      3 ; It's not legal to fold a load from 32-bit stack slot into a 64-bit
      4 ; instruction. If done, the instruction does a 64-bit load and that's not
      5 ; safe. This can happen we a subreg_to_reg 0 has been coalesced. One
      6 ; exception is when the instruction that folds the load is a move, then we
      7 ; can simply turn it into a 32-bit load from the stack slot.
