213 Return the pointer to the first instruction of a function given a function pointer.
214 On IA32 CPU architectures, these two pointer values are the same,
215 so the implementation of this macro is very simple.
217 @param p A pointer to a function
219 @return The pointer to the first instruction of a function given a function pointer.
221 #define FUNCTION_ENTRY_POINT(p) (p)
