Description Mike Cvet 2006-11-23 15:35:19 UTC

Stepping into a function (library function, etc) without debuginfo means that 
the DwflLine returned is null and line-stepping will fail. 

Need to determine satisfactory default behaviour for this case.

        * RunState.java (setUpStep): If the DwflLine returned is null, perform
        an instruction step. Handles line stepping within frames without debug
        info. Temporary fix for #3575.
        * StackFrame.java (frameToString): Renamed from toString().

Something to keep in mind is the case of a signal delivery, and the handler 
being located in a section of code with debuginfo. That being the case, the 
stack would be:

[debuginfo code - local singal handler]

[non-debuginfo code - signal stuff]

[debuginfo code - rest of program]

The user may not necessarily want to skip over the handler, even though the 
signal delivery code is a non-debuginfo section. i

Another possibility is to just require a breakpoint set on handler code if that 
is the area of interest.
