I'd really like to see hard statistics about this. If I recall correctly,
Ulrich Drepper did some experiments with using -mregparm for internal
calls inside glibc and found it made no difference, or in some cases made
things worse. There are enough "intuitively" correct optimisations that
slow things down out there already ...
