New Revision: 45103

URL: http://llvm.org/viewvc/llvm-project?rev=45103&view=rev
Log:
Added driver option -Wno-format-nonliteral to silence format string related
warnings. This flag is the inverse of to GCC's -Wformat-nonliteral option (in
the clang driver, these warnings are on by default).

Patch provided by Shantonu Sen.
