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 implement flat
profile/call graph profile using this approach ?
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 be using
hardware timer.
Once i can get a data run time on target. i can xfer
to host.
Any pointers regarding this would be useful.
Regards
ita
