Hi Nick,
  archures.c will just have the support for the target architecture
but our target architecture is ia64.. So, I dont think there is any
need to add line there.

Also, elfxx-ia64.c and elf64-ia64.c are almost same, where should I
add the code..  I ve added it to elf64-ia64.c for the time being..

objdump is not recognizing the file format ..

[root@localhost binutils]# ./objdump -s /root/Desktop/testcase/test.o
./objdump: /root/Desktop/testcase/test.o: File format not recognized

So, where can the changes be made to dump the object file information?
