------- Comment #4 from kauer at os dot inf dot tu-dresden dot de 2007-08-28 19:07 -------
Some comments from the outside:
(1) It should be possible to exchange the emmited call into a jmp, without
adding the function epilog.
(2) A proper backtrace is not generated on optimized sibling functions.
(3) http://gcc.gnu.org/ml/gcc-patches/2000-10/msg00180.html explains, that it
is hard to implement
