[Dwarf-Discuss] question about variable locations from dwarf debugging information

[Fengwei Zhang]

Dear all,

I am working on a project which needs to get the variable location  
from executable application. I could use readelf and dwarfdump to  
output the text debugging information, including the variable  
locations. However, the debugging information is very complex. For  
example, variable location will be "DW_OP_fbreg: -32". It means some  
offset from stack base frame. In other words, I need to compute where  
the variable is based on the debugging information.
I am wondering: Is there any other tool which help me get the memory  
address of variables? Like "print variable_name" command in gdb, then  
I could get 0xff73d305.

If there is no such tool,  It would be great if some could tell me  
how to compute the variable locations from dwarf debugging  
information, or some links I could read helping me to do that.

I do appreciate it!

Regards,
