Hi, Gireesh.  If you're using a Linux system, or using Cygwin on
windows, you will probably have  a program called 'readelf'.  If you
have an object file or executable with DWARF information in it,
'readelf -wi' will display the DWARF information in a human-readable
form.  You should try compiling various programs, and then looking at
the DWARF information they produce.

I don't think we have information in a more pre-digested form than the
DWARF spec itself.  It's big, but it's not impossible to read.
