This converter currently only handles global variables in address space 0. For these variables, they are promoted to address space 1 (global memory), and all uses are updated to point to the result of a cvta.global instruction on the new variable. The motivation for this is address space 0 global variables are illegal since we cannot declare variables in the generic address space. Instead, we place the variables in address space 1 and explicitly convert the pointer to address space 0. This is primarily intended to help new users who expect to be able to place global variables in the default address space. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@182254 91177308-0d34-0410-b5e6-96231b3b80d8
