Aaron Smith 55218b8d96 [lit] Fix several Python 2/3 compatibility issues and tests - In Python 2.x, basestring is the base string type, but in Python 3.x basestring is not defined and instead str includes unicode strings. - When Python is in a path that includes spaces, it needs to be specified with quotes in the test files for it to run. - The cache.ll test relies on files of a specific size being created by Python, but on some versions of Windows the files that are created by the current code are one byte larger than expected. To fix the test, update file creation to always make files of the expected size. Patch by Stella Stamenova! llvm-svn: 329466		2018-04-07 00:21:28 +00:00

===============================
 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
