Debuggers: A Deep Dive into the Architecture of a Software Debugging Tool

This is the first in a series of posts on debugger architecture. The author, drawing on years of experience building debuggers, explores the core principles and importance of this often-overlooked tool. More than just a tool for fixing bugs, a debugger provides deep insights into program execution and allows for verification of code correctness. The post details how debuggers work, including kernel interaction, CPU debugging features, breakpoint implementation, and stepping through code. Future posts will explore more advanced topics and the direction of debugger development.
