llvm-svn: 77292
 2009-07-28 03:00:54 +00:00
Daniel Dunbar 5cf338ad60 llvm-mc: Stop uniqueing string tokens, nothing actually uses this. 
llvm-svn: 77287
 2009-07-28 00:58:50 +00:00
Daniel Dunbar eb6bb32bef llvm-mc: Implement .abort fully in the front end 
llvm-svn: 77272
 2009-07-27 23:20:52 +00:00
Daniel Dunbar 52d03b252e llvm-mc: Move AsmLexer::getCurStrVal to StringRef based API. 
- My DFS traversal of LLVM is, at least for now, nearly complete! :)

llvm-svn: 77258
 2009-07-27 21:49:56 +00:00
Daniel Dunbar ee01b242e8 Factor commonality in triple match routines into helper template for registering 
classes, and migrate existing targets over.

llvm-svn: 77126
 2009-07-26 05:03:33 +00:00
Daniel Dunbar 47d679151b Add TargetRegistry::lookupTarget. 
- This is a simplified mechanism which just looks up a target based on the
   target triple, with a few additional flags.

 - Remove getClosestStaticTargetForModule, the moral equivalent is now:
     lookupTarget(Mod->getTargetTriple, true, false, ...);

 - This no longer does the fuzzy matching with target data (based on endianness
   and pointer width) that getClosestStaticTargetForModule was doing, but this
   was deemed unnecessary.

llvm-svn: 77111
 2009-07-26 02:12:58 +00:00
Daniel Dunbar 5bf72e20eb Convert StringMap to using StringRef for its APIs. 
- Yay for '-'s and simplifications!

 - I kept StringMap::GetOrCreateValue for compatibility purposes, this can
   eventually go away. Likewise the StringMapEntry Create functions still follow
   the old style.

 - NIFC.

Kevin Enderby ee5513582d Removed the DumpSymbolsandMacros and LoadSymbolsandMacros MCStreamer API as 
the parsing of the .dump and .load should be done in the assembly parser and
not have any need for an MCStreamer API.  Changed the code for now so these
just produce an error saying these specific directives are not yet implemented
since they are likely no longer used and may never need to be implemented.

llvm-svn: 76462
 2009-07-20 20:25:37 +00:00
Daniel Dunbar 2b11c7de4a Add MCAsmLexer interface.

llvm-svn: 76460
 2009-07-20 20:01:54 +00:00
Daniel Dunbar 3c2a893ac7 Add MCAsmParser interface.

   parsers.

 2009-07-17 22:38:58 +00:00
Kevin Enderby dd27e5e10a Removed the SubsectionsViaSymbols MCStreamer API and replaced it with a generic 
EmitAssemblerFlag API which takes a value from the added AssemblerFlag
enumerated constants.

llvm-svn: 74687
 2009-07-02 02:26:39 +00:00
Daniel Dunbar 9bff6531fd llvm-mc/x86: Fix bug in disambiguation of displacement operand, introduced by me 
(I think).
 - We weren't properly parsing the leading parenthesized expression in something
   like 'push (4)(%eax)'.
 
 - Added ParseParenRelocatableExpression to support this. I suspect we should
   just use lookahead, though.

 - Test case to follow.
