This is because these optimisations are known to break the FreeBSD

I have set CPUTYPE=p3 in make.conf. When I compile my kernel I see
-march=pentium3 as I expect. I also see -mno-mmx and -mno-sse are set
which I do not expect given that -march=pentium3 is used. I presume
that I want MMX and SSE since my processor supports it. What options do
I set and
From /usr/src/sys/conf/kern.mk:
# On the i386, do not align the stack to 16-byte boundaries. Otherwise GCC
# 2.95 adds code to the entry and exit point of every function to align the

stack
