// 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 `!`.
