Previously, compiler warned only if it was unsafe if types did not match. Fixes // rdar: //7933061 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@115683 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-05Register the __builtin_va_list_type node when we parse it, rather thanDouglas Gregor
waiting until we think we need it: we didn't catch all of the places where we actually needed it, and we probably wouldn't ever. Fixes a C++ PCH crasher. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@115621 91177308-0d34-0410-b5e6-96231b3b80d8

2010-10-02When providing a block literal as a code completion for aDouglas Gregor
function/method argument, include the parameter name and always include parentheses (even for zero-parameter blocks). Otherwise, the block literal placeholder '^' can look very weird. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@115444 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-29Move the management of the set of conversion functions in a C++ classDouglas Gregor
into CXXRecordDecl. The only part that we do not handle this way are using declarations, since that would require extra name lookup that we don't currently want to pay for. This fixes <rdar://problem/8459981>, so that LLDB can build a CXXRecordDecl and magically get all of the right bits set. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@115026 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-29Move the maintenance of CXXRecordDecl::DefinitionData's Abstract bitDouglas Gregor
completely into CXXRecordDecl, by adding a new completeDefinition() function. This required a little reshuffling of the final-overrider checking code, since the "abstract" calculation in the presence of abstract base classes needs to occur in CXXRecordDecl::completeDefinition() but we don't want to compute final overriders more than one in the common case. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@115007 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-28Teach FunctionDecl::setPure() to (indirectly) mark the Abstract bit inDouglas Gregor
CXXRecordDecl::DefinitionData, rather than having Sema mark the bit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@114993 91177308-0d34-0410-b5e6-96231b3b80d8

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
2010-09-28Move ExternalSemaSource::ReadMethodPool's implementation to Sema.cpp so that ↵Sebastian Redl
the header can get away with forward declarations only for ObjCMethodList and Selector. Fixes <rdar://8467631>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@114978 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

HasTrivialConstructor, HasTrivialCopyConstructor, HasTrivialCopyAssignment, and HasTrivialDestructor bits in CXXRecordDecl's methods.

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

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.
