A bit of a myth about compiled language code optimization
Recently, I’ve seen some people share their own experience of coding, such as the habit of changing the if statement to a ternary operator to reduce the number of lines of code. It is now customary to combine the same IF judgments together to reduce the number of if judgments and improve efficiency.
I thought so many years ago, but as I’ve gotten older, I think it doesn’t make much sense in compiled languages, and sometimes it even makes your code less readable.
example
There are two codes as follows:
#include <array>
#include <iostream>
int main(a)
{
std: :array<int, 122 >array{ 2700.2314.8429.7726.4817.8716.3598.6255.5056.8653.8571.5028.1259.3315.2896.1411.3847.879.7353.8056.8765.2344.6349.4156.8350.4164.4783.6800.8887.267.4478.6327.58.7961.756.5654.9546.5132.247.5514.7098.1156.795.2502.367.5330.2261.8692.2460.4823.8968.4976.1929.1051.9249.9713.2803.1743.3681.93.4967.2245.198.896.6372.4413.2615.6130.5766.5306.1236.888.8050.7080.3460.3473.1720.3913.3449.8420.1814.1261.1368.167.7938.4483.4843.4682.3301.4038.709.8655.598.3857.6285.2961.6817.1031.4007.1392.5717.5837.5695.9511.8891.7883.7035.2349.5752.3139.2442.3966.2007.9205.8434.5065.3795.6890.2715.1.5106.5083 };
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;
}

Copy the codeBecause the assembly is so long, we can just focus on the CMPL $1000, (%rax) line comparison, which appears twice in the first copy and once in the second, and the compiler perfectly translates the code. In production, however, we don’t release code like this, and O3 optimizations are common. So when we turn optimization on, the assembly code looks like this:

Copy the codeAt this point, we can still search CMPL $1001, %eax, in which case you will find two comparisons with 1001 in each assembly, and judging by the number of lines of assembly code generated, we can be bold enough to generate roughly the same result.
If this example isn’t obvious, look at the following code:
#include <iostream>
int main(a)
{
size_t sum = 0;
for (size_t i = 1; i <= 100; ++i)
{
sum += i;
}
std: :cout << sum << std: :endl;
return 0;
}

conclusion
The only conclusion can only be that the code you wrote is just a suggestion, how does the compiler implement it, how does it implement it, does it follow the code you wrote not what you said
So I don’t think it’s necessary to sacrifice readability for self-righteous optimizations. If your bitwise (+) operation is better than the normal (+) operation compiled directly by the compiler, you should hack the compiler, not the normal writing person.
