[Sivaguru Sankaridurg]

Hi,


I complied the program shown below (a.cc) and ran objdump on it as
shown below.

address@hidden (60) ~» gcc -v
Reading specs from 
/usr/local/gcc-2.95.3/lib/gcc-lib/i686-pc-linux-gnu/2.95.3/specs
gcc version 2.95.3 20010315 (release)



address@hidden (60) ~» gcc -g a.cc


address@hidden (60) ~» objdump --v
