Chris Lattner e8eef3207b add infrastructure for warning if redef'd macro bodies differ, but don't 
fully implement it.

Fix warning on #define __LINE__ to warn about redefinition, not #undef.

Chris Lattner ae41157ee5 Implement support for arbitrarily mapping non-error diagnostics to be either 
ignored, warned about, or error'd.  Use this to implement the -Wunused_macros
command line option.

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.

optimization.

 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.
