Hello,
I am trying to explore the gcc 's profiling support.It
is has great support for instrumenting application
with profiling code.
It is quiet useful for me. but it uses profil()/
settimer functionality to generate the time signal in
native gcc.
I am afraid profil() or settimer functional support is
not there for the targets without any OS sitting on
it.
How does the profiling works on other embedded targets
in gcc world?
I have global counter unit on the hardware. If i use
this in prologue and epilogue of function . I can get
the time spend in the function.
Can I make a use of this to replace profil()
functionality ? I want to replace native calls mcount
and monstartup
with my code which will using hardware timer. Can I
get implement flat profile/call graph profile
Any pointers regarding this would be useful.
-regards,
ita
