Overview

Package dce implements dead code elimination for WGSL modules.

DCE works by: 1. Finding entry points (@vertex, @fragment, @compute functions) 2. Building a dependency graph of symbol references 3. Marking all symbols reachable from entry points as "live" 4. Filtering out declarations for non-live symbols during printing

Functions

func IsDeclarationLive

func IsDeclarationLive(decl ast.Decl, symbols []ast.Symbol) bool

IsDeclarationLive returns true if the declaration should be included in output.
