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 2b11c7de4a Add MCAsmLexer interface. 
- This provides the AsmLexer interface to the target specific assembly parsers.

Chris Lattner 693fbb8fee implement .include in the lexer/parser instead of passing it into the streamer.

Daniel Dunbar c9dc78ae40 Normalize SourceMgr messages. 
- Don't print "Parsing" in front of every message.

 - Take additional "type" argument which is prepended to the message (with ": ")
   if given.

 - Update clients to print errors (warnings) as:
<filename>:<line number>: error(warning): ...

std::strings.

Chris Lattner f97d8bbe73 implement a trivial binary expression parser, we can now parse all of 176.gcc.llc.s 
llvm-svn: 73950
 2009-06-23 05:57:07 +00:00
Chris Lattner 7fdbce7a60 Implement full support for parsing primary expressions. We can now parse 
all of health and voronoi (ignoring directives).  We only get 409 lines into
176.gcc though because we don't have binary operators yet:

Parsing 176.gcc.llc.s:409: unexpected token in operand list
	movsbl	_arityvec+1(,%edi,8), %eax
	      	         ^

Chris Lattner d0765617d2 implement enough of a lexer to get through Olden/health/Output/health.llc.s 
without errors.
