Chris Lattner f2e3ac3b54 reimplement identifier hash table in terms of a probed table instead of a chained 
table.  This is about 25% faster for identifier lookup.  This also implements
resizing of the hash table.

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 
test/Preprocessor/macro_rescan_varargs.c

llvm-svn: 38783
 2006-07-29 06:30:25 +00:00

 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

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 
test/Lexer/badstring_in_if0.c

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. 
llvm-svn: 38747
 2006-07-20 04:47:30 +00:00
Chris Lattner 538d7f3c27 Simplify "raw lexing mode" even further. Now the preprocessor is only called 
into when a hard error is found.  This simplifies logic and eliminates the need
for the preprocessor to know about raw mode.

llvm-svn: 38746
 2006-07-20 04:31:52 +00:00
Chris Lattner 0f1f50517b Simplify identifier lookup in raw mode, implementing Preprocessor/macro_fn_lparen_scan2.c. 
llvm-svn: 38744
 2006-07-20 04:16:23 +00:00
Chris Lattner a7e2e74cef Avoid testing / ## * in the lexer. This will cause an unhelpful error message 
to be emitted from the lexer.  This fixes macro_paste_c_block_comment.c

llvm-svn: 38737
 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.

llvm-svn: 38736
 2006-07-19 06:31:49 +00:00
Chris Lattner e8dcfef324 Fix test/Preprocessor/macro_paste_spacing.c 
llvm-svn: 38734
 2006-07-19 05:45:55 +00:00
Chris Lattner 01ecf835c2 Implement basic token pasting (## operator). This implements 
test/Preprocessor/macro_paste_simple.c and macro_paste_bad.c.  There are
several known bugs still.

llvm-svn: 38733

llvm-svn: 38730
 2006-07-19 04:36:03 +00:00
Chris Lattner 7e2e669080 Handle really simple expansion of ## formals. Do not handle the empty case 
yet though.

llvm-svn: 38729
 2006-07-19 03:51:26 +00:00
Chris Lattner 2183a6e8f4 Make end-of-file handling much less recursive. This reduces the worst case 
stack depth sampled by shark from ~34 to ~17 frames when preprocessing <iostream>.

llvm-svn: 38726
 2006-07-18 06:36:12 +00:00
Chris Lattner 7667d0d942 Implement support for lexing from a pre-constructed token stream. 
Use this support to implement function-like macro argument preexpansion.

This implements test/Preprocessor/macro_fn_preexpand.c

llvm-svn: 38724
 2006-07-16 18:16:58 +00:00
Chris Lattner 203b4568e2 Implement basic argument substitution. This implements

llvm-svn: 38717
 2006-07-15 07:51:24 +00:00
Chris Lattner ee8760b21b Rename macroformalargs -> MacroArgs, as it represents the actual arguments, 
not the formal arguments, to a macro.

llvm-svn: 38716
 2006-07-15 07:42:55 +00:00
Chris Lattner c653246bfb Eliminate the IdentifierInfo::IsMacroArg flag. 
llvm-svn: 38715

Chris Lattner b935d8cd90 Set up infrastructure for function-like macro expansion with preexpansion 
stringizing, etc.

llvm-svn: 38707
 2006-07-14 06:54:44 +00:00
Chris Lattner b94ec7b668 Add an API so that external clients can create strings in the scratch buffer. 
llvm-svn: 38706
 2006-07-14 06:54:10 +00:00
Chris Lattner 041bef8b32 The lexer should not warn about stray characters, it should just return 
tok::unknown tokens.  This fixes test/Lexer/unknown-char.c

llvm-svn: 38703
 2006-07-11 05:52:53 +00:00
Chris Lattner 678c880a69 Move Preprocessor::isNextPPTokenLParen to Lexer::isNextPPTokenLParen, where 
it more rightly belongs.

llvm-svn: 38702
 2006-07-11 05:46:12 +00:00
Chris Lattner 3ebcf4e2cd Change Preprocessor::SkippingContents into Lexer::LexingRawMode. Raw mode 
is an intra-lexer property, not a inter-lexer property, so it makes sense
for it to be define here.  It also makes no sense for macros, and allows us
to define it more carefully in the header.

While I'm at it, improve comments and structuring in Lexer.h

llvm-svn: 38701
 2006-07-11 05:39:23 +00:00
Chris Lattner 69f88b883d Fix a regression on Preprocessor/hash_space.c 
llvm-svn: 38700
 2006-07-11 05:07:29 +00:00
Chris Lattner d8aee0e81b Implement "lparen scanning" for lexer buffers, by making "skipping lexing" 
completely reversible.  This implements tests 3/4 of
test/Preprocessor/macro_fn_lparen_scan.c

llvm-svn: 38699

llvm-svn: 38697
 2006-07-11 04:09:02 +00:00
Chris Lattner afe603fa7d Implement scanning-for-( more correctly. This implements 
test/Preprocessor/macro_fn_lparen_scan.c, but is not yet complete.

Add some FIXME's about missing diagnostics on empty macro args.  Improve some
comments.

llvm-svn: 38694
 2006-07-11 04:02:46 +00:00
Chris Lattner eb54b5973e Add simple optimization: check for (and skip) spaces and tabs immediately 
before lexing a token.  This speeds the common case where tokens are
separated by small amount of whitespace.  This makes a slight but
reproducible positive effect lexing a preprocessed carbon.h.

llvm-svn: 38691
 2006-07-10 06:34:27 +00:00
Chris Lattner 03f83485bd Only do an expensive walk over the entire identifier table if the diagnostic 
that needs it is enabled.

llvm-svn: 38690
 2006-07-10 06:16:26 +00:00
Chris Lattner d0a96ba38a Add a simple but useful optimization for identifier lookup. Each time we 
query the hash table, when we look up an identifier that isn't at the head
of it's bucket's list, move it there.  This reduces the number of list
traversals in the common case where identifiers are used in bursts.
