Kristina Bessonova 175bc341a3 [lit] Attempt for fix tests failing because of 'warning: non-portable path to file' This is an attempt to fix clang test failures due to 'nonportable-include-path' warnings on Windows when a path to llvm-project's base directory contains some uppercase letters (excluding a drive letter). The issue originates from 2 problems: * discovery.py loads site config in lower case causing all the paths based on __file__ and requested within the config file to be in lowercase as well, * neither os.path.abspath() nor os.path.realpath() (both used to obtain paths of config files, sources, object directories, etc) do not return paths in the correct case for Windows (at least consistently for all python versions). As os.path library doesn't seem to provide any relaible way to restore the case for paths on Windows, this patch proposes to use pathlib.resolve(). pathlib is a part of Python 3.4 while llvm lit requires Python 3.6.

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