GCC, the GNU Compiler Collection
    
    The GNU Compiler Collection includes front ends for C, C++, Objective-C, Fortran, Ada,
     Go, and D, as well as libraries for these languages (libstdc++,...). GCC was originally
     written as the compiler for the GNU operating system. The GNU system was developed to
     be 100% free software, free in the sense that it respects the user's freedom.
    
    
    We strive to provide regular, high quality releases, which we want to work well on a
     variety of native and cross targets (including GNU/Linux), and encourage everyone to
     contribute changes or help testing GCC. Our sources are readily and freely available 
    via Git and weekly snapshots.

### [gcc编译][gcc] ###

一步到位编译：gcc hello.c -o hello
    预处理 -E (.i) 编译 -S (.s) 汇编-c (.o) 连接-o
    预处理
    gcc -E hello.c -o hello.i -E:仅执行编译预处理
    -o:将结果输出并指定输出文件的文件名
    编译为汇编代码
    gcc -S hello.c(.i) -o hello.s -S：将C代码转换为汇编代码
    汇编：
    gcc -c hello.c -o hello.o -c：仅执行编译操作，不进行连接操作
    连接：
    gcc hello.o -o hello
    -o:将结果输出并指定输出文件的文件名
    -O0、-O1、-O2、-O3:编译优化选项的四个级别，-O0 表示没有优化, -O1 为默认值，-O3 优化级别最高
    -g：只是编译器，在编译的时候，产生调试信息
