        * explow.c (convert_memory_address_addr_space_1): Formatting fix.

        PR debug/70628
        * rtl.h (convert_memory_address_addr_space_1): New prototype.
        * explow.c (convert_memory_address_addr_space_1): No longer static,
        add NO_EMIT argument and don't call convert_modes if true, pass
        it down recursively, remove break after return.
        (convert_memory_address_addr_space): Adjust caller.
        * simplify-rtx.c (simplify_unary_operation_1): Call
        convert_memory_address_addr_space_1 instead of convert_memory_address,
        if it returns NULL, don't simplify.

        * gcc.dg/torture/pr70628.c: New test.
