Description

Goal

Create an optimizing pass.

Overview

Go nuts? There is zero static optimization currently, everything written is emitted.

Dead code elimination sounds great. AssemblyScript does it, which is dope.

Acceptance Criteria

  • It works
  • It's tested
  • It's opt-in and configurable

Research direction
Explore the existing Walt codebase to understand the current compilation pipeline. Look at the AssemblyScript optimizer implementation for inspiration. Discuss with maintainers to narrow down the scope (e.g., which optimizations are prioritized). Focus on dead code elimination as a starting point.
