WaferConfig: unified config controlling all optimizations individually. ForthVM::new_with_config(config) to create VMs with custom optimization settings. All 8 switchable optimizations: peephole, constant_fold, strength_reduce, dce, tail_call, inline (IR passes) + stack_to_local_promotion (codegen). Benchmark framework (crates/core/tests/benchmark_report.rs): - 7 Forth benchmarks: Fibonacci, Factorial, SumRecurse, NestedLoops, GCD, MemFill, Collatz - Correctness verification across all configs (runs in CI) - Full report with 128 optimization combinations (cargo test --ignored) - Measures execution time, compilation time, WASM module bytes - CONSOLIDATE impact comparison Key findings from benchmark report: - Inlining: -77% exec time on Fibonacci, -92% on Collatz - Stack-to-local promotion: -5.5% WASM module size - CONSOLIDATE: -72% exec time on Fibonacci (call_indirect -> direct call) - All optimizations combined: best overall performance
