   having two tokens of look-ahead, or by having tricky code (which we

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.

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.

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.

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.

2006-06-21 04:57:09 +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.

2006-06-21 03:27:29 +00:00
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.

llvm-svn: 38552
2006-06-18 16:28:59 +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).
