Description
General primitive array equality/comparison/mismatch was intrinsified on x86 via JDK-8143355. A _vectorizedMismatch stub routine was added that is wired up in C2. The same stub routine can also be wired up in C1. For an example of how to wire up a stub routine in the interpreter and C1 see the fix for x86 CRC32 intrinsics: https://bugs.openjdk.java.net/browse/JDK-7088419 http://hg.openjdk.java.net/hsx/hsx25/hotspot/rev/b800986664f4
