This document discusses the different stages of the compiler process. It involves breaking source code down through lexical analysis, syntax analysis, semantic analysis, code generation, and optimization to produce efficient machine-readable target code. Key steps include preprocessing, compiling, assembling, linking, and loading to translate human-readable source code into an executable program.
