Debugger question. Step on variable operation

Alexey Kuz

Hi

Why I can't step on all operation with variable? I can't put label on that lines. Only one stoppable line - last one (while). There is only one function in one file of project.

void main (void)
{
         int i;
        int su;

        i = 0;
        su = 0;

        i++;
        su =i+1;

  while (1) ;
}


Why?

    Hence the NASA maxim, "Debug what you fly; fly what you debugged"

    It is possible to debug optimised code - but it's harder work.

    However, if you don't understand what the optimiser's doing, how can you be sure that it'll still work...?

    It's very reasonable for NASA!

    But my application is not so complicated and critical. I just need to make application that works as fast as possible. And I can always decide if my application works right by user output on LCD screen.
