Does this mean that if I have two inline asm statements, once which sets a condition-code/model-specific register, and one which reads that register, because neither read or write memory, we'd now be allowed to reorder them? I'm concerned that, because we use memory dependencies to track all dependencies, this will lead to us losing track of other register dependencies that we should otherwise track.
