estimate_size_and_time()

void ipa_call_context::estimate_size_and_time ( ipa_call_estimates * estimates, bool est_times = true, bool est_hints = true )

inherited

Fill in the selected fields in ESTIMATES with value estimated for call in
this context.  Always compute size and min_size.  Only compute time and
nonspecialized_time if EST_TIMES is true.  Only compute hints if EST_HINTS
is true.
