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.

enum machine_mode alg_hash_entry::mode

     The mode in which we are multiplying something by T.  

bool alg_hash_entry::speed

     Optimized for speed? 

Referenced by sdiv_cost().

unsigned HOST_WIDE_INT alg_hash_entry::t

     The number we are multiplying by.
