How do I make best use of the NEON operations for the M1 processor in my C code project in Xcode? Do I need to add the Arm Performance Libraries, or is this handled automatically - or is there a third alternative? Where can I find an overview of the available intrinsics? Thanks

As I know, there are two options. One, Aarch64 assembly. You can write inline assembly or call assembly function in C project. Two, NEON intrinsics. Include <arm_neon.h> to use NEON. Clang will transfer the intrinsics to low level instructions.
