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.
