25/* This file is supposed to be used for 604, 604e, 744x/745x/747x (G4+), i.e.,
26   32-bit PowerPC processors with reasonably fast integer multiply insns.  The
27   values below are chosen to be best for the latter processors, since 604 is
28   largely irrelevant today.
29
30   In mpn/powerpc32/750/gmp-mparam.h there are values for 75x (G3) and for
31   7400/7410 (G4), both which have much slower multiply instructions.  */
