I've been running a -O2 world for a couple of weeks, just to see if it made any difference. The kernel went up from about 650k to about 750k, so I guess some inlining is happening. There were one or two compiler crashes, but I think I've got a dodgey memory system: I'm running without an L2 cache at the moment, which helps. From memory, there's just one file (a yacc parser, I think. Could even be groff) that causes gcc to break on -O2, and has to be compiled at -O. -- Andrew "The steady state of disks is full." -- Ken Thompson To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
