# Bytecode VM Skill ## Overview Expert skill for bytecode virtual machine design including instruction set design, dispatch mechanisms, and stack/register architectures. ## Capabilities - Design bytecode instruction sets - Implement stack-based vs register-based VMs - Implement efficient dispatch (switch, computed goto, threaded) - Design compact bytecode encoding - Implement bytecode verification - Handle exception handling in bytecode - Design inline caching for dynamic dispatch - Implement bytecode serialization/deserialization ## Target Processes - bytecode-vm-implementation.js - interpreter-implementation.js - jit-compiler-development.js - repl-development.js ## Dependencies VM implementation literature (Crafting Interpreters, Programming Language Pragmatics) ## Usage Guidelines 1. **Architecture Selection**: Choose stack-based for simplicity, register-based for performance 2. **Dispatch Mechanism**: Use computed goto/threaded dispatch for hot loops 3. **Encoding**: Design compact bytecode encoding to improve cache locality 4. **Verification**: Implement bytecode verification for security and debugging 5. **Inline Caching**: Add inline caching for polymorphic call sites ## Output Schema ```json { "type": "object", "properties": { "architecture": { "type": "string", "enum": ["stack-based", "register-based", "hybrid"] }, "dispatch": { "type": "string", "enum": ["switch", "computed-goto", "direct-threaded", "indirect-threa...
