- `integer-length` `a` → number of bits needed to represent a
Steps:
- [ ] Spec: add entries to `spec/primitives.sx` with type signatures.
- [ ] OCaml: implement in `hosts/ocaml/sx_primitives.ml` using OCaml `land`/`lor`/`lxor`/`lnot`/`lsl`/`lsr`.
- [ ] JS bootstrapper: implement in `hosts/javascript/platform.js` using JS `&`/`|`/`^`/`~`/`<<`/`>>`.
- [ ] Tests: 25+ tests in `spec/tests/test-bitwise.sx` — basic ops, shift left/right, negative numbers, popcount.
- [ ] Commit: `spec: bitwise operations (bitwise-and/or/xor/not, arithmetic-shift, bit-count)`
- [x] Spec: add entries to `spec/primitives.sx` with type signatures.
stdlib.bitwise module with 7 entries appended to spec/primitives.sx.
- [x] OCaml: implement in `hosts/ocaml/sx_primitives.ml` using OCaml `land`/`lor`/`lxor`/`lnot`/`lsl`/`asr`.
land/lor/lxor/lnot/lsl/asr in sx_primitives.ml. bit-count: Kernighan loop. integer-length: lsr loop.
- [x] JS bootstrapper: implement in `hosts/javascript/platform.js` using JS `&`/`|`/`^`/`~`/`<<`/`>>`.
stdlib.bitwise module added to PRIMITIVES_JS_MODULES. bit-count: Hamming weight. integer-length: Math.clz32.
- [x] Tests: 25+ tests in `spec/tests/test-bitwise.sx` — basic ops, shift left/right, negative numbers, popcount.
26 tests, 158 assertions, all pass OCaml+JS.
- [x] Commit: `spec: bitwise operations (bitwise-and/or/xor/not, arithmetic-shift, bit-count)`

- 2026-04-26: Phase 7 complete — bitwise-and/or/xor/not + arithmetic-shift + bit-count + integer-length. OCaml: land/lor/lxor/lnot/lsl/asr + Kernighan popcount + lsr loop for integer-length. JS: bitwise ops + Hamming weight + Math.clz32. 26 tests, 158 assertions, all pass. a8a79dc9.
- 2026-04-26: Phase 6 complete — JS+Tests+Commit all ticked. JS needed no changes (spec-level forms). 40/40 ADT tests pass JS. 2032/2500 JS total (+67 vs phase-4). Phase 6 fully landed: 6c872107+0dc7e159+5d1913e7. Phase 7 (bitwise) next.
- 2026-04-26: Phase 6 OCaml done — Dict-based ADT (no native SxAdt type needed); hand-written sf_define_type in bootstrap.py FIXUPS (skipped from transpile — &rest params + empty-dict {} literals); registered via register_special_form; step_limit/step_count added to PREAMBLE. 172 assertions pass (test-adt). Full suite 4280/1080 (was 4243/1117, +37). Committed 5d1913e7.
- 2026-04-26: Phase 6 Spec match done — ADT case added to match-pattern in spec/evaluator.sx: checks (list? pattern)+(symbol? first)+(dict? value)+(get value :_adt), then matches :_ctor+arity and recursively binds field patterns. No-clause error now uses make-cek-value+raise-eval-frame so guard can catch it. 20 new match tests pass; 40/40 total ADT tests green. Zero regressions.
