Hi all,


I'm writing a tool that will dump all the global & static variables
present in the object file in DWARF 2.0 format. I'm aiming to dump the
following information for each variable, Viz. Name, Physical
location(address) in memory, Size(in bits/bytes), and data type.


I got valuable information from the web site
  http://reality.sgi.com/davea/objectinfo.html
  ftp://sgigate.sgi.com/pub/dwarf


SGI website contains free source code to retrive various info from the
object file. But i didn't get any information regarding getting the
"address of a variable". I also went through the Dwarf 2.0 standard.
But that doesn't clearly say how to get this. I just know that this
information is present in the ".debug_loc" section of the object file.


Can anybody give me some hints as to how to retrieve the address &
data type of a variable from a DWARF 2.0 object file ??? Any
information regarding this would be of great help to me.


Thanks in advance,
Swamy
