 2006-07-05 00:08:00 +00:00
Chris Lattner 27746e476a Fix Preprocessor/macro_space.c, which failed because the ! token had 
identifier info incorrectly set.

Chris Lattner f46be6cb02 Switch to using unix "write" when available, instead of stdio. This speeds up 
-E -P mode by 10% (i.e. takes away almost all i/o time).

Chris Lattner 3338ba87d5 Make -P mode faster and closer to GCC output by not emitting newlines at all. 
This allows the SourceManager to not compute line number information for each buffer.

Chris Lattner d5da3ea58d This matters for -E.

 2006-07-04 19:29:50 +00:00
Chris Lattner deb3701c23 Switch from using iostreams to using stdio for -E mode output. This speeds 
up clang -E iostream by 30%.

optimization.

PPExpressions.cpp instead of methods.

llvm-svn: 38651

Chris Lattner c79f6fb108 Rename IdentifierTokenInfo -> IdentifierInfo. 
llvm-svn: 38650
 2006-07-04 17:53:21 +00:00
Chris Lattner a8654ca2cf Eliminate MultipleIncludeOpt::ReadDirective and all calls to it. Any directives 
that are lexed are made up of tokens, so the calls are just ugly and redundant.

Hook up the MIOpt for the #if case.  PPCExpressions doesn't currently implement
the hook though, so we still don't handle #if !defined(X) with the MIOpt.
