I was wondering whether the implementation of qemu is tied to gcc or if it might be interesting to try to compile using IBM's compiler, which is able to generate

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.
