CR for RFR 8142980

[Berg, Michael C]

Yes to all with no issues.
We even extended compiler tests for 64bit and 32bit to cover AVX{0,1,2} as well as SpecJVM2008 on AVX {0..3}

Regards,
Michael

Looks good to me. Have you tested it with all the jtreg tests available in the jdk repo (jdk/test, hospot/test)?

Hi Folks,

I would like to contribute bug fixes for AVX 512 which address 64-bit derby on EVEX enabled targets as well as KNL support and instrinsic support for AVX512.
These changes are also needed for a follow on changeset which introduces the use of these additions in the AVX512 instrinsic code.

Bug-id: https://bugs.openjdk.java.net/browse/JDK-8142980

webrev:

The derby metric fails to run on 64-bit SKX and KNL EVEX enabled platforms. Also code support is needed for AVX512 intrinsics and include KNL support.

Thanks,
Michael
