Bug description:
= Validation =
For gcc-5, check that code generation is correct as per small C test case below.
== fpgatools ==
* compile autotest.c and strip chrpath
* change path in autotest_diff.sh from ./ to /usr/bin
* execute autotest and check error codes
== gambas3 ==
* execute gambas.test
== inisghttoolkit4 ==
$ apt install insighttoolkit4-python insighttoolkit4-examples
Run attached insightoolkit4.py script against an image file, e.g.
Circle.png from -examples package.
== libtsm ==
Nothing in the archive uses this... No idea why we have this package,
either release the update, or remove it from proposed.
== mariadb-10.0 ==
Run mariadb.sh
== percona-server-5.6 ==
Run percona.sh
== percona-xtrabackup ==
Execute $ xtrabackup --backup; xtracbackup --prepare; xtrabackup
--backup in a new directory

== Comment: #0 - Andreas Krebbel - 2016-04-19 05:22:12 ==
The following miscompilation was found in the Valgrind memcheck
preload library.
This compiler behavior can be reproduced with a small test case:
$ echo 'void foo (void) { volatile int a = 5; (void) a; }' | \
gcc -O2 -fno-omit-frame-pointer -o foo.o -c -x c - && objdump -d foo.o
foo.o: file format elf64-s390
Disassembly of section .text:
0000000000000000 <foo>:
0: b3 c1 00 2b ldgr %f2,%r11
4: b3 c1 00 0f ldgr %f0,%r15
8: e3 f0 ff 58 ff 71 lay %r15,-168(%r15)

A patch for upstream GCC has been posted on the mailing list. Backports will go into 4.9/5/6 branches after the upstream patch is applied.
https://gcc.gnu.org/ml/gcc-patches/2016-04/msg00910.html
This patch needs to be included in the Ubuntu 16.04 GCC 5 packages.
We have scanned the entire xenial universe repo for suspicious
sequences. Unfortunately several packages need to be rebuild after
including the patch. We recommend rebuilding at least the following
packages:
