Interesting and more than I understand. For example:
man make.conf I find:
CPUTYPE (str) Controls which processor should be targeted for
gen-
erated code. This controls processor-specific optimiza-
tions in certain code (currently only OpenSSL) as well as
modifying the value of CFLAGS and COPTFLAGS to contain
the
appropriate optimization directive to gcc(1). The auto-
matic setting of CFLAGS and COPTFLAGS may be overridden
using the NO_CPU_CFLAGS and NO_CPU_COPTFLAGS variables,
respectively. Refer to /usr/share/examples/etc/make.conf
for a list of recognized CPUTYPE options.
in /usr/share/examples/etc/make.conf I find:
# The CPUTYPE variable controls which processor should be targeted for
# generated code. This controls processor-specific optimizations in
# certain code (currently only OpenSSL) as well as modifying the value
# of CFLAGS to contain the appropriate optimization directive to gcc.
# The automatic setting of CFLAGS may be overridden using the
# NO_CPU_CFLAGS variable below.
# Currently the following CPU types are recognized:
# Intel x86 architecture:
# (AMD CPUs) opteron-sse3 opteron athlon64-sse3 athlon64
athlon-mp
# athlon-xp athlon-4 athlon-tbird athlon k8-sse3 k8
# geode k6-3 k6-2 k6 k5
# (Intel CPUs) core2 core nocona pentium4m pentium4 prescott
# pentium3m pentium3 pentium-m pentium2
# pentiumpro pentium-mmx pentium i486 i386
# (Via CPUs) c3 c3-2
# AMD64 architecture: opteron, athlon64, nocona, prescott, core2
# Intel ia64 architecture: itanium2, itanium
# SPARC-V9 architecture: v9 (generic 64-bit V9), ultrasparc (default
# if omitted), ultrasparc3
So I check my dmesg says:
FreeBSD 9.0-STABLE #160 r229960M: Sat May 26 05:08:37 CDT 2012

I'm sure one of the options in make.conf would probably work but I think
forgetting about Chrome is much easier and EMO not a big deal. I seldom us
it.
Thanks for the help. Sorry for the noise and for not being able to
translate between make.conf, and dmesg. Have a great day.
