1004 Don't reload directly from oldequiv; if it's a pseudo with a
1005 stack slot, use reload_in[j].
1006 Check that reload_in_reg[j] is a MEM before replacing reload_in
1007 from reg_reloaded_contents.
1008 Include non-spill registers in reload inheritance processing.
1009 Also try to use reload_out_reg to set spill_reg_store /

1012 there is a single set.

1014 Add code to allow deletion of output reloads that use no spill reg.
1015 At the end, set reload_override_in to oldequiv.

1021 actual store isn't found.
1022 When looking for a store of a value not loaded in order to call
1023 delete_output_reload, count_occurences should return 0 for no
1024 loads; but discount inherited input reloadill_reg_stored_to.
1025 Do checks for extra uses of REG. Changed all

1035 (reload_reg_free_for_value_p): handle RELOAD_FOR_OPERAND_ADDRESS /

1039 (count_occurrences): Use rtx_equal_p for MEMs.
1040 (inc_for_reload): Return instruction that stores into RELOADREG.
1041 New argument two, IN, and rtx. Changed all callers.
1042 (calculate_needs_all_insns, reload_as_needed):
1043 Don't clear after_call for a CLOBBER.
1044 Keep track of how many hard registers need to be copied from
1045 after_call, and don't clear after_call before we have seen
1046 that much copies, or we see a different instruction.
