2008-09-04scan-build:Ted Kremenek
- Only set the environment variable 'CXX' if the user specifies --use-c++. - Fix regression when setting LDPLUSPLUS: add a 'which' to determine the location of g++.

2008-09-04Add some Objective-C code generation tests.Daniel Dunbar
- Note that these don't really test anything other than that code generation doesn't fail or crash. Better than nothing though! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55761 91177308-0d34-0410-b5e6-96231b3b80d8

2008-09-03Add __builtin_object_size support.Daniel Dunbar
- Currently CodeGen always returns a conservative value for this (-1 or 0 depending on the context). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55735 91177308-0d34-0410-b5e6-96231b3b80d8

2008-09-03Add semantic analysis for "blocks". Steve Naroff
Highlights... - 4 new AST nodes, BlockExpr, BlockStmtExpr, BlockExprExpr, BlockDeclRefExpr. - Sema::ActOnBlockStart(), ActOnBlockError(), ActOnBlockStmtExpr(), ActOnBlockExprExpr(), ActOnBlockReturnStmt(). Next steps... - hack Sema::ActOnIdentifierExpr() to deal with block decl refs. - add attribute handler for byref decls. - add test cases. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55710 91177308-0d34-0410-b5e6-96231b3b80d8

2008-09-03Improve type-checking of ?: for Objective-C types.Daniel Dunbar
- Allow any Objective-C object types to devolve to type id in a ?: expression. This matches gcc behavior more closely. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55705 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-03Store: (static analyzer)Ted Kremenek
- Change definition of store::Region and store::Binding (once again) to make them real classes that just wrap pointers. This makes them more strictly typed, and allows specific implementations of Regions/Bindings to just subclass them. - minor renamings to RegionExtent and its subclasses - added a bunch of doxygen comments StoreManager: (static analyzer) - added 'iterBindings', an iteration method for iterating over the bindings of a store. It that takes a callback object (acting like a poor man's closure). - added 'getRVal' version for store::Binding. Will potentially phase the other versions of GetRVal in StoreManager out. - reimplemented 'getBindings' to be non-virtual and to use 'iterBindings' BasicStoreManager: (static analyzer) - implemented 'iterBindings' for BasicStoreManager git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55688 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-03Restore Objective-C dot-syntax access of methods.Daniel Dunbar
- Now also searches for correct setter method. - There are still some issues regarding validation of the setter method and access of read-only properties. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55686 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-03Fix ObjCPropertRefExpr to be able to encode all the information forDaniel Dunbar
uses which refer to methods not properties. - Not yet wired in Sema. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55681 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-02When creating CXXRecordDecls and RecordDecls within ActOnTag, hook up the ↵Ted Kremenek
new [CXX]RecordDecl with the RecordDecl chain. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55652 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-02RecordDecl:Ted Kremenek
- Remove method 'isForwardDecl'; this functionality is already provided by 'isDefinition()' - Move method definitions to be co-located with other RecordDecl methods. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55649 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-02RecordDecl serialization:Ted Kremenek
- Don't serialize out the NextDeclarator field. It is unused and deprecated. - Serialize out the NextDecl pointer. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55644 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-02RecordDecl:Ted Kremenek
- Added method 'isForwardDeclaration', a predicate method that returns true if a RecordDecl represents a forward declaration. - Added method 'getDefinitionDecl', a query method that returns a pointer to the RecordDecl that provides the actual definition of a struct/union. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55642 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-02CXXRecordDecl and RecordDecl:Ted Kremenek
- Change constructor and create methods to accept a CXXRecordDecl* (RecordDecl*) instead of a ScopedDecl* for PrevDecl. This causes the type checking to be more tight and doesn't break any code. RecordDecl: - Don't use the NextDeclarator field in ScopedDecl to represent the previous declaration. This is a conflated use of the NextDeclarator field, which will be removed anyway when DeclGroups are fully implemented. - Instead, represent (a soon to be implemented) chain of RecordDecls using a NextDecl field. The last RecordDecl in the chain is always the 'defining' RecordDecl that owns the FieldDecls. The other RecordDecls in the chain are forward declarations. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55640 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-02- Implement __block.Steve Naroff
- Replace FIXME in Preprocessor::HandleIdentifier() with a check that avoids diagnosing extension tokens that originate from macro definitions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55639 91177308-0d34-0410-b5e6-96231b3b80d8

2008-09-02Fix for PR2747: allow pointer->int casts with a null base; these are Eli Friedman
offset-of-like expressions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55627 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-02Fix for PR2750; don't check for an 'e' in the trash after the token.Eli Friedman
Note that this isn't really a complete fix; I think there are other potential overrun situations. I don't really know what the best systematic fix is, though. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55622 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-02An extremely hacky version of transparent_union support; it isn't Eli Friedman
anywhere near correct in terms of missing cases and missing diagnostics, but it's good enough to handle the uses in the Linux system headers, which are currently a constant pain for compiling applications on Linux. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55621 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-02Make sure to take the unqualified versions of the canonical types for Eli Friedman
type-checking pointer subtraction; if the canonical types aren't used, the qualifiers won't always get stripped off correctly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55620 91177308-0d34-0410-b5e6-96231b3b80d8
