爲什麼visual studion 2015 sp3不會爲此行生成代碼

我注意到Visual Studio社區2015 sp3奇怪地不會爲單行（代碼顯示）（調試和發佈）創建代碼。我最小化了項目並將代碼放在這裏。爲什麼visual studion 2015 sp3不會爲此行生成代碼

#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); 
} 


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

和組裝窗口uAminZip功能這裏

global_func int DLL_EXPORT uAminZip(enum AMINZIPCMD iCmd, struct AMINZIP * pAminZip) 
{ 
00F01690 55     push  ebp 
00F01691 8B EC    mov   ebp,esp 
00F01693 81 EC C0 00 00 00 sub   esp,0C0h 
00F01699 53     push  ebx 
00F0169A 56     push  esi 
00F0169B 57     push  edi 
00F0169C 8D BD 40 FF FF FF lea   edi,[ebp-0C0h] 
00F016A2 B9 30 00 00 00  mov   ecx,30h 
00F016A7 B8 CC CC CC CC  mov   eax,0CCCCCCCCh 
00F016AC F3 AB    rep stos dword ptr es:[edi] 
    if (pAminZip->m_cbSize != sizeof(*pAminZip)) AMINZIP_FAILURE; 
    if (pAminZip->m_dwType != 718624670) return AMINZIP_FAILURE; 
00F016AE 8B 45 0C    mov   eax,dword ptr [pAminZip] 
00F016B1 81 78 04 9E 57 D5 2A cmp   dword ptr [eax+4],2AD5579Eh 
00F016B8 74 07    je   uAminZip+31h (0F016C1h) 
00F016BA B8 01 00 00 00  mov   eax,1 
00F016BF EB 02    jmp   uAminZip+33h (0F016C3h) 
    return AMINZIP_SUCCESS; 
00F016C1 33 C0    xor   eax,eax 
} 
00F016C3 5F     pop   edi 
00F016C4 5E     pop   esi 
00F016C5 5B     pop   ebx 
00F016C6 8B E5    mov   esp,ebp 
00F016C8 5D     pop   ebp 
00F016C9 C2 08 00    ret   8

我創建了一個新的Win32項目並複製代碼，但問題仍然存在

如若行包含「返回」語句？

沒錯。我應該寫回到那裏。謝謝 –
