Chris Lattner 96c3deb53d Simplify handling of the ternary operator even more. Now it just looks like 
any average right-associative operator to most of the code.

 2006-08-12 17:13:08 +00:00
Chris Lattner d35c34f44d Fix incorrect parsing of the ?: middle term, which is supposed to be 
parsed as 'expression'.  This implements test/Parser/statements.c

 2006-08-12 17:04:23 +00:00
Chris Lattner a0927cecb5 Improve diagnostics on cases like: 
return a ? `  a;

After the expression is diagnosed, skip to the ';', so that the lack of
semicolon is not also diagnosed.

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

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.

Chris Lattner 538d7f3c27 Simplify "raw lexing mode" even further. Now the preprocessor is only called

 2006-07-19 06:32:35 +00:00
Chris Lattner 30a2fa14ae Move LexingRawMode handling of file EOF out of the preprocessor into the 
lexer.  This makes more logical sense and also unbreaks the case when the
lexer hasn't been pushed onto the PP include stack.  This is the case when
pasting identifiers.  This patch implements macro_paste_bcpl_comment.c.

to define it more carefully in the header.

Chris Lattner eb54b5973e Add simple optimization: check for (and skip) spaces and tabs immediately
