GDB/LLDB突破共享库

Question

在lldb，我得到help breakpoint set：

 -a <address-expression> (--address <address-expression>) 
     Set the breakpoint at the specified address. If the address maps uniquely to a particular binary, then the address will be converted to a "file" address, so that the 
     breakpoint will track that binary+offset no matter where the binary eventually loads. Alternately, if you also specify the module - with the -s option - then the 
     address will be treated as a file address in that module, and resolved accordingly. Again, this will allow lldb to track that offset on subsequent reloads. The 
     module need not have been loaded at the time you specify this breakpoint, and will get resolved when the module is loaded. 

和

 -r <regular-expression> (--func-regex <regular-expression>) 
     Set the breakpoint by function name, evaluating a regular-expression to find the function name(s). 

和

-s <shlib-name> (--shlib <shlib-name>) 
     Set the breakpoint only in this shared library. Can repeat this option multiple times to specify multiple shared libraries. 

现在我想在命令的结果中可找到的指定模块/ dylib的每个函数处设置断点。

以libobjc.A.dylib和MyOwn.dylib为例。我想下面的命令，但未能：

(lldb) breakpoint set -r libobjc.A.dylib 
Breakpoint 1: no locations (pending). 
WARNING: Unable to resolve breakpoint to any actual locations. 

(lldb) b +[ThunderManager load] 
Breakpoint 2: where = MyOwn.dylib`+[ThunderManager load] +16 at ThunderManager.m:20, address = 0x000000010489f274 

(lldb) breakpoint set -r MyOwn.dylib`* 
Breakpoint 3: no locations (pending). 
WARNING: Unable to resolve breakpoint to any actual locations. 

我想在模块libobjc.A.dylib或MyOwn.dylib，或任何其他特定加载的模块/共享库的所有功能lldb GET休息。如何在lldb中设置断点？

Answer 1

(lldb) break set -r . -s libobjc.A.dylib 

的-s选项接受一个共享库作为其值，并且这限制了断点指定的共享库。您可以多次指定-s选项以指定包含在断点搜索中的多个共享库。

-r选项的值是一个正则表达式;如果符号名称匹配该表达式，它将包含在断点中。 .匹配所有内容。
