IAR
相比于 ARM 对于编译器的灵活安装，IAR 的编译器则只跟随其 IDE 发布，编译器不独立提供。IAR 安装后，目录就是下面这个样子了：

这里我们重点关注一下arm目录下的相关内容。其中内容有很多，这里主要介绍一下编译器相关的那些，首先看下图

我们可以手动提取其编译器，来作为命令行工具使用。但是对于 IAR 还是不建议这么用，个人感觉 IAR 在设计时，估计没考虑过让用户使用命令行模式来独立使用编译套件，因为其编译套件和其他好多东西都放在了一个目录中，不像ARM 将编译套件独立存放。但是，IAR 的编译套件是支持命令行使用的，在其介绍文档中有这么一句话：The compiler, assembler, and linker can also be run from a command line environment,if you want to use them as external tools in an already established project environment. 官方的介绍文档主要就是《 IAR C/C++ Development Guide Compiling and Linking》。

1. IAR 我用的比较少，主要内容来自于官方文档。管方文档更加详细，如有疑问直接去官方文档查看即可！官方文档目录为 IAR安装目录\arm\doc。具体如下：

《 IAR C/C++ Development Guide Compiling and Linking》，文档名为 EWARM_DevelopmentGuide.ENU.pdf
《IAR Assembler Reference Guide》，文档名为 EWARM_AssemblerReference.ENU.pdf
《C-STAT® Static Analysis Guide》，文档名为 EW_MisraC1998Reference.ENU.pdf; g9 K" |% n4 A, g, O7 `

2. 还可以直接从 IAR 的 IDE 的菜单进入：菜单 -> help

iasmarm.exe
这个是 IAR 的汇编语言的编译器。官方文档是这么介绍的：The IAR Assembler for Arm is a poweRFul relocating macro assembler with a versatile set of directives and expression operators. The assembler features a built-in C language preprocessor and supports conditional assembly. 大意就是： IAR Assembler for Arm是一个功能强大的重定位宏汇编程序，具有多种指令和表达式运算符。汇编程序具有内置的C语言预处理程序，并支持条件汇编。该工具官方有个独立的说明文档《IAR Assembler Reference Guide》，里面有该工具的详细使用说明。

IAR ILINK链接器（ilinkarm.exe）用于构建最终应用程序。通常，链接器需要以下信息作为输入:

几个目标文件，可能还有某些库
程序开始标签（默认设置）
链接器配置文件，用于描述目标系统内存中代码和数据的放置
u0 x6 |! p5 |& P, _7 d6 r

下图显示了链接过程：

IAR ILINK链接器生成ELF格式的绝对目标文件，其中包含可执行镜像。链接后，可以使用生成的绝对可执行映像

加载到IAR C-SPY调试器或任何其他兼容的外部调试器读取ELF和DWARF。
使用flash / PROM编程器对flash / PROM进行编程。在此之前可能必须使用ielftool将镜像中的实际字节转换为标准的Motorola 32-bit S-record 格式或Intel Hex-32格式。
: s/ `/ w& g# H1 Q

iarchive.exe
档案管理工具，类似于 ARM 的 armar 和 GCC 的 ar。用于创建和操作几个ELF目标文件的库（存档）。库文件包含多个可重定位的ELF对象模块，每个模块都可以由链接器独立使用。与直接指定给链接器的对象模块相比，只有在需要时才包含库中的每个模块。

IAR ELF Tool V10.4.14.1149 [BUILT at IAR]
Copyright 2007-2019 IAR Systems AB.
Usage: ielftool input_file output_file
Available command line options:
--bin Save as raw binary
--checksum sym:size,algo[:[1|2][a|m|z][r][R][o][x][i|p][W|L]][,start]
;range[;range...]
Generate checksum
sym Checksum symbol
size Length of the symbol in bytes
algo Algorithm: sum, sum8wide, sum32, crc16, crc32
crc64iso, crc64ecma or crc=poly
1|2 Complement: 1 or 2
a|m|z Reverse the bit order for:
input bytes only: a
input bytes and final checksum: m
final checksum only: z
o Output the Rocksoft model specification
r Reverse the byte order within each word
R Traverse the range(s) in reverse order
x Toggle the endianess of the checksum
i|p Use initial value normally: i
Prefix input data with the start value: p
W|L Use a checksum unit length of 2 bytes: W
Use a checksum unit length of 4 bytes: L
start Initial checksum value (defaults to 0)
range Do checksum of bytes in range
--fill [v;]pattern;range[;range...]
Specify fill
v Virtual fill, do not generate actual filler bytes.
This can be used for checksums and parities.
pattern Sequence of filler bytes
range Fill range
--front_headers Move program and section headers to the front of the ELF file.
--ihex Save as 32-bit linear Intel Extended hex
--offset [-]offset
Add (subtract if - is used) offset to all address records.
This only works for the output formats: Motorola S-records,
Intel Hex, Simple-Code and TI-TXT
--parity sym:size,algo:flashbase[:[r][[B|W|L]];range[;range...]
Generate parity bits
sym Parity symbol
size Length of the symbol in bytes
algo Parity algorithm: odd, even
flashbase Ignore bytes before this address
r Traverse the range(s) in reverse order
B Use a parity unit length of 1 byte
W Use a parity unit length of 2 bytes
L Use a parity unit length of 4 bytes
range Perform parity on bytes in this range
--self_reloc relocator[,jtc]
Create self-relocating image with relocator
jtc Number of jump table entries
--silent Silent operation
--simple Save as Simple-code
--simple-ne Save as Simple-code without entry record
--srec Save as Motorola S-records
--srec-len length
Restrict the length of S-records
--srec-s3only Restrict the type of S-records to S3 (and S7)
--strip Remove all section headers and non-program sections
--titxt Save as Texas Instruments TI-TXT
--verbose Print all performed operations
--version Output tool version

使用示例：

This example fills a memory range with 0xFF and then calculates a checksum on the same range:ielftool my_input.out my_output.out --fill 0xFF;0–0xFF --checksum __checksum:4,crc32;0–0xFF
8 ]; N% s; F: n

ielfdumparm.exe
针对 ARM ELF 格式的文件的 Dumper工具。类似于 GCC 的 objdump，用于创建ELF可重定位或可执行映像内容的文本表示。主要用于以下三个方面：

To produce a listing of the general properties of the input file and the ELF segments and ELF sections it contains. This is the default behavior when no command line options are used.生成输入文件的常规属性列表以及它包含的ELF段和ELF节。当没有使用命令行选项时，这是默认行为。
To also include a textual representation of the contents of each ELF section in the input file. To specify this behavior, use the command line option --all .还包括输入文件中每个ELF部分内容的文本表示。要指定此行为，请使用命令行选项–all。
To produce a textual representation of selected ELF sections from the input file. To specify this behavior, use the command line option --section 从输入文件生成所选ELF节的文本表示。要指定此行为，请使用命令行选项–section2 A; f) w( z' e# D4 }6 E9 a o9 q
