Need to use `jlong_to_ptr` instead of raw cast. I've also fixed another latent issue in `CLayouts` where we were initializing `C_LONG_LONG` with the `long` layout. This was resulting in a class cast exception when running the XorTest benchmark. The size of `long` on Linux x86 32-bits is 4 bytes, so the returned layout has type `ValueLayout.OfInt` which we then try to cast to `ValueLayout.OfLong`, resulting in a CCE. This would also be an issue on Windows.
Testing: running XorTest benchmark on linux-x86 and windows-x64. ------------- Commit messages: - Fix x86 running of XorTest Changes: https://git.openjdk.org/jdk/pull/16913/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=16913&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8321130 Stats: 5 lines in 2 files changed: 2 ins; 0 del; 3 mod Patch: https://git.openjdk.org/jdk/pull/16913.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/16913/head:pull/16913 PR: https://git.openjdk.org/jdk/pull/16913
