Hi,
I think it is time to remove support for INITIAL_FRAME_POINTER_OFFSET, which is
no longer
used by any target today. This removes a bunch of conditional code, and fixes
a few bits
in the documentation. I'd say that part of the documentation is quite out of
sync, but I just
have to stop somewhere.
Bootstrapped and reg-tested on x86_64-pc-linux.gnu
Is it OK for trunk?
Thanks
Bernd.
