C++ 左值引用、右值引用和指针在汇编层面的差别

	// 右值引用
	int&& rret = 1 + 2;
	00D01FDF  mov         dword ptr [ebp-18h],3  
	00D01FE6  lea         eax,[ebp-18h]  
	00D01FE9  mov         dword ptr [rret],eax 
	
	rret = 10;
	00D01FEC  mov         eax,dword ptr [rret]  
	00D01FEF  mov         dword ptr [eax],0Ah  

// 左值引用
	int& lret = rret;
	00D01FF5  mov         eax,dword ptr [rret]  
	00D01FF8  mov         dword ptr [lret],eax  
	
	lret = 10;
	00D01FFB  mov         eax,dword ptr [lret]  
	00D01FFE  mov         dword ptr [eax],0Ah 

	// 指针
	int* retp = &rret;
	00D02004  mov         eax,dword ptr [rret]  
	00D02007  mov         dword ptr [retp],eax  
	
	*retp = 10;
	00D0200A  mov         eax,dword ptr [retp]  
	00D0200D  mov         dword ptr [eax],0Ah  

	int a = rret;
	00962013  mov         eax,dword ptr [rret]  
	00962016  mov         ecx,dword ptr [eax]  
	00962018  mov         dword ptr [a],ecx  
	
	a = 10;
	0096201B  mov         dword ptr [a],0Ah

看上去 [左值引用]汇编和 [指针]汇编一样。
