objdump 介绍
objdump命令是用查看目标文件或者可执行的目标文件的构成的gcc工具
objdump 选项介绍
--archive-headers -a 显示档案库的成员信息,类似ls -l将lib*.a的信息列出。 -b bfdname --target=bfdname 指定目标码格式。这不是必须的,objdump能自动识别许多格式,比如: objdump -b oasys -m vax -h fu.o 显示fu.o的头部摘要信息,明确指出该文件是Vax系统下用Oasys编译器生成的目标文件。objdump -i将给出这里可以指定的目标码格式列表。 -C --demangle 将底层的符号名解码成用户级名字,除了去掉所开头的下划线之外,还使得C++函数名以可理解的方式显示出来。 --debugging -g 显示调试信息。企图解析保存在文件中的调试信息并以C语言的语法显示出来。仅仅支持某些类型的调试信息。有些其他的格式被readelf -w支持。 -e --debugging-tags 类似-g选项,但是生成的信息是和ctags工具相兼容的格式。 --disassemble -d 从objfile中反汇编那些特定指令机器码的section。 -D --disassemble-all 与 -d 类似,但反汇编所有section. --prefix-addresses 反汇编的时候,显示每一行的完整地址。这是一种比较老的反汇编格式。 -EB -EL --endian={big|little} 指定目标文件的小端。这个项将影响反汇编出来的指令。在反汇编的文件没描述小端信息的时候用。例如S-records. -f --file-headers 显示objfile中每个文件的整体头部摘要信息。 -h --section-headers --headers 显示目标文件各个section的头部摘要信息。 -H --help 简短的帮助信息。 -i --info 显示对于 -b 或者 -m 选项可用的架构和目标格式列表。 -j name --section=name 仅仅显示指定名称为name的section的信息 -l --line-numbers 用文件名和行号标注相应的目标代码,仅仅和-d、-D或者-r一起使用使用-ld和使用-d的区别不是很大,在源码级调试的时候有用,要求编译时使用了-g之类的调试编译选项。 -m machine --architecture=machine 指定反汇编目标文件时使用的架构,当待反汇编文件本身没描述架构信息的时候(比如S-records),这个选项很有用。可以用-i选项列出这里能够指定的架构. --reloc -r 显示文件的重定位入口。如果和-d或者-D一起使用,重定位部分以反汇编后的格式显示出来。 --dynamic-reloc -R 显示文件的动态重定位入口,仅仅对于动态目标文件意义,比如某些共享库。 -s --full-contents 显示指定section的完整内容。默认所有的非空section都会被显示。 -S --source 尽可能反汇编出源代码,尤其当编译的时候指定了-g这种调试参数时,效果比较明显。隐含了-d参数。 --show-raw-insn 反汇编的时候,显示每条汇编指令对应的机器码,如不指定--prefix-addresses,这将是缺省选项。 --no-show-raw-insn 反汇编时,不显示汇编指令的机器码,如不指定--prefix-addresses,这将是缺省选项。 --start-address=address 从指定地址开始显示数据,该选项影响-d、-r和-s选项的输出。 --stop-address=address 显示数据直到指定地址为止,该项影响-d、-r和-s选项的输出。 -t --syms 显示文件的符号表入口。类似于nm -s提供的信息 -T --dynamic-syms 显示文件的动态符号表入口,仅仅对动态目标文件意义,比如某些共享库。它显示的信息类似于 nm -D|--dynamic 显示的信息。 -V --version 版本信息 --all-headers -x 显示所可用的头信息,包括符号表、重定位入口。-x 等价于-a -f -h -r -t 同时指定。 -z --disassemble-zeroes 一般反汇编输出将省略大块的零,该选项使得这些零块也被反汇编。 @file 可以将选项集中到一个文件中,然后使用这个@file选项载入。
实例
首先,在给出后面大部分测试所基于的源代码以及编译指令。 源代码如下:
1 #include <stdio.h> 2 #include <stdlib.h> 3 int test_pass_parm(int a, int b, int c, int d, int e, int f, int g, int h) 4 { 5 6 printf("a:%0x, b:%0x c:%0x d:%0x e:%0x f:%0x g;%0x h:%0x\n", a,b,c,d,e,f,g,g); 7 return 0; 8 } 9 int main(int argc, char **argv) 10 { 11 int a = 1, b= 2, c=3, d = 4, e =5, f=6, g= 7, h =8; 12 test_pass_parm(a,b,c,d,e,f,g,h); 13 return 0; 14 }
对以上源代码进行编译生成可执行程序 *** pass_para ***
,如下:
[root@localhost test]# gcc -g pass_parm.c -o pass_parm
