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

一、Windows版
1.1 ANSI Standard Predefined Macros（ANSI标准预定义宏）
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.
