如何将2个部分放在1个段中(使用ld脚本) [英] How to put 2 sections in 1 segment (Using ld scripts)

问题描述

我有以下链接描述文件:

I have the following linker script:

SECTIONS {

    .arora_exec_free_space 4399531 : 
    {
        *(.text)
        *(.rodata)
        *(.data.rel.ro.local)
    }
    .arora_data_free_space (ADDR(.arora_exec_free_space) + SIZEOF(.arora_exec_free_space)) : AT (7592352)
    {
        *(.data)
        *(.bss)
        *(.got)
    }
}

编译程序时，两个部分(exec和data)位于不同的LOAD段中.我想将两个部分(.arora_data_free_space和.arora_exec_free_space)合而为一LOAD段.有什么方法可以使用链接描述文件吗?我该怎么做?谢谢.

When I compile my program the two section (exec and data) are in different LOAD segments. I want to put the two sections (.arora_data_free_space and .arora_exec_free_space) into one LOAD segment. Is there any way to do it using linker scripts? How can I do it? Thanks.

推荐答案

当然-您只需要使用

Sure - you just need to use PHDRS. The example at that link is pretty much exactly what you want to do, I think. Here is an (untested) example I made from your linker script:

PHDRS
{
   mysegment PT_LOAD;
}

SECTIONS 
{
    .arora_exec_free_space 4399531 : 
    {
        *(.text)
        *(.rodata)
        *(.data.rel.ro.local)
    } :mysegment

    .arora_data_free_space (ADDR(.arora_exec_free_space) + SIZEOF(.arora_exec_free_space)) : AT (7592352)
    {
        *(.data)
        *(.bss)
        *(.got)
    } :mysegment
}
