Hi,

http://cr.openjdk.java.net/~enevill/8130687/webrev/hotspot.changeset adds support for crc32c on aarch64. This has previously been added for Sparc (see https://bugs.openjdk.java.net/browse/JDK-8073583) Performance measurements shows the throughput goes from ~620MB/s to 2938 MB/s == approx 4.7x performance improvement. Tested before and after with jtreg hotspot. In both cases Test results: passed: 867; failed: 3; error: 7 Please review. Thanks, Ed.
