execution against time using X Window System and OSF/Motif on a Sun-4 or Microsoft Windows on
a PC.
As with the execution profiler, the user program is monitored by a profiling kernel. The kernel will slow
the program by less than 5%.
4.3
This tool monitors test coverage and performs block profiling for an application which has been run
on target hardware.
This tool is able to:
The application program (compiled with the appropriate compiler option) is run and accumulates the
counts in the memory of the target processor. The tool is used to extract the results and save,
accumulate or display them. This application writes the counts into the code area, so the tool cannot
be used with code running from ROM.
The following is an example of the contents of a coverage file:
Test coverage and block profiling tool
provide an overall test coverage report;
provide per module test coverage reports;
accumulate a single report from multiple test runs;
provide a detailed basic block profiling output by creating an annotated program listing;
provide output that can be fed back into the compiler as a part of its optimization process.
