Hello,
can someone tell what the right choice for CPUTYPE in /etc/make.conf
is for that CPU?
CPUTYPE?=pentium2
CFLAGS+= -mtune=prescott
COPTFLAGS+= -mtune=prescott
I find that this produces faster, and safer, code then
-march=pentium4, etc. alone. you can view all the gcc flags here:
http://gcc.gnu.org/onlinedocs/gcc-3.4.6/gcc/i386-and-x86_002d64-Options.html
And, is it safe to build kernel and world with --march= too?
With the gcc options I gave to you above yes.
