D80519 <https://reviews.llvm.org/D80519> added support for `DW_TAG_GNU_call_site` but Bug 45886 <https://bugs.llvm.org/show_bug.cgi?id=45886> found one case did not work.
There is:

  0x000000b1:     DW_TAG_GNU_call_site
                    DW_AT_low_pc  (0x000000000040111e)
                    DW_AT_abstract_origin (0x000000cc "a")
  0x000000cc:   DW_TAG_subprogram
                  DW_AT_name      ("a")
                  DW_AT_prototyped        (true)
                  DW_AT_low_pc    (0x0000000000401109)
                  ^^^^^^^^^^^^ - here it did overwrite the 'low_pc' variable containing value 0x40111e we wanted
                  DW_AT_high_pc   (0x0000000000401114)
                  DW_AT_frame_base        (DW_OP_call_frame_cfa)
                  DW_AT_GNU_all_call_sites        (true)
