2010-09-28Centralize the management of CXXRecordDecl::DefinitionData's Empty bitDouglas Gregor
in CXXRecordDecl itself. Yes, this is also part of <rdar://problem/8459981>. This reinstates r114924, with one crucial bug fix: we were ignoring the implicit fields created by anonymous structs/unions when updating the bits in CXXRecordDecl, which means that a class/struct containing only an anonymous class/struct would be considered "empty". Hilarity follows. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@114980 91177308-0d34-0410-b5e6-96231b3b80d8

Centralize the management of CXXRecordDecl::DefinitionData's Aggregate and PlainOldData bits in CXXRecordDecl itself. Another milepost on the road toward <rdar://problem/8459981>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@114977 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-28Centralize the management of CXXRecordDecl::DefinitionData'sDouglas Gregor
HasTrivialConstructor, HasTrivialCopyConstructor, HasTrivialCopyAssignment, and HasTrivialDestructor bits in CXXRecordDecl's methods. This completes all but the Abstract bit and the set of conversion functions, both of which will require a bit of extra work. The majority of <rdar://problem/8459981> is now implemented (but not all of it). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@114929 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-27Kill FunctionDecl's IsCopyAssignment bit; it duplicated what couldDouglas Gregor
already be determined by isCopyAssignmentOperator(), and was set too late in the process for all clients to see the appropriate value. Cleanup only; no functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@114916 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-27Clean up the handling of the DeclaredDefaultConstructor andDouglas Gregor
DeclaredCopyConstructor bits in CXXRecordDecl's DefinitionData structure. Rather than having Sema call addedConstructor or set the bits directly at semi-random places, move all of the logic for managing these bits into CXXRecordDecl itself and tie the addedConstructor call into DeclContext::addDecl(). This makes it easier for AST-building clients to get the right bits set in DefinitionData, and is one small part of <rdar://problem/8459981>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@114889 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-24Default synthesized ivars don't really have a location in the source. Using ↵Ted Kremenek
the location of the @implementation is just confusing for clients that want to use SourceLocations for syntactic references. Fixes: <rdar://problem/8470540> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@114714 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-23Synchronize globally-cached code completion results with the resultsDouglas Gregor
provided when the optimization is disabled. In particular, split the completion context CCC_Other into two contexts: CCC_Other, which means that it's an undisclosed context for which any other results are unwelcome, and CCC_Recovery, which is used in recovery cases. Since we're now using the completion context within the completion results builder, make sure that it's always set to something. Fixes <rdar://problem/8470644>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@114704 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-23For properties declared in a @protocol and redeclared in a class extension, ↵Ted Kremenek

2010-09-21Correctly register the class extension as the lexical DeclContext for ObjC ↵Ted Kremenek
methods declared with @property in class extensions. This matches the behavior for setters. Also pass the class extension to ProcessPropertyDecl as the lexical DeclContext, even when not redeclaring the @property. This fixes the remaining issues in <rdar://problem/7410145>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@114477 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-21For ObjCPropertyDecls in class extensions, use the class extension as the ↵Ted Kremenek
lexical DeclContext for newly created ObjCMethodDecls. Further, use the location of the new property declaration as the location of new ObjCMethodDecls (if they didn't previously exist). This fixes more of the issues reported in <rdar://problem/7410145>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@114456 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-20Tweak priorities for some types and macros:Douglas Gregor

2010-09-18Problem with gnu conditional extension with missingFariborz Jahanian
LHS and when conditional expression is an array. Since it will be decayed, saved expression must be saved with decayed expression. This is necessary to preserve semantics of this extension (and prevent an IRGen crash which expects an array to always be decayed). I am sure there will be other cases in c++ (aggregate conditionals for example) when saving of the expression must happen after some transformation on conditional expression has happened.
