1. 需要一些基础库文件

% ls env
asm_io.inc  asm_io.o  cdecl.h  driver.c

2. 汇编模板文件：

%include "asm_io.inc"


segment .data

segment .text
    global asm_main
asm_main:
    enter 0, 0
    pusha

    popa
    mov eax,0
    leave
    ret

3. 自己写的一键执行汇编文件的shell程序：

% cat /root/bin/exasm
if [ $# -eq 1 ]; then
    nasm -o "$1.m.o" -f elf "$1"
    gcc -m32 -o "$1.m" driver.c asm_io.o "$1.m.o"
    ./"$1.m"

    mv $1.m* ~/trash/
fi

if [ $# -eq 2 ]; then
    nasm -o "$1.m.o" -f elf "$1"
    gcc -g -m32 -o "$1.m" "$2" asm_io.o "$1.m.o"
    ./"$1.m"

    #mv "$1.m" ~/trash
    #mv "$1.m.o" ~/trash/
fi

4. 一般是这样运行汇编的：

% ls
asm_io.inc  asm_io.o  cdecl.h  driver.c  env  lab1.asm  m_temp.asm
% exasm lab1.asm

5. debug汇编程序

5.1 生成反汇编文件，

% cat /root/bin/asm_gen_out
if [ $# -eq 1 ]; then
    nasm -o "$1.m.o" -f elf "$1"
    gcc -g -m32 -o "$1.m" driver.c asm_io.o "$1.m.o"
    objdump -S "$1.m" > "$1.m.dis_asm"
fi
% asm_gen_out lab1.asm
% ls
asm_io.asm  asm_io.o  driver.c  lab1.asm.m          lab1.asm.m.o
asm_io.inc  cdecl.h   lab1.asm  lab1.asm.m.dis_asm  m_temp.asm

接着可以打开xxx.m.dis_asm看反汇编文件，可以看到指令的地址。可以通过vim搜索asm_main函数。

5.2 gdb调试汇编程序

% cat /root/bin/asm_debug
if [ $# -eq 1 ]; then
    nasm -o "$1.m.o" -f elf "$1"
    gcc -g -m32 -o "$1.m" driver.c asm_io.o "$1.m.o"
    gdb "$1.m"

fi
% asm_debug lab1.asm
