Detailed Description

This structure records a sequence of operations.

`ops' is the number of operations recorded. `cost' is their total cost. The operations are stored in `op' and the corresponding logarithms of the integer coefficients in `log'.

These are the operations: alg_zero total := 0; alg_m total := multiplicand; alg_shift total := total * coeff alg_add_t_m2 total := total + multiplicand * coeff; alg_sub_t_m2 total := total - multiplicand * coeff; alg_add_factor total := total * coeff + total; alg_sub_factor total := total * coeff - total; alg_add_t2_m total := total * coeff + multiplicand; alg_sub_t2_m total := total * coeff - multiplicand;

The first operand must be either alg_zero or alg_m.
