I tried rebuilding on AArch64 and immediately encountered a problem with
the AArch64 ad file. This appears to be caused by:
8068977: Remove unused sun.misc.Unsafe prefetch intrinsic support
which (amongst other things) removed PrefetchRead/Write nodes. However
AArch64 still includes a rule for PrefetchRead/Write.
I'm still looking at how to fix both this problem and whatever else may
be broken once it is fixed (no doubt there /will be/ other breakages).
Previously when pulling upstream changes down into the aarch64-port repo
we had to trawl through the change sets identifying and reapplying
x86_64-specific updates to the AArch64 tree. The same action will be
required with this merge upstream. I don't suppose this requires us to
delay the merge if x86 builds and passes all tests -- Andrew Haley may
have more to say on that front.
