+void __ovld atomic_init(volatile __global atomic_int *object, int value);
----------------
Sorry, I overlooked that. Not //elif//, just //if// as these are available in 3.0 even with generic address space feature (https://www.khronos.org/registry/OpenCL/specs/3.0-unified/html/OpenCL_C.html#the-atomic_init-function):

```
// Requires OpenCL C 3.0 or newer.
void atomic_init(volatile __global A *obj, C value)
void atomic_init(volatile __local A *obj, C value)

// Requires OpenCL C 2.0, or OpenCL C 3.0 or newer and the
// __opencl_c_generic_address_space feature.
void atomic_init(volatile A *obj, C value)
```
