Hello,
In this patch I added restrictions for conversions of pointers to different address spaces as explained below. OpenCLv2.0 C spec s6.5 adds __generic (unnamed) address space to be used as a place holder in case an address space is not known statically or multiple are intended to be used with the same fragment of code. All named address spaces (that existed in the previous OpenCL standards) except for __constant are subset of __generic one. Conversions between pointers of different address spaces are regulated by rules in s6.5.5 as follows: - The named address spaces ( __global, __local, and __private) can be converted to __generic implicitly. Generic -> named can only be done with an explicit cast. - Conversions between pointers of named address spaces are not allowed. - A pointer to the __constant address space can only be converted to a pointer to the __constant address space (either by an implicit cast or by an explicit one). This patch depends on the change submitted previously: https://www.mail-archive.com/[email protected]/msg109232.html Thanks, Anastasia
