flang/test/Frontend/prescanner-diag.f90

! Test that the driver correctly reports diagnostics from the prescanner, no
! matter what driver action/phase is run. We need this test as Flang currently
! has no central API for managing the diagnostics. For this reason the driver
! needs to make sure that the diagnostics are indeed issued (rather that relying
! on some DiagnosticsEngine).

! Test with -E (i.e. PrintPreprocessedAction, stops after prescanning)
! RUN: %flang -E -I %S/Inputs/ %s 2>&1 | FileCheck %s

! Test with -fsyntax-only (i.e. ParseSyntaxOnlyAction, stops after semantic checks)
