--- Comment #2 from Robin Dapp <rdapp at gcc dot gnu.org> ---
At first glance it doesn't really look like a target issue.

Tried it on x86 and it fails as well with
-O3 -march=3Dnative pr114396.c -fno-vect-cost-model -fwrapv

short a =3D 0xF;
short b[16];

int main() {
        for (int e =3D 0; e < 9; e +=3D 1)
                b[e] =3D a *=3D 0x5;

        if (a !=3D 2283)
                __builtin_abort ();
