[cfe-commits] r67258 - /cfe/trunk/include/clang/Parse/Ownership.h

[Gabor Greif]

New Revision: 67258

URL: http://llvm.org/viewvc/llvm-project?rev=67258&view=rev
Log:
Add a sugared version of ASTOwningResult::take,
that does a downcast. It is named takeAs<T>().
The plain-pointer version is also added, but
that side seems to be seriously bitrotten.
