// 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 `!`.
|
|
//
|
|
// See LLVM bug: https://llvm.org/bugs/show_bug.cgi?id=28809
