2009-01-18Avoid malloc thrashing on the std::vector for ConditionalStack. BecauseChris Lattner
there is one of these per header, this almost always gets alloc/free'd for each #ifdef. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62451 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-17this massive patch introduces a simple new abstraction: it makesChris Lattner
"FileID" a concept that is now enforced by the compiler's type checker instead of yet-another-random-unsigned floating around. This is an important distinction from the "FileID" currently tracked by SourceLocation. *That* FileID may refer to the start of a file or to a chunk within it. The new FileID *only* refers to the file (and its #include stack and eventually #line data), it cannot refer to a chunk. FileID is a completely opaque datatype to all clients, only SourceManager is allowed to poke and prod it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62407 91177308-0d34-0410-b5e6-96231b3b80d8
2008-12-10PreprocessorLexer (and subclasses):Ted Kremenek
- Added virtual method 'getSourceLocation()' (no arguments) that gets the location of the next "observable" location (e.g., next character, next token). PPLexerChange.cpp: - Implemented FIXME by using PreprocessorLexer::getSourceLocation() to get the location in the file we are returning to after lexing a #included file. This appears to be slightly faster than having the branch (i.e., 'if(CurLexer)'). It's also not a really hot part of the Preprocessor. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@60860 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-26Add setter method PreprocessorLexer::setParsingPreprocessorDirective(). ↵Ted Kremenek
This will be used by the mechanism to generate cached tokens. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@60070 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-22remove a sneaky version of Diag hiding in PreprocessorLexer.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59858 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-22Change the Lexer::Diag method to not magically silence warnings,Chris Lattner
force the caller to check instead. This eliminates the need (and the risk!) of weird null DiagnosticBuilder's floating around. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59856 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-20- Default initialize ParsingPreprocessorDirective, ParsingFilename, andTed Kremenek
LexingRawMode in the ctor of PreprocessorLexer. - PTHLexer: Use "LastToken" instead of "NumToken" git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59690 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-19- Move static function IsNonPragmaNonMacroLexer into Preprocessor.h.Ted Kremenek
- Add variants of IsNonPragmaNonMacroLexer to accept an IncludeMacroStack entry (simplifies some uses). - Use IsNonPragmaNonMacroLexer in Preprocessor::LookupFile. - Add 'FileID' to PreprocessorLexer, and have Preprocessor query this fileid when looking up the FileEntry for a file Performance testing of -Eonly on Cocoa.h shows no performance regression because of this patch. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59666 91177308-0d34-0410-b5e6-96231b3b80d8

2008-11-12Move pieces of Lexer that the Preprocessor mutates to a new base class ↵Ted Kremenek
'PreprocessorLexer'. This will also be the base class of the new Preprocessed-Token-Header (PTH) lexer. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59168 91177308-0d34-0410-b5e6-96231b3b80d8
