Joel E. Denny cb2c4bb0e0 [lit] Fix internal env calling env Without this patch, when using lit's internal shell, if `env` on a lit RUN line calls `env`, lit accidentally searches for the latter as an external executable. What's worse is that works fine when a developer is testing on a platform where `env` is available and behaves as expected, but it then breaks on other platforms. `env` calling `env` can make sense if one such `env` is within a lit substitution, as in D65156 and D65121. This patch ensures that lit executes both as internal commands. Reviewed By: probinson, mgorny, rnk Differential Revision: https://reviews.llvm.org/D65697		2019-11-01 14:08:52 -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
