Historically, we have told contributors that GnuWin32 is a pre-requisite because our tests depend on utilities such as sed, grep, diff, and more. However, Git on Windows includes versions of these utilities in its installation. Furthermore, GnuWin32 has not been updated in many years. For these reasons, it makes sense to have the ability to run llvm tests in a way that is both: a) Easier on the user (less stuff to install) b) More up-to-date (The verions that ship with git are at least as new, if not newer, than the versions in GnuWin32. We add support for this here by attempting to detect where Git is installed using the Windows registry, confirming the existence of several common Unix tools, and then adding this location to lit's PATH environment.

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