[Bug 1727540] Re: add support for thunderx2 cores
** Description changed: [Impact] gcc-5 doesn't know about thunderx2 cores, so optimization flags for this target will fail. While it is possible to generate the same code by referencing the previous name of the core (vulcan), that is non-obvious to the end user.

I think the test case should also include "-mcpu=vulcan" with the new version to ensure that the backwards compatibility does in fact still work. ** Changed in: gcc-5 (Ubuntu Zesty) Status: New => Won't Fix ** Changed in: gcc-5 (Ubuntu Artful) Status: In Progress => Fix Committed ** Tags added: verification-needed verification-needed-artful -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1727540 Title: add support for thunderx2 cores To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gcc-5/+bug/1727540/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
