   7 ! TEST 1: Both input files are processed (output is printed to stdout)
   8 ! RUN: %flang -E %s %S/Inputs/hello.f90 | FileCheck %s --match-full-lines -check-prefix=FLANG

  10 ! TEST 2: None of the files is processed (not possible to specify the output file when multiple input files are present)

  17 ! TEST 3: Both input files are processed
  18 ! This particular test case generates output files in the same directory as the input files. We need to copy the input files into a
  19 ! temporary directory to avoid polluting the source directory.
