求助g++编译参数
有一个arm的elf执行文件，使用readelf查看只有text和bss段，不知道是用什么参数编译出来的呢？我尝试用-s -O3 -static参数编译一个程序，但有很多段。

$arm-none-linux-gnueabi-readelf -a test_elf

使用file查看
$file test_elf

------解决方案--------------------
一些人想学习一个elf文件格式，自己写的吧
------解决方案--------------------
gcc可以合并段，具体参数忘了

VC的还记得
------解决方案--------------------
得写ld链接脚本
具体怎么写网上可查.
