# REQUIRES: aarch64

## Old versions of Android (Android 11 & 12) have very strict parsing logic on
## the layout of the ELF note. This test ensures that backwards compatibility is
## maintained, i.e. new versions of the linker will still produce binaries that
## can be run on these versions of Android.
