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.
