   1 # REQUIRES: aarch64
   2
   3 ## Old versions of Android (Android 11 & 12) have very strict parsing logic on
   4 ## the layout of the ELF note. This test ensures that backwards compatibility is
   5 ## maintained, i.e. new versions of the linker will still produce binaries that
   6 ## can be run on these versions of Android.
