; Minor complication: after generating the LLVM IR, it was manually edited so
; that the 'f1()' call from f3 was reordered to appear between the two inlined
; f1 calls from f2. This causes f2's inlined_subroutine to use DW_AT_ranges,
; thus exercising range list generation/referencing which was buggy.
