changed AssemblerPredicate to take subtarget features which tablegen uses
  to generate asm matcher subtarget feature queries. e.g.
  "ModeThumb,FeatureThumb2" is translated to
  "(Bits & ModeThumb) != 0 && (Bits & FeatureThumb2) != 0".

llvm-svn: 134678

be the first encoded as the first feature. It then uses the CPU name to look up
features / scheduling itineray even though clients know full well the CPU name
being used to query these properties.

The fix is to just have the clients explictly pass the CPU name!

character in std::string was causing failures for a few ObjC and Obj-C++ tests
when -flto was enabled.  Revision 133999 resolved this issue. Thanks Jay!

avoid getting embedded trailing null bytes in std::strings.

This was causing compile-time failures for some of the Objc and Obj-C++
benchmarks.  The specific errors were of the form: "ld: duplicate symbol …"

method.

This also make getExprForFDESymbol on ELF equal to the one on MachO, and it
can be made non-virtual.
