2013-05-21Merging r182266:Bill Wendling
------------------------------------------------------------------------ r182266 | rnk | 2013-05-20 07:02:37 -0700 (Mon, 20 May 2013) | 13 lines Implement __declspec(selectany) under -fms-extensions selectany only applies to externally visible global variables. It has the effect of making the data weak_odr. The MSDN docs suggest that unused definitions can only be dropped at linktime, so Clang uses weak instead of linkonce. MSVC optimizes away references to constant selectany data, so it must assume that there is only one definition, hence weak_odr.

2013-05-06Fix representation of compound literals for C++ objects with destructors.Jordan Rose
Previously, this compound literal expression (a GNU extension in C++): (AggregateWithDtor){1, 2} resulted in this AST: `-CXXBindTemporaryExpr [...] 'struct Point' (CXXTemporary [...]) `-CompoundLiteralExpr [...] 'struct AggregateWithDtor' `-CXXBindTemporaryExpr [...] 'struct AggregateWithDtor' (CXXTemporary [...]) `-InitListExpr [...] 'struct AggregateWithDtor' |-IntegerLiteral [...] 'int' 1 `-IntegerLiteral [...] 'int' 2 Note the two CXXBindTemporaryExprs. The InitListExpr is really part of the CompoundLiteralExpr, not an object in its own right. By introducing a new entity initialization kind in Sema specifically for compound literals, we avoid the treatment of the inner InitListExpr as a temporary. `-CXXBindTemporaryExpr [...] 'struct Point' (CXXTemporary [...]) `-CompoundLiteralExpr [...] 'struct AggregateWithDtor' `-InitListExpr [...] 'struct AggregateWithDtor' |-IntegerLiteral [...] 'int' 1 `-IntegerLiteral [...] 'int' 2 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@181212 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

2013-04-17Add a bit of a hack to deal with a failing testcase on darwin10 bots.Eric Christopher
We currently emit an error message when you try to use thread local storage on targets that don't support it and testing C++11 thread locals will trip this. We don't want to xfail the test for all darwin hosts so add a quick hack to check for darwin10 and disable the test based on that. Only checking darwin10 because anything earlier is really old and I don't have a list of what other hosts don't support tls handy.
