My experience with optimization under NetBSD/sun3 is not good.

Specifically, under 1.1's gcc, you have to turn off optimization for
the kernel - or at least for that file.  But under 1.2, you have to
turn optimization _on_, or what happens, I think the compiler silently
bugchecks (cc1 dies with SIGABRT, IIRC).

I haven't sent-pr this because the sun3 systems are in a state of
sufficient flux that I don't have a system on which to build the latest
sup and see if that fixes it, and a sup over a month old is a bit stale
to report PRs relative to.
