手动加载UiApp.dll的调试符号

2024.04.10
在UEFI的log打印中，可以看到UiApp已经被加载，但lm命令没有列出。
add-symbol-file /home/geduer/UEFI/edk2-yourland2024/workspace/Build/YourLand/DEBUG_GCC/AARCH64/MdeModulePkg/Application/UiApp/UiApp/DEBUG/UiApp.dll 0xE9E75000
Loading driver at 0x000E9E74000 EntryPoint=0x000E9E7C6C0 UiApp.efi

.reload UiApp.dll=0`E9E74000,0`2A600

此处下断点：
DxeCore!CoreLoadImageCommon.constprop.0+12b0:
3ec436fc d2800880 mov    x0, #0x44
3ec43700 97ffce67 bl    #0x3ec3709c

3ec43718 d2800880 mov    x0, #0x44

加载上符号，调用栈里终于看到UiApp
