            Bug ID: 82465
           Summary: vec_sqrt() for vector double erroneously fails for z13
           Product: gcc
           Version: 8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: markos at freevec dot org
  Target Milestone: ---
              Host: s390x-ibm-linux-gnu
            Target: s390x-ibm-linux-gnu
             Build: s390x-ibm-linux-gnu

The following code:

#include <vecintrin.h>

int main() {
        __vector double v = { 2.0,  1.0 };

        __vector double prod = vec_sqrt(v);
}

works for z14 as expected, but fails on z13:

$ g++ -march=z13 -mzvector zvectortest2.cpp -o zvectortest2
zvectortest2.cpp: In function 'int main()':
zvectortest2.cpp:6:35: error: '__vector(4) int
__builtin_s390_vec_sqrt(__vector(4) int)' requires z14 or higher
  __vector double prod = vec_sqrt(v);

I think this is a bug.
