Suppress Compiler warning Function declared never referenced

Question

So i have some code like this:

void foo (int, int);

void bar ( )
{
    //Do Stuff

   #if (IMPORTANT == 1)
       foo (1, 2);
   #endif

}

Answer 1

#define SUPPRESS_UNUSED_WARN(var) \
    int _dummy_tmp_##var = ((int)(var) & 0)

not work in IAR, change to this will work:

#define SUPPRESS_UNUSED_WARN(var) \
     void _dummy_tmp_##var(void) { (void)(var); }
