Chris Lattner 59a9ebdb17 refactor header searching stuff out of the main Preprocessor object into

Chris Lattner 95a06b34f7 Simplify implementation of varargs macros by adding the __VA_ARGS__ token 
to the formal argument list of a C99 varargs macro.

llvm-svn: 38800
 2006-07-30 08:40:43 +00:00
Chris Lattner 273ddd5c57 The optimized case has to treat __VA_ARGS__ as an argument. This fixes

 2006-07-29 03:46:57 +00:00
Chris Lattner e7a5130dff If the varargs token is missing, add an empty argument to represent it. This 
fixes Preprocessor/macro_fn_varargs_named.c

llvm-svn: 38769
 2006-07-29 01:25:12 +00:00
Chris Lattner f3f1c709cf Use a continue to avoid indentation of a bunch of code 
llvm-svn: 38762
 2006-07-28 05:10:36 +00:00
Chris Lattner a9dc597fca Implement pasting of arguments that expand to no tokens. This handles the 
C99 "placemarker" concept.

llvm-svn: 38761
 2006-07-28 05:07:04 +00:00
Chris Lattner 6e4bf523e6 Implement C99 6.10.3.4p2, testcase here: Preprocessor/macro_disable3.c. 
llvm-svn: 38760
 2006-07-27 06:59:25 +00:00
Chris Lattner b57aa46e41 Switch ExpandFunctionArguments to use a smallvector instead of a vector, 
speeding up my macro expansion torture test from .75s to .5s (33%!)

llvm-svn: 38758
 2006-07-27 03:42:15 +00:00
Chris Lattner 7a4af3b73d Change Preprocessor::ReadFunctionLikeMacroArgs to use a SmallVector to lex 
argument tokens into instead of a real vector.  This avoids some malloc
traffic in common cases.  In an "abusive macro expansion" testcase, this
reduced -Eonly time by 25%.

llvm-svn: 38757
 2006-07-26 06:26:52 +00:00
Chris Lattner c1410dc1e6 Change MacroArgs to allocate space for the unexpanded tokens immediately after 
the MacroArgs object itself.  This is a bit more efficient and will be even more
so shortly.

llvm-svn: 38756
 2006-07-26 05:22:49 +00:00
Chris Lattner 6fc08bc77d Add a new getArgLength method and refactor some code to use it 
llvm-svn: 38755
 2006-07-26 04:55:32 +00:00
Chris Lattner 7021657a0f Implement a FIXME: don't copy token array into a token vector, instead, macroexpander should expand from an array directly. 
llvm-svn: 38754
 2006-07-26 03:50:40 +00:00
Chris Lattner 36b6e8134e speed up a brutal macro-expansion torture test by about 30% (1.5 -> 1.0s) 
by turning vectors of vectors into a single vector, reducing pressure on
malloc.  This can still be improved.

llvm-svn: 38753
 2006-07-21 06:38:30 +00:00
Chris Lattner a5f4c882e2 disable malformed string/character errors when in raw mode. This fixes

llvm-svn: 38751
 2006-07-20 06:08:47 +00:00
Chris Lattner 5a78a02ea2 If an invalid string or character is read, return the invalid part as a tok::unknown token. 
llvm-svn: 38749
 2006-07-20 06:02:19 +00:00
Chris Lattner 08ba4c015f fix obvious bug that caused Preprocessor/macro_paste_bad.c to fail. 
llvm-svn: 38748
 2006-07-20 04:52:59 +00:00
Chris Lattner 510ab61fd3 Add optimization for identifier##identifier -> identifier, the most common case of token pasting.
