Why visual studion 2015 sp3 doesn't generate code for this line

I noticed that visual studio community 2015 sp3 strangely does not create code for a single line(shown in code)(both debug and release). I minimized project and put code here.

#include "stdafx.h"

enum AMINZIPCMD { AMINZIP_RELEASE = 0 };
enum AMINZIPRESULT { AMINZIP_SUCCESS = 0, AMINZIP_FAILURE };
struct AMINZIP {
    unsigned __int32 m_cbSize;
    unsigned __int32 m_dwType;
};
#define DLL_EXPORT __declspec(dllexport) __stdcall
extern "C" {
    int DLL_EXPORT uAminZip(enum AMINZIPCMD iCmd, struct AMINZIP * pAminZip);
};

#define global_func

/*------------------------------------------------------------*/
global_func int DLL_EXPORT uAminZip(enum AMINZIPCMD iCmd, struct AMINZIP * pAminZip)
{
    //No code generated for this line
    if (pAminZip->m_cbSize != sizeof(*pAminZip)) AMINZIP_FAILURE;
    if (pAminZip->m_dwType != 718624670) return AMINZIP_FAILURE;
    return AMINZIP_SUCCESS;
}

int APIENTRY wWinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPWSTR lpCmdLine, int nCmdShow)
{
    struct AMINZIP aminzip;
    return uAminZip(AMINZIP_RELEASE, &aminzip);
}


/*------------------------------------------------------------*/

and assembly window for uAminZip function here

global_func int DLL_EXPORT uAminZip(enum AMINZIPCMD iCmd, struct AMINZIP * pAminZip)

00F016C9 C2 08 00             ret         8  

I created a fresh Win32 project and copied code to it, but the problem remains

Should the line contain the "return" statement?
