Clang

Type Macro Format
Identification __clang__  
Version __clang_major__ Version
Version __clang_minor__ Revision
Version __clang_patchlevel__ Patch

Notice that clang also defines the GNU C version macros, but you should use the clang feature checking macros to detect the availability of various features.

The values of the __clang_major__, __clang_minor__, and __clang_patchlevel__ macros are not consistent across distributions of the Clang compiler. For example, the Clang 3.1 distribution available at http://clang.llvm.org defines__clang_major__ and __clang_minor__ as 3 and 1 respectively. The version of Clang distributed with Apple XCode 4.4 is branded as "Apple Clang 4.0" and derives from the open source Clang 3.1 distribution, but defines these macros with the values 4and 0 respectively. Apple's Clang distribution can be identified by the presence of the __apple_build_version__ macro.

Type Macro
Identification __FCC_VERSION

GCC C/C++

Type Macro Description
Identification __GNUC__  
Version __GNUC__ Version
Version __GNUC_MINOR__ Revision
Version __GNUC_PATCHLEVEL__ Patch (introduced in version 3.0)

Notice that the meaning of the __GNUC__ macro has changed subtly over the years, from identifying the GNU C/C++ compiler to identifying any compiler that implements the GNU compiler extensions (see the Feature request - a macro defined for GCCdiscussion for further information). For example, the Intel C++ on Linux also defines these macros from version 8.1 (see the Intel C++ Compiler 8.1 for Linux Release Notes and Intel Compilers for Linux: Compatibility with GNU Compilers.)

Example
GNU C/C++ __GNUC__ __GNUC_MINOR__ __GNUC_PATCHLEVEL__
2.7.x 2 7 N/A
3.0.2 3 0 2

Alternative Version

If you prefer a single version macro, you can define the following yourself.

#if defined(__GNUC__)
# if defined(__GNUC_PATCHLEVEL__)
#  define __GNUC_VERSION__ (__GNUC__ * 10000 \
                            + __GNUC_MINOR__ * 100 \
                            + __GNUC_PATCHLEVEL__)
# else
#  define __GNUC_VERSION__ (__GNUC__ * 10000 \
                            + __GNUC_MINOR__ * 100)
# endif
#endif

The format of this new macro is:

Type Macro Format Description
Version __GNUC_VERSION__ VVRRPP VV = Version
RR = Revision
PP = Patch
Example of Alternative Version
GNU C/C++ __GNUC_VERSION__
2.7.x 20700

Notice that the z/OS C/C++ compiler also defines __IBMC__ and __IBMCPP__ macros, but with a different syntax. See the entry on the z/OS C/C++ compiler below for further information.

Example
IBM XL C/C++ __xlC__ __xlC_ver__
3.1 0x0301  
4.5 0x0405  
5.0 0x0500  
12.01.0000.0004 0x0C01 0x00000004

IBM z/OS C/C++

This is the XL C/C++ compiler for mainframes (e.g. z/OS). The entry on XL C/C++ has been split into two for clarity.

Type Macro Format Description

RR = Revision
P = Patch

Defined for z/OS XL C/C++
Version __COMPILER_VER__ 0xNVRRPPPP N = Product (see above)
V = Version
RR = Revision
PPPP = Patch

Defined for z/OS XL C/C++

Notice that XL C/C++ also defines __IBMC__ and __IBMCPP__ macros, but with a different syntax. You can use __xlC__ (only defined for XL C/C++) or __COMPILER_VER__ (only defined for z/OS C/C++) to distinguish between the two. Alternatively, the macro identifying z/OS (__MVS__) can be used to distinguish between them.

#if defined(__IBMC__) || defined(__IBMCPP__)
# if defined(__COMPILER_VER__)
/* z/OS C/C++ so __IBMC__ is defined as NVRRM */
# else
/* XL C/C++ so __IBMC__ is defined as VRP */
# endif
#endif
Example
IBM z/OS XL C/C++ __IBMC__ __COMPILER_VER__

MinGW and MinGW-w64

MinGW (formerly known as MinGW32) is a toolchain for creating 32 Bit Windows executables. The MinGW-w64 projects offers toolchains for creating 32 Bit and 64 Bit Windows executables. The following table shows which macros are defined by each toolchain:

Type Macro Description MinGW32 MinGW-w64 32 Bit MinGW-w64 64 Bit
Identification __MINGW32__   defined defined defined
Version __MINGW32_MAJOR_VERSION Version defined defined defined
Version __MINGW32_MINOR_VERSION Revision defined defined defined
Identification __MINGW64__   - - defined
Version __MINGW64_VERSION_MAJOR Version - defined defined
Version __MINGW64_VERSION_MINOR Revision - defined defined

Notice that __MINGW32_MAJOR_VERSION, __MINGW32_MINOR_VERSION, __MINGW64_VERSION_MAJOR, and__MINGW64_VERSION_MINOR
are only defined if appropriate headers are included. Appropriate headers are 
<stdlib.h>, <stdio.h>, <windows.h>, <windef.h>, and probably more.

Examples
__MINGW32_MAJOR_VERSION __MINGW32_MINOR_VERSION __MINGW64_VERSION_MAJOR __MINGW64_VERSION_MINOR Description

Norcroft C

Type Macro Format Description
Identification __CC_NORCROFT    
Version __ARMCC_VERSION V.R V = Version
R = Revision

Notice that __ARMCC_VERSION is assigned a floating-point number, so it cannot be used by the preprocessor to compare versions.

Example
Norcroft C __ARMCC_VERSION
4.69 4.69
4.90 4.90

Version __OPENCC_PATCHLEVEL__ P.B P = Patch
B = Build

Notice that __OPENCC_PATCHLEVEL__ can be a floating-point number (e.g. 5.2 for Open64 version 4.2.5.2) so it cannot be used by the preprocessor to compare patch-levels.

标识符分为关键字、预定义标识符和用户自定义标识符。关键字是编程语言中保留的标识符，例如int、if等；预定义标识符由系统定义，用户不可修改；用户标识符则是程序员自定义的标识符，如变量名或函数名。 常量是在...

预定义标识符如define、scanf、printf等有特殊用途，它们可以作为用户自定义标识符。算术表达式和赋值表达式是程序中常见的表达方式，算术表达式包括加、减、乘、除和取余运算，而赋值表达式则涉及变量的赋值操作。...

预定义标识符如define、scanf和printf等，是C语言中已经定义好的关键字，不能用作自定义标识符。 在C语言中，整数与实数的表示与运算也是基础知识点。C语言支持八进制、十进制和十六进制的整数表示，但在内部处理时...

预定义标记符如define、scanf、printf等是编译器提供的，而用户定义标记符由程序员自定义。 在C语言中，进制转换是基础知识点之一，需要掌握十进制与二进制、八进制、十六进制之间的转换规则。整数与实数部分，...

 ARM编译器预定义了一些宏，这些预定义宏对应一定的数值，有些预定义宏没有对应数值，见下表：_arm                 _                使用编译器armcc,tcc,armcpp,tcpp时_ARMCC_VERSION       Ver              代表编译器版本号，其格式为：

编译器预定义 https://developer.arm.com/docs/dui0774/g/other-compiler-specific-features/predefined-macros 但有些代码使用了类似 #if defined (__GNUC__) 来适应不同的编译器，而 Arm Compiler 6 是定义了 __GNUC__ 的，可能会造成错误的代码被编译。 可以参考 CMSI...
从AC5到AC6转型之路（1）——补救和准备

【说在前面的话】时间大约在2015年，Arm第一次在 MDK 5.20 中引入了Arm Compiler 6（那时候的版本是 6.9），正式拉开了Arm官方编译器从第五版（armcc）到第六版（armclang）升级替换的序幕……嵌入式行业的长尾效应是及其突出的，且不说都2022年了还有很多人在坚持 MDK4，即便是从“Arm在2017年对外宣布停止维护 Arm Compiler 5”算起，如今5年过去了，坚持使用 armcc 的用户仍然不在少数。Arm Compiler 5，也就是大家口中的 armcc，

升级 MDK 5.37 后的问题处理: AC6编译选项, printf, 重启失效等

MDK ARM 5.28 之后包括 5.37 的版本. 这些版本即使勾选 Reset And Run, 在烧录后也不会自动重启执行 需要做以下设置 Debug -> ST-Link Debugger -> Settings 切换到 Pack 标签页, 取消勾选 Enable 点击 OK 保存. 不能再通过`__GNUC__`判断是否为 gnu arm gcc toolchain, 因为 Arm Compiler 6 默认定义了 `__GNUC__` , 如果用这个做宏判断, 会造成错误的代码被编译....
