M2-Planet

This shell.c can be compiled from c89cc.sh itself: https://gist.github.com/alganet/1513d7b6abef5c1a53a324d897c3... Ouroboros self-hosting. They can self-host one another. The idea is to make shell.c compile from an even simpler C compiler, such as M2-Planet: https://github.com/oriansj/M2-Planet Let me remind you that current stage0 bootstraps tinyc from mes, which is an interpreted lisp. It's not that different from the shell architecturally. The current stage0 also features kaem as one of the first dependencies. kaem is, in fact, a simpler version of the bourne shell. It's always a tower. You'll never get a one single clean dependency pass in bootstrapping.

but parsing command line arguments is a solved problem https://github.com/oriansj/M2-Planet/blob/master/cc.c#L40

The best things about compilers is that they have gentle ramps for learning. If you start simple enough, https://github.com/oriansj/M2-Planet the rest just becomes just add one more thing... It even works if you start from zero: https://github.com/oriansj/mescc-tools-seed

Yes, read this https://github.com/oriansj/M2-Planet and you will know how a cross platform self-hosting C compiler works in 1,982 lines of code and if you want to know how an assembler works read this: https://github.com/oriansj/mescc-tools/ only about 562 lines for the linker, 645 for the macro assembler and 204 lines if you want dwarf stubs in your binaries. Oh and it is cross platform too

The C version is alot easier to read: https://github.com/oriansj/M2-Planet

> Since Guile requires C, you need a binary C compiler at the very least to bootstrap it from the bare minimum. You do need a C compiler, but there is work underway to bootstrap the C compiler with ... a C compiler written in Scheme :) This Scheme interpreter (called "mes") can be built with the M2 Planet transpiler: https://gitlab.com/janneke/mes/ https://github.com/oriansj/m2-planet

Actually you missed a bunch. MesC is soon going to be bootstrapped by M2-Planet https://github.com/oriansj/M2-Planet Which is in the process of becoming bootstrapped via stage0 https://savannah.nongnu.org/projects/stage0/ Which bootstraps off a sub 240Byte hex Monitor and is hardware neutral.

Posts like this make me think of this: https://github.com/oriansj/M2-Planet A C compiler with support for inline assembly, gotos, structs and weighs under 2000lines and is self hosting.

as there is a project aiming to "bootstrap the world" https://savannah.nongnu.org/projects/stage0/ and they hand wrote a FORTH http://git.savannah.nongnu.org/cgit/stage0.git/tree/stage2/f... and a compacting garbage collecting lisp http://git.savannah.nongnu.org/cgit/stage0.git/tree/stage2/l... and their opinion was that it was easier to do the lisp than it was to do the FORTH. Although right now they are trying to improve their C Compiler prototype https://github.com/oriansj/M2-Planet before they convert it to assembly
