导致优化后结果不一样，这就是 编译器放弃优化的原因。 ## 告诉编译器别怕指针别名：___ restrict 关键字 void func(int *__restrict a, int *__restrict b, int *__restrict c) { *c = *a; *c = *b; } __restrict 是一个提示性的关键字，是程序员向编译器保证：这些指针之间不会发生重叠！从而他可以放心地优化成功： *b_5(D), *c_4(D) # main.cpp:4: } ret .cfi_endproc ## __restrict 关键字：只需加在非 const 的即可 void func(int const *a, int const *b, int *__restrict c) 实际上，___ restrict 只需要加在所有具有写入访问的指针（这里是 c）上，就可以优化成功。而我们可以用 const 禁止写入访问。 volatile *a 2. int * restrict a • 语法上区别：volatile 在 * 前面而 ___ restrict 在 * 后面。 功能上区别：volatile 是禁用优化，___ restrict 是帮助优化。 • 是否属于标准上区别： • volatile 和 const 一样是 C++ 标准的一部分。 • restrict 是 C99 标准关键字，但不是 C++
