marker：x86-64寄存器参数详解
一、x86-64寄存器参数列表
| 寄存器名称 | 寄存器功能 |
| %rsp | 堆栈指针寄存器，指向栈顶位置。pop操作通过增大rsp的值实现出栈，push操作通过减小rsp的值实现入栈。 |
| %rbp | 栈帧指针，标识当前栈帧的起始位置。 |
| %rax | 通常存储函数调用的返回结果，也被用在idiv （除法）和imul（乘法）命令中。 |
| %rdi, %rsi, %rdx, %rcx,%r8, %r9 | 六个寄存器，当参数少于7个时， 参数从左到右放入寄存器: rdi, rsi, rdx, rcx, r8, r9；当参数为7个以上时，前 6 个与前面一样， 但后面的依次从 “右向左” 放入栈中，即和32位汇编一样。 |
二、寄存器详细内容
第二遍:汇编语言基础:寄存器和系统调用 - 简书寄存器 寄存器是处理器临时保存数据指令的的一部分。在x86_64架构中，寄存器能处理高达64位的数据。这意味着每个寄存器都可以保存该值没符号整数：0〜18,446,744,0...https://www.jianshu.com/p/d83b9da294d4 寄存器内容示意图：
三、通用寄存器列表
| 名称 | 简介 |
| EAX | (针对操作数和结果数据的)累加器 ，返回函数结果 |
| EBX | (DS段中的数据指针)基址寄存器。在内存寻址时存放基地址 |
| ECX | (字符串和循环操作数)计数器。时重复REP前缀指令和LOOP指令的内定计数器 |
| EDX | (I/O指针)数据寄存器 |
| EBP | (SS段中栈内数据指针)扩展基址指针寄存器 |
| ESP | (SS段中栈指针)栈指针寄存器 |
| ESI | (字符串操作源指针)源变址寄存器 |
| EDI | (字符串操作目标指针)目的变址寄存器 |
