Author: marius Date: Thu Dec 30 15:58:23 2010 New Revision: 216820 URL: http://svn.freebsd.org/changeset/base/216820 Log: - Add CPUTYPE support for sparc64. The net result is that it's now possible to let the compiler optimize for the famility of UltraSPARC-III CPUs as the default already was to optimize for UltraSPARC-I/II and generating generic 64-bit V9 is mainly for reference purposes. At least for SPARC64-V CPUs code optimized for UltraSPARC-I/II still is the most performant one. Thanks go to Michael Moll for testing SPARC64-V. - Move a booke MACHINE_CPU bit into the right section.
