Chris Lattner 54d032bb76 CStringMap -> StringMap. 
llvm-svn: 39334
 2007-02-08 19:24:25 +00:00
Chris Lattner 34d1f5a8de adjust to CStringMap interface change. 
llvm-svn: 39333
 2007-02-08 19:08:49 +00:00
Chris Lattner 9561a0b3e7 Add support for target-independent builtin functions (like __builtin_abs), 
whose decl objects are lazily created the first time they are referenced.
Builtin functions are described by the clang/AST/Builtins.def file, which
makes it easy to add new ones.

This is missing two important pieces:
1. Support for the rest of the gcc builtins.
2. Support for target-specific builtins (e.g. __builtin_ia32_emms).

Just adding this builtins reduces the number of implicit function definitions
by 6, reducing the # diagnostics from 550 to 544 when parsing carbon.h.

I need to add all the i386-specific ones to eliminate several hundred more.
ugh.

llvm-svn: 39327
 2007-01-28 08:20:04 +00:00
Chris Lattner 3e7592ea78 Add support for -fno-operator-names, patch by Bill. 
llvm-svn: 39245
 2006-12-04 07:48:37 +00:00
Chris Lattner 652c16924e Produce a nice error message for '#define and' in C++. Patch by Bill! 
llvm-svn: 39218
 2006-11-21 23:47:30 +00:00
Chris Lattner 2bb8a95389 eliminate string compares when checking for the 'defined' token.

Chris Lattner 5b9f4891d7 Add support for C++ operator keywords. Patch by Bill Wendling. 
llvm-svn: 39214
 2006-11-21 17:23:33 +00:00
Chris Lattner b352e3edb5 Change KeepComments/KeepMacroComments modes to be facets of the preprocessor 
state, not aspects of the language standard being parsed.

llvm-svn: 39209
 2006-11-21 06:17:10 +00:00
Chris Lattner ad7cdd37b3 simplify the Preprocessor ctor. 
llvm-svn: 39208
 2006-11-21 06:08:20 +00:00
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.

llvm-svn: 39203
 2006-11-21 04:09:30 +00:00
Chris Lattner c95c8f2356 Fix a bug 
llvm-svn: 39128

 2006-11-03 06:42:29 +00:00
Chris Lattner 9f6604fa60 Add altivec version of block comment skipping code. 
llvm-svn: 39093
 2006-10-30 20:01:22 +00:00
Chris Lattner c07ba1fe2f Refactor the paths used for checking and getting the spelling of #include 
filenames (and also '#pragma GCC dependency' of course).  Now, assuming
no cleaning is needed, we can go all the way from lexing the filename to
doing filename lookups with no mallocs.  This speeds up user PP time from
0.077 to 0.075s for Cocoa.h (2.6%).

llvm-svn: 39092
 2006-10-30 05:58:32 +00:00
Chris Lattner b8b94f1e9b Make Preprocessor::LookupFile take a character range instead of a string. 
This avoids some copying in its clients.

llvm-svn: 39091
 2006-10-30 05:38:06 +00:00
Chris Lattner 7cdbad945d Push strings out of the HeaderSearch interface, it now deals solely with 
character ranges.

llvm-svn: 39090
 2006-10-30 05:33:15 +00:00
Chris Lattner ee7bf89cd6 Change framework cache map from map to CStringMap. This speeds up PP user 
time on Cocoa.h from 0.078 to 0.077s.

llvm-svn: 39089
 2006-10-30 05:19:23 +00:00
Chris Lattner b201d9b13d Eliminate string use in DoFrameworkLookup. This speeds up pp of Cocoa.h 
marginally from 0.079 to 0.078s.

llvm-svn: 39088
 2006-10-30 05:09:49 +00:00
Chris Lattner cf8ddac4bc Use SmallString instead of string in HeaderSearch::LookupFile. This avoids 
malloc traffic, speeding up user time preprocessing Carbon.h 5% (0.083s to
0.079s).

llvm-svn: 39087
 2006-10-30 04:42:33 +00:00
Chris Lattner 43fd42e4d9 Wean LookupSubframeworkHeader off std::strings, use the new SmallString 
class instead.  SmallString allows to code to avoid hitting malloc in
the normal case (or will, when some other stuff is converted over).

llvm-svn: 39084

llvm-svn: 39059
 2006-10-27 04:12:35 +00:00
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: 39058
 2006-10-27 03:59:10 +00:00
Chris Lattner 341fd06d3c Use the full hash as a filter to reduce # strcmps

 2006-10-18 06:07:05 +00:00
Chris Lattner 59a9ebdb17 refactor header searching stuff out of the main Preprocessor object into

llvm-svn: 38800
 2006-07-30 08:40:43 +00:00

llvm-svn: 38762
 2006-07-28 05:10:36 +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: 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: 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

 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 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

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

Chris Lattner d0a96ba38a Add a simple but useful optimization for identifier lookup. Each time we
