[Bug 2095441] Re: S390x build of openjdk crashes with the segmentation fault
To summarize this: Using the openjdk-25 upstream default, that is "-march=10", the build works fine, as well as the succeeding tests. However, the general defaults that we use in Ubuntu (as of today) are -arch=z13 and mtune=z15. Means this requires us to manually override the baseline, which can be done. But since z10 is pretty outdated (it's from 2008 !), this override should not be permanently, and we want to ask IBM to help bringing upstream to a more modern baseline (like for example z13). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2095441 Title: S390x build of openjdk crashes with the segmentation fault To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-z-systems/+bug/2095441/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
