Function pointer for inline function C

inline void myfunction(){
    //something here
}

void main(){
    void (*p)(void);
    p = myfunction;
    p();
}

What kind of machine code different compilers can generate for this, and in what situations?

Yes - but it will depend on your compiler and its settings what side effects will occur:

There are various ways to define inline functions; any given kind of definition might definitely emit stand-alone object code, definitely not emit stand-alone object code, or only emit stand-alone object code if it is known to be needed. Sometimes this can lead to duplication of object code...

As your compiler will need the adress of the function, it will generate a stand alone copy of the object code.
