DONE Episode 1 - Introduction

What is it all about?

• Create a programming lang
• Guide for contributors
• A LLVM/MLIR guide

The Plan

• Git branches
• No live coding
• Feel free to contribute

Serene and a bit of history

• Other Implementations

• Requirements

  • C++ 14
  • CMake
• Repository: https://devheroes.codes/Serene

Serene

A Compiler frontend

Steps

• serenec in parses the command lines args
• reader reads the input file and generates an AST
• semantic analyzer walks the AST aned generates a new AST and rewrites the necessary nodes.
• slir generator generates slir dialect code from AST.
• We lower slir to other dialects of the MLIR which we call the result mlir.
• Then, We lower everything to the LLVMIR dialect and call it lir (lowered IR).
• Finally we fully lower lir to LLVM IR and pass it to the object generator to generate object files.
• Call the default c compiler to link the object files and generate the machine code.
