Gnu链接器-输出节类型

Question

据我所知，我读过链接器文档，有5种输出节类型：NOLOAD, DSECT, COPY, INFO, OVERLAY，但只解释了其中的2种: NOLOAD和OVERLAY。COPY，INFO和DSECT没有被解释，在互联网上到处都可以看到同样的2个解释，3个一言不发。有没有人愿意解释一下DSECT、COPY和INFO到底对output部分做了什么改变？

Answer 1

来自官方GNU ld文档(可以通过info ld很容易地找到)：

DSECT
COPY
INFO
OVERLAY
     These type names are supported for backward compatibility, and are
     rarely used.  They all have the same effect: the section should be
     marked as not allocatable, so that no memory is allocated for the
     section when the program is run
