Abstract: I have been advocating breaking the arbitraty barriers between layers of my transformation hierarchy for decades, insisting for example that until the algorithm people talk to the microarchitects, we are never going to get the full benefit of what computing can provide. And, I have given examples such as predication where the compiler, the ISA and the microarchitect can get rid of the misprediction penalty of conditional branches. As long as Moore's Law gave us more and faster transistors, we could be lazy. But now that that is about to end, we need to look elsewhere for continued performance benefit. Ergo, my mantra: break the layers! ...to which my critics argue that portability will go out the window and economics will prevent industry from getting on board. To which I say: Economics Be Damned! I will explain why I believe this position makes sense.
