Hi Roland,

Thanks for spotting this.

This was an accidental change. I made it non verbose for my own debugging
purposes but forgot to revert it.

New webrev

 http://cr.openjdk.java.net/~enevill/8079565/webrev.01
<http://cr.openjdk.java.net/%7Eenevill/8079565/webrev.00/>

Only difference is reverting the changes to src/share/vm/opto/superword.cpp

There are now no changes to shared code, only _aarch64 files.

OK to push?
Ed.
