Defined if (and only if) the compiler supports ARM NEON intrinsics.
Defined in <SDL3/SDL_intrin.h>
#define SDL_NEON_INTRINSICS 1
If 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 3.1.3.
