The first part of the change (removing the dead code) is fine.
However, I suggest to leave "must_align" in the code for now
because I have another patch in the queue that assigns a
calculated value to must_align. For that I'd have to revert this
part of your patch, so I think it's not worth the effort to remove
it in the first place. See
https://gcc.gnu.org/ml/gcc-patches/2016-05/msg00445.html

I've rebased my patch on yours and also removed EXTRA_ALIGN which
is also constant. I'll send new versions of both patches later.

Maybe it's better not to invent yet another solution to deal with
this and just do it like proposed in the patch. So if the default

So, the test expects an error:
/* { dg-error "arguments to .-mhotpatch=n,m. should be non-negative integers"
"" { target *-*-* } 1 } */
but no longer matches the error that really occurs?

THe attached patch fixes some dg-error tests that were broken
since the recent change of the error location.

(This is just meant to make it more feasible to be included in
Gcc6. If it's to late for this the code may be as well be used
for all targets.)

Subject: [PATCH] S/390: Fix warning
On S/390, __builtin_return_address and __builtin_frame_address
require the -mbackchain option to work for arbitrary stack frames.
The attached patch adds the option to two test cases to make them
work.
