对于x86-64 架构,有16个64位通用寄存器,各寄存器的相关信息如下表所示: 这里有一个Caller Save和Callee Save的概念,意思是寄存器由调用者保存还是被调用者保存,从上面表中可以看出,%rbx, %rbp, and %r12-r15是Callee Save registers。从早期的x86到现在,体系结构从8位扩展到16位、32位、64位,现在每个寄存器的...
x86-64架构包括16个64位通用寄存器，如%rbx、%rbp、%r12-%r15等。这些寄存器有调用者保存和被调用者保存的概念。早期的x86架构扩展到16位、32位、64位，每个寄存器内部结构具有多用途。例如，%rax的低8位是8位寄存器%al，相邻8位是%ah，低16位是%ax，以此类推。除了通用寄存器，还有名为SSE的扩展...

老迷说他喜欢保持字符串本身的类型，进行字符串的匹配比较，而不喜欢把字符串强制转换为数字进行比较。
Unfortunately i was busy last time and there were not new post, so today I continue to write posts about assembly, and will try to do it every week. 今天我们要看字符串和一些字符串操作。我们仍然使用NASM汇编和Linux X86_64。 Today we will look at strings and some strings operations. We ...
