Chris Lattner 59a9ebdb17 refactor header searching stuff out of the main Preprocessor object into 
it's own HeaderSearch object.  This makes Preprocessor simpler and easier
to understand.

Chris Lattner 2dacc3ff2e Changes through out the parser and actions/ast interface to return top-level 
declarations through the asm streamer.  For a testcase like:

int G;
int H, I, *J;
int func() {}

'clang -parse-print-ast' prints:

Read top-level decl: G
Read top-level decl: H
Read top-level decl: I
Read top-level decl: J
Read top-level decl: func

Chris Lattner 3338ba87d5 Make -P mode faster and closer to GCC output by not emitting newlines at all. 
This allows the SourceManager to not compute line number information for each buffer.

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
in -E mode.

llvm-svn: 38562
 2006-06-22 05:52:16 +00:00
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.

llvm-svn: 38561
 2006-06-21 06:50:18 +00:00
Chris Lattner d12ad77e40 Add really early support for emitting # line directives, and emitting the 
right number of newlines between tokens when needed.  This reduces the
delta of the gcc -E output from 12198 differences to 6764.  It still needs
to emit filenames on #line directives, track filename switches, and track
entry/exit of include files.

Chris Lattner 50b497e072 Rename LexerToken::getSourceLocation -> getLocation 
llvm-svn: 38553
 2006-06-18 16:32:35 +00:00
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).

 2006-06-18 16:22:51 +00:00
Chris Lattner 7e0dd2b11f Fix a fixme by passing language options into LexerToken::dump, instead of 
relying on TheLexer.
