Breakpoint on exceptions (equivalent of gdb's

2019-02-02 20:01发布

问题:

I am trying to use lldb for c++ debugging and I want to halt if an exception is thrown, like gdb's catch throw, and I cannot find an equivalent in the lldb documentation.

回答1:

In Xcode, you can set an Exception breakpoint (View > Navigators > Show Breakpoint Navigator, hit the + button in the bottom of the breakpoint list window to add a new breakpoint).

If you're using command line lldb, put a breakpoint on __cxa_throw for C++ exception throws, objc_exception_throw for Objective-C exception throws.

For all c++ exceptions: break set -E C++.



回答2:

Use break set -E c++ to break on all exceptions and break set -F std::range_error to break on a specific exception.



回答3:

I think breakpoint set -w <boolean> is the correct answer, you can use help breakpoint set to see the document.

And I fall into another question:how to set boolean value in lldb command line?

hoping any one can help me. the question was asked at here.
