如何检查LLDB是否从共享库中加载了调试符号？

在Linux上，我使用

(gdb) i shared

在gdb和gdb中，*如果没有加载调试符号，则用星号打印一个库列表，如果加载则不带库的列表，例如：

0x0000000100c18660  0x0000000100c489a0  Yes (*)     /Users/anon/work/software/webrtc-audio-processing-0.1/build_darwin/../bin/darwin/lib/libwebrtc_audio_processing.0.dylib
0x0000000100c57ca0  0x0000000100c76978  Yes         /Users/anon/work/software/speex/speex/speex-1.2rc2/build_darwin/../bin/darwin/lib/libspeex.1.dylib

我发现在LLDB中我应该使用

(lldb) image list

做同样的事情。但是我得到了一个库列表，它对是否为lib加载调试符号没有任何帮助，例如：

[181] 19269C1D-EB29-384A-83F3-7DDDEB7D9DAD 0x00007fff8d2d3000 /System/Library/PrivateFrameworks/CoreWiFi.framework/Versions/A/CoreWiFi
[182] 8D7BA9BA-EB36-307A-9119-0B3D9732C953 0x00007fff879ee000 /System/Library/Frameworks/CoreBluetooth.framework/Versions/A/CoreBluetooth
[183] 6F03761D-7C3A-3C80-8031-AA1C1AD7C706 0x00007fff92e52000 /System/Library/PrivateFrameworks/DebugSymbols.framework/Versions/A/DebugSymbols

那么，如何检查LLDB是否加载了调试符号？

更新：我只是决定将(lldb) image lookup -vn <function>（感谢吉姆）的输出发布给其他人，以了解它的外观：

image lookup -vn Herqq::Upnp::HSsdp::init
