calling graphe

[Philippe E. <ph...@cl...>]

hi,

 What about calling graphe (not at short term ...) with oprofile. At least for
application compiled without -fomit-frame-pointer or with external data
which provide the necessary information. From the point of view of
overhead I think we can use two distinct NMI handler, the actual handler
is installed if user request for low-overhead profiling else if user request
for extended capabilities we can provide a second NMI handler.

P.S.: I will commit oprof_start in 2 or 3 days.
