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

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

  17 ! CHECK: error: Must have INTEGER type, but is REAL(4)
