Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

An Algorithm for Structuring Flowgraphs (1977) [pdf]
Rellic[0] is a decompiler that uses a similar, more modern approach to turn LLVM IR into goto-free C code

Decompiler Explorer
Rellic [1] implements an algorithm that generates goto-free control flows (citation in README), which would be a significant improvement against what Ghidra/IDA generates currently.
Unfortunately it looks like the maintenance state of the pieces around Rellic isn't very good, and it's quite rocket science to get it building. It doesn't have as much UI/GUI as Ghidra either so it's a bit far from accessible right now.

Q: Irreducible Control Flow Graph in current compilers?

Understanding Objective-C by transpiling it to C++
I have started to do the same thing with go but it's largely unfinished. The next thing I will try to do when I have some time is to implement goroutine with the new c++20 coroutines.
