In-Reply-To: Message from Geert Uytterhoeven <Geert.Uytterhoeven@cs.kuleuven.ac.be> of "Tue, 20 Apr 1999 13:39:39 +0200." <Pine.LNX.4.10.9904201339320.26859-100000@mercator.cs.kuleuven.ac.be>
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.
