altivec intrinsics:


#include <vmx2spu.h>

[spu specific way to get data]

[former altivec code here, unchanged]

[spu specific way to push data]


The altivec code would just build for spu thanks to the altivec/vmx ->
spu mapping header.

asm :

reread what you wrote

rewrite it

Obviously you could refactor the code to use some spu-only constructs
you may deem useful, BUT most of the code would remain the very same.
