Bug Description
[Impact]
valgrind fails w/ s390x binaries that include the popcnt instruction.
[Test Case]
sudo apt build-dep valgrind
apt source valgrind
cd valgrind-*
fakeroot make -f debian/rules build
make -C ./none/tests/s390x/ popcnt
perl tests/vg_regtest none/tests/
if [ $? -eq 0 ]; then
echo "PASS"
else
echo "FAIL"
fi
[Regression Risk]
Fix is localized to s390x. It is an upstream cherry-pick, so regression risk should be mitigated by upstream support.
