  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.  */
