Synopsis
#include <flint/mpn_extras.h>void flint_mpn_fmmamod_preinvn(mp_ptr r, mp_srcptr a, mp_srcptr b, mp_srcptr e, mp_srcptr f, mp_size_t n, mp_srcptr d, mp_srcptr dinv, ulong norm)sourcevoid flint_mpn_fmmamod_preinvn_2(mp_ptr r, mp_srcptr a, mp_srcptr b, mp_srcptr e, mp_srcptr f, mp_srcptr d, mp_srcptr dinv, ulong norm)sourceSet (r, n) to ab + ef \bmod d with a single reduction, given d holding d 2^{\mathrm{norm}} and its inverse dinv; the operands and the result are unshifted. The second version is for n = 2.
