llvm-svn: 38805
 2006-08-04 04:39:53 +00:00
Chris Lattner 70f32b7d68 Add initial very-incomplete support for parsing declarations. We just manage 
to be able to parse "int x;" now.

llvm-svn: 38803
 2006-07-31 05:09:04 +00:00
Chris Lattner 0bb5f835e4 initial support for parsing, right now just ;'s at the top level, but this 
adds most simple scaffolding.

llvm-svn: 38802
 2006-07-31 01:59:18 +00:00
Chris Lattner 34dfaee634 Misc cleanups 
llvm-svn: 38801
 2006-07-31 01:57:54 +00:00
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

llvm-svn: 38783
 2006-07-29 06:30:25 +00:00
Chris Lattner 775d832110 Implement the GNU comma swallowing extension. This implements 
test/Preprocessor/macro_fn_comma_swallow.c

llvm-svn: 38780
 2006-07-29 04:39:41 +00:00
Chris Lattner 21c8b8f71e Implement support for __VA_ARGS__, allowing test/Preprocessor/macro_fn_varargs_iso.c 
to pass.

llvm-svn: 38776
 2006-07-29 04:04:22 +00:00
Chris Lattner 6d9f8ed3b6 No need for explicit underscore anymore. 
llvm-svn: 38773
 2006-07-29 03:52:06 +00:00
Chris Lattner f9771166ed add method to unpoison something for __VA_ARGS__. 
llvm-svn: 38772
 2006-07-29 03:47:18 +00:00

llvm-svn: 38771
 2006-07-29 03:47:08 +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 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 7fa8c889e2 Add a single-entry cache for macro instantation locations. This significantly 
reduces the number of FileID's made and tracked.

llvm-svn: 38752
 2006-07-20 06:48:52 +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 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 22549fe6a5 With recent simplifications, this check can be removed from a fastpath. 
llvm-svn: 38745

llvm-svn: 38740
 2006-07-19 06:41:46 +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 05:42:48 +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 e1954ac1a3 Fix comment 
llvm-svn: 38721
 2006-07-15 23:40:13 +00:00

test/Preprocessor/macro_fn_disable_expand.c

llvm-svn: 38720
 2006-07-15 21:07:40 +00:00
Chris Lattner 2ada5d3890 More changes from formals -> actuals. 
llvm-svn: 38717
 2006-07-15 07:51:24 +00:00

not the formal arguments, to a macro.

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

Chris Lattner c783d1dff9 Implement the microsoft charize extension #@ 
llvm-svn: 38712

 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

 2006-07-11 04:03:32 +00:00

llvm-svn: 38652
 2006-07-04 18:11:39 +00:00
Chris Lattner c79f6fb108 Rename IdentifierTokenInfo -> IdentifierInfo. 
llvm-svn: 38650
 2006-07-04 17:53:21 +00:00
Chris Lattner a8654ca2cf Eliminate MultipleIncludeOpt::ReadDirective and all calls to it. Any directives 
that are lexed are made up of tokens, so the calls are just ugly and redundant.

Hook up the MIOpt for the #if case.  PPCExpressions doesn't currently implement
the hook though, so we still don't handle #if !defined(X) with the MIOpt.

Chris Lattner 0c885f5581 Improve #line emission in -E mode to include file entry/exits. This is 
still pretty hacky because it doesn't compute the 3/4 markers correctly.

Chris Lattner 30709b038d Implement a new type of FileID: FileIDInfo::MacroExpansion. For tokens that 
came from a macro expansion, this allows us to keep track of both where the
character data came from and where the logical position of the token is (at
the expansion site).  This implements Preprocessor/indent_macro.c, and
reduces the number of cpp iostream -E diffs vs GCC from 2589 to 2297.

Chris Lattner d01e291332 Make a fundamental change to the way we represent the location of LexerToken's. 
Now, instead of keeping a pointer to the start of the token in memory, we keep the
start of the token as a SourceLocation node.  This means that each LexerToken knows
the full include stack it was created with, and means that the LexerToken isn't
reliant on a "CurLexer" member to be around (lexer tokens would previously go out of
scope when their lexers were deallocated).

This simplifies several things, and forces good cleanup elsewhere.  Now the
Preprocessor is the one that knows how to dump tokens/macros and is the one that
knows how to get the spelling of a token (it has all the context).
