; DESCRIPTION:
;
; The kernel 'kern' makes a call to declared only function `foo`, hence `foo`
; is not considered as reachable callee, and is ignored. The function `goo`
; which uses LDS is not called from kernel 'kern', hence it is also ignored.
;
; Original LDS should exist.
; CHECK: @lds = internal local_unnamed_addr addrspace(3) global i32 undef, align 4
@lds = internal local_unnamed_addr addrspace(3) global i32 undef, align 4
; Pointer should not be created.
; CHECK-NOT: @lds.ptr = internal unnamed_addr addrspace(3) global i16 undef, align 2
; CHECK: declare i32 @foo()
declare i32 @foo()
; No change
