An input section description consists of a file name optionally followed by a list of section names in parentheses.The file name and the section name may be wildcard patterns, which we describe furt

Assign alias names to memory regions存储区域的别名分配Alias names can be added to existing memory regions created with the MEMORY command. Each name corresponds to at most one memory region别名可以被加

A couple of linker script commands deal with object file formats.处理对象文件格式的一对链接器脚本命令OUTPUT_FORMAT(bfdname)OUTPUT_FORMAT(default, big, little)------------------------------------------------

Linker scripts are text files.链接器脚本是一种文本文件You write a linker script as a series of commands. Each command is either a keyword, possibly followed by arguments, or an assignment to a symbol.

You may assign a value to a symbol in a linker script. This will define the symbol and place it into the symbol table with a global scope.你可以在链接脚本中给符号赋值. 这将定义这个符号并把它放入到一个全局性的符号表.Simple Ass

PROVIDEIn some cases, it is desirable for a linker script to define a symbol only if it is referenced and is not defined by any object included in the link. For example, traditional linkers defi

For ELF targeted ports, define a symbol that will be hidden and won't be exported. The syntax is HIDDEN(symbol = expression).对于ELF目标,定义的符号将会被隐藏而且不会被导出. 这种语法是HIDDEN ( symbol = expression )Here is

Source Code ReferenceAccessing a linker script defined variable from source code is not intuitive. In particular a linker script symbol is not equivalent to a variable declaration in a high le

The SECTIONS command tells the linker how to map input sections into output sections, and how to place the output sections in memory.SECTION命令用于告诉链接器如何去映射输入section到输出section,以及如何把输出section放置到内存中.

There are a few other linker scripts commands.一些的其它链接器脚本命令ASSERT(exp, message)------------------------------------------------------------Ensure that exp is non-zero. If it is zero, then

Several linker script commands deal with files.与文件处理相关的一些链接器脚本命令INCLUDE filename---------------------------------------------------------------Include the linker script filename at this po

The name of the output section is section. section must meet the constraints of your output format. In formats which only support a limited number of sections, such as a.out, the name must be one of

The address is an expression for the VMA (the virtual memory address) of the output section. This address is optional, but if it is provided then the output address will be set exactly as specified.

The most common output section command is an input section description.大部分公共的输出section命令用的是输入section的描述.The input section description is the most basic linker script operation. You use output

The full description of an output section looks like this:一个输出section的完全描述如下: section [address] [(type)] : [AT(lma)] [ALIGN(section_align) | ALIGN_WITH_INPUT] [SUBALIGN(

Many linker scripts are fairly simple.很多链接器脚本都有相应的简单.The simplest possible linker script has just one command: ‘SECTIONS’. You use the ‘SECTIONS’ command to describe the memory layout of the o

We need to define some basic concepts and vocabulary in order to describe the linker script language.为了描述链接器脚本语言,我们需要定义一些基本的概念和词汇.The linker combines input files into a single output file. The
