GCC GNU编译器套装

GCC（GNU Compiler Collection，GNU编译器套装）是一套由GNU工程开发的支持多种编程语言的编译器。GCC是自由软件发展过程中的著名例子，由自由软件基金会以GPL协议发布。GCC是大多数类Unix操作系统（如Linux、BSD、Mac OS X等）的标准的编译器，GCC同样适用于微软的Windows。

GCC 6.1 发布了，该版本较之前GCC5 新怎了大量的功能特性，默认采用C++14为新的标准，替代了之前的C++98。OpenMP 4.5规范将在本版本中被支持。此外，GCC 6.1 增强了对 C++17 的试验性支持；大大改进了诊断特性，包括位置，位置范围，拼写错误标识符建议，选项名字等等改进；新增了修复提示和一些警告提示。改进记录如下：

• UndefinedBehaviorSanitizer gained a new sanitization option, -fsanitize=bounds-strict, which enables strict checking of array bounds.  In particular, it enables -fsanitize=bounds as well as instrumentation of flexible array member-like arrays.

• Type-based alias analysis now disambiguates accesses to different pointers. This improves precision of the alias oracle by about 20-30% on higher-level C++ programs. Programs doing invalid type punning of pointer types may now need -fno-strict-aliasing to work correctly.

• Alias analysis now correctly supports weakref and alias attributes. This makes it possible to access both a variable and its alias in one translation unit which is common with link-time optimization.

• Value range propagation now assumes that the this pointer of C++ member functions is non-null.  This eliminates common null pointer checks but also breaks some non-conforming code-bases (such as Qt-5, Chromium, KDevelop). As a temporary work-around -fno-delete-null-pointer-checks can be used. Wrong code can be identified by using -fsanitize=undefined.
