Nico Weber 9b22d9cf53 Revert "[lit] Keep original cfg file case around." This reverts commit bc3f54de1827e58655c34477d09211cbc42589bd. The patch breaks in the following two scenarios: 1. When manually passing an absolute path to llvm-lit with a lower-case drive letter: `python bin\llvm-lit.py -sv c:\llvm-project\clang\test\PCH` 2. When the PWD has a lower-case drive letter, like after running `cd c:\` with a lower-case "c:" (cmd's default is upper-case, but it takes case-ness from what's passed to `cd` apparently).		2020-04-15 17:19:39 -04:00

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