Re: Reload inheritance and auto inc/dec


    Ok, but since the pseudo only exists during a short interval, and
    reg:SI doesn't change in that interval, any occurrence of the pseudo
    can be safely replaced by the REG_EQUIV rtx.  Wouldn't this be a valid
    use of REG_EQUIV?

Well, "sort of".  The problem is how can you ensure that subsequent code
transformation might make that other register change during that interval.
