Defined if (and only if) the compiler supports ARM NEON intrinsics.
Defined in <SDL3/SDL_intrin.h>
#define SDL_NEON_INTRINSICS 1If this macro is defined, SDL will have already included <armintr.h> <arm_neon.h>, <arm64intr.h>, and <arm64_neon.h>, as appropriate.
This macro is available since SDL 3.2.0.
