> The define and the static inline functions are not equivalent at all.
Right, in general, but if the expressions are side-effect-free,
gcc could move their evaluation farther down.

------- Comment #1 from pinskia at gcc dot gnu dot org 2009-05-20 15:21 -------
The define and the static inline functions are not equivalent at all.
#define evaluate(val) \
do { \
typeof(val) tmpval = val; \
if (unlikely(enabled)) { \
printf("value is: %d\n", tmpval); \
} \
} while (0)
makes the define equivalent to the static inline funciton.
