Member Function Documentation

account_size_time()

void ipa_fn_summary::account_size_time	(	int	size,
		sreal	time,
		const ipa_predicate &	exec_pred,
		const ipa_predicate &	nonconst_pred_in,
		bool	call = false )

Record SIZE and TIME to SUMMARY.
The accounted code will be executed when EXEC_PRED is true.
When NONCONST_PRED is false the code will evaluate to constant and
will get optimized out in specialized clones of the function.
If CALL is true account to call_size_time_table rather than
size_time_table.
