| 8 | /* OpenCLC v2.0 adds a set of restrictions for conversions between pointers to |
| 9 | * different address spaces, mainly described in Sections 6.5.5 and 6.5.6. |
| 10 | * |
| 11 | * It adds notion of overlapping address spaces. The main differention is that |
| 12 | * an unnamed address space is added, called '__generic'. Pointers to the |
| 13 | * generic address space can be interchangabley used with pointers to any |
| 14 | * other address space except for __constant address space (Section 6.5.5). |
| 15 | * |
| 16 | * Based on this there are 3 sets of tests: __generic, named (__global in this |
| 17 | * case), and __constant, that should cover all program paths for CL address |
| 18 | * space conversions used in initialisations, assignments, casts, comparisons |
| 19 | * and arithmetic operations. |
