"textContent": "ais523:\n\n> to allow races of atomic reads against non-atomic writes (i.e. effectively LLVM's model)\n\nThat is not LLVM's model. LLVM's model is that _all_ read-write races are allowed. So this includes non-atomic reads against atomic writes, and non-atomic reads against non-atomic writes. (Well, LLVM's model is something like that. Not even LLVM themselves know what their model is, so we probably shouldn't use the term \"LLVM's model\", though I am guilty of that myself.)\n\nThat's still an interesting claim you are making, if it is correct. Unfortunately I lack the time to verify those proofs.",
