I don't understand what this patch is for. Surely it cannot be needed to
make AArch64 builds work?

It looks like this is intended to re-enable building of code on x86
using the AArch64 simulator (i.e. run make x86 with BUILTIN_SIM=true).
If so then

  i) I am not sure whether we really want to maintian support for
simulator builds on jdk9(+)

  ii) I would be very surprised to find that this is the only thing that
needs fixing to make the simulator build fully functional again (we lost
all the extra shared code changes which were needed to support proper
debugging in the upstream merge).

Could you please explain the provenance, purpose and value of this patch?

regards,
