Description

The generic address space requires support for either OpenCL C 2.0, or OpenCL C 3.0 or newer with the __opencl_c_generic_address_space feature. It can be used with pointer types and it represents a placeholder for any of the named address spaces - global, local or private. It signals that a pointer points to an object in one of these concrete named address spaces. The exact address space resolution can occur dynamically during the kernel execution.

kernel void foo(int a)
{
    private int b;
    local int c;
    int* p =  a ? &b : &c; // p points to the local or private address space.
}
