2007-08-261.0 is double, 1.0F is a float.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@41412 91177308-0d34-0410-b5e6-96231b3b80d8
2007-08-261) refactor some code.Chris Lattner
2) Add support for lexing imaginary constants (a GCC extension): t.c:5:10: warning: imaginary constants are an extension A = 1.0iF; ^ 3) Make the 'invalid suffix' diagnostic pointer more accurate: t.c:6:10: error: invalid suffix 'qF' on floating constant A = 1.0qF; ^ instead of: t.c:6:10: error: invalid suffix 'qF' on floating constant A = 1.0qF; ^ git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@41411 91177308-0d34-0410-b5e6-96231b3b80d8
2007-08-23Add helper functions Token::isObjCAtKeyword() and Token::getObjCKeywordID().Steve Naroff
Convert all clients to the new cleaner, more robust API. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@41330 91177308-0d34-0410-b5e6-96231b3b80d8
2007-07-24Use a smallstring instead of an std::string in FileChanged to avoid some ↵Chris Lattner
malloc traffic. This speeds up -E on xalancbmk by 2.4% git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@40461 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
2007-07-22Change hte lexer to start a start pointer to the underlying Chris Lattner
memorybuffer instead of a pointer to the memorybuffer itself. This reduces coupling and eliminates a pointer dereference on a hot path. This speeds up -Eonly on 483.xalancbmk by 2.1% git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@40394 91177308-0d34-0410-b5e6-96231b3b80d8
2007-07-22Implement a simple cache in headersearch. This speeds upChris Lattner
preprocessing 483.xalancbmk by about 10%, reducing the number of file lookup queries from 2139411 to 199466 (over 10x) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@40390 91177308-0d34-0410-b5e6-96231b3b80d8
2007-07-22Fix a really subtle bug in the macro expander caching code, whereChris Lattner
redefinition of a macro could cause invalid memory to be deleted. Found preprocessing 253.perlbmk. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@40380 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
2007-07-16Add 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
2007-07-16factor a common predicate into a static method.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@39903 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
2007-07-14switch from using a vector to a smallvector for macro replacement tokensChris Lattner
This speeds up parsing carbon.h by 3.3% by avoiding some malloc traffic for small macros. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@39861 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
