            Bug ID: 88696
           Summary: Power VSX builtins missing vmuluwm / vector int
                    vec_mul (vector int, vector int);
           Product: gcc
           Version: 8.2.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: cand at gmx dot com
  Target Milestone: ---
            Target: ppc64le

Seems gcc is currently missing the VSX built-in that multiplies int vectors.
The vmuluwm instruction seems otherwise supported by gcc codegen.

vector int vec_mul (vector int, vector int);
vector unsigned int vec_mul (vector unsigned int, vector unsigned int);

It was added in ISA 2.07 aka POWER8. Apologies if the "target" component is not
the right place for this.
