Author: ed Date: Mon Jun 14 06:23:47 2010 New Revision: 209153 URL: http://svn.freebsd.org/changeset/base/209153 Log: Unbreak Clang on PowerPC. It seems GCC 4.2.1 on PowerPC miscompiles Clang, causing it to crash when building even simple Hello World applications. Switch back to -O1 for this architecture.
