Building a Simple LLVM-Based Compiler: Lexer, Parser, SSA, Optimizer, JIT and Mutable Variables

The tutorial walks through building a complete LLVM‑based Kaleidoscope compiler—from a tokenizing lexer and recursive‑descent parser, through AST construction, LLVM IR generation with SSA and phi nodes, optimization passes, JIT execution, and mutable variable handling via stack allocation—providing full C++ source examples.
