Values must be 8 - byte aligned , and so on 值必須是8字節對的,以此類推。
Values must be 4 - byte aligned , 值必須是4字節對的,
For these aggregate types passed as a pointer including m128 , the caller - allocated temporary memory will be 16 - byte aligned 對于這些作為指針(包括_ _ m128 )傳遞的聚合類型,調用方分配的臨時內存將是16字節對的。
The value of alignment must be 1 , 2 , or 4 and means that the generated code should assume that the address is byte , double - byte , or quad - byte aligned , respectively 對值必須是1 、 2或4 ,并且這意味著生成的值應假定地址分別是字節、雙字節或四字節對的。
