altivec

Some questions about altivec & LinuxPPC:

1. is there a free C compiler supporting altivec instructions for
   linuxPPC?

2. would it be possible to trap altivec instructions on a non-altivec
   processor and reroute them through code using generic instructions?
   (I believe this is how Apple's MacOS altivec simulator does it).
   Presumably there is a bad instruction interrupt or something and
   code in the kernel to trap these interrupts? (Excuse my naivety;
   I'm more of a kernel user than hacker - for now!)

3. has anyone written a C library to simulate the altivec instructions?
