Ok. I was skimming through binutils ml archives for more info.
Basically I have implemented CFI emission in AVR-GCC
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=17994
I have no idea that somewhat similar changes are required in binutils
too. Upon that the manual examination of output appeared correct. I am
using binutils 2.20.1. Will see what happens on supporting the above
macros. I wish there is some kind of updated binutils internals
document like that of GCC's for some references.
Thanks Richard!
Anitha.
