RFR: 8169697: aarch64: vectorized MLA instruction not generated for some test cases
by Ningsheng Jian 04 May '17

04 May '17

Hi, NEON vector MLA instructions can not be generated in some simple multiply-add cases. Bug: https://bugs.openjdk.java.net/browse/JDK-8169697 The following webrev contributed by Yang Zhang (yang.zhang(a)linaro.org) can resolve it. Webrev: http://cr.openjdk.java.net/~njian/8169697/webrev.00/ Please help to review it. To minimize impact, this patch only changes aarch64 specified code. Do you think this is OK for 9? If yes, do we need a FC Extension Request? In the mean time, Yang also has a more generic fix for this issue, which patches share code and could also fix this issue: http://cr.openjdk.java.net/~njian/8169697/webrev.share/ Which do you think is better? Both patches tested with fastdebug jtreg. Thanks, Ningsheng

RFR: 8168503 JEP 297: Unified arm32/arm64 Port
by Bob Vandette 24 Mar '17

24 Mar '17

Please review the proposed changes to be integrated under JEP 297. Summary: This JEP adds arm32 and arm64 Linux platform support to OpenJDK for JDK 9. This changeset also removes the support for the pregenerated interpreter since this is no longer supported. The addition of arm64 does not replace the existing aarch64 port. A new configure option (-with-cpu-port=) allows for the selection of the existing aarch64 versus the 64-bit arm64 support being added via this JEP. Please refer to the JEP for more details. JEP 297: https://bugs.openjdk.java.net/browse/JDK-8168503 Webrev: http://cr.openjdk.java.net/~bobv/8168503 Note: A complete build-able forest containing these changes is located here: http://hg.openjdk.java.net/aarch32-port/jdk9-arm3264 Thanks, Bob Vandette
