[PATCH] D41651: AMDGPU: Add 32-bit constant address space

[Tim Renouf via Phabricator via llvm-commits]

tpr added a comment.

For LLPC we need to extend a 32 bit pointer to 64 bit either by a value supplied in an option/feature, or by using the high half of s_getpc. But we don't need to get that into this change -- we can add it later, as long as this change is structured to allow it.
