A widely-used close-source app uses OpenMP SIMD reductions. It would be great if this feature was implemented. Thanks!
```
module foo
implicit none
contains
subroutine bar(arr,n_elem)
integer i
integer n_elem
double precision arr(:),resul
resul=0d0
!$OMP SIMD REDUCTION(+:resul)
do i=1,n_elem
resul=resul+arr(i)*i
enddo
end subroutine bar
end module foo
```
```
% flang -fopenmp -c foo.f90
flang-21: warning: OpenMP support in flang is still experimental [-Wexperimental-option]
