[FUG-BR] make.conf - CPUTYPE

[Joao Rocha Braga Filho]

Veja:

/usr/share/examples/etc/make.conf

"
# 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 athlon64 athlon-mp athlon-xp athlon-4
#                       athlon-tbird athlon k8 k6-3 k6-2 k6 k5 nocona
#       (Intel CPUs)    pentium4[m] prescott pentium3[m] pentium2 penitumpro
#                       pentium-mmx pentium i486 i386
#   Alpha/AXP architecture: ev67 ev6 pca56 ev56 ev5 ev45 ev4
#   AMD64 architecture: opteron, athlon64, nocona
#   Intel ia64 architecture: itanium2, itanium
#
# (?= allows to buildworld for a different CPUTYPE.)
#
#CPUTYPE?=i686
#NO_CPU_CFLAGS= true    # Don't add -march=<cpu> to CFLAGS automatically
#NO_CPU_COPTFLAGS=true  # Don't add -march=<cpu> to COPTFLAGS automatically
"

e:

man gcc

A princípio a sua escolha é boa.
