Detailed Description

This object describe a context of call.  That is a summary of known
information about its parameters.  Main purpose of this context is
to give more realistic estimations of function runtime, size and
inline hints.

Constructor & Destructor Documentation

◆ ipa_call_context() [1/2]

ipa_call_context::ipa_call_context	(	cgraph_node *	node,
		clause_t	possible_truths,
		clause_t	nonspec_possible_truths,
		vec< inline_param_summary >	inline_param_summary,
		ipa_auto_call_arg_values *	arg_values )

Main constructor for ipa call context.  Memory allocation of ARG_VALUES
is owned by the caller.  INLINE_PARAM_SUMMARY is also owned by the
caller.

Member Function Documentation

◆ equal_to()

bool ipa_call_context::equal_to ( const ipa_call_context & ctx )

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 )

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.
