◆ duplicate_from()

void ipa_cached_call_context::duplicate_from ( const ipa_call_context & ctx)

◆ equal_to()

bool ipa_call_context::equal_to ( const ipa_call_context & ctx)
inherited 
Return true if CTX describes the same call context as THIS.

◆ 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.
