Ramana commented in the submission email:

    I noticed that for T32 we don't allow any old register for DImode
    values. The restriction of an even register is true only for ARM state
    because the ISA doesn't allow any old register in this place. In a few
    large .i files that I had knocking about, noticed a nice drop in stack
    usage and a generally improved register allocation strategy.
