/* OpenCLC v2.0 adds a set of restrictions for conversions between pointers to
*  different address spaces, mainly described in Sections 6.5.5 and 6.5.6.
*
*  It adds notion of overlapping address spaces. The main differention is that
*  an unnamed address space is added, called '__generic'. Pointers to the
*  generic address space can be interchangabley used with pointers to any
*  other address space except for __constant address space (Section 6.5.5).
*
*  Based on this there are 3 sets of tests: __generic, named (__global in this
*  case), and __constant, that should cover all program paths for CL address
*  space conversions used in initialisations, assignments, casts, comparisons
*  and arithmetic operations.
*
*  OpenCLC v3.0 supports generic address if __opencl_c_generic_address_space feature is supported
