Quantify simulates the time required to handle register window overflow and underflow conditions for SPARC processors. For more information, read How Quantify times register-window traps.
To control recording these simulated times, use the option -record-register-window-traps. For example:
You can find the cost in machine cycles that Quantify uses for each register-window underflow and overflow trap in the .machine.solaris2 file in <quantifyhome>.
By default, -record-register-window-traps=no. Quantify reports the excluded register-window trap time only if it is a significant fraction of the combined recorded and excluded time for the entire run.
On machines such as HPPA which do not support register windows, Quantify ignores any attempts to time these operations and issues a warning message.
