Actually, the thing that makes Sparc64 different from Alpha and MIPS64
is the presence of a true 32-bit compare. Because of that, I would
expect far far fewer sign extensions to be needed for your average
SImode variable.
Yes, I agree, that will make a *big* difference. However, there's also
HImode and QImode to consider.
