--- Comment #1 from Peter Bergner <bergner at gcc dot gnu.org> ---
Using recent mainline and gcc10 builds (ie, gcc versions with MMA support),=
 I
don't see the ICE anymore:

bergner@pike:~/gcc/BUGS/PR96178$ gcc -S -mvsx pr96178.i=20
pr96178.i: In function =E2=80=98foo2=E2=80=99:

pr96178.i:8:3: error: invalid use of MMA operand of type =E2=80=98__vector_=
