2007-07-23implement a missing feature in the #include handler, whereChris Lattner
it did not handle <xyz> headers coming from macro expansions. This requires special treatment, as the include name is lexed as multiple tokens, which require reassembly before processing. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@40418 91177308-0d34-0410-b5e6-96231b3b80d8
2007-07-23refactor the interface to Preprocessor::GetIncludeFilenameSpelling,Chris Lattner
no functionality changes. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@40414 91177308-0d34-0410-b5e6-96231b3b80d8
2007-07-22fix a bug getting the spelling of an identifier tokenChris Lattner
that required cleaning. If the token required cleaning, don't include the cleaned tokens in the returned length. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@40410 91177308-0d34-0410-b5e6-96231b3b80d8
2007-07-20At one point there were going to be lexer and parser tokens.Chris Lattner
Since that point is now long gone, we should rename LexerToken to Token, as it is the only kind of token we have. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@40105 91177308-0d34-0410-b5e6-96231b3b80d8
2007-07-20simplify the lexer ctor to take a SLoc instead of a sloc and a redundant ↵Chris Lattner
buffer*. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@40104 91177308-0d34-0410-b5e6-96231b3b80d8
2007-07-20Reimplement SourceLocation. Instead of having a Chris Lattner
fileid/offset pair, it now contains a bit discriminating between mapped locations and file locations. This separates the tables for macros and files in SourceManager, and allows better separation of concepts in the rest of the compiler. This allows us to have *many* macro instantiations before running out of 'addressing space'. This is also more efficient, because testing whether something is a macro expansion is now a bit test instead of a table lookup (which also used to require having a srcmgr around, now it doesn't). This is fully functional, but there are several refinements and optimizations left. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@40103 91177308-0d34-0410-b5e6-96231b3b80d8
2007-07-19Fix a stringizing bug that Neil noticed. We should preprocess this:Chris Lattner
#define t(x) #x t(a c) to "a c", not "ac". git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@40060 91177308-0d34-0410-b5e6-96231b3b80d8
2007-07-19Correctly respect C99 5.1.1.2p4 when searching for the first '(' ofChris Lattner
a function-like macro invocation. Patch contributed by Neil Booth. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@40026 91177308-0d34-0410-b5e6-96231b3b80d8
2007-07-16Add a new Preprocessor::AdvanceToTokenCharacter method which, given a slocChris Lattner
specifying the start of a token and a logical (phase 3) character number, returns a sloc representing the input character corresponding to it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@39905 91177308-0d34-0410-b5e6-96231b3b80d8
2007-07-15Cache macro expander objects to avoid thrashing malloc in heavy expansion ↵Chris Lattner
situations. This doesn't significantly improve carbon.h, but it does speed up INPUTS/macro_pounder_obj.c by 48% git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@39864 91177308-0d34-0410-b5e6-96231b3b80d8
2007-07-14switch function-like macros from using a vector for their arguments to anChris Lattner
explicitly new'd array. The array never mutates once created, so a vector is overkill. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@39862 91177308-0d34-0410-b5e6-96231b3b80d8
2007-07-14expose an iterator interface to getReplacementTokens instead of the ↵Chris Lattner
datastructure itself. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@39860 91177308-0d34-0410-b5e6-96231b3b80d8
