Hi, Can you help to review the patch? Previously it's https://github.com/openjdk/jdk/pull/18605. This pr is based on https://github.com/openjdk/jdk/pull/20781.
Thanks! ## Test ### tests: * test/jdk/jdk/incubator/vector/ * test/hotspot/jtreg/compiler/vectorapi/ ### options: * -XX:UseSVE=1 -XX:+EnableVectorSupport -XX:+UseVectorStubs * -XX:UseSVE=0 -XX:+EnableVectorSupport -XX:+UseVectorStubs * -XX:+EnableVectorSupport -XX:-UseVectorStubs ## Performance ### Tests jmh tests are test/micro/org/openjdk/bench/jdk/incubator/vector/operation/ from vectorIntrinsics branch in panama-vector. It's good to have these tests in jdk main stream, I will do it in a separate pr later. (These tests are auto-generated tests from some script&template, it's good to also have those scrip&template in jdk main stream, but those scrip&template generates more other tests than what we need here, so better to add these tests in another pr). ### Options * +intrinsic: 'FORK=1;ITER=10;WARMUP_ITER=10;JAVA_OPTIONS=-XX:+UnlockExperimentalVMOptions -XX:+EnableVectorSupport -XX:+UseVectorStubs' * -intrinsic: 'FORK=1;ITER=10;WARMUP_ITER=10;JAVA_OPTIONS=-XX:+UnlockExperimentalVMOptions -XX:+EnableVectorSupport -XX:-UseVectorStubs' ### Performance data I have re-tested, there is no much difference from https://github.com/openjdk/jdk/pull/18605, so please check performance data in that pr. ------------- Commit messages: - Initial commit Changes: https://git.openjdk.org/jdk/pull/21502/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=21502&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8312425 Stats: 161 lines in 6 files changed: 156 ins; 1 del; 4 mod Patch: https://git.openjdk.org/jdk/pull/21502.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/21502/head:pull/21502 PR: https://git.openjdk.org/jdk/pull/21502
