Hi, Bug: https://bugs.openjdk.java.net/browse/JDK-8237521 Webrev: http://cr.openjdk.java.net/~ngasson/8237521/webrev.01/
This is a follow-up to JDK-8236634 which just contained changes to the tests to make them build/pass on 32-bit systems for JDK 14. This patch removes the test workarounds and fixes two things to make them pass:
* In Unsafe_AllocateMemory0 handle the case where the aligned-up size overflows a 32-bit size_t and throw an OutOfMemoryError instead of calling os::malloc(0).
* Change the value of Utils.MAX_ALIGN from 16 to 8 on 32-bit systems, as malloc can return addresses that are only 8-byte aligned.
Tested jdk_foreign on x86_32, arm32, aarch64, x86_64. Thanks, Nick
