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
2008-12-02Preprocessor:Ted Kremenek
- Added method "setPTHManager" that will be called by the driver to install a PTHManager for the Preprocessor. - Fixed some comments. - Added EnterSourceFileWithPTH to mirror EnterSourceFileWithLexer. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@60437 91177308-0d34-0410-b5e6-96231b3b80d8
2008-12-02Added PTHManager, a utility class that will be used by Preprocessor to ↵Ted Kremenek
lazily create PTHLexer objects for pre-tokenized files. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@60436 91177308-0d34-0410-b5e6-96231b3b80d8

__ASSEMBLER__ properly. Patch from Roman Divacky (with minor formatting changes). Thanks! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@60362 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

2008-11-23make the 'to match this' diagnostic a note.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59921 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-23Convert IdentifierInfo's to be printed the same as DeclarationNames Chris Lattner
with implicit quotes around them. This has a bunch of follow-on effects and requires tweaking to a whole lot of code. This causes a regression in two tests (xfailed) by causing it to emit things like: Line 10: duplicate interface declaration for category 'MyClass1' ('Category1') instead of: Line 10: duplicate interface declaration for category 'MyClass1(Category1)' I will fix this in a follow-up commit. As part of this, I had to start switching stuff to use ->getDeclName() instead of Decl::getName() for consistency. This is good, but I was planning to do this as an independent patch. There will be several follow-on patches to clean up some of the mess, but this patch is already too big. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59917 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-22Fix a weird inconsistency with hex floats. Previously the lexer Chris Lattner
would not eat the "-1" in "0x0p-1", but LiteralSupport would accept it when extensions are on. This caused strangeness and failures when hexfloats were properly treated as an extension (not error) in LiteralSupport. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59865 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-22remove the NumericLiteralParser::Diag helper method, inlining it intoChris Lattner
its call sites. This makes it more explicit when the hasError flag is getting set and removes a confusing difference in behavior between PP.Diag and Diag in this code. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59863 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-22Move the Preprocessor::Diag methods inline. This has the interestingChris Lattner
(and carefully calculated) effect of allowing the compiler to reason about the aliasing properties of DiagnosticBuilder object better, allowing the whole thing to be promoted to registers instead of resulting in a ton of stack traffic. While I'm not very concerned about the performance of the Diag() method invocations, I *am* more concerned about their code size and impact on the non-diagnostic code. This patch shrinks the clang executable (in release-asserts mode with gcc-4.2) from 14523980 to 14519816 bytes. This isn't much, but it shrinks the lexer from 38192 to 37776, PPDirectives.o from 31116 to 28868 bytes, etc. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59862 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-22inline a method into its only two call sites.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59860 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-22actually, this version isn't really needed.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59859 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
2008-11-22Split the DiagnosticInfo class into two disjoint classes:Chris Lattner
one for building up the diagnostic that is in flight (DiagnosticBuilder) and one for pulling structured information out of the diagnostic when formatting and presenting it. There is no functionality change with this patch. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59849 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

2008-11-21When creating the raw tokens for PTHLexer, make sure the token representing ↵Ted Kremenek
the file to include is checked for being an identifier. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59842 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-21When creating raw tokens for the PTHLexer specially handle angled strings ↵Ted Kremenek
for #include directives. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59840 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
2008-11-20Handle another case where we should use PTHLexer as an alternative to the ↵Ted Kremenek
normal Lexer. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59736 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
2008-11-20Rename IsNonPragmaNonMacroLexer to IsFileLexer.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59731 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
2008-11-20Add ugly "test harness" for PTHLexer that is not enabled by default. TheTed Kremenek
(temporary hack) to test the PTHLexer is that whenever we would create a Lexer object we instead raw lex a memory buffer first and then use the PTHLexer. This logic exists only to driver the PTHLexer and will be removed/changed in the future. Note that the regular path using normal Lexer objects is what is used by default. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59723 91177308-0d34-0410-b5e6-96231b3b80d8

2008-11-20Preprocessor::getCurrentFileLexer() now returns a PreprocessorLexer* instead ofTed Kremenek
a Lexer*. This means it will either return the current (normal) file Lexer or a PTHLexer. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59694 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-20Just use the SourceLocation of SysHeaderTok when doing a callback to emit #lineTed Kremenek
information. A diff of the -E output for Cocoa.h shows that there is no change in output. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59693 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-20Assign the result of getCurrentFileLexer() to a PreprocessorLexer* instead ↵Ted Kremenek
of Lexer* (narrower interface). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59691 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
2008-11-19Use PreprocessorLexer::getFileID() instead of Lexer::getFileLoc(). This is ↵Ted Kremenek
an intermediate step to having getCurrentLexer() return a PreprocessorLexer* instead of a Lexer*. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59672 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-19Move more cases of using 'CurLexer' to 'CurPPLexer'.Ted Kremenek
Use PTHLexer::isNextPPTokenLParen() when using the PTHLexer. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59671 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
