Author: nwhitehorn Date: Sun Jan 1 15:56:15 2012 New Revision: 229169 URL: http://svn.freebsd.org/changeset/base/229169 Log: Instead of forcing -O1 on PowerPC for LLVM and clang, fix the actual problem by adding -fno-strict-aliasing to CFLAGS. Since this is a global issue that just happened to manifest on PowerPC, add this to CFLAGS unconditionally.
