AutoVM Interpreter

AutoVM is Auto's dedicated virtual machine and interpreter, designed to run Auto code efficiently across all supported platforms.

Architecture

AutoVM uses a register-based bytecode virtual machine with:

Ahead-of-Time (AOT) compilation for production builds
Just-in-Time (JIT) compilation for hot paths
Incremental compilation for fast development cycles

Hot Reloading

During development, AutoVM supports hot reloading of code changes without restarting the application. This works for:

Function body updates
Type definition changes
Actor message handlers

Cross-Platform

AutoVM runs on:

Desktop: Windows, macOS, Linux
Mobile: iOS, Android
Embedded: bare-metal with no OS
Web: via WebAssembly transpilation

Debugging

AutoVM includes a built-in debugger with:

Breakpoints and single-stepping
Variable inspection
Memory profiling
Actor message tracing
