One thing that volatile doesn't do is escape results that have been written to memory. The proposed blackbox intrinsic is modeled as reading and writing any pointed to memory, which is useful. I also think blackbox will be a lot easier for people to use than empty volatile inline asm and volatile loads and stores. That alone seems worth something. :) On Mon, Nov 9, 2015 at 6:04 PM, Daniel
