that the index needs a reload and find_reloads_address_1 will take care
of it.
If we decide to do something here, it must be that
`double_reg_address_ok' is true and that this address rtl was made by
eliminate_regs. We generate a reload of the fp/sp/ap + constant and
Handle all base registers here, not just fp/ap/sp, because on some
targets (namely Sparc) we can also get invalid addresses from preventive
subreg big-endian corrections made by find_reloads_toplev.
If we decide to do something, it must be that `double_reg_address_ok'
is true. We generate a reload of the base register + constant and
rework the sum so that the reload register will be added to the index.
This is safe because we know the address isn't shared.
We check for fp/ap/sp as both the first and second operand of the
innermost PLUS. */
