Kompilointiprosessi, also known as compilation process, is a series of steps that a compiler takes to convert source code written in a high-level programming language into machine code or an intermediate representation that can be executed by a computer. The process typically involves several phases, including lexical analysis, syntax analysis, semantic analysis, optimization, and code generation.

Lexical analysis, or scanning, involves breaking down the source code into tokens, which are the smallest units of meaning in the language. Syntax analysis, or parsing, involves analyzing the structure of the tokens to ensure they conform to the language's grammar rules. Semantic analysis involves checking the meaning of the code to ensure it makes sense in the context of the language's rules and the program's logic.

Optimization involves improving the efficiency of the code by rearranging or simplifying it without changing its meaning. This can involve techniques such as loop unrolling, inlining, and constant propagation. Code generation involves translating the optimized intermediate representation into machine code or an intermediate representation that can be executed by the target machine.

The output of the compilation process is typically an executable file or an intermediate representation that can be executed by a virtual machine or interpreter. The compilation process can be performed at compile time, link time, or run time, depending on the language and the compiler's design.
