ok2	1c0df608c3	Remove unused stub files: forth/, words/, compiler.rs, primitives.rs, types.rs ... All were planning artifacts never imported or loaded: - forth/ (4 .fth files): commented-out TODO stubs, never loaded at startup - crates/core/src/words/mod.rs: empty module with commented-out submodules - compiler.rs: placeholder, all compiler logic lives in outer.rs - primitives.rs: placeholder, all primitives registered in outer.rs - types.rs: StackType/StackEffect defined but never imported anywhere	2026-04-02 13:52:45 +02:00
ok2	94f6cb6941	Add switchable optimization config and benchmark framework ... 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	2026-04-02 12:24:57 +02:00
ok2	7d9937d0d8	Initial commit: WAFER (WebAssembly Forth Engine in Rust) ... Optimizing Forth 2012 compiler targeting WebAssembly with IR-based compilation pipeline, multi-typed stack inference, subroutine threading, and JIT/consolidation modes. Rust kernel with ~35 primitives and Forth standard library for core/core-ext word sets.	2026-03-29 22:30:18 +02:00
