ARM交叉编译工具链
- GNU（提供源码，自行编译制作）
- Codesourcery
- Linora (提供源码，和已经编译好的release binrary)
两者主要区别是，ABI是运行在x86,x64平台， EABI是嵌入式平台上（如ARM，MIPS，android, iOS等）。
命名规则
对应分别是 :
arch [-vendor] [-os] [-(gnu)eabi]

Pre-built GNU toolchain for Arm Cortex-M and Cortex-R processors
The GNU Arm Embedded toolchains are integrated and validated packages featuring the Arm Embedded GCC compiler, libraries and other GNU tools necessary for bare-metal software development on devices based on the Arm Cortex-M and Cortex-R processors. The toolchains are available for cross-compilation on Microsoft Windows, Linux and Mac OS X host operating systems.
These toolchains are based on Free Software Foundation's (FSF) GNU Open source tools and newlib.
These toolchains support Arm Cortex-M0, Cortex-M0+, Cortex-M3, Cortex-M4, Cortex-M7, Cortex-M23, Cortex-M33, Cortex-R4, Cortex-R5, Cortex-R7, Cortex-R8 and Cortex-R52 processors.
The toolchains support code generation for non-OS or 'bare-metal' environments. These toolchains are based on Free Software Foundation's (FSF) GNU Open source tools and newlib.
