Ok, it survived a buildworld on the DS20 (with EV6's) ok. I updated it and also patched the 8- and 16-bit versions in atomic.s as well. The patch is at ~jhb/public_html/patches/alpha.patch on freefall. Feel free to commit it since you did the brunt of the work. FWIW, it didn't seem to make a noticable difference in world time. -- John Baldwin <jhb@FreeBSD.org> <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve!" - http://www.FreeBSD.org/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe cvs-all" in the body of the message
