/* 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.
