A load from a global variable should certainly be seen before reload, unless your insn patterns permit addition, or whatever, using a memory address. It's true in any case that you will sometimes see these loads during reload, and you will have to cope with that. However, that should not be the common case--it should only happen when a register is spilled. Ian
