gyb

A bytecode interpreter for the Garter & Gasm programming languages

Purpose

gyb is intended to function as a portable bytecode interpreter. gyb's architecture is designed to be close-enough to a real machine that an assembly language designed to target this bytecode can be translated to real machine-code somewhat trivially.

Implementation

gyb is based on a "ture", a register-based turing computer that runs just the process and has wrappers for common syscalls. It has a very limited instruction set and it's bytecode is intended to resemble RISC-V and x86-64.

gyb is also written in C, and will stay that way. I plan to make alternative versions so that there's more options for bootstrapping the Garter compiler-chain, but I think having a version of gyb written in C at every step in its life-cycle will be really important to the accessibility of the language as a whole.

Limitations and Scope

gyb is only intended to run on 64-bit machines, and building a version that runs on 32-bit computers isn't really in my plans. Additionally, the gyb interpreter can only handle a small subset of system calls. This program is intended to function as part of the Garter cross-compilation stage, and to act as a target for Gasm assembly. Anything beyond those two goals is outside the scope of this project.
