Re: use of preserve_temp_slots in copy_blkmode_from_reg

[Richard Kenner]

    While looking at this, I found that expr.c always calls
    free_temp_slots immediately followed by pops_temp_slots. Isn't the
    call to free_temp_slots pointless there?

It looks like it is now.  It didn't used to be though (when we had RTL_EXPR).
