2012-03-02Ensure that we instantiate static reference data members of class templatesRichard Smith
early, since their values can be used in constant expressions in C++11. For odr-use checking, the opposite change is required, since references are odr-used whether or not they satisfy the requirements for appearing in a constant expression. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@151881 91177308-0d34-0410-b5e6-96231b3b80d8
2012-03-01c/objc: problem originally reported as an objective-c bug.Fariborz Jahanian
But it is in the underlying c part of clang. clang crashes in IRGen when passing an incomplete type argument to variadic function (instead of diagnosing the bug). // rdar://10961370 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@151862 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-01Implement "optimization" for lambda-to-block conversion which inlines the ↵Eli Friedman
generated block literal for lambdas which are immediately converted to block pointer type. This simplifies the AST, avoids an unnecessary copy of the lambda and makes it much easier to avoid copying the result onto the heap. Note that this transformation has a substantial semantic effect outside of ARC: it gives the converted lambda lifetime semantics similar to a block literal. With ARC, the effect is much less obvious because the lifetime of blocks is already managed. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@151797 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-26Special members which are defaulted or deleted on their first declaration areRichard Smith
trivial if the implicit declaration would be. Don't forget to set the Trivial flag on the special member as well as on the class. It doesn't seem ideal that we have two separate mechanisms for storing this information, but this patch does not attempt to address that. This leaves us in an interesting position where the has_trivial_X trait for a class says 'yes' for a deleted but trivial X, but is_trivially_Xable says 'no'.
