line coverage with gcov

[ciroceissler]

hello,

 

I trying to do coverage using gcov and can't reach 100% for line coverage, for example:

 

#####:  32: SC_MODULE(test) {

        -:   33:        sc_in<bool> clk;

        -:   34:        sc_in<bool> arst_n;

        -:   35:  

        -:   36:        void func1 ();

        -:   37:        void func2 ();

        -:   38:

      18:  39:        SC_CTOR(test)  {

      18:  40:                SC_CTHREAD(func1, clk.pos())

      18:  41:                async_reset_signal_is(arst_n, false);

        -:   42:

      18:  43:                SC_CTHREAD(func2, clk.pos());

      18:  44:                async_reset_signal_is(arst_n, false);

        -:   45:

        -:   46:        } // end of SC_CTOR

        -:   47: }; // end of SC_MODULE

 

From other project, I have another behavior (just put a stub from module), here above:

 

      18:  32: SC_MODULE(test2) {

        -:   33:        sc_in<bool> clk;

        -:   34:        sc_in<bool> arst_n;

        -:   35:  

      18:   36:        void func1 ();

      18:   37:        void func2 ();

        -:   38:

      18:  39:        SC_CTOR(test2)  {

      18:  40:                SC_CTHREAD(func1, clk.pos())

      18:  41:                async_reset_signal_is(arst_n, false);

        -:   42:

      18:  43:                SC_CTHREAD(func2, clk.pos());

      18:  44:                async_reset_signal_is(arst_n, false);

        -:   45:

        -:   46:        } // end of SC_CTOR

        -:   47: }; // end of SC_MODULE

 

I don't understand why SC_MODULE wasn't covered from the first example, but SC_CTOR was.

 

Can anyone tell me why this happen or could suggest another tool for coverage?

gcov only reach SC_MODULE line when the destructor is called, look at gdb results:

 

"Breakpoint 1, ~test2 (this=0x7fff8447a790) at test2.h:29"

 

So, I use 'return 0;' instead of 'exit(SUCCESS);' at sc_main from the first project.
