Hmm, I think this means that the asm code uses more registers than gcc
can offer it. Apparently the ABI on MacOS has fewer registers
available for various purposes then the one on Linux? The asm code
currently asks for 8 registers. It might be possible to get rid of one
of them.
A temporary fix could be changing this:
#if defined (__i386__) || defined (__amd64__)
to this:
#if !defined(__APPLE__) && (defined (__i386__) || defined (__amd64__))
twice in that file.
