re PR rtl-optimization/50107 ([IRA, i386] allocates registers in very non-optimal way)
2011-08-17 Vladimir Makarov <vmakarov@redhat.com>
PR rtl-optimization/50107
* ira-int.h (ira_hard_reg_not_in_set_p): Remove.
(ira_hard_reg_in_set_p): New.
* ira-color.c (calculate_saved_nregs): New.
(assign_hard_reg): Use it. Set up allocated_hard_reg_p for all
hard regs.
(allocno_reload_assign, fast_allocation): Use
ira_hard_reg_set_intersection_p instead of
ira_hard_reg_not_in_set_p.
* ira.c (setup_reg_renumber): Use
ira_hard_reg_set_intersection_p instead of
ira_hard_reg_not_in_set_p.
(setup_allocno_assignment_flags, calculate_allocation_cost): Use
ira_hard_reg_in_set_p instead of ira_hard_reg_not_in_set_p.
* ira-costs.c (ira_tune_allocno_costs): Use
ira_hard_reg_set_intersection_p instead of
ira_hard_reg_not_in_set_p.
