Hi, We have discovered issues with gcc 7.3 on zLinux, combined with OpenJDK's default compiler options has highlighted a couple of native code issues, with undefined behaviours:
- validating loop test array bounds
- left shifts of negative values I have created bug https://bugs.openjdk.java.net/browse/JDK-8209786 and attached the webrev fix here: http://cr.openjdk.java.net/~aleonard/8209786/webrev.00/
This has already been discussed and refined on the "s390x-port-dev" maillist and as it was pointed out, it should have been posted here...
I'd like to request a sponsor for this fix please?
Many thanks Andrew
