| 25 # The "ld" at Fetch32 is potentially faulting instruction. | |
| 26 # If the instruction traps the trap handler will arrange | |
| 27 # for control to resume at Fetch32Resume. | |
| 28 # By convention with the trap handler we ensure there is a non-CTI | |
| 29 # instruction in the trap shadow. | |
