Ok, I think I'll stick to using a separate pointer for qh then. Storing qh early may also have the advantage of allowing more tail calls. I'm about to push the first step, with C implementations of mpn_div_qr_1 and mpn_div_qr_1n_pi1. The C code implements two variants of mpn_div_qr_1n_pi1: First is a plain loop around udiv_qrnnd_preinv, second uses the new method. We'd need support in tuneup to select the best variant. And also support for tuning the DIV_QR_1_ thresholds. I wrote: > In principle, since these are internal functions, I was a bit confused here. mpn_div_qr_1 is intended as a public function.
