Interesting. and kinda sad. and based on the comments an ongoing problem.
One hopes that ARM's ascendance would make "team x86-64" work in cooperative competition for better performance through compilers (it they can't through silicon).
- arthur2e5 5y agoAMD and recently Intel both moving to LLVM is a good step in that direction IMO. LLVM also already comes with a dispatcher, so hopefully they aren’t going to… do it again. Personally I’m more excited about being able to port __attribute__ rich code more easily. (IIRC Intel has tuned down the Cripple AMD thing in MKL around late 2020 by providing a specialized Zen code path. It was slower than what you get with the detection backdoor, but only slightly.)
