flang/test/Semantics/event01b.f90

   1 ! RUN: %python %S/test_errors.py %s %flang_fc1
   2 ! This test checks for semantic errors in event post statements based on the
   3 ! statement specification in section 11.6.7 of the Fortran 2018 standard.
   4 ! Some of the errors in this test would be hidden by the errors in
   5 ! the test event01a.f90 if they were included in that file,
   6 ! and are thus tested here.
