Record count data, for SPARC processors only.
This feature requires you to install the Binary Interface Tool (BIT), which is part of the Add-on Cool Tools for OpenSPARC, available at http://cooltools.sunsource.net/. BIT is a tool for measuring performance or test suite coverage of SPARC binaries.
The allowed values of option are
on– Turn on collection of function and instruction count data. Count data and simulated count data are recorded for the executable and for any shared objects that are instrumented and that the executable statically links with, provided that those executables and shared objects were compiled with the -xbinopt=prepare option. Any other shared objects that are statically linked but not compiled with the -xbinopt=prepare option are not included in the data. Any shared objects that are dynamically opened are not included in the simulated count data. The data is viewed in the Instruction-Frequency tab in Performance Analyzer, or with the er_print ifreq command.
off‐ Turn off collection of count data.
static– Generates an experiment with the assumption that every instruction in the target executable and any statically linked shared objects was executed exactly once. As with the -c on option, the -c static option requires that the executables and shared objects are compiled with the -xbinopt=prepare flag.
By default, turn off collection of count data. Count data cannot be collected with any other type of data.
