每个PUSH指令是否在x64上推送8个字节的倍数？ 2个答案

什么是AMD64系统上的pushl %ecx和pushl %ecx的pushl %ecx ，我的结果是Error: invalid instruction suffix for 'push'我看了一下，有人建议将ecx更改为rcx但这只会导致Incorrect register '%rcx' used with 'l' suffix

谢谢你的帮助。

最满意答案

在AMD64上， push和pop操作隐式为64位，没有32位对应项。 尝试：

pushq %rcx popq %rcx

详情请见此处 。

On AMD64, push and pop operations are implicitly 64-bits and have no 32-bit counterparts. Try:

pushq %rcx popq %rcx
