            Bug ID: 93750
           Summary: Altivec and std=c++11
           Product: gcc
           Version: 10.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: junghans at votca dot org
  Target Milestone: ---

If I have a code like:
#include<altivec.h>
int main(){vector double x,y=vec_splats(1.0);x=vec_madd(y,y,y);return
vec_all_ge(y,x);}

It compiled gcc-9 (g++ -std=c++11 code.c), but fails with gcc-10 (without
"-std=c++11" gcc-10 will compile the code fine as well).

What is wrong here?
