Author: nico Date: Fri Sep 18 15:49:33 2015 New Revision: 248034 URL: http://llvm.org/viewvc/llvm-project?rev=248034&view=rev Log: clang-cl: Don't warn on /bigobj flag
LLVM r217812 made it so that clang-cl implicitly creates bigobj files when needed, independent of this flag. It looks like cl has this flag to produce obj flags compatible with MSVS 2003's linker by default, something we don't care about. Since clang-cl always has /bigobj behavior, don't warn that the flag is unused, just ignore it silently.
