gcc-5 affected in xenial and bionic.
gcc-6 affected in bionic only.
gcc-7 and gcc-8 affected, and currently have inflight SRU updates to
v7.5 and v8.3 in bionic, thus are not going to be updated at the moment
anywhere I don't think.
gcc-9 is fixed in focal.

Bug description:
Miscompilation in autovectorized code.
---Steps to Reproduce---
See GCC BZ: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=92950
The following testcase abort when being compiled with -O3 -march=z13
on IBM Z:
struct a {
int b;
char c;
};
struct a d = {1, 16};
struct a *e = &d;
int f = 0;
int main() {
struct a g = {0, 0 };
f = 0;
for (; f <= 1; f++) {
g = d;
*e = g;
}
if (d.c != 16)
__builtin_abort();
}
The movv1qi pattern emits halfword load instructions instead of character
loads.
All GCC versions since GCC 5 are affected.
Patches for GCC 8, 9, and 10 have been committed to the gcc.gnu.org branches.
Userspace tool common name: gcc
The userspace tool has the following bit modes: 64
Userspace rpm: various Ubuntu gcc packages
Package need to updated within LP
