Compiler perform optimization

Does Go compiler optimize?
When you build a Go binary, the Go compiler performs optimizations to try to generate the best performing binary it can.
For example, constant propagation can evaluate constant expressions at compile time, avoiding runtime evaluation cost..
How do you optimize a code?
How to Optimize Your Code
1. Use the right data types.
2. Keep your code as simple as possible
3. Avoid unnecessary computations
4. Cache frequently used data
5. Avoid unnecessary I/O
6. Use the most efficient algorithms
How do you optimize performance code?
In general, though, there are a few basic principles you can follow to optimize your code:
1. Use the right data types.
2. Keep your code as simple as possible
3. Avoid unnecessary computations
4. Cache frequently used data
5. Avoid unnecessary I/O
6. Use the most efficient algorithms
When should optimization be performed?
Optimization can reduce readability and add code that is used only to improve the performance.
This may complicate programs or systems, making them harder to maintain and debug.
As a result, optimization or performance tuning is often performed at the end of the development stage..

A large variety of optimizations are provided by GCC.
Most are categorized into one of three levels, but some are provided at multiple levels.
Some optimizations reduce the size of the resulting machine code, while others try to create code that is faster, potentially increasing its size.
Optimization can also be done by the programmer manually, by making changes to the source code to make it run faster.
In summary, compiling is the process of translating C source code into machine code, while optimizing is the process of making the compiled code run faster or use less memory.

In computing, an optimizing compiler is a compiler that tries to minimize or maximize some attributes of an executable computer program. Common requirements are to minimize a program's execution time, memory footprint, storage size, and power consumption (the last three being popular for portable computers).

The C/C++ compiler compiles each source file separately and produces the corresponding object file. This means the compiler can only apply optimizations on a single source file rather than on the whole program. However, some important optimizations can be performed only by looking at the whole program.

How do I control optimizations for specific functions?

In addition to the compiler switches /O1, /O2 and /Ox, you can control optimizations for specific functions using the optimize pragma, which looks like this:

The optimization list can be either empty or contain one or more of the following values:

t and y.
These correspond to the compiler switches /Og, /Os, /Ot and /Oy, respectively.
