Summary: Before making this change, whenever I ran "check-flang", I'd get an error message like: llvm-lit: /mnt/c/GitHub/f18/c751/flang/build/bin/../../../llvm/utils/lit/lit/main.py:252: warning: Failed to delete temp directory '/tmp/lit_tmp_gOKUIh' With this change, there's no such message in the output, and the temp directory is successfully removed. Note that my working environment is on Windows 10 running Windows Subsystem for Linux using the Ubuntu app. I'm running Python version 2.7.1. Earlier versions of Python do not contain `shutil`. It may be that this module was available on Windows systems later than other platforms. Upgrading my version of Python made the problem go away I don't believe that timing was a problem since inserting a long delay didn't fix things. So I added some text to the error message recommending that the user upgrade their version of Python if they run into this problem.

===============================
lit - A Software Testing Tool
===============================
lit is a portable tool for executing LLVM and Clang style test suites,
summarizing their results, and providing indication of failures. lit is designed
to be a lightweight testing tool with as simple a user interface as possible.
=====================
Contributing to lit
=====================
Please browse the Test Suite > lit category in LLVM's Bugzilla for ideas on
what to work on.
Before submitting patches, run the test suite to ensure nothing has regressed:
# From within your LLVM source directory.
utils/lit/lit.py \
--path /path/to/your/llvm/build/bin \
utils/lit/tests
Note that lit's tests depend on 'not' and 'FileCheck', LLVM utilities.
You will need to have built LLVM tools in order to run lit's test suite
successfully.
You'll also want to confirm that lit continues to work when testing LLVM.
Follow the instructions in http://llvm.org/docs/TestingGuide.html to run the
regression test suite:
make check-llvm
And be sure to run the llvm-lit wrapper script as well:
/path/to/your/llvm/build/bin/llvm-lit utils/lit/tests
Finally, make sure lit works when installed via setuptools:
python utils/lit/setup.py install
lit --path /path/to/your/llvm/build/bin utils/lit/tests
