Oh I see. You were talking about a compiler for software talking to hardware. Well, I don't see why talking to hardware is any different to talking to a CPU or main memory or a disk.

Not so much "talking" as directly reading/writing memory outside of your source scope that is also mutated by other chips--like a DMA buffer.

Or for a traditional kernel, reading/writing directly into the address space of a user process. Wouldn't have to worry so much about race conditions there since the process could be suspended, but there is still an opportunity to fudge the indexing.
