/* This file is supposed to be used for 604, 604e, 744x/745x/747x (G4+), i.e.,
32-bit PowerPC processors with reasonably fast integer multiply insns. The
values below are chosen to be best for the latter processors, since 604 is
largely irrelevant today.
In mpn/powerpc32/750/gmp-mparam.h there are values for 75x (G3) and for
7400/7410 (G4), both which have much slower multiply instructions. */
