What is the point of ensuring that the compiler does not

Because we can write ASM to tell the CPU not to. We don't have
any such ability for the compiler right now.
I think the question was: Why would you want to disable compiler
code motion for loads/stores which are not atomic, as the CPU
might ruin your assumptions anyway?
