 | /* 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 |
