I'm totally cool with this change; however, it's been a while since I've taken a look at this part of MCA. I'll let other's chime in as well, but +1 from me.

Thanks for taking a look. Would you be okay with making the status message() in FindPythonInterpAndLibs.cmake and FindLuaAndSwig.cmake fatal, that way the dependency error is clearer?

That would defeat the purpose of auto-detecting these dependencies. Please take a look at D71306 for all the details. The summary is that all optional dependencies default to Auto: where we enable them if we can find them. You can override this behavior by passing LLDB_ENABLE_PYTHON=ON to CMake, in which case not finding Python (or SWIG) will be a fatal error.

Hi @uabelho

The test case in your patch definitely causes a problem, but that's because the -start-before/-stop-after is used. If I run that same test through llc, the UnreachableBlockElim pass kicks-in and drops the dead code.
I took a look at the code in your Janurary 24th comment. I was unable to get the same dead block to surface, but most likely I had the wrong flag set. How did you build the sample in that comment?

It can be reproduced with the full llc -O1 pipe on current trunk using:
