Note

If your code contains calls to I/O functions and has been linked with the C-SPY debug library, performance analysis will not work correctly because of internal breaks. To use performance analysis, you must either be sure that your code does not contain any calls to I/O functions or that you have disabled the linker option Include C-SPY debugging support on the Project>Options>Linker>Library page. On the command line, this is the linker option --debug_lib.
