Chris Lattner c6ad8131dd implement AST representation for function types with and without a prototype. 
This lets us pretty print stuff like this:

void foo() {
  int X;
  X = sizeof(void (*(*)())());
  X = sizeof(int(*)(int, float, ...));
  X = sizeof(void (*(int arga, void (*argb)(double Y)))(void* Z));

as:

  X = sizeof(void (*(*)())())
  X = sizeof(int (*)(int, float, ...))
  X = sizeof(void (*(int, void (*)(double)))(void *))

Ah the wonders of 'modern' C syntax!

Chris Lattner cbc426d4f7 Next step of retaining information about function prototypes: actually retain 
the info.  Also, call Actions.ParseParamDeclaratorType instead of
Actions.ParseDeclarator for parameter type lists: we don't want declaration
objects created when parsing a function declarator, we just want type info.

 2006-12-02 06:43:02 +00:00
Chris Lattner edc9e39d88 First step towards accurately retaining information about function 
parameters: build an array of ParamInfo structures and pass it to the
declarator for safe keeping (it owns the list).

Next step: actually populate the arg array with useful stuff.

Chris Lattner 4d8f873b5b record accurate sourceloc info for storage class specs, so we can report 
things like:

t.c:4:10: error: invalid storage class specifier in function declarator
int foo2(auto int Aaslfkasdflkj, register B);
         ^

instead of:

t.c:4:19: error: invalid storage class specifier in function declarator
int foo2(auto int Aaslfkasdflkj, register B);

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 457fc15bc5 Implement comment saving mode: the -C and -CC options. 
llvm-svn: 38783
 2006-07-29 06:30:25 +00:00
Chris Lattner 775d832110 Implement the GNU comma swallowing extension. This implements

llvm-svn: 38780
 2006-07-29 04:39:41 +00:00

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

 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

several known bugs still.

llvm-svn: 38733
 2006-07-19 05:42:48 +00:00

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

Chris Lattner a8654ca2cf Eliminate MultipleIncludeOpt::ReadDirective and all calls to it. Any directives

#pragma once, and it is not completely implemented.

Chris Lattner c899718274 Track which headers are system and non-C++-clean-system headers. Use this 
information to print the 3/4 flags correctly on #line directives emitted

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).
