There is test code for SSE.
(2001/01/26)It seem to harmless with mendocino celeron.
(2001/02/09)There is a mail from
Mr. KATO @aist.go.jp. Thanks a lot.
(2001/03/03)I confirmed that SSE instructions can use with single
cuppermine celeron.
(2001/05/05)make patch for 4.3R.
(2001/05/15)Mr. KATO's WWW page was moved from okayama-u.ac.jp.
(2001/06/11)I made a patch for 5-current. I checked only single
cuppermine celeron. SMP is not tested yet.
(2001/06/30)ohashi@kyutech reports me that Pentium4 on FreeBSD4.3 works fine.
Thanks!
(2001/08/18)My SSE patches have been merged into FreeBSD -current and -stable.
My send-pr: kern/28070 have been closed. And I added SSE2 test code to loop.C .
But I can't test it, because I don't have Pentium4.
(2001/10/06)I confirmed that AthlonXP can use SSE even in SMP environment.
I tested dual AthlonXP/1.33GHz. It's VERY fast!
