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. */ 32 33/* 1417 MHz PPC 7447A */ 34 35#define DIVREM_1_NORM_THRESHOLD 0 /* always */ 36#define DIVREM_1_UNNORM_THRESHOLD 0 /* always
