Oreo's Virtual Machine (OVM)
A stack based virtual machine in C11. Deals primarily in bytes, doesn't make assertions about typing and is very simple to target.
Instructions to target
You'll need inst.h for the instruction API. You
must convert user programs to instructions via inst_t, then emit
bytecode via insts_write_bytecode*.
This is all that is necessary to create a language which targets this virtual machine. To execute that bytecode, a user must use my virtual machine program.
