2013-04-26Add r180263 back, but fix hasBraces() to be correct during parsing.Rafael Espindola
Original commit message: Fix a case in linkage computation that should check for single line extern "C". git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@180591 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-25Put friend decls in the correct context.Rafael Espindola
When we find a friend declaration we have to skip transparent contexts for doing lookups, but we should not skip them when inserting the new decl if the lookup found nothing. Fixes PR15841. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@180571 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-22C++1y constexpr extensions, round 1: Allow most forms of declaration andRichard Smith
statement in constexpr functions. Everything which doesn't require variable mutation is also allowed as an extension in C++11. 'void' becomes a literal type to support constexpr functions which return 'void'. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@180022 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-20C++1y: Allow aggregates to have default initializers.Richard Smith
Add a CXXDefaultInitExpr, analogous to CXXDefaultArgExpr, and use it both in CXXCtorInitializers and in InitListExprs to represent a default initializer. There's an additional complication here: because the default initializer can refer to the initialized object via its 'this' pointer, we need to make sure that 'this' points to the right thing within the evaluation. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@179958 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-10Add support for computing the exception specification for an inheritingRichard Smith
constructor. This isn't quite perfect (as usual, we don't handle default arguments correctly yet, and we don't deal with copy/move constructors for arguments correctly either, but this will be fixed when we implement core issue 1351.

2013-04-03Don't compute a patched/semantic storage class.Rafael Espindola
For variables and functions clang used to store two storage classes. The one "as written" in the code and a patched one, which, for example, propagates static to the following decls. This apparently is from the days clang lacked linkage computation. It is now redundant and this patch removes it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@178663 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-26<rdar://problem/13267210> Ensure that Sema::CompareReferenceRelationship ↵Douglas Gregor
returns consistent results with invalid types. When Sema::RequireCompleteType() is given a class template specialization type that then fails to instantiate, it returns 'true'. On subsequent invocations, it can return false. Make sure that this difference doesn't change the result of Sema::CompareReferenceRelationship, which is expected to remain stable while we're checking an initialization sequence. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@178088 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-22[Sema] Semantic analysis for empty-declaration and attribute-declaration.Michael Han
Introduce a new AST Decl node "EmptyDecl" to model empty-declaration.

2013-02-18Replace TypeLoc llvm::cast support to be well-defined.David Blaikie
The TypeLoc hierarchy used the llvm::cast machinery to perform undefined behavior by casting pointers/references to TypeLoc objects to derived types and then using the derived copy constructors (or even returning pointers to derived types that actually point to the original TypeLoc object). Some context is in this thread: http://lists.cs.uiuc.edu/pipermail/llvmdev/2012-December/056804.html Though it's spread over a few months which can be hard to read in the mail archive. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@175462 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-30Provide a fixit for constexpr non-static data members.David Blaikie
If the member has an initializer, assume it was probably intended to be static and suggest/recover with that. If the member doesn't have an initializer, assume it was probably intended to be const instead of constexpr and suggest that. (if the attempt to apply these changes fails, don't make any suggestion & produce the same diagnostic experience as before. The only case where this can come up that I know of is with a mutable constexpr with an initializer, since mutable is incompatible with static (but it's already incompatible with const anyway)) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173873 91177308-0d34-0410-b5e6-96231b3b80d8
