- Subject: PPC AltiVec request: add an abi variant
To facilitate using AltiVec in the NetBSD kernel, I'd really like
a environment where all AltiVec registers were considered to be
callee-saved. If that happened, the kernel wouldn't have to incur
the overhead of saving/restoring AltiVec state in the kernel other
than where it's used.
It doesn't seem that it would be to difficult to implement this.
Maybe call this abi=kaltivec or ???
