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
2008-11-27PTHLexer now owns the Token vector.Ted Kremenek

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
2008-11-20Rename IsNonPragmaNonMacroLexer to IsFileLexer.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59731 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-20Add 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
2008-11-20Make FIXME a hard assertion.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59695 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
2008-11-19Move 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

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59579 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. 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@59574 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-18- Add Lexer::isPragma() accessor for clients of Lexer that aren't friends.Ted Kremenek
- Add static method to test if the current lexer is a non-macro/non-pragma lexer. - Refactor some code in PPLexerChange to use this static method. - No performance change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59486 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-18- Add 'CurPPLexer' to Preprocessor to keep track of the currentTed Kremenek
PreprocessorLexer, which will either be a 'Lexer' or 'PTHLexer'. - Added stub field 'CurPTHLexer' to keep track of the current PTHLexer. - Modified IncludeStackInfo to track both the current PTHLexer and current PreprocessorLexer. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59472 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-13Using llvm::OwningPtr<> for CurLexer and CurTokenLexer. This makes both the ↵Ted Kremenek
ownership semantics of these objects explicit within the Preprocessor and also tightens up the code (explicit deletes not needed). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59249 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-13Use PushIncludeMacroStack/PopMacroStack instead of manually pushing/popping ↵Ted Kremenek
from IncludeMacroStack. This is both cleaner and makes the include stack transparently extensible. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59248 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@58224 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-12Change FormTokenWithChars to take the token kind to form, since all clientsChris Lattner
were setting a kind and then forming it. This is just a minor API cleanup, no functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@57404 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-26clean up a bunch of fixme's I added, by moving Chris Lattner
DirectoryLookup::DirType into SourceManager.h git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@56692 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-26Fix the rest of rdar://6243860 hopefully. This requires changing FileIDInfoChris Lattner
to whether the fileid is a 'extern c system header' in addition to whether it is a system header, most of this is spreading plumbing around. Once we have that, PPLexerChange bases its "file enter/exit" notifications to PPCallbacks to base the system header state on FileIDInfo instead of HeaderSearch. Finally, in Preprocessor::HandleIncludeDirective, mirror logic in GCC: the system headerness of a file being entered can be set due to the #includer or the #includee. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@56688 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-11More #include cleaningDaniel Dunbar
- Kill unnecessary #includes in .cpp files. This is an automatic sweep so some things removed are actually used, but happen to be included by a previous header. I tried to get rid of the obvious examples and this was the easiest way to trim the #includes in one fell swoop. - We now return to regularly scheduled development. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54632 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-10Allow the preprocessor to cache the lexed tokens, so that we can do ↵Argyrios Kyrtzidis
efficient lookahead and backtracking. 1) New public methods added: -EnableBacktrackAtThisPos -DisableBacktrack -Backtrack -isBacktrackEnabled 2) LookAhead() implementation is replaced with a more efficient one. 3) LookNext() is removed. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54611 91177308-0d34-0410-b5e6-96231b3b80d8

2008-07-09Add Preprocessor::LookNext method, which implements an efficient way to ↵Argyrios Kyrtzidis
'take a peek' at the next token without consuming it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@53375 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-24Avoid overflowing buffer, patch by Algeris Kirtzidis!Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48741 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-15Make a major restructuring of the clang tree: introduce a top-levelChris Lattner
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48402 91177308-0d34-0410-b5e6-96231b3b80d8
