Advanced Performance Extensions (APX) expand the entire x86 instruction set with access to more registers and adds various new features that improve general-purpose performance.
For an extension like this - unlike most prior extensions - you’re best off with essentially an entirely separately compiled copy of the program/library. So IFUNC is a poor fit, even with peer optimization.
