Detailed Description
The entry for our multiplication cache/hash table.
Field Documentation
| enum alg_code alg_hash_entry::alg |
The best multiplication algorithm for t.
| struct mult_cost alg_hash_entry::cost |
The cost of multiplication if ALG_CODE is not alg_impossible. Otherwise, the cost within which multiplication by T is impossible.
