[cfe-commits] [libcxx] r113294 - in /libcxx/trunk: include/type_traits test/utilities/meta/meta.unary/meta.unary.prop/has_nothrow_copy_constructor.pass.cpp

New Revision: 113294

URL: http://llvm.org/viewvc/llvm-project?rev=113294&view=rev
Log:
has_nothrow_copy_constructor hooked up to clang.  Filed http://llvm.org/bugs/show_bug.cgi?id=8107 to take care of several types which don't work yet.  If there is some reason we don't want to handle these types in the compiler, I can handle most of them in the library.
