The speed of mpn_addmul_1 is 9.75 c/l; 28mpn_addmul_2 could run at 8 c/l. mpn_addmul_N could 29approach 6 c/l, but register shortage will make this hard. 30 31Perhaps nails is the way to go even for an embedded processor like 32this, since the umlal accumulation could be used very effectively in 33that case. with just 2 nail bits, we should get close to 5 c/l for a 34mpn_addmul_N or mpn_mul_basecase. 35
