Currently, reduction operations with minus are not supported and trigger
<code>
error: The minus reduction operator is deprecated since OpenMP 5.2 and is not supported in the REDUCTION clause.
</code>
Such minus reductions are currently used in various production codes, so sticking to OpenMP 5.2 and not supporting them will break such applications and require source code changes.
I request supporting the minus operator in reductions, so that flang can compile such applications out of the box without source code changes in the applications.
Here is a small reproducer which just does a simple reduction loop over one array: [omp_minus_reproducer.F90.zip](https://github.com/user-attachments/files/21603939/omp_minus_reproducer.F90.zip)
