Dear Vladimir and all:
Can I please request reviews for the following change?
As Volker's comments in the above JIRA, this is a ppc64-only improvement
which will not
affect any of the Oracle platforms in any way.
This change includes new implementation of CRC32 Intrinsics for ppc64le.
In my local experiment, CRC32 of 64KB was calculated more than 20 times
faster than original.
Performance of CRC32 Intrinsic is important to run recent Apache
A Cassandra daemon needs to read 64KB data from a disk with CRC32 checksum
This JIRA entry has "jdk9-fc-request" label.
If there is a chance to include new change in JDK 9 for ppc64le, I would
like to request
a review for this change.
