Lu <[EMAIL PROTECTED]> Backport from mainline: 2008-11-10 Vladimir Makarov <[EMAIL PROTECTED]> 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.
