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 5.1 发布，此版本包括大量新特性及 Bug 修复：
一般优化改进：
Inter-procedural optimization improvements
Link-time optimization improvements
Feedback directed optimization improvements
Register allocation improvements
UndefinedBehaviorSanitizer gained a few new sanitization options
Pointer Bounds Checker, a bounds violation detector, has been added and can be enabled via -fcheck-pointer-bounds. Memory accesses are instrumented with run-time checks of used pointers against their bounds to detect pointer bounds violations (overflows). The Pointer Bounds Checker is available on x86/x86-64 GNU/Linux targets with a new ISA extension Intel MPX support. See the Pointer Bounds Checker Wiki page for more details.
新语言及语言具体改进：
OpenMP 4.0 specification offloading features are now supported by the C, C++, and Fortran compilers. Generic changes:
Infrastructure (suitable for any vendor).
Testsuite which covers offloading from the OpenMP 4.0 Examples document.
Specific for upcoming Intel Xeon Phi products:
Run-time library.
Card emulator.
GCC 5 includes a preliminary implementation of the OpenACC 2.0a specification. OpenACC is intended for programming accelerator devices such as GPUs. See the OpenACC wiki page for more information.

GCC 原名为 GNU C 语言编译器（GNU C Compiler），因为它原本只能处理 C语言。GCC 很快地扩展，变得可处理 C++。之后也变得可处理 Fortran、Pascal、Objective-C、Java, 以及 Ada 与其他语言。
