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

Contributor guide

Research direction
Study the existing code generation in Walt, identify how instructions are emitted, and design a dead code elimination pass that can be optionally applied during compilation. Start by examining the AST and code emission flow.
