	The original POWER architecture with the MQ register allowed a
short sequence to provide this 64-bit functionality.  The PowerPC
instruction set does not provide the necessary building blocks, so GCC
falls back to the C implementation in libgcc2.c producing the assembly
code shown in the later posting.
