I would not say 100% reliable, but more reliable - there are two issues with
-pg profiling: one is cache footprint of mcount, the other is that gcc at
the moment calls mcount only on function entry and not exit, so that means
the times you get for functions include parent function context till next
function is invoked.
Cheers,
Jakub
