Thread: Help with macros

We are trying to perform performance calculation (CPU cycles taken) on our functions in code.
We want to do this with minimal changes in code.

So if we have somewhere:
print_hi("hello world");

We shall replace it with:
CALL(print_hi("hello world"));

where: CALL expands to:
#define CALL(a) get_ticks( ); a; get_ticks_and_compare()

// Where get_ticks( ), get_ticks_and_compare( ) implement the logic of calculating start and end cycles.

Now, the function being encapsulated may have return values. Say:
result=CALL(add(2,3));

So we change our CALL macro to:
#define CALL(a) (get_ticks( ), a); get_ticks_and_compare();

But we could also have 'a' getting called from a for-loop statement:
for (i = 0; i < add(b, c); i++)

In such a case, we cannot use ';' in the CALL expansion as it would invalidate the for statement.

Please suggest any good ways of writing the CALL( ) macro that can solve our purpose.
