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.
