[PATCH] D59440: add steps to preprocess file and reduce command line args

[Reid Kleckner via Phabricator via cfe-commits]

rnk added inline comments.


================
Comment at: clang/utils/creduce-clang-crash.py:106-117
+  # Check that an empty file is not interesting
+  # file_to_reduce is hardcoded into the test, so this is a roundabout
+  # way to run it on an empty file
+  _, tmpfile = tempfile.mkstemp()
+  _, empty_file = tempfile.mkstemp()
+  shutil.copy(file_to_reduce, tmpfile)
+  shutil.copy(empty_file, file_to_reduce)
----------------
Another way to do this without the complexity of swapping the files around is to construct the interestingness test to take the path to the file as a parameter (`$1`). CReduce always passes the path to the file being reduced as the first argument.
