Author: marcel Date: Wed Oct 21 18:09:48 2009 New Revision: 198338 URL: http://svn.freebsd.org/changeset/base/198338 Log: o Align function on a 32-byte boundary so that the core's front-end can deliver 2 bundles per cycle to the back-end. o Mark syscall stubs with a special unwind ABI tag so that unwind libraries know how to unwind.
