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》。 5 M& z3 q7 F0 R s- _, U% _$ ]% ~# Q! y7 \% S9 H3 W* a

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。 - d0 S/ X* I9 u$ f/ z7 q, F0 X.
