; The above should produce an ADRP/ADD pair to calculate the address of
; testfn. The important point is that LLVM shouldn't think it can deal with the
; relocation on the ADRP itself (even though it knows everything about the
; relative offsets of testfn and foo) because its value depends on where this
; object file's .text section gets relocated in memory.
