[8u] Request for enhancement backport approval for 8170328: PPC64: Use andis instead of lis/and

[Gustavo Romero]

Hi,

Could the following enhancement backport be approved, please?

Bug		: https://bugs.openjdk.java.net/browse/JDK-8170328
Review		: http://mail.openjdk.java.net/pipermail/hotspot-compiler-dev/2016-November/024997.html
Changeset	: http://hg.openjdk.java.net/jdk9/jdk9/hotspot/rev/3866c59ee901

Some Neo4j workloads (like LDBC benchmark) can get a benefit from that change.
This is a significant ppc64-only performance improvement which improves JITed
code and it applies cleanly. It's low risk and does not affect any of the Oracle
platforms in any way. The proposed integration date is as soon as granted since
there is no remaining work to be done.

Thank you.


Best regards,
Gustavo
