[PATCH,V2 0/1] Add PT_GNU_SFRAME segment

[Indu Bhagat]

Hello,

I've made the changes to reflect that the SFrame format is for generating stack
traces only (and not for unwinding) to the GNU gabi proposed patch.

I've also made the necessary documentation (code comments, doc files) changes
in binutils (to be posted there soon).  These changes, however, will be
available in the next GNU Binutils release.

Thanks,
