New Revision: 259598

URL: http://llvm.org/viewvc/llvm-project?rev=259598&view=rev
Log:
Work around build failure due to GCC 4.8.1 bug. We don't completely understand
the details of the bug, but avoiding overloading llvm::cast with another
function template sidesteps it.

See gcc.gnu.org/PR58022 for details of the bug, and llvm.org/PR26362 for more
backgound on how it manifested in Clang. Patch by Igor Sugak!
