(It has > been FreeBSD's default on 5.x and 6.x for ages.) Personally, I don't consider -O2 safe for kernel builds on the gcc-3 shipped with FreeBSD. On a FreeBSD-6 box I had annoying sound glitches every now and then[1] which disappeared when reverting to -O for the kernel. I would be surprised if there weren't any other issues. Riggs [1] That was on a laptop with onboard sound and 6.0, more than a year ago and I haven't built another -O2 kernel since I noticed that behaviour, so I can't say if it's still a problem with current releases. -- - Now the world has gone to bed | Now I lay me down to sleep - -- Darkness won't engulf my head | Try to count electric sheep -- --- I can see by infra-red | Sweet dream wishes you can keep --- ---- How I hate the night | How I hate the night ----
