Stack-to-local promotion (Phase 1: straight-line code):
- Words with no control flow/calls use WASM locals instead of memory stack
- Stack manipulation (Swap, Rot, Nip, Tuck, Dup, Drop) emits ZERO instructions
- ~7x instruction reduction for arithmetic-heavy words like DUP *
- Pre-loads consumed items from memory, writes results back at exit
Consolidation recompiler (CONSOLIDATE word):
- Recompiles all IR-based words into single WASM module
- Direct call instructions instead of call_indirect through function table
- Cranelift can inline and optimize across word boundaries
- All control flow variants support consolidated calls
342 unit tests + 11 compliance, all passing.
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.
