Chris Lattner 6c20391d38 split MachO section handling stuff out to its out .h/.cpp file. 
llvm-svn: 78576
 2009-08-10 18:15:01 +00:00
Chris Lattner 97189e5d04 add a fixme 
llvm-svn: 78575
 2009-08-10 18:05:55 +00:00
Chris Lattner cb307a27bf Make the big switch: Change MCSectionMachO to represent a section *semantically* 
instead of syntactically as a string.  This means that it keeps track of the 
segment, section, flags, etc directly and asmprints them in the right format.
This also includes parsing and validation support for llvm-mc and 
"attribute(section)", so we should now start getting errors about invalid 
section attributes from the compiler instead of the assembler on darwin.

Still todo: 
1) Uniquing of darwin mcsections
2) Move all the Darwin stuff out to MCSectionMachO.[cpp|h]
3) there are a few FIXMEs, for example what is the syntax to get the
   S_GB_ZEROFILL segment type?

Chris Lattner 591105c540 sink the 'name' and 'isdirective' state out of MCSection into its derived classes. 
This totally optimizes PIC16 sections by not having an 'isdirective' bit anymore!! ;-)

 2009-08-08 23:39:42 +00:00
Chris Lattner 089b7de20d switch this to create coff sections for now, it doesn't really matter for 
llvm-mc's purpose yet and we'll want to switch to creating semantic sections
at some point.

Benjamin Kramer 7641cf8e4d Always initialize AsmConds. 
llvm-svn: 78463
 2009-08-08 11:26:50 +00:00
Kevin Enderby d9f952948e Added Mac OS X assembler style conditional assembly. I may come back and see if 
I can clean this up a bit more and do way with the TheCondState and just use
the top element on the TheCondStack if not empty.  Also may tweak the code
around ParseConditionalAssemblyDirectives() to simplify the AsmParser code.

Daniel Dunbar c54ecb384d llvm-mc: More quoted identifier support. 
llvm-svn: 77761
 2009-08-01 00:48:30 +00:00
Daniel Dunbar 9ee33ca28e llvm-mc: Support quoted identifiers. 
- Uses MCAsmToken::getIdentifier which returns the (sub)string representing the
   meaningfull contents a string or identifier token.

 - Directives aren't done yet.

Daniel Dunbar 52d03b252e llvm-mc: Move AsmLexer::getCurStrVal to StringRef based API. 
- My DFS traversal of LLVM is, at least for now, nearly complete! :)

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.

 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

- This provides the AsmParser interface to the target specific assembly
   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.
