I cloned and patched the graal-core/graal tree and then copied it into
my hotspot space as follows

  $ cp /path/to/graal-core/graal \
     /otherpath/to/hs/hotspot/src/share/classes/jdk.vm.compiler

With this and the extra tweaks to compiledCI_aarch64.cpp mentioned in
the previous reply I managed to build a slowdebug release which
successfully ran 'java Hello' and 'javac Hello.java'.

Andrew Haley is currently trying to get Graal itself to run on AArch64.
So, this is probably good enough for now to confirm the acceptability of
the hs and jaotc change sets.
