hum, should you also remove the following code? if (!bfd_check_format(abfd, bfd_object)) { pr_debug2("%s: cannot read %s bfd file.\n", __func__, debugfile); goto out_close; } if (bfd_get_flavour(abfd) == bfd_target_elf_flavour) goto out_close; it seems to be called already above thanks, jirka > if (!bfd_check_format(abfd, bfd_object)) { > pr_debug2("%s: cannot read %s bfd file.\n", __func__, > debugfile); > -- > 2.30.0 >
