A comment on Selfie – Tiny self-compiling C compiler, RISC-V emulator and hypervisor.

I think Oberon would be a better candidate for this than C. You could get a tiny and extremely fast compiler for a full-featured programming language.

You can get a proper C compiler in 2KLOC [or under 5Kloc of assembly https://github.com/oriansj/mescc-tools-seed/blob/master/x86/... | https://github.com/oriansj/mescc-tools-seed/blob/master/x86/...] Covering things like gotos, inline assembly, structs, unions, arrays and dozens of types and primitives.

Oberon doesn't provide much advantage over that.

Funny because Selfie reminds me of a maximally compact version of http://www.projectoberon.com/

at the bottom of the linked page the author explicitly references oberon as a source of inspiration for this project

I'm looking into self-hosting compilers, is there a good link for Oberons code that achieves this? Or you just are mentioning that Oberon would probably be able to if one were implemented?

Oberon is implemented in itself: http://www.projectoberon.com

The implementation includes the hardware too.

Taken together, the system including single-tasking OS, windowing system and Oberon takes about 9000 lines of code.

Even better, A2/bluebottle is multithreaded with a ZUI and runs faster than Linux:

Also, following on from A2, Composita introduces a component architecture to allow managed memory without GC, and contextless switches (IMHO better than Rust):

You might be interested in oberonc [0] an oberon-07 self-hosting compiler for the JVM.
