; DESCRIPTION ;
;
; LDS global @not-reachable-lds is used within non-kernel function @f0, but @f0 is *not*
; reachable from kernel @k, hence pointer replacement does not take place.
;

; CHECK: @not-reachable-lds = internal addrspace(3) global [4 x i32] undef, align 4
@not-reachable-lds = internal addrspace(3) global [4 x i32] undef, align 4

; CHECK-NOT: @not-reachable-lds.ptr
