! TEST 2: `-o` does not work for `flang-new` when multiple input files are present
! ERROR:error: cannot specify -o when generating multiple output files
! TEST 3 & TEST 4: Unless the output file is specified, `flang-new -fc1` generates one output file for every input file. If an
! output file is specified (with `-o`), then only the last input file is processed.
