BCFS: Building Compiler From Scratch

An educational compiler built from scratch in C++.

This project adopts the bottom-up approach, starting from the ELF object file and ARM64 assembly, then working our way up to the source language.

[1] print hello world

cd ch1.1

Build & Run

make

This will:

1. Compile to gen from main_hello.cpp and obj_writer.cpp
2. Run ./gen to generate hello.o
