* more SourceLocation lexicon change: instead of referring to theChris Lattner2009-01-161-4/+4
| | | | | | "logical" location, refer to the "instantiation" location. llvm-svn: 62316
* Change some terminology in SourceLocation: instead of referring to Chris Lattner2009-01-161-6/+6
| | | | | | | the "physical" location of tokens, refer to the "spelling" location. This is more concrete and useful, tokens aren't really physical objects! llvm-svn: 62309
* rdar://6060752 - don't warn about trigraphs in bcpl-style commentsChris Lattner2008-12-121-1/+6

* Objective-C keywords are not always identifiers. Some are also C++ keywordsDouglas Gregor2008-12-011-2/+3

* Comment fix.Daniel Dunbar2008-11-251-1/+1

* Fix a weird inconsistency with hex floats. Previously the lexer Chris Lattner2008-11-221-2/+2
| | | | | | | | | 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. llvm-svn: 59865
* actually, this version isn't really needed.Chris Lattner2008-11-221-6/+2

* remove a sneaky version of Diag hiding in PreprocessorLexer.Chris Lattner2008-11-221-3/+6
| | | | llvm-svn: 59858
* Change the Lexer::Diag method to not magically silence warnings,Chris Lattner2008-11-221-27/+46
| | | | | | | force the caller to check instead. This eliminates the need (and the risk!) of weird null DiagnosticBuilder's floating around. llvm-svn: 59856
* Split the DiagnosticInfo class into two disjoint classes:Chris Lattner2008-11-221-2/+2
| | | | | | | | | | 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. llvm-svn: 59849
* - Move static function IsNonPragmaNonMacroLexer into Preprocessor.h.Ted Kremenek2008-11-191-2/+5
| | | | | | | | | | | | | - 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. llvm-svn: 59666

* Move some diagnostic handling to PreprocessorLexer.Ted Kremenek2008-11-121-10/+5
| | | | llvm-svn: 59191
* Remove Lexer::LexIncludeFilename.Ted Kremenek2008-11-121-21/+0
| | | | llvm-svn: 59186
* Change FormTokenWithChars to take the token kind to form, since all clientsChris Lattner2008-10-121-126/+107
| | | | | | | were setting a kind and then forming it. This is just a minor API cleanup, no functionality change. llvm-svn: 57404
* When in keep whitespace mode, make sure to return block comments that areChris Lattner2008-10-121-2/+22
| | | | | | unterminated. llvm-svn: 57403
* Change SkipBlockComment and SkipBCPLComment to return true when inChris Lattner2008-10-121-18/+22
| | | | | | keep comment mode, instead of returning false. This matches SkipWhitespace. llvm-svn: 57402
* Add a new mode to the lexer which enables it to return all characters,Chris Lattner2008-10-121-15/+49
| | | | | | | | | | | | | | | | | | | | | | | | even whitespace, as tokens from the file. This is enabled with L->SetKeepWhitespaceMode(true) on a raw lexer. In this mode, you too can use clang as a really complex version of 'cat' with code like this: Lexer RawLex(SourceLocation::getFileLoc(SM.getMainFileID(), 0), PP.getLangOptions(), File.first, File.second); RawLex.SetKeepWhitespaceMode(true); Token RawTok; RawLex.LexFromRawLexer(RawTok); while (RawTok.isNot(tok::eof)) { std::cout << PP.getSpelling(RawTok); RawLex.LexFromRawLexer(RawTok); } This will emit exactly the input file, with no canonicalization or other translation. Realistic clients actually do something with the tokens of course :) llvm-svn: 57401
* Fix a couple more places that poke KeepCommentMode unnecesarily. Chris Lattner2008-10-121-3/+4
| | | | llvm-svn: 57398
* add a new inKeepCommentMode() accessor to abstract the KeepCommentModeChris Lattner2008-10-121-4/+4

* Simplify raw mode lexing by treating an unterminate /**/ comment theChris Lattner2008-10-121-3/+4
| | | | | | | | same we we do an unterminated string or character literal. This makes it so we can guarantee that the lexer never calls into the preprocessor (which would be suicide for a raw lexer). llvm-svn: 57395
* add a comment.Chris Lattner2008-10-121-0/+2
| | | | llvm-svn: 57394
* Change how raw lexers are handled: instead of creating them and thenChris Lattner2008-10-121-5/+6
| | | | | | | | | | | using LexRawToken, create one and use LexFromRawLexer. This avoids twiddling the RawLexer flag around and simplifies some code (even speeding raw lexing up a tiny bit). This change also improves the token paster to use a Lexer on the stack instead of new/deleting it. llvm-svn: 57393

* Change Parser & Sema to use interned "super" for comparions.Daniel Dunbar2008-08-141-6/+0
| | | | | | | | | | | | | | - Added as private members for each because it is not clear where to put the common definition. Perhaps the IdentifierInfos all of these "pseudo-keywords" should be collected into one place (this would KnownFunctionIDs and Objective-C property IDs, for example). Remove Token::isNamedIdentifier. - There isn't a good reason to use strcmp when we have interned strings, and there isn't a good reason to encourage clients to do so. llvm-svn: 54794

* Make a major restructuring of the clang tree: introduce a top-levelChris Lattner2008-03-151-0/+1661
lib dir and move all the libraries into it. This follows the main llvm tree, and allows the libraries to be built in parallel. The top level now enforces that all the libs are built before Driver, but we don't care what order the libs are built in. This speeds up parallel builds, particularly incremental ones. llvm-svn: 48402
