Could you build this?
No Designing novel minimal compiler architectures and language kernels (GDSL) in hundreds of lines of code requires deep programming language theory and compiler internals expertise.
What it would actually take: Building a custom compiler kernel supporting C and Lisp subsets demands deep systems programming and PL theory expertise (AST transformations, register allocation, bytecode VM or machine code emission). The architecture centers on an ultra-compact intermediate representation and minimal runtime kernel. Vibe coding can replicate common toy AST parsers, but crafting an original, highly compressed 800-line kernel requires specialized human insight.
Discussion
20 comments analyzed.
Competitors mentioned: GCC, LLVM, Mu (similar low-level compiler project), xcc700 (700-line C compiler)
Concerns raised: Not yet self-hosting (Lisp and C compilers cannot compile themselves), Only subset implementations, not full language compilers, No code emission to assembly/LLVM IR/machine code yet, only AST interpretation, Lacks backend implementation (acknowledged as biggest gap), Performance not yet a target
Feature requests: Backend code generation (assembly/LLVM IR/machine code emission), MIX (code emission layer) implementation for different architectures, Self-hosting capability, Full C and Lisp compiler implementations beyond subsets, Operating system kernel implementation
