2009-01-09Move property API's up to ObjCContainerDecl (removing a lot of duplicate code).Steve Naroff
Add isa/cast/dyncast support for ObjCContainerDecl. Renamed classprop_iterator/begin/end to prop_iterator/begin/end (the class prefix was confusing). More simplifications to Sema::ActOnAtEnd()... Added/changed some FIXME's as a result of the above work. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@61988 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-09Addressed the issue in <rdar://problem/6479085>, where we failed toDouglas Gregor
rewrite @class declarations that showed up within linkage specifications because those @class declarations never made it any place where the rewriter could find them. Moved all of the ObjC*Decl nodes over to ScopedDecls, so that they can live in the appropriate top-level or transparent DeclContext near the top level, e.g., TranslationUnitDecl or LinkageSpecDecl. Objective-C declarations now show up in a traversal of the declarations in a DeclContext (they didn't before!). This way, the rewriter finds all Objective-C declarations within linkage specifications. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@61966 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-08This is a large/messy diff that unifies the ObjC AST's with DeclContext.Steve Naroff
- ObjCContainerDecl's (ObjCInterfaceDecl/ObjCCategoryDecl/ObjCProtocolDecl), ObjCCategoryImpl, & ObjCImplementation are all DeclContexts. - ObjCMethodDecl is now a ScopedDecl (so it can play nicely with DeclContext). - ObjCContainerDecl now does iteration/lookup using DeclContext infrastructure (no more linear search:-) - Removed ASTContext argument to DeclContext::lookup(). It wasn't being used and complicated it's use from an ObjC AST perspective. - Added Sema::ProcessPropertyDecl() and removed Sema::diagnosePropertySetterGetterMismatch(). - Simplified Sema::ActOnAtEnd() considerably. Still more work to do. - Fixed an incorrect casting assumption in Sema::getCurFunctionOrMethodDecl(), now that ObjCMethodDecl is a ScopedDecl. - Removed addPropertyMethods from ObjCInterfaceDecl/ObjCCategoryDecl/ObjCProtocolDecl. This passes all the tests on my machine. Since many of the changes are central to the way ObjC finds it's methods, I expect some fallout (and there are still a handful of FIXME's). Nevertheless, this should be a step in the right direction. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@61929 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-05Introduce support for "transparent" DeclContexts, which areDouglas Gregor
DeclContexts whose members are visible from enclosing DeclContexts up to (and including) the innermost enclosing non-transparent DeclContexts. Transparent DeclContexts unify the mechanism to be used for various language features, including C enumerations, anonymous unions, C++0x inline namespaces, and C++ linkage specifications. Please refer to the documentation in the Clang internals manual for more information. Only enumerations and linkage specifications currently use transparent DeclContexts. Still to do: use transparent DeclContexts to implement anonymous unions and GCC's anonymous structs extension, and, later, the C++0x features. We also need to tighten up the DeclContext/ScopedDecl link to ensure that every ScopedDecl is in a single DeclContext, which will ensure that we can then enforce ownership and reduce the memory footprint of DeclContext. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@61735 91177308-0d34-0410-b5e6-96231b3b80d8

2008-12-23PTH:Ted Kremenek
- Embed 'eom' tokens in PTH file. - Use embedded 'eom' tokens to not lazily generate them in the PTHLexer. This means that PTHLexer can always advance to the next token after reading a token (instead of buffering tokens using a copy). - Moved logic of 'ReadToken' into Lex. GetToken & ReadToken no longer exist. - These changes result in a 3.3% speedup (-Eonly) on Cocoa.h. - The code is a little gross. Many cleanups are possible and should be done. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@61360 91177308-0d34-0410-b5e6-96231b3b80d8
2008-12-23Don't explicitly represent OverloadedFunctionDecls withinDouglas Gregor
DeclContext. Instead, just keep the list of currently-active declarations and only build the OverloadedFunctionDecl when we absolutely need it. This is a half-step toward eliminating the need to explicitly build OverloadedFunctionDecls that store sets of overloaded functions. This was suggested by Argiris a while back, and it's a good thing for several reasons: first, it eliminates the messy logic that currently tries to keep the OverloadedFunctionDecl in sync with the declarations that are being added. Second, it will (eventually) eliminate the need to allocate memory for overload sets, which could help performance. Finally, it helps set us up for when name lookup can return multiple (possibly ambiguous) results, as can happen with lookup of class members in C++. Next steps: make the IdentifierResolver store overloads as separate entries in its list rather than replacing them with an OverloadedFunctionDecl now, then see how far we can go toward eliminating OverloadedFunctionDecl entirely. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@61357 91177308-0d34-0410-b5e6-96231b3b80d8

- Added a side-table per each token-cached file with the preprocessor conditional stack. This tracks what #if's are matched with what #endifs and where their respective tokens are in the PTH file.

2008-12-11Unifies the name-lookup mechanisms used in various parts of the ASTDouglas Gregor
and separates lexical name lookup from qualified name lookup. In particular: * Make DeclContext the central data structure for storing and looking up declarations within existing declarations, e.g., members of structs/unions/classes, enumerators in C++0x enums, members of C++ namespaces, and (later) members of Objective-C interfaces/implementations. DeclContext uses a lazily-constructed data structure optimized for fast lookup (array for small contexts, hash table for larger contexts). * Implement C++ qualified name lookup in terms of lookup into DeclContext. * Implement C++ unqualified name lookup in terms of qualified+unqualified name lookup (since unqualified lookup is not purely lexical in C++!) * Limit the use of the chains of declarations stored in IdentifierInfo to those names declared lexically. * Eliminate CXXFieldDecl, collapsing its behavior into FieldDecl. (FieldDecl is now a ScopedDecl). * Make RecordDecl into a DeclContext and eliminates its Members/NumMembers fields (since one can just iterate through the DeclContext to get the fields). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@60878 91177308-0d34-0410-b5e6-96231b3b80d8
