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...

X86-64 IntroductionThe X86-64 assembly language was created by AMD and then adopted by Intel. The X86-64 assembly language extends the x86 32 bit architecture to 64 bits. X86-64 is a superset ofx86-32. It provides an incremental evolution to migrate from x86-32 bits to x86-64 bits and...
In the new asm32.asm file remove its default contents and fill it in with the x86 Assembly language instructions. I will duplicate the functionality of the x64 code: x86[Copy] .686p .model flat, C .data msgCaption db "Message box text",0 .code ALIGN 8 EXTERN _imp__MessageBoxA...
Gentle Introduction to x86-64 Assembly Introduction This document is meant to summarise differences between x86-64 and i386 assembly assuming that you already know well the i386 gas syntax. I will try to keep this document up to date until official documentation is available. ...

x86 IA-32 and x86-64 userland minimal examples tutorial. Hundreds of runnable asserts. Nice GDB setup. IO done with libc, so OS portable in theory. NASM and GAS covered. Tested in Ubuntu 18.04. Containers (ELF), linking, calling conventions. System land
Linux has a completely different system call ABI under 64bit mode. The syscalls have different numbers and are called in a completely different way. Depending on how your kernel was compiled though, the 32bit interface may be present and usable as well lkml. In ignorance of this situation, ...
