--- Comment #4 from Martin Sebor <msebor at gcc dot gnu.org> ---
It looks to me like the failures might be due to bad assumptions in the test
about the precision of type short, and due to bad assumptions about the output
of %a made in the pass itself.  Let me look into fixing the former under this
bug but please go ahead and open a new bug for the %a failures.  They were
pointed out on the gcc-patches list
(https://gcc.gnu.org/ml/gcc-patches/2016-09/msg01684.html) but I don't think
there is a bug for them in Bugzilla yet.  Thanks for your help and patience!
