- This directory contains mpn functions for ARM processors.
- It has been optimized for StrongARM.
- TODO
- Write mpn_addmul_2. The speed of mpn_addmul_1 is 9.75 c/l;
- mpn_addmul_2 could run at 8 c/l. mpn_addmul_N could
- approach 6 c/l, but register shortage will make this hard.
- Perhaps nails is the way to go even for an embedded processor like
- this, since the umlal accumulation could be used very effectively in
- that case. with just 2 nail bits, we should get close to 5 c/l for a
- mpn_addmul_N or mpn_mul_basecase.
