I belive it is okay because the 'casted' non-volatile pointer is only used once. as in, there is never a non-volatile version of the pointer that is used in more than one place that the compiler might try to optimize out. Each use jhc will generate code that creates the pointer relative to the volatile physicalAddr so it won't be able to merge them.

Ah. It's good news for me. I understand that poke function spec isn't BUG. I will rewrite Cortex-M3 demo with extern_volatile.patch style. And Ajhc's volatile patch should be dropped. In my use case, ForeignData style doesn't be needed. Thank you for your time. -- Kiwamu Okabe
