The static analyzer is a research-based one, built upon the LLVM IR.
The analysis is founded
on a symbolic model (not an ML model) for concurrency bugs. And due to
the anonymity
requirements, I am afraid I cannot reveal further information.

If you meant AI tools, then at this stage, no. For this patch, I have
used AI tools to help phrase
the patch better, but I did not use them for code analysis.
