Chris Lattner b352e3edb5 Change KeepComments/KeepMacroComments modes to be facets of the preprocessor 
state, not aspects of the language standard being parsed.

Chris Lattner b8d6d5a81d Formalize preprocessor callbacks together into a PPCallbacks structure, instead 
of having a loose collection of function pointers.  This also allows clients to
maintain state, and reduces the size of the Preprocessor.h interface.

the common case.

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).

llvm-svn: 38666
 2006-07-04 21:24:33 +00:00
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.
