最近经常看见一些人分享自己撸码的经验，比如曾经习惯把if语句改成三目运算符，以减少代码行数。现在习惯把相同的if判断合并在一起，以减少if判断的次数，提高效率。
多年以前笔者也是这样想的，但是随着年龄的增长，窃以为在编译型语言中，这样做的意义并不大，而且有时甚至可能会降低代码可读性。
例子
有如下两份代码：
#include
#include
int main()
{
std::array array{ 2700, 2314, 8429, 7726, 4817, 8716, 3598, 6255, 5056, 8653, 8571, 5028, 1259, 3315,
2896, 1411, 3847, 879, 7353, 8056, 8765, 2344, 6349, 4156, 8350, 4164, 4783, 6800,
8887, 267, 4478, 6327, 58, 7961, 756, 5654, 9546, 5132, 247, 5514, 7098, 1156,
795, 2502, 367, 5330, 2261, 8692, 2460, 4823, 8968, 4976, 1929, 1051, 9249, 9713,
2803, 1743, 3681, 93, 4967, 2245, 198, 896, 6372, 4413, 2615, 6130, 5766, 5306,

2007, 9205, 8434, 5065, 3795, 6890, 2715, 1, 5106, 5083 };
auto x = 5330;
for (const auto &element : array)
{
if (element > 1000)
{
std::cout << "";
}
}
for (const auto &element : array)
{
if (element > 1000)
{
if (element == x)
{
std::cout << "hello, world" << std::endl;
}
}
}
return 0;
}
#include
#include
int main()
{
std::array array{ 2700, 2314, 8429, 7726, 4817, 8716, 3598, 6255, 5056, 8653, 8571, 5028, 1259, 3315,

auto x = 5330;
for (const auto &element : array)
{
if (element > 1000)
{
std::cout << "";
if (element == x)
{
std::cout << "hello, world" << std::endl;
}
}
}
return 0;
}
从代码角度看第二份代码应该优于第一份代码。
使用LLVM生成两份代码的对应汇编如下：

由于汇编太长，我们可以只关注cmpl $1000, (%rax)这一行比较，在第一份中出现了两次与1000进行比较，而第二份中进行了一次，编译器完美直译了代码。然而在生产环境中我们是不和这样发布代码的，一般都会进行O3优化。所以当我们开启优化后，汇编代码如下：

此时，我们依然可以通过搜索cmpl $1001, %eax，此时你会发现在每份汇编中都有两处与1001的比较，而且通过生成的汇编代码的行数判断，其实我们可以大胆的出生成的结果基本一致。
如果这个例子还不是很明显，可以看下面的代码：
#include
int main()
{
size_t sum = 0;
for (size_t i = 1; i <= 100; ++i)
{
sum += i;
}
std::cout << sum << std::endl;
return 0;
}
O3优化后的关键代码：

这个5050是从何而来？
结论
唯一的结论只能是你写的代码只是一个建议，编译器怎么实现，如何实现，按不按照你写的代码编不是你说的
所以我认为没有必要牺牲代码的可读性而去做一些自以为是的优化，如果你用位运算实现的（+）运算比编译器直接将普通（+）运算编译的代码性能好的话，你应该去砍写编译器的人，而不是喷用正常写法的人菜。
