GCC 5.1 發布，C/C++ 編譯器

GCC 5.1 發布，此版本包括大量新特性及 Bug 修復：

一般優化改進：

• 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.

新語言及語言具體改進：

• 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（GNU Compiler Collection，GNU編譯器套裝），是一套由 GNU 開發的編程語言編譯器。它是一套以 GPL 及 LGPL 許可證所發行的自由軟件，也是 GNU計劃 的關鍵部分，亦是自由的 類Unix 及蘋果計算機 Mac OS X 操作系統的標準編譯器。GCC（特別是其中的C語言編譯器）也常被認為是跨平臺編譯器的事實標準。

GCC 原名為 GNU C 語言編譯器（GNU C Compiler），因為它原本只能處理 C語言。GCC 很快地擴展，變得可處理 C++。之后也變得可處理 Fortran、Pascal、Objective-C、Java, 以及 Ada 與其他語言。
