拿什么__CC_ARM，__ICCARM__，__GNUC__，__TASKING__ [英] What means __CC_ARM, __ICCARM__, __GNUC__, __TASKING__

问题描述

我在STM32l151rct6a由STM的工作，我已经在这些宏定义跌跌撞撞

I am working on STM32l151rct6a by stm, I have stumbled upon these MACRO definition

__CC_ARM, __ICCARM__, __GNUC__, __TASKING__

任何人都知道他们是什么意思？

Anyone knows what they means?

推荐答案

这些是ARM处理器不同的编译器，可能是这些宏用来隐藏code，它由几个编译器的编译编译器相关的东西。

These are different compilers for ARM processors, probably these macros are used to hide compiler-dependent stuff in code that's compilable by several compilers.

• ICCARM - >的 IAR （也会有宏 __ __ IAR_SYSTEMS_ICC 被设置为编译器平台版本


• __ __ IMAGECRAFT - > iMAGEcraft C语言（也请参阅下面的克利福的意见 - 也有一个宏观 __ __ ICC_VERSION ，看到的 PDF文档）


• TASKING - > 任务处理


• __ CC_ARM - >的 ARM公司（的RealView）编译器


• __ __ GNUC - > GCC

• ICCARM --> IAR (there will also be a macro __IAR_SYSTEMS_ICC__ that is set to the compiler platform version
• __IMAGECRAFT__ --> Imagecraft C (also see Clifford's comments below - there's also a macro __ICC_VERSION__, see the pdf documentation)
• TASKING --> Tasking
• __CC_ARM --> ARM's (RealView) compiler
• __GNUC__ --> gcc
