C NOTES
C * It is possible to keep the carry chain alive between the addition blocks
C and thus avoid csinc, but only for addmul_1. Since that saves no time
C on the tested pipelines, we keep addmul_1 and submul_1 similar.
C * We could separate feed-in into 4 blocks, one for each residue (mod 4).
C That is likely to save a few cycles.
