2008-12-04Remove unneeded assertion.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@60559 91177308-0d34-0410-b5e6-96231b3b80d8
2008-12-04Use 'free' to release PerIDCache since it was allocated using calloc().Ted Kremenek

2008-12-03PTH:Ted Kremenek
Use an array instead of a DenseMap to cache persistent IDs -> IdentifierInfo*. This leads to a 4% speedup at -fsyntax-only using PTH. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@60452 91177308-0d34-0410-b5e6-96231b3b80d8
2008-12-03- Remove PTHManager.cpp. Move all of its functions to PTHLexer.cpp since ↵Ted Kremenek
some of the internal methods are used by PTHLexer (their implementations are intertwined.) This enables some important inlining opportunities at -O3. - Don't construct an std::vector<Token> prior to feeding PTH tokens to the Preprocessor. Stream them off the PTH file directly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@60447 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-27PTHLexer now owns the Token vector.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@60136 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-21In PTHLexer::DiscardToEndOfLine() use Lex() instead of AdvanceToken(). This ↵Ted Kremenek
handles transitions in the preprocessor state. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59845 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-21PTHLexer:Ted Kremenek
- Move out logic for handling the end-of-file to LexEndOfFile (to match the Lexer) class. The logic now mirrors the Lexer class more, which allows us to pass most of the Preprocessor test cases. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59768 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-20PTHLexer:Ted Kremenek
- Move PTHLexer::GetToken() to be inside PTHLexer.cpp. - When lexing in raw mode, null out identifiers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59744 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-20PTHLexer:Ted Kremenek
- Rename 'CurToken' and 'LastToken' to 'CurTokenIdx' and 'LastTokenIdx' respectively. - Add helper methods GetToken(), AdvanceToken(), AtLastToken() to abstract away details of the token stream. This also allows us to easily replace their implementation later. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59733 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-20Rewrote PTHLexer::Lex by digging through the sources of Lexer again. Now we ↵Ted Kremenek
can do basic macro expansion using the PTHLexer. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59724 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
2008-11-20Add (untested) implementation of PTHLexer::isNextPPTokenLParen() and ↵Ted Kremenek
PTHLexer::DiscardToEndOfLine(). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59687 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-19Add stub for PTHLexer::isNextPPTokenLParen().Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59670 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-19When using a PTHLexer, use DiscardToEndOfLine() instead of ReadToEndOfLine().Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59668 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
