<x-tad-bigger>Remember, the only difference between a G3 and a G4 is Altivec. Altivec is a specialized vector processor and only a small number of specific software tasks in some applications actually utilize it. The majority of mainstream applications do not take advantage of Altivec. Even the Darwin kernel, at the heart of Mac OS X, is not optimized to use Altivec.

Here on a 450 MHz G3, I've been using these flags for many
months with no
problems:
CFLAGS="-O3 -mcpu=G3 -maltivec -mabi=altivec
-fno-strict-aliasing -pipe"
Does the G3 have altivec extensions? I thought that they didn't
show up till
the G4.
man dont tell me that! i was going with what the guy said and
have almost completed the entire bootstrap with those cflags! i
hope your wrong.....(no offense of course)

If I recall correctly, it won't kill any thing. It might slow somethings
down. I just don't know for sure. The -mabi might cause problems with
compatibly with precompiled modules.
The best thing would be to look it up. I'm no expert on the PPC, but I
believe that I am correct in this.
