Re: RE: Machines are getting too damn fast
: :This explained in great detail exactly why people are seeing the performance :they are from the P4 etc. The author knows his stuff. : :http://www.emulators.com/pentium4.htm : :Brandon Heh heh.

Noted. Is there a gcc PR associated with this? http://gcc.gnu.org/cgi-bin/gnatsweb.pl A GNATS searc for "freebsd kernel" didn't return anything. -Charles -Original Message- From: Matt Dillon [mailto:[EMAIL PROTECTED]] Sent: Tuesday, March 06, 2001 11:44 AM To: Charles Randall Cc: Andrew Gallatin; [EMAIL PROTECTED] Subject: Re: RE: Machines are getting too damn fast :Which begs the question I've tried to ask a number of times in different :forums.

Somewhere around 4.1 my -O2 and -Os kernel compiles just stopped working. There was a bunch of stuff on the list about it. -Matt To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message
