Please help us by testing this new package.  See

to enable and use -proposed.Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested and change the tag from
verification-needed-artful to verification-done-artful. If it does not
fix the bug for you, please add a comment stating that, and change the
tag to verification-failed-artful. In either case, without details of
your testing we will not be able to proceed.

Title:
  add support for thunderx2 cores

Status in gcc-5 package in Ubuntu:
  Fix Released
Status in gcc-5 source package in Xenial:
  Fix Committed
Status in gcc-5 source package in Zesty:
  Won't Fix
Status in gcc-5 source package in Artful:

Status in gcc-5 source package in Bionic:
  Fix Released

Bug description:
  [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.

  [Test Case]
  gcc-5 hello.c -o hello -mcpu=thunderx2t99
  hello.c:1:0: error: unknown value ‘thunderx2t99’ for -mcpu
   #include <stdio.h>
   ^

  [Regression Risk]
  The patchset includes a rename of the "vulcan" core to "thunderx2t99". It retains backwards compatibility with the "vulcan" name to avoid regressing users that may already be using that name.
