--- Comment #14 from bin cheng <amker at gcc dot gnu.org> --- Author: amker Date: Wed May 8 11:37:45 2019 New Revision: 271008 URL: https://gcc.gnu.org/viewcvs?rev=271008&root=gcc&view=rev Log: PR tree-optimization/90078 * tree-ssa-loop-ivopts.c (INFTY): Increase value for infinite cost. (struct comp_cost): Promote type of members to int64_t. (infinite_cost): Don't set complexity in initialization. (comp_cost::operator +,-,+=,-+,/=,*=): Assert when cost computation overflows to infinite_cost. (adjust_setup_cost): Promote type of parameter and cost computation to int64_t. (struct ainc_cost_data, struct iv_ca): Promote type of member to int64_t. (get_scaled_computation_cost_at, determine_iv_cost): Promote type of cost computation to int64_t. (determine_group_iv_costs, iv_ca_dump, find_optimal_iv_set): Use int64_t's format specifier in dump. gcc/testsuite * g++.dg/tree-ssa/pr90078.C: New test. Added: trunk/gcc/testsuite/g++.dg/tree-ssa/pr90078.C Modified: trunk/gcc/ChangeLog trunk/gcc/testsuite/ChangeLog trunk/gcc/tree-ssa-loop-ivopts.c
