/* The PowerPC ABI specifies aggregates that are not returned by value
are returned in a storage buffer provided by the caller. The
address of the storage buffer is provided as a hidden first input
arguement in register r3. The PowerPC ABI does not guarantee that
argument in register r3. The PowerPC ABI does not guarantee that
register r3 will not be changed while executing the function. Hence, it
cannot be assumed that r3 will still contain the address of the storage
buffer when execution reaches the end of the function.
