+
+程序设计语言
+============
+
+内核是用C语言 [c-language]_ 编写的。更准确地说，内核通常是用 ``gcc`` [gcc]_
+在 ``-std=gnu89`` [gcc-c-dialect-options]_ 下编译的：ISO C90的 GNU 方言（
+包括一些C99特性）
+
+这种方言包含对语言 [gnu-extensions]_ 的许多扩展，当然，它们许多都在内核中使用。
+
+对于一些体系结构，有一些使用 ``clang`` [clang]_ 和 ``icc`` [icc]_ 编译内核
+的支持，尽管在编写此文档时还没有完成，仍需要第三方补丁。
+
+属性
+----
+
+在整个内核中使用的一个常见扩展是属性（attributes） [gcc-attribute-syntax]_
+属性允许将实现定义的语义引入语言实体（如变量、函数或类型），而无需对语言进行
+重大的语法更改（例如添加新关键字） [n2049]_
+
+在某些情况下，属性是可选的（即不支持这些属性的编译器仍然应该生成正确的代码，
+即使其速度较慢或执行的编译时检查/诊断次数不够）
+
+内核定义了伪关键字（例如， ``pure`` ），而不是直接使用GNU属性语法（例如,
+``__attribute__((__pure__))`` ），以检测可以使用哪些关键字和/或缩短代码, 具体
+请参阅 ``include/linux/compiler_attributes.h``
