How the Go Compiler REALLY Works: IR Generation & Inlining Explained

Описание: Ever wondered what actually happens inside the Go compiler after type checking?
In this video, we break down one of the most important yet misunderstood stages of the Go compiler:

👉 IR Generation (High-Level IR)
👉 Inlining (Function Body Substitution)

You’ll learn:

Why Go converts your code from AST to IR

How IR makes optimizations possible

What function inlining really is (no runtime magic!)

Why inlining makes code faster but binaries larger

When the Go compiler decides NOT to inline

How duplicated machine code affects binary size & instruction cache

Interview-ready mental models with real Go examples

This video is perfect for:

Go developers

Backend engineers

Compiler learners

FAANG / system-design interview prep

Anyone curious about how Go turns code into machine instructions
