   1 ! REQUIRES: openmp_runtime

   3 ! Verify that the omp_lib.h header is found and included correctly. This header file should be available at a path:
   4 !   * relative to the driver, that's
   5 !   * known the driver.
   6 ! This is taken care of at the CMake and the driver levels. Note that when searching for header files, the directory of the current
   7 ! source file takes precedence over other search paths. Hence adding omp_lib.h in the current directory will make Flang use that
   8 ! header file instead of the one shipped with Flang.

  10 ! This should just work
  11 ! RUN: not rm omp_lib.h
  12 ! RUN: %flang -cpp -fsyntax-only %openmp_flags %s  2>&1
  13
  14 ! Create an empty omp_lib.h header that _does not_ define omp_default_mem_alloc - this should lead to semantic errors
  15 ! RUN: touch omp_lib.h
  16 ! RUN: not %flang -cpp -fsyntax-only %openmp_flags %s  2>&1 | FileCheck %s
  17 ! RUN: rm omp_lib.h
