项目描述

The GNU Compiler Collection contains frontends for C, C++, Objective-C, Fortran, Java, and Ada as well as libraries for these languages. It is a full-featured ANSI C compiler with support for K&R C as well. GCC provides many levels of source code error checking traditionally provided by other tools (such as lint), produces debugging information, and can perform many different optimizations to the resulting object code.

4.5.0

英特尔的Atom处理器的优化增加了，而对其他处理器支持增强。货币政策委员会的图书馆是综合性的更精确的编译时间运算评价。一个新的链接时增加了优化，以便为闭会期间的程序优化。许多优化得到了改善。现在的C编译器就立即退出缺少头文件。对于C + +0 x的改善实验性支持。一个实验性的C + +配置模式为补充。许多其他改动。
标签: Stable, Minor bugfixes, Major feature enhancements
Optimizations for Intel Atom processors were added, and the support for other processors was enhanced. The MPC library was integrated for more accurate compile time arithmetic evaluation. A new link-time optimizer was added, to allow for inter-procedural optimizations. Many optimizations were improved. The C compilers now exit immediately on a missing header file. The experimental support for C++0x was improved. An experimental C++ profile mode was added. Many other changes were made.
