_flint_mpn_poly_mulmid_cutoff, _flint_mpn_poly_karatsuba_cutoff
Synopsis
#include <flint/mpn_extras.h>The Karatsuba cutoff (shorter length) used by _flint_mpn_poly_mulmid for coefficients of n_1 and n_2 limbs. _flint_mpn_poly_karatsuba_cutoff is the tuned value, from 32 for one-limb products down to 4 for large coefficients (64 down to 8 for squaring); _flint_mpn_poly_mulmid_cutoff returns it unless overridden with the global _flint_mpn_poly_mulmid_force_cutoff.
