Author: tberghammer Date: Fri Oct 23 05:34:53 2015 New Revision: 251107 URL: http://llvm.org/viewvc/llvm-project?rev=251107&view=rev Log: Disable the strict-aliasing warnings produced by gcc
GCC produce a lot of strict-aliasing warning for the LLDB codebase what makes reading the compile output very difficult. This change disable these warnings to reduce the noise as we already ignore them. We should consider re-enabling the warning if we fix all (or most) strict-aliasing violation first.
