bpo-46504: faster code for trial quotient in x_divrem() by tim-one · Pull Request #30856 · python/cpython (original) (raw)
This brings x_divrem() back into synch with x_divrem1(), which was changed
in bpo-46406 to generate faster code to find machine-word division
quotients and remainders. Modern processors compute both with a single
machine instruction, but convincing C to exploit that requires writing
less "clever" C code.
