Hi!

 ftp://ppc.linux.or.jp/pub/users/fukui

There are newer binutils and gcc-3.1.pre.
Those have Altivec instruction.
gcc-3.1 will be switch to altivec with -maltivec.

But If you want to altivec code,
It need the source which is written by altivec register.
See www.altivec.org about altivec.

Anyway, Try to write simple c source.
Then

gcc -S simple.c

You get simple.s

The simple.s is written by asmppc.
