Description Anton Leherbauer CLA 2010-06-01 06:36:13 EDT 
From bug 293966 comment 1:

#define GVMIN( x, y )  ( (x) < (y) ? (x) : (y) )
#define DBG(x)     printf( "result is %f\n", x );

{
    float f1 = 2.0F;
    float f2 = 1.0F;
    float f3 = GVMIN(f1, f2); // hover f1 or f2: the expression is evaluated
                                  // 1.0F is shown
        DBG(f3)              // hover f3: nothing is shown!
}

The expression hover should be improved such that
- hovering over a macro argument evaluates the argument
- hovering over a macro name evaluates the macro expansion (not all debuggers 
  support that)
