atos给出___lldb_unnamed_function

我有一个崩溃转储，它不会正常符号化 - 当我将它拖入Xcode组织器或手动运行symbolicatecrash时，系统符号会显示，但应用程序指令地址都不受影响 .

我尝试使用atos来解决这个问题，但我得到的结果是：

got symbolicator for myarchive.xcarchive/Products/Applications/MyApp.app/MyApp, base address 4000
___lldb_unnamed_function2115$$MyApp (in MyApp) + 992
___lldb_unnamed_function2096$$MyApp (in MyApp) + 66
___lldb_unnamed_function6053$$MyApp (in MyApp) + 348
___lldb_unnamed_function6064$$MyApp (in MyApp) + 162
___lldb_unnamed_function6002$$MyApp (in MyApp) + 18
___lldb_unnamed_function1029$$MyApp (in MyApp) + 416
___lldb_unnamed_function2280$$MyApp (in MyApp) + 106
___lldb_unnamed_function2272$$MyApp (in MyApp) + 198
___lldb_unnamed_function400$$MyApp (in MyApp) + 96
___lldb_unnamed_function1$$MyApp (in MyApp) + 36

当前映射到 ___lldb_unnamed_function1$$MyApp (in MyApp) + 36 的地址应该与main.m中的根调用相对应 . 显然，我不会猜测，如果一个人错了，他们就错了 . 什么可能导致这个？ ___lldb_unnamed_function是否通常出现在块中嵌入的函数以外的任何位置？

不幸的是，这将会产生一个很长的问题，但由于在计算应用程序二进制文件的负载偏移量时可能会出错，因此我将列出我执行上述输出所遵循的步骤 .

我使用 dwarfdump -u myarchive.xcarchive/Products/Applications/MyApp.app/MyApp 来验证我使用的是正确的二进制文件：

UUID: BA41E9A3-4BB5-3F8A-8D57-0D16447FFEC6 (armv7) myarchive.xcarchive/Products/Applications/MyApp.app/MyApp

UUID: A6E0970C-05FE-3A79-887D-84F3892637FD (armv7s) myarchive.xcarchive/Products/Applications/MyApp.app/MyApp

崩溃转储中的UUID与第一个匹配：

Binary Images:
   0x97000 -   0x3cefff +MyApp armv7  <ba41e9a34bb53f8a8d570d16447ffec6> /var/mobile/Applications/AF97EC52-7A2F-4772-AA05-74E739BA6882/MyApp.app/MyApp

该行还将负载偏移列为0x97000，架构为armv7 . 我感兴趣的地址是：

1   MyApp                               0x001357dc 0x97000 + 649180
2   MyApp                               0x00134446 0x97000 + 644166
3   MyApp                               0x00240cec 0x97000 + 1744108
4   MyApp                               0x002416ea 0x97000 + 1746666
5   MyApp                               0x0023e2de 0x97000 + 1733342
6   MyApp                               0x000de724 0x97000 + 292644
7   MyApp                               0x00144f1a 0x97000 + 712474
8   MyApp                               0x00144336 0x97000 + 709430
27  MyApp                               0x000b1024 0x97000 + 106532
28  MyApp                               0x0009d464 0x97000 + 25700

所以我跑了 xcrun atos -l 0x97000 -arch armv7 -o myarchive.xcarchive/Products/Applications/MyApp.app/MyApp 0x001357dc 0x00134446 0x00240cec 0x002416ea 0x0023e2de 0x000de724 0x00144f1a 0x00144336 0x000b1024 0x0009d464 ，它给了我上面的输出 .

注意：由于这看起来不正确，我想也许我需要手动减去幻灯片值 . 我从 xcrun otool -arch armv7 -l myarchive.xcarchive/Products/Applications/MyApp.app/MyApp 的应用程序包中获取了它：

Load command 0
      cmd LC_SEGMENT
  cmdsize 56
  segname __PAGEZERO
   vmaddr 0x00000000
   vmsize 0x00004000
  fileoff 0
 filesize 0
  maxprot 0x00000000
 initprot 0x00000000
   nsects 0
    flags 0x0
Load command 1
      cmd LC_SEGMENT
  cmdsize 736

  fileoff 0
 filesize 3375104
  maxprot 0x00000005
 initprot 0x00000005
   nsects 10
<snip>

但是，使用-l 0x93000重新运行命令给了我一个非常相似的结果：
