[笔记] Intel C++编译器的预定义宏（Windows版、Linux版）

　　网上有很多介绍VC与GCC预定义宏的帖子，例如《C\C＋＋宏大全》。

　　而对于Intel C++编译器的预定义宏，似乎没人介绍。
　　我Google了很久，发现Intel官网上有，但是很奇怪，很多链接都失效了，报告404错误。反复调整搜索关键字，一个一个的尝试链接，最后终于找到了有效的页面了。为了怕以后链接失效，赶紧记录下载。

　　该手册的名字是《Intel® C++ Compiler XE 12.1 User and Reference Guides》，分别有Windows版和Linux版——
Windows：http://software.intel.com/sites/products/documentation/hpc/composerxe/en-us/2011Update/cpp/win/index.htm
Linux：http://software.intel.com/sites/products/documentation/hpc/composerxe/en-us/2011Update/cpp/lin/index.htm

一、Windows版

1.1 ANSI Standard Predefined Macros（ANSI标准预定义宏）

http://software.intel.com/sites/products/documentation/hpc/composerxe/en-us/2011Update/cpp/win/bldaps_cls/common/bldaps_ansi_macros.htm

The ANSI/ISO standard for the C language requires that certain predefined macros be supplied with conforming compilers. The following table lists the macros that the Intel® C++ Compiler supplies in accordance with this standard:

The compiler includes predefined macros in addition to those required by the standard. The default predefined macros differ among Windows*, Linux*, and Mac OS* X operating systems due to the default /Za compiler option on Windows. Differences also exist on Linux OS and Mac OS X as a result of the -std compiler option.

Macro	Value
__DATE__	The date of compilation as a string literal in the formMmm dd yyyy.
__FILE__	A string literal representing the name of the file being compiled.
__LINE__	The current line number as a decimal constant.
__STDC__	The name __STDC__ is defined when compiling a C translation unit.
__STDC_HOSTED__	1
__TIME__	The time of compilation as a string literal in the formhh:mm:ss.

1.2 Additional Predefined Macros（额外的预定义宏）

The Intel® C++ Compiler supports the predefined macros listed in the table below. The compiler also includes predefined macros specified by the ISO/ANSI standard.

The following table lists the predefined macros on systems based on either the IA-32 or Intel® 64 architecture.

These labels apply:

• i32 means that the macro is included on systems based on IA-32 architecture.

• i64em means that the macro is included on systems based on Intel® 64 architecture.
