Test using `FileCheck`

[v01dXYZ]

In LLVM, testing is done by generating IR using llc with a set of arguments and comparing the output with the expect result using FileCheck. Do you think this approach is a good way to test quadrants as well?

I don't know. I would need to see a case-study to have better understanding of good/bad points.

Are you thinking of retro-fitting this for existing functionality? Or are you thinking of using this approach for new changes you submit?

I'll take a closer look to IRNode, ProgramImpl, compile_to_offloads.cpp, .... I'll write a uber comment to explain the different IR passes. That way you can correct me.
