Values must be 8 - byte aligned , and so on 值必须是8字节对的,以此类推。
Values must be 4 - byte aligned , 值必须是4字节对的,
For these aggregate types passed as a pointer including m128 , the caller - allocated temporary memory will be 16 - byte aligned 对于这些作为指针(包括_ _ m128 )传递的聚合类型,调用方分配的临时内存将是16字节对的。
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 对值必须是1 、 2或4 ,并且这意味着生成的值应假定地址分别是字节、双字节或四字节对的。
