Chapter 8: Making Software Performance Measurements
Activity Performance Measurements
Examples
To specify a trace depth of 512:
display trace depth 512 <RETURN>
To trace after any state, store all states, and count time:
trace counting time <RETURN>
To initialize activity performance measurements
• Use the performance_measurement_initialize command.
After you set up the trace command, you must tell the SPMT the address ranges on
which you wish to make activity measurements. This is done by initializing the
performance measurement. You can initialize the performance measurement in the
following ways:
•
•
•
•
•
Default Initialization
Entering the performance_measurement_initialize command with no options
specifies an activity measurement. If a valid symbolic database has been loaded,
the addresses of all global procedures and static symbols will be used; otherwise, a
default set of ranges that cover the entire processor address range will be used.
272
Default initialization (using global symbols if the symbols database is loaded).
Initialize with user-defined files.
Initialize with global symbols.
Initialize with local symbols.
Restore a previous performance measurement (if the emulation system has
been exited and reentered).
