Chapter 8: Making Software Performance Measurements
Activity Performance Measurements
You can also use the local_symbols_in option with procedure symbols; this allows
you to measure activity related to the symbols defined in a single function or
procedure.
Restoring the Current Measurement
The performance_measurement_initialize restore command allows you to
restore old performance measurement data from the perf.out file in the current
directory.
If you have not exited and reentered emulation, you can add traces to a
performance measurement simply by entering another
performance_measurement_run command. However, if you exit and reenter the
emulation system, you must enter the performance_measurement _initialize
restore command before you can add traces to a performance measurement. When
you restore a performance measurement, make sure your current trace command is
identical to the command used with the restored measurement.
The restore option checks the emulator software version and will only work if the
perf.out files you are restoring were made with the same software version as is
presently running in the emulator. If you ran tests using a former software version
and saved perf.out files, then updated your software to a new version number, you
will not be able to restore old perf.out measurement files.
