Author: rpaulo Date: Tue Sep 21 20:23:19 2010 New Revision: 212976 URL: http://svn.freebsd.org/changeset/base/212976 Log: Workaround LLVM bug #4434: Reorder inline assembly arguments temp2, temp, value and texp to follow the st(0), st(1), etc. style. Also mark the temp2 variable as volatile to workaround another clang bug. This allows clang to buildworld FreeBSD/i386.
