2008-08-17various updates to match r54873 on mainline.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54874 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-14Change Parser & Sema to use interned "super" for comparions.Daniel Dunbar
- 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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54794 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-12Move some ObjC preprocessor definitions intoDaniel Dunbar
InitializePredefinedMacros(). - Also now properly wired to -fobjc-gc, -fnext-runtime. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54661 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-11remove obsolete comment.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54652 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
2008-08-10* Remove isInSystemHeader() from DiagClient, move it to SourceManagerNico Weber
* Move FormatError() from TextDiagnostic up to DiagClient, remove now empty class TextDiagnostic * Make DiagClient optional for Diagnostic This fixes the following problems: * -html-diags (and probably others) does now output the same set of warnings as console clang does * nothing crashes if one forgets to call setHeaderSearch() on TextDiagnostic * some code duplication is removed git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54620 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

when targeting the new, Apple 2.0 *runtime ABI*. It is not intended to be used to #ifdef ObjC 2.0 langauge features. This is unfortunate (given it's name).

2008-05-05Neil pointed out that clang doesn't generate ranges from diagnosticsChris Lattner
related to pp-expressions.

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
