re PR rtl-optimization/37948 (IRA generates slower code)
2008-11-07 Vladimir Makarov <vmakarov@redhat.com>
PR rtl-optimizations/37948
* ira-int.h (struct ira_allocno_copy): New member constraint_p.
(ira_create_copy, ira_add_allocno_copy): New parameter.
* ira-conflicts.c (process_regs_for_copy): New parameter. Pass it
to ira_add_allocno_copy.
(process_reg_shuffles, add_insn_allocno_copies): Pass a new
parameter to process_regs_for_copy.
(propagate_copies): Pass a new parameter to ira_add_allocno_copy.
Fix typo in passing second allocno to ira_add_allocno_copy.
* ira-color.c (update_conflict_hard_regno_costs): Use head of
coalesced allocnos list.
(assign_hard_reg): Ditto. Check that assigned allocnos are not in
the graph.
(add_ira_allocno_to_bucket): Rename to add_allocno_to_bucket.
(add_ira_allocno_to_ordered_bucket): Rename to
add_allocno_to_ordered_bucket.
(push_ira_allocno_to_stack): Rename to push_allocno_to_stack. Use
head of coalesced allocnos list.
(push_allocnos_to_stack): Remove calculation of ALLOCNO_TEMP.
Check that it is aready calculated.
(push_ira_allocno_to_spill): Rename to push_ira_allocno_to_spill.
(setup_allocno_left_conflicts_num): Use head of coalesced allocnos
list.
(coalesce_allocnos): Do extended coalescing too.
* ira-emit.c (add_range_and_copies_from_move_list): Pass a new
parameter to ira_add_allocno_copy.
* ira-build.c (ira_create_copy, ira_add_allocno_copy): Add a new
parameter.
(print_copy): Print copy origination too.
* ira-costs.c (scan_one_insn): Use alloc_pref for load from
equivalent memory.
