### Function Analysis

Total functions: 591

Top modules by function count:
  core                            587 functions ( 99.3%)
  env                               4 functions (  0.7%)

## Optimization Insights

- Code size is over 100KB. Consider:
  - Enabling link-time optimization (LTO)
  - Using ReleaseSmall optimization mode
  - Removing unused features or modules
- High function count (591). Consider:
  - Checking for duplicate generic instantiations
  - Combining similar small functions
  - Using function deduplication

## Further Optimization Tools

1. wasm-opt -Oz input.wasm -o output.wasm  # Binaryen size optimization
2. twiggy top input.wasm                   # Show largest code sections
3. wasm-decompile input.wasm               # Analyze generated code
