As far as I can tell it is exposed already to the middle-end via that

Hi,
Why can't we replace function force_expr_to_var_cost directly with function
computation_cost in tree-ssa-loop-ivopt.c?
Actually I think it is inaccurate for the current recursive algorithm in
force_expr_to_var_cost to estimate expr cost. Instead computation_cost can
count some back-end factor
