I know very little about the C++ ABI so this may be C++ specific. I
thought r8 was meant to be a return register and not an input
register and that it's valid to clobber it in any function call,
whether the function returns a value or void?
I am sitting at home right now and all my documents are in the office
so I can't look it up.
