Really? I couldn't find any Apple documentation that mentions this.
Also we have built powerpc code with the clang "LLVM compiler 1.5" and
it does run on powerpc.

Should we use the llvm-gcc compiler for the powerpc architecture instead?

clang in Xcode is compiled without powerpc support, it'll fall back to gcc.

That's right and it actually falls back to llvm-gcc.
I didn't know that.

Thanks!
