Introducing Module Reachability: Focus on the Vulnerabilities That Matter
Module Reachability filters out unreachable CVEs so you can focus on vulnerabilities that actually matter to your application.
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.
The official lit documentation is in the man page, available online at the LLVM Command Guide: http://llvm.org/cmds/lit.html.
The lit source is available as part of LLVM, in the LLVM source repository: https://github.com/llvm/llvm-project/tree/main/llvm/utils/lit
Please browse the issues labeled tools:llvm-lit in LLVM's issue tracker for ideas on what to work on: https://github.com/llvm/llvm-project/labels/tools%3Allvm-lit
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
