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