Hi, Can you help to review this patch? Before [JDK-8353786](https://bugs.openjdk.org/browse/JDK-8353786), when a released jdk not supportting sleef (for any reason, e.g. low gcc version, intrinsic not supported, rvv not supported, and so on) runs on machine support vector operation (e.g. on riscv, it supports rvv), it can not call into sleef, but will not fail either, it falls back to java scalar version implementation. But after [JDK-8353786](https://bugs.openjdk.org/browse/JDK-8353786), it will cause an exception thrown at runtime.
This change the behaviour of existing jdk, and it should not throw exception anyway. @iwanowww @RealFYang Thanks! ------------- Commit messages: - initial commit Changes: https://git.openjdk.org/jdk/pull/24914/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=24914&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8355698 Stats: 4 lines in 1 file changed: 1 ins; 2 del; 1 mod Patch: https://git.openjdk.org/jdk/pull/24914.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/24914/head:pull/24914 PR: https://git.openjdk.org/jdk/pull/24914
