reg_equiv_memory_loc[regno] and num_not_at_initial_offset
are both nonzero.
Include *recog_operand_loc in commutativity operand changes.
Generate optional output reloads.
Delete reference to n_memlocs. Don't set *recog_operand_loc before
processing operands. Call make_memloc in reg_equiv_address code.
Set *recog_operand_loc only after processing operands, and only
if replace is true. Return a value.
When changing address reload types for operands that didn't get
reloaded, use RELOAD_FOR_OPADDR_ADDRESS for
RELOAD_FOR_INPADDR_ADDRESS / RELOAD_FOR_OUTADDR_ADDRESS reloads.
Don't emit USEs for pseudo SUBREGs when not replacing.
(find_reloads_address): Do make_memloc substitution also when

find_reloads.
Call forget_old_reloads_1 with contents of reloaded auto_inc
expressions if the actual addressing can't be changed to match the
auto_inc.
(choose_reload_regs): For inheritance, replace
reload_reg_free_before_p test with reload_reg_ions.
(emit_reload_insns): If reload_in is a MEM, set OLD to
reload_in_reg[j].
Don't reload directly from oldequiv; if it's a pseudo with a
stack slot, use reload_in[j].
Check that reload_in_reg[j] is a MEM before replacing reload_in
from reg_reloaded_contents.
Include non-spill registers in reload inheritance processing.
Also try to use reload_out_reg to set spill_reg_store /
reg_last_reload_reg.
In code to set new_spill_reg_store, use single_set to find out if
there is a single set.
Add code that allows to delete optional output reloads.
Add code to allow deletion of output reloads that use no spill reg.
At the end, set reload_override_in to oldequiv.
Also call delete_output_reload if reload_out_reg is equal to old
in oldequiv code.
Add code to call delete_output_reload for stores with no matching load.
Set / use spill_reg_stored_to.
Handle case where secondary output reload uses a temporary, but
actual store isn't found.
When looking for a store of a value not loaded in order to call
delete_output_reload, count_occurences should return 0 for no
loads; but discount inherited input reloadill_reg_stored_to.
Do checks for extra uses of REG. Changed all
callers.
Use delete_address_reloads.
(reload): Take return value of find_reloads into account.
If a no-op set needs more than one reload, delete it.

can ignore RELOAD_FOR_INPUT_ADDRESS / RELOAD_FOR_INPADDR_ADDRESS

register in use.
(reload_reg_free_for_value_p): handle RELOAD_FOR_OPERAND_ADDRESS /
RELOAD_FOR_OPADDR_ADDR.
Take into account when an address address reload is only needed
for the address reload we are considering.

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