为什么参数存储在x86-64 Assembly中的寄存器中而不是堆栈中?
问题描述：
在x86-32组件中，参数存储在堆栈中，而在x86-64中，参数存储在寄存器中.是什么原因呢?
In x86-32 assembly, parameters are stored on the stack but in x86-64, parameters stored in registers. What is the reason for this?
答
访问CPU寄存器比访问RAM快很多.
It is (a lot) faster to access CPU registers than to access RAM.
由于64位CPU具有更多的通用寄存器(与64位无关，只是因为它们是更新/更大的)，因此使用它们是有意义的.
Since 64bit CPU have a lot more general purpose registers (has nothing to do with being 64bit, it's just because they are newer/bigger), it makes sense to make use of them.
