Deallocate memory obtained from SDL_SIMDAlloc
void SDL_SIMDFree(void *ptr);
It is not valid to use this function on a pointer from anything but SDL_SIMDAlloc() or SDL_SIMDRealloc(). It can't be used on pointers from malloc, realloc, SDL_malloc, memalign, new, etc.
However, SDL_SIMDFree(NULL) is a legal no-op.
The memory pointed to by
ptr is no longer valid for access upon return, and may be returned to the system or reused by a future allocation. The pointer passed to this function is no longer safe to dereference once this function returns, and should be discarded.
