The only exception (pointed out in this post) is leveraging SIMD instructions, which aren't nearly as well exploited by compilers. I doubt, of course, that this will last all that long, but for now there are too many subtle differences that might matter and totally different instruction sets between cpus and even generations.
- Agentlien 4y agoI feel like I've been hearing complaints that compilers aren't leveraging SIMD instructions for years. I wonder when this will be solved.
- ravi-delia 4y agoProbably a decade after the interfaces stabilize and everyone figures out which minor quirks of behavior they're willing to permit with the right optimization flag. As of now things are highly dependent on platform- I've had great luck with the older x86 SIMD sets, but on ARM there's still a ways to go.
