For reference/discussion.
GCC complains about signed-vs-unsigned comparison. I'm actually surprised that `m_registers_count` is a `signed` integer, as I can hardly imagine a negative register count. I'm under the impression that we could change `m_register_count` fields to be unsigned, but that would be a larger change. Thoughts?
