; Test that address space inference works correctly for inttoptr/ptrtoint
; patterns when the pointer manipulation is within the preserved mask.
; For local memory, AMDGPU uses 2^32-aligned apertures, so only the lower
; 32 bits are safe to modify.
; For global memory, flat and global addresses are identical, so all 64
; bits are preserved.
