Sorry if this is a stupid question, but does Apple Silicon (on the Mac, iPhone, and iPad) support ARMv8-A, ARMv8-M or ARMv9? Also, has Apple added any custom functionality to the instruction set found in Apple Silicon?
ARM instruction set version?
There are no armv9 parts from Apple yet. it's all arm64e/arm64 which are variants of ARMv8 I think. What's nice is fp16 conversions and other features often missing from Android are present.
Determining Instruction Set Characteristics
Interrogate the system for details about the instruction set.
