| // Issue #34427: On ARM, the code in `foo` at one time was generating | |
| // a machine code instruction of the form: `str r0, [r0, rN]!` (for | |
| // some N), which is not legal because the source register and base | |
| // register cannot be identical in the preindexed form signalled by | |
| // the `!`. | |
