Re: [PATCH] OpenMP, Fortran: Bugfix for omp_set_num_teams.

[Marcel Vollweiler]

Hi Jakub,

! { dg-do run }
! { dg-additional-options "-fdefault-integer-8" }

program set_num_teams_8
   use omp_lib
   omp_set_num_teams (42)
   if (omp_get_num_teams () .ne. 42) stop 1
end program

I modified your suggested test case a bit:

program set_num_teams_8
  use omp_lib
  use, intrinsic :: iso_fortran_env
  integer(int64) :: x
  x = 42
  call omp_set_num_teams (x)
  if (omp_get_max_teams () .ne. 42) stop 1
end program

I tested it with/without the fix and the test passed/failed as expected.

Hope, that's ok?
