Please see cvsweb:
...and search for "-O2". Seems to have been first enabled on the AMD64
platform in v1.45, and on i386 since v1.6:

While we're building kernels -g (ie, makeoptions DEBUG=-g), use -O as it
provides truer debugger stack traces. For those that want to stick with
-O2 kernel builds, one should probably add -fno-optimize-sibling-calls
so that each stack frame as a frame pointer.
It is semi-promissed by the Release Engineers that when RELENG_6 is
created we go back to -O2.

Don the teflon coated jacket and use the same -O2 optimization options on
the 'i386' kernel that we do all our 64-bit kernels.
