I've worked on a project using MCA/llvm-mca and found the behaviour to be unintuitive and not explicitly documented anywhere afaik. It's used in llvm-mca/Views/ResourcePressureView.cpp:62 and reads the value via llvm::countr_zero there. I hope the comment is appreciated and the review doesn't cause any inconveniences.
