This is a fairly huge backport from Shenandoah's dev line (then jdk9) to shenandoah/jdk8u and from there to aarch64-port/jdk8u-shenandoah. It brings:
- bunch of new features (e.g. a separate update-refs phase, parallel and concurrent code cache scanning, etc)
- much improved performance (both macro- and micro-performance)
- much improved stability (we did test this fairly extensively, and added many regression tests)
- much improved usability (e.g. better option handling, much more useful output)
- many bugfixes and tests and code improvements
- lesser diff compared to upstream
All of this has baked considerably in shenandoah/jdk8u for a while, gone through testing and testing and testing (also, testing by interested early adopters) and fixing. I simply transplanted all relevant changesets from shenandoah/jdk8u to aarch64-port/jdk8u-shenandoah with no fuzz or any problems.
It's then been tested again by running the hotspot_gc_shenandoah jtreg test group (i.e. the whole Shenandoah jtreg test suite), again without issues.
A list of all changesets can be found here:

Ok to push?
The update breaks building without precompiled headers. See attached patch. Thanks, -- Andrew :) Senior Free Java Software Engineer Red Hat, Inc.
