-c option

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 Sun Studio 12, 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. Data is recorded for the executable and for any shared objects that the executable statically links with, provided that those executables and shared objects were compiled with the -xbinopt=prepare flag. Any other shared objects that are statically linked but not compiled with the -xbinopt=prepare flag are not included in the data. Likewise, any shared objects that are dynamically opened are not included in the data. The data is viewed in the Instruction-Frequency tab in Performance Analyzer, or with the er_print ifreq command.

• 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.
