Onramp Compiler Successfully Compiles DOOM from Scratch
2024-12-31
After two years of development, a programmer has successfully compiled the classic game DOOM using a self-bootstrapping compiler called Onramp. Starting from a simple virtual machine written in x86_64 assembly, Onramp gradually built an assembler, C compiler, and other tools, ultimately compiling and running DOOM. While performance is currently limited, Onramp demonstrates impressive self-hosting capabilities and cross-platform potential. Its long-term goal is to enable compilation and execution of code on any architecture, even those of alien civilizations, preserving our cultural and computing heritage for the distant future.
