And you misunderstand me. Your proposal means, that the compiler, must emit an individual access with the right values at the right time. If an access may succeed or fail, then the compiler can not just convert it into an aligned read, or not a read at all. If your proposal includes, that a trapping access gets treated by the compiler as if it didn't and the compiler emits code that performs all kind of side-effects, that are logically independent if it would not trap, before the access, then you are back to undefined behaviour under a different name. |
