Author: filcab Date: Sat Jul 18 01:35:24 2015 New Revision: 242606 URL: http://llvm.org/viewvc/llvm-project?rev=242606&view=rev Log: Silence the driver warnings, if we see "-w" on the Driver.
Summary: We can enable warnings after that -w, so the patch might not be 100% correct. The problem that triggered this is: we have some amount of tests that expect 0 warnings (including unit tests for -w), but -w ends up not fully silencing everything.
