Chapter 8: Making Software Performance Measurements
Duration Performance Measurements
Or:
trace after module_name start or module_name end only
module_name start or module_name end counting time
<RETURN>
Where "symbol_entry" and "symbol_exit" are symbols from the user program. Or,
where "module_name" is the name of a C function or Pascal procedure (and is
listed as a procedure symbol in the global symbol display).
Examples
To specify a trace display depth of 512:
display trace depth 512 <RETURN>
To set up the trace command for duration measurements on the interrupt_sim
function:
trace after interrupt_sim start or interrupt_sim end
only interrupt_sim start or interrupt_sim end counting
time <RETURN>
The trace specification sets up the analyzer to capture only the states that contain
the start address of the interrupt_sim function or the end address of the
interrupt_sim function. Since the trigger state is also stored, the analyzer is set up
to trigger on the entry or exit address of the interrupt_sim function. With these
states in memory, the analyzer will derive two measurements: time from start to
end of interrupt_sim, and time from end to start of interrupt_sim.
