Can you elaborate? We are talking about the mode returned from
addr_for_mem_ref here. I do now understand how this can be anything
but an address mode:
If you look at the users of addr_for_mem_ref, they all look someting
like this:
op0 = addr_for_mem_ref (&addr, as, true);
op0 = memory_address_addr_space (mode, op0, as);
mem = gen_rtx_MEM (mode, op0);
So the result is used as address argument to create a MEM. This must
certainly be address mode (Pmode) then -- that's basically the definition
of address mode (the mode of the address argument to MEM).
