In case I haven't mentioned already, in the OSX ABI there is a small register
preservation difference between 32-bit and 64-bit PowerPC:

In section 'Register Preservation', for ppc64 GPR13 is marked "Reserved for
thread-specific storage."

http://developer.apple.com/documentation/DeveloperTools/Conceptual/LowLevelABI/Articles/32bitPowerPC.html#//apple_ref/doc/uid/TP40002438-SW18

http://developer.apple.com/documentation/DeveloperTools/Conceptual/LowLevelABI/Articles/64bitPowerPC.html#//apple_ref/doc/uid/TP40002471-SW11

Does this require any special handling? If I understood the code correctly,
r13..r31 are being 'preserved' by the stmw/lmw I had to replace with multiple
std/ld.
