I have tried compiling qemu with xlc and it chokes on the asm. I 
believe that it uses a different syntax than gcc for this. I don't 
know what its syntax is, but if anybody does it shouldn't be too hard 
to make a patch which lets it compile.

Using xlc does seem to give substantially better performance than 
gcc, and not just on floating point code.

Cheers,
Josh.
