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

2008-03-09rename the MacroExpander class to TokenLexer. It handles bothChris Lattner
token streams and macro lexing, so a more generic name is useful. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48071 91177308-0d34-0410-b5e6-96231b3b80d8

2008-03-05Remove the first layer of support for "portability" warnings. This is Chris Lattner
theoretically useful, but not useful in practice. It adds a bunch of complexity, and not much value. It's best to nuke it. One big advantage is that it means the target interfaces will soon lose their SLoc arguments and target queries can never emit diagnostics anymore (yay). Removing this also simplifies some of the core preprocessor which should make it slightly faster. Ted, I didn't simplify TripleProcessor, which can now have at most one triple, and can probably just be removed. Please poke at it when you have time. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@47930 91177308-0d34-0410-b5e6-96231b3b80d8

2008-02-16Fix CheckEndOfDirective to diagnose lines that contain macros that expand to Chris Lattner
zero tokens. This fixes PR2045, thanks to Neil for finding another incredibly subtle corner case :) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@47203 91177308-0d34-0410-b5e6-96231b3b80d8
2008-02-11Move Microsoft __declspec hack from the parser to the preprocessor. Since we ↵Steve Naroff
have no plans to actually implement this construct, it is cleaner to limit the change to the preprocessor. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@46973 91177308-0d34-0410-b5e6-96231b3b80d8

2008-02-07Minor cleanup from yesterday's -fms-extension commit. Move __int* MS ↵Steve Naroff
keywords to predefined macros. This removes some of the MS-madness from Parser::ParseDeclarationSpecifiers(). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@46852 91177308-0d34-0410-b5e6-96231b3b80d8
2008-02-07Implement support for the extremely atrocious MS /##/ extension, Chris Lattner
which pastes together a comment. This is only enabled with -fms-extensions of course. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@46845 91177308-0d34-0410-b5e6-96231b3b80d8
2008-02-07Implement -fms-extensions. This allows us to fuzzy parse non-standard MS ↵Steve Naroff

noticing this! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@46256 91177308-0d34-0410-b5e6-96231b3b80d8

2008-01-07Fix a nasty corner case that Neil noticed in PR1900, where we would Chris Lattner
incorrectly apply the multiple include optimization to files with guards like: #if !defined(x) MACRO where MACRO could expand to different things in different contexts. Thanks Neil! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45716 91177308-0d34-0410-b5e6-96231b3b80d8

2007-12-29Don't attribute in file headers anymore. See llvmdev for theChris Lattner
discussion of this change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45410 91177308-0d34-0410-b5e6-96231b3b80d8
2007-12-19Interned MainFileID within SourceManager. Since SourceManager is referenced byTed Kremenek
both Preprocessor and ASTContext, we no longer need to explicitly pass MainFileID around in function calls that also pass either Preprocessor or ASTContext. This resulted in some nice cleanups in the ASTConsumers and the driver. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45228 91177308-0d34-0410-b5e6-96231b3b80d8
2007-12-12TargetInfo no longer includes a reference to SourceManager.Ted Kremenek
Moved all clients of Diagnostics to use FullSourceLoc instead of SourceLocation. Added many utility methods to FullSourceLoc to provide shorthand for: FullLoc.getManager().someMethod(FullLoc.getLocation()); instead we have: FullLoc.someMethod(); Modified TextDiagnostics (and related classes) to use this short-hand. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44957 91177308-0d34-0410-b5e6-96231b3b80d8
2007-12-11Mega-patch: ripped SourceManager out of Diagnostic/DiagnosticClient. NowTed Kremenek
SourceManager is passed by reference, allowing the SourceManager to be associated with a specific translation unit, and not the entire execution of the driver. Modified all users of Diagnostics to comply with this new interface. Integrated SourceManager as a member variable of TargetInfo. TargetInfo will eventually be associated with a single translation unit (just like SourceManager). Made the SourceManager reference in ASTContext private. Provided accessor getSourceManager() for clients to use instead. Modified clients to comply with new interface. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44878 91177308-0d34-0410-b5e6-96231b3b80d8

info of each token. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44741 91177308-0d34-0410-b5e6-96231b3b80d8

2007-11-10Since we are all working on Leopard, change the built-in MacOS X version ↵Steve Naroff
number (__ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__) to target Leopard. This is only a short term solution, until the clang driver implements the "-mmacosx-version-min" flag (which will compute this value based on the target). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@43981 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-31Implement a more sensible strategy for ObjC built-in types (addressing a ↵Steve Naroff
long standing FIXME in Sema::GetObjcIdType()). This removes several gross hacks to work around the previous "lazy" behavior. Two notes: - MinimalActions still needs to be taught about the built-in types (This breaks one of the -noop test cases). I started this, then added a FIXME. - I didn't convert Sema::GetObjcProtoType() yet. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@43567 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-31Checking in some code that is still under construction.Steve Naroff
I need to (finally) change the way Class/id/SEL/IMP are built-in...the current approach of doing it in the preprocessor is "broken". The other problem is Sema::GetObjcIdType/GetObjcSelType/GetObjcClassType, the hooks that initialize ASTContext lazily. These built-in types need to be done up front... git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@43557 91177308-0d34-0410-b5e6-96231b3b80d8

2007-10-30Stop pre-defining objc_msgSend/objc_getClass in the preprocessor. Instead, I ↵Steve Naroff
generate these declaration on the fly when rewriting a message expression. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@43529 91177308-0d34-0410-b5e6-96231b3b80d8

2007-10-17Predefine all the ObjC goodies from <objc/objc.h>. Removed all the ObjC ↵Steve Naroff
goodies from the respective test files. Moving forward, it will be very nice to assume these builtin! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@43077 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-10resolve a fixme, by moving __builtin_va_list to a more logicalChris Lattner

2007-10-09Make a significant change to invert the control flow handlingChris Lattner
predefined macros. Previously, these were handled by the driver, now they are handled by the preprocessor. Some fallout of this: 1. Instead of preprocessing two buffers (the predefines, then the main source file) we now start preprocessing the main source file and inject the predefines as a "psuedo #include" from the main source file. 2. #1 allows us to nuke the Lexer::IsMainFile flag and simplify Preprocessor::isInPrimaryFile. 3. The driver doesn't have to know about standard #defines, the preprocessor knows, which is nice for people wanting to define their own drivers. 4. This allows us to put normal tokens in the predefine buffer, for example a definition for __builtin_va_list that is target-specific, and a typedef for id in objc. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@42818 91177308-0d34-0410-b5e6-96231b3b80d8

2007-10-07improve layering:Chris Lattner
Now instead of IdentifierInfo knowing anything about MacroInfo, only the preprocessor knows. This makes MacroInfo truly private to the Lex library (and its direct clients) instead of being accessed in the Basic library. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@42727 91177308-0d34-0410-b5e6-96231b3b80d8
