Loop counters, bitwise ops, and `| 0` coercions qualify. This eliminates `fptosi/sitofp` round-trips per iteration. +- **Bounds elimination**: `for (let i = 0; i < arr.length; i++) arr[i]` — the compiler caches `arr.length` once and records `(i, arr)` in `bounded_index_pairs`, emitting raw `getelementptr + load` without runtime bounds checks. +- **Integer modulo**: `%` on provably-integer operands emits `fptosi → srem → sitofp` instead of `fmod` (a libm call on ARM — ~30ns vs ~1 cycle). +- **Inline `.length`**: `PropertyGet` for `.length` on arrays/strings unboxes the pointer and loads from offset 0 directly. +- **Numeric class fields**: `this.value + 1` where `value: number` skips `js_number_coerce` wrapping, enabling LLVM GVN/LICM. +- **Scalar replacement**: Non-escaping object literals, array literals, and `new` expressions are decomposed into per-field stack allocas — zero heap allocation.

Runtime Built-in Type Support + +### String (`StringHeader`) + +- UTF-8 (WTF-8 for lone surrogates) heap-allocated with `utf16_len`, `byte_len`, `capacity`, `refcount`, `flags`. +- **SSO**: strings ≤5 bytes encoded inline in the NaN-box payload — no heap allocation. +- **In-place append**: `refcount == 1` enables O(n) amortized `js_string_append` instead of always-allocating `js_string_concat`. +- **Chain optimization**: `a + b + c` collapses to `js_string_concat_chain` (single allocation). +- SIMD-optimized operations (NEON/SSE2 for string scanning). [9](#0-8) + +### Array (`ArrayHeader`) + +- Inline elements (NaN-boxed `f64`) follow the header in memory. +- `length` and `capacity` at fixed offsets for inline codegen. +- Numeric arrays can be "downgraded" to typed `f64[]` for SIMD vectorization. + +### BigInt (`BigIntHeader`) + +- 1024-bit (16 × `u64` limbs, little-endian). Sized for secp256k1 intermediate products. +- Allocated from arena bump allocator (not `gc_malloc`) for lower overhead. [10](#0-9) + +### Map / Set + +- `MapHeader` + `SetHeader` with side-table indices: `MAP_INDEX` (numeric keys), `MAP_STRING_INDEX` (FNV-1a content hashes for GC-safe string lookup), `SET_INDEX`. +- O(1) average lookup; content-based equality for strings. + +### Buffer (`BufferHeader`) + +- Layout matches `ArrayHeader` (length at offset 0, capacity at offset 4). +- Small buffer slab allocator for buffers < 256 bytes. +- `BUFFER_REGISTRY`, `ARRAY_BUFFER_REGISTRY`, `BUFFER_AB_ALIAS` for `instanceof` and aliasing checks. + +### Date + +- Stored as raw `f64` timestamp. `DATE_REGISTRY` tracks bit patterns for `instanceof Date`. Invalid Date = `DATE_NAN_BITS` (`0x7FF8_0000_0000_0DA7`). [11](#0-10) + +### Symbol + +- `SymbolHeader` allocated on heap, tagged with `POINTER_TAG`. `Symbol.for` / `Symbol.keyFor` supported via a global registry. + +### RegExp (`RegExpHeader`) + +- Backed by Rust's `regex` crate. Stores compiled `Regex`, original pattern/flags, and `last_index` for stateful execution. [12](#0-11) + +--- + +## 4. Object Model & Dynamic Dispatch + +### `ObjectHeader` Layout + +Every heap object has: `object_type` (u32), `class_id` (u32), `field_count` (u32), `keys_array` pointer. Inline property slots follow immediately in memory. + +- **Shape caching**: Objects with the same key set share a `keys_array` pointer. +- **`KEYS_INDEX`**: FNV-1a hash map built when `keys_array.length > 32` for O(1) lookup. +- **`OVERFLOW_FIELDS`**: TLS `PtrHashMap>` for dynamically-grown objects. [13](#0-12) + +### VTable / Dynamic Dispatch + +`CLASS_VTABLE_REGISTRY` maps `class_id` → `ClassVTable` (method name → function pointer). `js_native_call_method` is the dispatch entry point: + +1. `JS_HANDLE_TAG` → V8/QuickJS bridge +2.

[15](#0-14) + +### Mark-Sweep Collector + +- **Mark**: precise shadow stack roots + `MALLOC_STATE` + conservative C-stack scan (any bit pattern matching a heap address is treated as a root → "pinned"). +- **Sweep**: malloc objects without mark bit are freed; arena blocks without live objects are reset. +- **Write barriers**: emitted by codegen for property/array stores to track old→young references. [16](#0-15) [17](#0-16) + +--- + +## 6. Closures, Async, & Event Loop + +### Closures + +`ClosureHeader`: `func_ptr` (usize), `capture_count` (u32, high bit = `CAPTURES_THIS_FLAG`), `type_tag` (`CLOSURE_MAGIC 0x434C_4F53`), variadic `captures[]` (u64 slots). Mutable captures are heap-boxed. Side-tables: `CLOSURE_REST_REGISTRY`, `CLOSURE_ARITY_REGISTRY`, `DISPATCH_CACHE`. + +### Async/Await + +Lowered in two passes: +1. `transform_async_to_generator`: `await` → `yield`, marks `is_generator = true`, `was_plain_async = true`. +2. `transform_generators`: converts to a `while(true)` + `if (__state === N)` state machine. [18](#0-17) + +### Promise & Microtask Queue + +`js_promise_run_microtasks` drains the microtask queue. Uses `setjmp` to catch throws from callbacks and reject the chained promise without exiting the loop. `MT_STEP_CHAIN_REUSE_HIT` optimization avoids fresh Promise allocations during `await` chains. [19](#0-18) + +### Async Bridge (Rust Futures → TS Promises) + +Tokio worker threads cannot allocate JS objects (thread-local arenas). Results go through `PENDING_DEFERRED` with a `converter` closure that runs on the main thread. Promises are pinned (`GC_FLAG_PINNED`) while a tokio worker holds them. [20](#0-19) + +### Event Loop + +`js_wait_for_event` blocks on a `Condvar` until a timer deadline or `js_notify_main_thread` signal. Adaptive spin-throttle prevents 100% CPU on past-deadline timers. + +### Threading + +Shared-nothing: each thread has its own arena + GC. Values cross boundaries via `SerializedValue` (deep copy). `parallelMap`, `parallelFilter`, `spawn`. No `SharedArrayBuffer` or `Atomics`. [21](#0-20) + +--- + +## 7. JS Interop Escape Hatch + +When Perry cannot compile a module natively, `--enable-js-runtime` embeds V8/QuickJS. JS objects are represented as `JS_HANDLE_TAG` NaN-boxed values. `JS_HANDLE_CALL_METHOD`, `JS_HANDLE_ARRAY_GET`, `JS_HANDLE_OBJECT_GET_PROPERTY` are function pointers registered by the JS runtime bridge. [22](#0-21) + +--- + +## 8. Gaps in the AOT Runtime + +The following are confirmed gaps, stubs, or architectural limitations for a **complete** AOT TypeScript runtime: + +### A. Weak Reference Semantics (Stub) + +`WeakRef`, `WeakMap`, `WeakSet`, and `FinalizationRegistry` expose the correct API shape but are **not GC-accurate**. `WeakRef` holds a **strong** reference internally. `FinalizationRegistry` records registrations but **never fires cleanup callbacks**. The GC's mark phase does not track weak references. [23](#0-22) + +### B. `AsyncLocalStorage` / `async_hooks` — Partial + +`AsyncLocalStorage` and `async_hooks.createHook` have native runtime implementations, but CLAUDE.md explicitly flags `#788` (real `AsyncLocalStorage` tracking across `await`/microtasks/timers) and `#789` (real `async_hooks.createHook` lifecycle + asyncId) as open issues — today these are described as "name-only stubs" for the full lifecycle semantics. [24](#0-23) + +### C. `Proxy` / `Reflect` — Not Supported + +`Proxy` is not a full engine-level trap layer. `Reflect.metadata` and general `Reflect` API calls outside decorator syntax are unsupported. `Object.setPrototypeOf` is modeled as a no-op (Perry's class IDs are baked at allocation time). [25](#0-24) + +### D. `eval()` / `new Function()` / Dynamic `import()` — Not Supported + +AOT compilation is fundamentally incompatible with runtime code generation. Dynamic `require()` and `await import()` are also unsupported; only static ESM imports are allowed. [26](#0-25) + +### E. `SharedArrayBuffer` / `Atomics` — Not Supported + +Perry's shared-nothing threading model (deep-copy across boundaries) is architecturally incompatible with `SharedArrayBuffer`.

If so, it emits +`fptosi → srem → sitofp` instead of `frem double`. + +On ARM, `frem` lowers to a **libm function call** (`fmod`) — there is no +hardware remainder instruction for f64. That's ~30 ns per call, plus the +overhead of a real function call in a tight loop. `srem` is a single ARM +instruction at ~1–2 cycles. The ratio is why `accumulate` shows Perry at +25 ms vs every other language at ~96 ms — the gap is entirely `srem` vs +`fmod` dispatch cost. + +This is a **type-driven** optimization, not a language-capability +optimization. Every language in the suite would hit the same 25 ms if its +benchmark used `int64`/`i64`/`long` instead of `double`. The optimized +variants (phase 2, see `RESULTS_OPT.md`) confirm this. Perry's win on +`accumulate` is: it can infer, from the TS source code and the absence of +non-integer operations on the accumulator, that the `double` here is always +holding an integer value, and swap the lowering to use the integer +instruction set — while the human-written TS source still looks like +`sum += i % 1000`. + +### 3. i32 loop counter + bounds elimination + +`crates/perry-codegen/src/stmt.rs:651-782`.

It allocates a parallel **i32 counter slot** alongside the f64 counter + (`i32_counter_slots`). +2. It caches `arr.length` once at loop entry (`cached_lengths`). +3. It records the `(counter, array)` pair as statically in-bounds + (`bounded_index_pairs`) — subsequent `arr[i]` reads skip the runtime + length load and bounds check entirely. + +The array-access codegen sites consult these maps and emit a raw +`getelementptr + load` when available. On `array_write` and `array_read`, +this produces code that LLVM can autovectorize into NEON 2-wide f64 SIMD, +matching `-O3 -ffast-math` C++ output. + +**Important**: this is *not* "Perry removes safety." It's static proof that +the bounds check is dead. The JS semantics are preserved: you can still +read past the end of an array, you still get `undefined`. The compiler has +just observed, for this specific `for` loop shape, that the index is bounded +by the length. Rust's iterator path (`.iter().sum()`) does the same analysis +at the IR level — and matches Perry to the millisecond on `array_read` +when used.

The problem is that too much of the system still uses the universal `JSValue` representation too early. The fastest Perry should look less like “native code calling a JS runtime helper often” and more like “a static compiler that only falls back to JS dynamic semantics where the program actually needs them.” + +## Main guidance + +The core rule should be: + +```text +Do not lower TypeScript values directly to JSValue. +Lower them to typed SSA values first. +Box only at dynamic boundaries. +``` + +A good target model is: + +```text +TypeScript/HIR type + → Perry type facts + → representation-specific IR + → LLVM native value + → JSValue only if needed +``` + +For example: + +```text +number → f64 +integer-stable number → i32 / u32 / i53 +boolean → i1 +string → PerryStringRef, not raw JSValue +class Point → ptr PointObjectLayout +number[] packed → ptr ArrayF64 +any / unknown → i64 JSValueBits +JS interop handle → JSHandleValue +``` + +This matters because LLVM can optimize `i32`, `double`, `ptr`, and typed loads. It cannot reason well about every value being a NaN-boxed `f64`. Perry’s current architecture says every JS value crossing a function boundary is a NaN-boxed `f64`, with tags for strings, objects, int32, BigInt, short strings, handles, and singleton values. That is fine as a **public ABI**, but it should not be the default internal representation inside optimized functions. + +## Use `JSValue` as an ABI, not as the optimizer’s native type + +Keep `JSValue` for: + +```text +public function boundaries +unknown calls +any / unknown +dynamic property access +generic arrays +object dictionaries +exceptions +closures that escape +Promise/microtask storage +thread serialization +V8/QuickJS bridge values +``` + +But inside a compiled function, Perry should prefer typed values. + +Example target shape: + +```text +// Public generic trampoline. +foo$jsvalue(JSValue a, JSValue b) -> JSValue { + if a,b are numbers: + return box_number(foo$number_number(a as f64, b as f64)) + else: + return foo$generic(a, b) +} + +// Internal typed clone. +foo$number_number(f64 a, f64 b) -> f64 { + return a + b +} +``` + +The same applies to classes: + +```text +Point.distance$typed(ptr Point, ptr Point) -> f64 +Point.distance$generic(JSValue this, JSValue other) -> JSValue +``` + +This gives Perry a static-compiler version of what a JIT does dynamically: one generic path for correctness, and typed paths for speed. + +## Represent `JSValue` bits as `i64` in LLVM IR + +Even if the external ABI still passes `JSValue` as `f64`, Perry should seriously consider representing boxed values internally as `i64` bit patterns, not as LLVM `double`. + +NaN-boxing depends on preserving payload bits exactly. But LLVM and CPU floating-point optimizations naturally treat `double` as a numeric value, not as a tagged pointer carrier. Perry’s own `JSValue::is_number` logic distinguishes real IEEE numbers from Perry-owned positive quiet-NaN tag bands, and the runtime already has careful handling for tags such as `SHORT_STRING_TAG`, `STRING_TAG`, and `POINTER_TAG`. + +Recommended internal split: + +```text +NumberValue = double +BoxedValue = i64 +PointerValue = ptr +BoolValue = i1 +Int32Value = i32 +Uint32Value = i32 with unsigned interpretation +``` + +Only bitcast between `i64` and `double` at ABI edges where the current ABI requires `f64`. + +This also avoids accidental optimizer corruption from fast-math flags. JavaScript numeric semantics include `NaN`, infinities, and signed zero, so broad fast-math should not be applied to general JS `number` operations unless Perry has proven the operation is in a restricted numeric domain. + +## Build a richer type-fact lattice + +Current HIR types are useful but too coarse. `Type::Number`, `Type::String`, `Type::Array(elem)`, `Type::Named(name)`, and `Type::Any` are not enough for aggressive lowering. Perry should keep HIR types, then add a second layer of **type facts**. + +Recommended fact shape: + +```text +Value facts: + kind: number | int32 | uint32 | int53 | bool | string | object | array | bigint | any + nullability: non-null | nullable | nullish | unknown + representation: unboxed | boxed | pointer | handle + range: integer bounds if known + constant: literal value if known + +Array facts: + element kind: f64 | i32 | uint32 | JSValue | string | object + packed vs holey + length stable inside region + capacity stable inside region + no external alias + no body write can grow/shrink + +Object facts: + exact class id + exact shape id + field layout + field pointer bitmap + frozen/sealed/no-extend state + dictionary fallback possible or impossible + +Effect facts: + may allocate + may call unknown code + may mutate array length + may mutate object shape + may throw + may access JS bridge + may run microtasks +``` + +This turns Perry’s optimizer from “infer a type once” into “carry a proof.” That proof then decides whether Perry emits raw native loads, bounds checks, dynamic dispatch, write barriers, or generic helper calls. + +## Generalize the existing integer fast path + +Perry already has a real performance win here. It recognizes integer-valued expressions, tracks `i32` loop-counter slots, uses integer modulo instead of `fmod`, and avoids repeated `fptosi/sitofp` round-trips in hot array-walking loops. The provided benchmark methodology says this is why integer modulo can become a single integer instruction instead of a libm `fmod` call, and why array read/write loops can become raw `getelementptr + load` patterns that LLVM can vectorize. + +The next step is to expand the numeric lattice: + +```text +i32 signed ToInt32 domain +u32 unsigned ToUint32 domain +i53 safe JS integer domain +f64 general JS number +f64-nonNaN proven non-NaN +f64-finite proven finite +``` + +Do not force everything integer-like into `i32`. JavaScript has several subtly different integer domains: + +```text +x | 0 → signed i32 +x >>> 0 → unsigned u32 +array idx → uint32-ish but constrained by length +number → f64, often integer-valued but not always safely i32 +``` + +Perry’s comments already show why this matters: previous `i32` shadowing could silently corrupt accumulators that were integer-stable but not actually safe as signed 32-bit values. The current gating via index-used locals, strictly bounded locals, and unsigned locals is the right direction. Extend that into a first-class numeric domain system rather than a set of local special cases. + +## Make arrays representation-specialized + +Arrays should not all be `ArrayHeader + JSValue[]`. + +Recommended array kinds: + +```text +PackedF64Array +PackedI32Array +PackedU32Array +PackedStringArray +PackedObjectArray +PackedValueArray +HoleyValueArray +DictionaryArray +TypedArray-backed variants +``` + +For `number[]` in a proven packed numeric loop, Perry should lower: + +```ts +for (let i = 0; i < arr.length; i++) { + sum += arr[i] +} +``` + +to roughly: + +```text +arr_ptr = checked_unbox_packed_f64_array(arr) +len = arr.length +data = arr.data + +for i32 i in [0, len): + sum = fadd sum, load data[i] +``` + +No per-iteration NaN-box decode. No per-iteration length load. No bounds check if the loop proof establishes `i < arr.length`. No runtime helper call. Perry already has a narrower version of this with cached lengths, `bounded_index_pairs`, and `i32_counter_slots`; generalize it to element-kind-specialized arrays. + +For stores, use transitions: + +```text +PackedF64Array + number store → stay PackedF64Array +PackedF64Array + undefined store → transition to PackedValueArray or HoleyValueArray +PackedI32Array + f64 store → transition to PackedF64Array or PackedValueArray +PackedObjectArray + object D → stay only if D <= C-compatible +``` + +This is where Perry can exploit its AOT restrictions. Since Perry does not support general `eval`, `new Function`, dynamic import, dynamic `require`, full prototype mutation, or full Proxy trapping, it has fewer invalidation hazards than V8. Those limitations are not just compatibility gaps; they are optimization permissions. + +## Add array-loop versioning + +For uncertain arrays, compile two paths: + +```text +fast path: + guard array is PackedF64Array + guard no holes + guard length stable + run typed loop + +slow path: + generic JS array access +``` + +Example: + +```text +if likely(is_packed_f64_array(arr)) { + return sum_packed_f64(arr) +} +return sum_generic_jsvalue(arr) +``` + +This is AOT-friendly. It does not require a JIT. It only requires small guarded clones. + +Use this for: + +```text +Array.prototype.map/filter/reduce +for loops over arr.length +JSON parse/stringify internal loops +Buffer/Uint8Array loops +string scanning +numeric kernels +``` + +Code size must be controlled. Do not clone every function for every type combination. Clone only when: + +```text +function is hot by benchmark/profile +loop body is small +specialization removes helper calls +array kind is stable +generic fallback remains available +``` + +PGO is a good fit here because it lets the compiler choose which clones matter for real workloads. LLVM’s own documentation describes PGO as a way for a compiler to optimize according to how code actually runs, with representative profile selection being important. ([LLVM][1]) + +## Make object/class fields unboxed where possible + +Perry’s object model currently uses `ObjectHeader`, `class_id`, `field_count`, `keys_array`, inline property slots, shape caching, `KEYS_INDEX`, overflow fields, and vtable-based dynamic dispatch. That is a workable JS object model, but class instances with declared fields should not be treated like generic dictionaries in hot paths. + +For classes, generate fixed layouts: + +```ts +class Point { + x: number + y: number +} +``` + +Target layout: + +```text +ObjectHeader +class_id +shape_id +field_bitmap +x: f64 +y: f64 +``` + +Not: + +```text +ObjectHeader +keys_array = ["x", "y"] +slots[0] = JSValue(number) +slots[1] = JSValue(number) +``` + +The second layout is more dynamic, but much slower. The first layout gives LLVM ordinary typed loads: + +```llvm +%x_ptr = getelementptr %Point, ptr %p, field_x +%x = load double, ptr %x_ptr +``` + +For nullable/dynamic fields, use mixed layout: + +```text +f64 fields +i32 fields +pointer fields +JSValue spill fields +overflow dictionary +``` + +This also improves GC. A typed field layout gives the collector a pointer bitmap, so it scans only pointer fields instead of inspecting every slot dynamically. + +## Fix scalar replacement across method calls + +The current scalar replacement limitation is important: Perry can stack-allocate or decompose non-escaping object literals only when the object is accessed exclusively through field get/set; any method call defeats it. + +That should be one of the highest-priority compiler improvements. + +Example: + +```ts +class Point { + constructor(public x: number, public y: number) {} + sum() { return this.x + this.y } +} + +let p = new Point(x, y) +total += p.sum() +``` + +Current likely behavior: + +```text +allocate Point +store x/y +dynamic or semi-dynamic method call +load fields +GC-visible object +``` + +Target behavior: + +```text +p.x = scalar x +p.y = scalar y +inline Point.sum +total += x + y +no allocation +``` + +To get there, Perry needs method summaries: + +```text +method Point.sum: + receiver escapes? no + mutates receiver shape? no + reads fields: x, y + writes fields: none + may call unknown? no + may throw? no +``` + +Then escape analysis can treat simple method calls as field operations. LLVM’s SROA pass is specifically designed to break analyzable aggregate allocas into scalar SSA values, and its vectorizers can then operate on clean scalar/loop IR; Perry should feed LLVM IR that makes those passes obvious instead of hiding work behind runtime helper calls. ([LLVM][2]) ([LLVM][3]) + +## Replace stringly dynamic dispatch with IDs + +`js_native_call_method` currently receives a method name pointer and length, builds/uses a string name, handles JS handles, class static methods, vtable lookup, prototype objects, and fallback paths. That is correct but expensive for hot calls. + +For compiled code, method/property names should be lowered to interned IDs at compile time: + +```text +"toString" → SymbolId / PropertyId 17 +"value" → FieldId 3 +"length" → BuiltinPropertyId::Length +``` + +Then dispatch can be: + +```text +if exact class id known: + direct call function pointer + +else if class id known but subclass possible: + vtable[class_id][method_id] + +else: + generic js_native_call_method_by_id + +only final fallback: + js_native_call_method_by_string +``` + +Hot-path method calls should not allocate Rust `String`s, hash method names, or scan strings. For static class methods, the same ID system should apply. + +## Unify string lowering; eliminate the SSO footgun + +The current short-string optimization is valuable, but the strict `is_string()` versus `is_any_string()` distinction is a correctness and performance hazard. The context explicitly warns that `is_string()` only recognizes heap `STRING_TAG`, while `SHORT_STRING_TAG` can fall into wrong branches and even be dereferenced as a pointer if call sites are not careful. + +Recommended fix: + +```text +PerryStringRef: + Short { bytes[5], len } + Heap { ptr: *StringHeader } +``` + +Then generated code and runtime helpers should use one abstraction: + +```text +is_string_like(value) +string_len(value) +string_bytes(value) +string_materialize_if_needed(value) +``` + +Rename low-level predicates to make misuse hard: + +```text +is_heap_string() +is_short_string() +is_any_string() +``` + +Do not allow new runtime code to branch on `is_string()` unless the name means “any string.” For performance, specialize string operations: + +```text +short + short → inline small concat if result <= 5 +heap refcount == 1 → append in place +concat chain → one allocation +string scan → SIMD path +property key → interned ID / pointer identity +``` + +The provided context already describes SSO, in-place append, concat-chain optimization, and SIMD string scanning. The main improvement is making the type lowering and runtime API impossible to misuse. + +## Use Perry’s unsupported JS features as optimization assumptions + +Perry does not support or only partially supports several highly dynamic JS features: full `Proxy`, full `Reflect`, `eval`, `new Function`, dynamic import, user-space dynamic `require`, full prototype mutation, `SharedArrayBuffer`, and `Atomics`. + +That means Perry can assume much more than V8 in native-compiled mode: + +```text +class layouts do not get monkey-patched at runtime +prototype methods do not arbitrarily change +static ESM imports form a closed module graph +no eval can introduce new code +no SharedArrayBuffer means no cross-thread mutation races +deep-copy threading means local arrays are not concurrently modified +``` + +Perry should formalize this into compilation modes: + +```text +strict-native mode: + assumes Perry limitations + strongest type lowering + no dynamic fallback except explicit JS runtime bridge + +compat mode: + more JSValue paths + more guards + less layout specialization +``` + +This lets Perry turn compatibility limitations into performance wins without pretending to be fully dynamic JavaScript. + +## Add effect analysis before lowering + +Many current optimizations depend on proving that a loop body does not mutate `arr.length`, does not reassign the loop counter, and does not invalidate the cached length. Perry already does some of this for bounded index pairs. + +Make this a general effect system: + +```text +Effect::ReadsArrayLength(arr) +Effect::WritesArrayLength(arr) +Effect::WritesArrayElement(arr) +Effect::MayGrowArray(arr) +Effect::MutatesShape(obj) +Effect::CallsUnknown +Effect::Allocates +Effect::MayThrow +Effect::RunsMicrotasks +Effect::TouchesJSHandle +``` + +Then lowering decisions become principled: + +```text +Can cache arr.length? + yes if no effect in loop may write length or reassign arr + +Can eliminate bounds check? + yes if loop induction range is within cached length + +Can direct-load field? + yes if receiver shape is stable and no effect mutates it + +Can stack-allocate object? + yes if object does not escape through call, closure, return, throw, async, or unknown store + +Can skip write barrier? + yes if stored value is statically primitive or parent is young +``` + +This will improve both performance and correctness because optimizations become proof-based rather than pattern-based. + +## Emit better LLVM metadata + +Perry should make LLVM’s optimizer see what Perry already knows. + +For typed arrays and fixed class layouts, emit: + +```text +nonnull +dereferenceable(N) +align +noalias for fresh allocations +alias.scope / noalias for independent arrays +TBAA metadata for headers, lengths, capacities, fields, data buffers +range metadata for lengths, tags, enum values +cold/noinline for generic fallbacks +alwaysinline for tiny tag checks and unbox helpers +readonly/readnone/willreturn/nounwind where valid +``` + +LLVM’s LangRef documents `dereferenceable`, `noalias`, `alias.scope`, `TBAA`, and `range` metadata; these are exactly the kinds of facts Perry can provide from its type/layout system. ([LLVM][4]) ([LLVM][4]) ([LLVM][4]) ([LLVM][4]) + +The important point: do not merely generate “correct” LLVM IR. Generate IR that exposes aliasing, bounds, layout, and type facts. + +## Lower write barriers statically + +Write barriers should not be emitted as generic runtime calls for every store. + +For every store site, codegen should decide: + +```text +storing number/bool/null/undefined/int32? + no pointer child → no barrier + +parent proven young? + no old→young edge → no barrier + +child proven old or non-GC? + no young child → no barrier + +parent old and child maybe young? + inline fast card barrier +``` + +The GC context says Perry’s current barrier fires on every heap store emitted by codegen, decodes parent and child, checks old→young, and dirties a page when needed. That is semantically right, but it leaves too much work for runtime. + +Type lowering can remove many barriers before codegen: + +```text +obj.x = 3.14 // no barrier +obj.flag = true // no barrier +obj.count = i32 // no barrier +youngObj.child = y // no old→young barrier +oldObj.child = y // inline card barrier only if y may be young pointer +``` + +This also argues for unboxed class fields. A `number` field stored as raw `f64` never needs a GC barrier. + +## Improve Map/Set lowering with key-specialized tables + +The current runtime has separate side-table indices for numeric keys, string keys, and sets, with content hashing for strings. + +The compiler should exploit that: + +```ts +const m = new Map() +m.set(k, v) +m.get(k) +``` + +should lower to: + +```text +MapStringNumber +key: PerryStringRef / interned string id where possible +value: f64 +``` + +Not: + +```text +generic Map +generic hash +generic equality +boxed value +``` + +Recommended specializations: + +```text +Map +Map +Map +Map +Set +Set +``` + +For `Record` and object dictionaries, use the same idea: once an object crosses the `KEYS_INDEX_THRESHOLD`, compile dynamic key operations against a dictionary representation directly rather than repeatedly going through generic object field helpers. + +## Rework BigInt representation + +The current BigInt design uses fixed 1024-bit storage, mainly to satisfy crypto workloads where secp256k1 intermediates can exceed 512 bits. + +That is good for crypto kernels, but it is too heavy as the default BigInt representation. + +Recommended split: + +```text +SmallBigInt: + inline i64/u64 or two limbs + +MediumBigInt: + heap variable-limb Vec + +CryptoBigInt1024: + fixed 16-limb path for known crypto packages / specialized kernels +``` + +Then lowering can choose: + +```text +1n + 2n → SmallBigInt or constant fold +BigInt loop counter → SmallBigInt +crypto modular multiply → CryptoBigInt1024 +unknown BigInt expression → generic variable-limb BigInt +``` + +This prevents every BigInt from paying crypto-sized costs. + +## Treat async lowering as allocation lowering + +Perry already lowers async/await into generator/state-machine form, runs promise microtasks, and has optimized the microtask loop by using one outer `setjmp` instead of one per microtask. The async bridge also avoids creating `JSValue` objects on Tokio worker threads and defers conversion to the main thread because arenas are thread-local. + +The next performance step is to make async lowering typed: + +```text +async function f(): Promise +``` + +should become: + +```text +state machine result slot: f64 +Promise continuation: typed f64 until boxed +``` + +Avoid: + +```text +state machine slot: JSValue +every await result: boxed +every continuation: generic closure +``` + +Recommended async optimizations: + +```text +typed result slots in state machines +typed capture slots +static continuation structs instead of generic closures +Promise allocation reuse for await chains +no boxing until resolving externally-visible Promise +microtask queue entries specialized by callback signature +``` + +The existing `MT_STEP_CHAIN_REUSE_HIT` style optimization should be expanded into a general “typed async continuation” path. + +## Use internal typed calling conventions + +Perry’s monomorphization is already a strong asset. Generics are specialized into mangled function/class names such as `identity$number`. + +Extend that idea beyond TypeScript generics: + +```text +Function clone dimensions: + argument representation + return representation + receiver class id + array element kind + nullability + closure capture layout +``` + +Example: + +```text +sum$ArrayF64__f64 +sum$ArrayI32__i32 +sum$ArrayValue__JSValue +sum$generic +``` + +But control code size: + +```text +clone only loops/functions above threshold +clone only if helper calls disappear +clone only if call graph is stable +merge clones with same machine representation +cap clone count per function +use profile data to choose +``` + +This gives Perry a static analog to V8’s specialization without needing a JIT. + +## Add package-level specialization + +Perry can know the whole package at compile time. Use that. + +For npm/native packages that Perry supports directly, ship lowering profiles: + +```text +fastify: + object-shape stable request/response paths + string/header maps + async Promise chains + +mysql2: + row object shapes + date/string/buffer decoding + typed column arrays + +redis: + string/buffer heavy paths + command array flattening + +noble/ethers: + BigInt/Uint8Array crypto kernels + fixed-limb arithmetic +``` + +This should not be handwritten one-off hacks in codegen. It should be a declarative profile system: + +```text +known stable shapes +known method purity +known allocation patterns +known typed arrays +known no-dynamic-require subset +``` + +Then the normal optimizer consumes those facts. + +## Make lowering observable + +Before adding many optimizations, add a compiler report: + +```text +perry build --explain-lowering +``` + +For each function: + +```text +boxes inserted: 42 +unboxes inserted: 17 +js_number_coerce calls: 3 +runtime property gets: 8 +direct field loads: 21 +bounds checks eliminated: 14 +barriers eliminated: 32 +object allocations scalar-replaced: 6 +array kind: PackedF64Array +generic fallback emitted: yes +reason scalar replacement failed: method call escapes receiver +reason bounds check kept: loop body may mutate length +reason typed call failed: callee return type unknown +``` + +This will pay for itself quickly. Perry’s biggest optimization risk is silent missed lowering: code still works, but one helper call in a hot loop destroys performance. + +## Recommended implementation order + +First, split internal `JSValue` representation into `i64 JSValueBits` and typed native values. Keep the existing external ABI if needed, but stop letting LLVM see boxed values as ordinary floating-point values unless they are actually numbers. + +Second, add a `TypeFacts` pass after HIR lowering and before LLVM generation. This should compute numeric domains, array kinds, object shapes, nullability, escape state, and side effects. + +Third, implement late boxing. Function bodies should use native typed values; boxes should be inserted only at returns, unknown calls, dynamic stores, closure captures, async suspension, thread serialization, and JS interop. + +Fourth, create internal typed function clones plus generic trampolines. Start with `number`, `int32`, `boolean`, `string`, and packed numeric arrays. + +Fifth, generalize array lowering into packed/holey/value/dictionary representations. Make the existing bounded-index and cached-length logic a special case of a broader array-fact system. + +Sixth, make fixed class layouts use unboxed fields and direct method calls when the receiver class is exact. Add method purity/effect summaries so scalar replacement works across simple method calls. + +Seventh, replace string-name dispatch with interned property/method IDs. Keep string fallback for dynamic cases only. + +Eighth, unify string handling around `PerryStringRef` so SSO and heap strings share one safe lowering path. + +Ninth, specialize Map/Set/Record by key and value kind. + +Tenth, apply PGO to choose which typed clones to emit and which generic paths to mark cold. + +## What not to do + +Do not rely on TypeScript annotations as runtime truth. TypeScript types guide optimization, but values can still enter through `any`, unknown package boundaries, dynamic data, JSON, V8/QuickJS handles, or native callbacks. Use annotations as optimistic facts only when the compiler can prove the boundary is closed, or emit guards. + +Do not globally enable fast-math. JavaScript `number` semantics are not C `-ffast-math` semantics. Signed zero, `NaN`, infinities, and coercions matter. + +Do not solve performance primarily by adding more runtime helpers. The goal is fewer helper calls in hot paths. + +Do not let monomorphization explode code size. Specialization should be costed. + +Do not keep expanding object side tables for hot class instances. Use side tables for dynamic dictionaries; use fixed typed layouts for classes and stable shapes. + +## Bottom line + +The right direction for Perry is: + +```text +AOT TypeScript compiler + + typed SSA + + late boxing + + guarded typed clones + + packed array/object layouts + + effect/range/escape analysis + + LLVM metadata + + generic JSValue fallback +``` + +Perry should not try to beat V8 by making a faster generic JS object model. It should beat V8 where AOT has an advantage: closed-world TypeScript, fixed class layouts, static imports, typed arrays, monomorphized functions, predictable async state machines, and compiler-proven loops. + +The best single sentence guidance is: **make `JSValue` the fallback representation, not the default representation.** + +[1]: https://llvm.org/docs/HowToBuildWithPGO.html "How To Build Clang

A narrow value-first ordinary-expression path now keeps simple numeric literals, locals, local assignment, and numeric binary ops as `f64`, and simple boolean literals/locals/assignment/comparison/`!` as `i1`, until return/runtime materialization. Broad ordinary expression lowering is still predominantly generic `double` unless a local proof applies. Evidence: `representation_first_numeric_locals_stay_f64_until_abi` and `representation_first_boolean_locals_stay_i1_until_abi`. | +| `[~]` | Keep `JSValue` as ABI/fallback, not optimizer default | Public ABI remains `double`/NaN-box. First ordinary-function, own-instance-method, and local-closure typed-f64/typed-i1 candidates now keep raw `double`/`i1` clones behind public JSValue wrappers that guard arguments, call the typed clone on success, box/materialize at the ABI edge, and fall back to an internal generic body. Ordinary functions also have a first string passthrough clone shape: the internal clone passes raw `StringHeader*` handles as `i64`, the public wrapper guards/unboxes JS strings, boxes the raw result with `js_nanbox_string`, and falls back to the generic body; same-module direct `FuncRef` calls with proven string args can call that raw clone directly after guards. Local no-capture string closures now use the same closure-aware raw string ABI (`i64 %this_closure, i64 string args... -> i64 string`) behind a public JSValue wrapper and guarded direct local call path. Local typed closure clones now use a closure-aware internal ABI (`i64 %this_closure, typed args...`) and accept immutable typed captures for the conservative numeric/boolean slices. Ordinary functions now also cover a first mixed native predicate shape, `number... -> boolean`, by emitting an internal `i1(double, ...)` clone behind the public wrapper; same-module direct `FuncRef` calls now carry typed parameter reps and can call that clone directly after `f64` guards. Async, string methods/operators, dynamic string calls, string closure captures, escaping/unknown closures, mutable/boxed/`this`/`new.target` captures, inherited/dynamic method bodies beyond public wrapper dispatch, and most functions/methods still use generic ABI. | +| `[~]` | Use `i64 JSValueBits` internally for boxed values | `JsValueBits` records and selected production consumers exist, including write-barrier child selection, boxed local/parameter/PreallocateBoxes storage as raw `i64` box pointers, `array.push` slot/runtime-helper value selection, and dynamic property/index-set RHS selection before boxing at the store/helper edge, including array runtime-key index setters. `ExpectedNativeRep::JsValueBits` now tries value-first lowering for ordinary native expressions and direct `f64`/proven-`i1`/integer/native-handle/promise-boundary materialization to boxed bits before falling back through `JSValue`. Public boolean parameters in generic bodies still enter as JSValue ABI locals unless a typed clone owns the call path. Closure capture ABI, dynamic property/index helper edges beyond the covered store paths, and many generic expression paths still materialize through `double`. Evidence: `accepts_js_value_bits_materialization_transitions`, `artifact_records_direct_f64_to_js_value_bits_for_write_barrier`, `artifact_records_direct_i1_to_js_value_bits_for_write_barrier`, `artifact_records_write_barrier_child_js_value_bits`, `artifact_records_array_push_value_bits_before_slot_store`, `artifact_records_dynamic_property_set_value_bits_before_helper`, `artifact_records_dynamic_index_set_value_bits_before_helper`, and `artifact_records_array_runtime_key_index_set_value_bits_before_helper`. | +| `[~]` | Rich TypeFacts/effect/range/escape lattice | Array-kind, array-stability, noalias, effect, unknown-call, alias, aggregate identity exposure, materialization-hazard facts, and a first async/microtask escape fact now feed packed-f64 and cached-length proofs. Loop array-length consumers now emit accepted/rejected effect-fact artifacts, including explicit async/microtask rejection records when an `await` would make cached length or bounded-index lowering unsafe. Object facts, field-sensitive escape/range facts, broader async/microtask summaries, and wider consumer coverage remain incomplete. Evidence: `async_microtask_escape_is_tracked_as_effect_fact`, `loop_length_effect_artifact_records_consumed_preservation_fact`, `async_microtask_effect_blocks_length_and_bounds_proofs_with_artifact_reason`, `aggregate_array_identity_exposure_marks_materialization_hazard`, `indirect_array_alias_from_container_blocks_length_and_bounds_proofs`, `loop_local_array_alias_push_blocks_packed_f64_loop_and_artifacts`, `hir_facts` unit tests, and invalidation regressions in `crates/perry-codegen/tests/native_proof_regressions/invalidation.rs`. | +| `[~]` | Late boxing only at true dynamic boundaries | Native fast paths reduce boxing in verified regions; straight-line numeric and boolean ordinary-expression slices now materialize `f64`/`i1` only at return/runtime compatibility boundaries. Ordinary bodies still frequently lower to JSValue/`double` early outside those proven slices. | +| `[~]` | Treat async/generator lowering as allocation lowering | Compiler-private async/generator control locals now avoid generic JSValue boxes for the narrow closure-shared control state: `__gen_state` / `__gen_pending_type` use typed `i32` heap cells, and `__gen_done` / `__gen_executing` use typed boolean heap cells. This preserves closure lifetime/sharing semantics while keeping control reads, writes, and `__gen_state === const` dispatch comparisons in native `i32`/`i1`. Await payloads, `__gen_sent`, pending values, Promise resolution values, async captures, and externally visible async boundaries remain JSValue/generic. Evidence: `compiler_private_async_control_cells_use_primitive_heap_boxes`, `artifact_records_compiler_private_async_control_cells`, `primitive_control_boxes_round_trip_and_reject_foreign_pointers`, `representation_lowering_helpers_have_lto_keepalive_anchors`, and `test_runtime_symbol_guard_roots_async_control_box_helpers`. | +| `[~]` | Typed internal function/method/closure paths plus generic trampolines | Ordinary functions now have conservative typed-f64 clones for straight-line numeric return bodies, a bounded typed-i1 clone path for fixed-arity boolean-only functions with straight-line boolean return bodies, a first numeric-predicate typed-i1 function shape whose internal clone takes `double` params and returns `i1`, and a first fixed-arity typed-string passthrough clone whose internal clone takes and returns raw string handles as `i64`. Eligible ordinary functions expose the original public symbol as a JSValue trampoline and move the generic implementation to an internal `__generic` body; same-module direct calls can target f64/i1/string clones when their arguments are proven and guarded. Exact own instance methods now use the same public-symbol wrapper shape for the narrower method-eligible boolean/numeric slices: runtime vtables register the public JSValue trampoline, typed clones stay internal, numeric-predicate method clones use `i1(double, ...)` internal signatures, and guarded direct compiled calls jump to the internal generic method body on typed-argument guard failure. Eligible local closures expose the original closure function pointer as a JSValue trampoline, keep the generic closure body under `__generic`, and keep typed clones internal; numeric-predicate closure clones use `i1(i64 closure, double, ...)` internal signatures, and no-capture string passthrough closure clones use `i64(i64 closure, i64 string...)` internal signatures with `js_nanbox_string` only at wrapper/direct-call boundaries. Typed closure clones now always receive `i64 %this_closure`; immutable f64/i1 capture slots are loaded through that handle and converted to native reps before body lowering. String methods, string operators, dynamic string call sites, string captures, mutable captures, boxed captures, `this`/`new.target` captures, dynamic closure values, and escaping/async closure shapes remain generic.

A first store-bearing shape, `arr[i] = arr[i] + number` / safe numeric RHS, now side-exits to the slow clone on store-guard failure instead of rejoining after boxed fallback. Release symbol guard coverage now roots/asserts the generated typed-feedback array helpers (`packed_f64_array_loop_guard`, numeric get/set guards, boxed fallbacks, numeric push, and companion array feedback helpers) so stale LTO/static archives fail before link. Dynamic fractional index fallback evidence now covers preserving the original runtime key for get/set and not truncating typed-array fractional numeric keys. Local alias mutation, length writes, unknown calls, materialization hazards, and unsafe store-then-read shapes still invalidate or reject the relevant cached-length/bounds/packed-f64 proofs. Broader effect summaries remain incomplete. Evidence: `packed_f64_loop_store_update_versions_with_side_exit`, packed-f64 invalidation regressions, `test_runtime_symbol_guard_roots_typed_feedback_array_helpers`, `typed_feedback_boxed_fallback_preserves_fractional_keys_for_array_like_receivers`, `typed_feedback_boxed_set_fallback_does_not_truncate_fractional_array_like_keys`, `dynamic_fractional_array_index`, and `scripts/check_runtime_symbols.sh target/release/libperry_runtime.a`. | +| `[~]` | Fixed/unboxed class field layout and direct typed field access | Raw numeric class-field fast paths exist for proven fields. Numeric consumers now use a raw-f64 class-field get path that keeps the guarded fast load as native `f64` and coerces only the boxed runtime fallback before the numeric merge. Raw numeric class-field get/set artifacts now carry explicit exact-declared-receiver, guarded class-id/keys, raw-f64 slot-array, and pointer-free bitmap notes; raw numeric stores also emit `WriteBarrierElided` evidence because the slot is proven non-pointer. Unknown receivers and computed/dynamic-shape class bodies do not claim raw slot access in their source function. General fixed mixed layouts and runtime pointer bitmaps are not complete. Evidence: `typed_feedback_guards_direct_class_field_specialization`, `artifact_records_raw_numeric_class_field_f64_fast_paths_and_fallback_reasons`, and `raw_numeric_class_field_rejects_unknown_or_dynamic_shape_receiver`. | +| `[~]` | Method/effect summaries for scalar replacement across simple method calls | Exact-receiver summaries exist for scalar-replaced class instances whose own method is fixed-arity and synchronous with either a numeric `return` over public numeric `this.field` reads/numeric params/arithmetic, or a boolean comparison predicate over that same numeric subset. This lets `new Point(...).sum()` and `new Point(...).isAbove(n)`-style calls inline against scalar field slots without heap allocation or method dispatch when arguments are proven in the current expression. Public `number`/`Int32` local arguments now use a guarded fast path: the fast branch checks `js_typed_f64_arg_guard`, unboxes with `js_typed_f64_arg_to_raw`, and the fallback materializes the scalar receiver before generic by-ID method dispatch. Unproven `any` arguments stay generic. Mutation/effect summaries, inherited/dynamic methods, field writes, `this` escape, accessors, dynamic property reads, nested/unknown calls, and broader non-numeric methods remain open. Evidence: `scalar_replaced_simple_method_call_inlines_summary_without_dispatch`, `artifact_records_scalar_replaced_method_summary_inline`, `scalar_replaced_boolean_method_predicate_inlines_without_dispatch_or_allocation`, `artifact_records_scalar_replaced_boolean_method_predicate_inline`, `scalar_method_boolean_predicate_rejects_mutation_call_accessor_and_dynamic_property`, `scalar_method_boolean_predicate_rejects_unproven_numeric_arguments`, and `scalar_method_boolean_predicate_guards_public_numeric_arguments`. | +| `[~]` | Interned property/method ID dispatch for hot static names | A first compatibility ID layer routes selected generated static-name property get/set, method fallback/apply, typed-feedback method-call, and class-method bind callsites through `*_by_property_id` / `*_by_id` wrappers. The current ID representation is the interned heap `StringHeader` pointer emitted by the StringPool, preserving existing semantics while removing raw byte-pointer/length plumbing from those callsites. Full global numeric IDs, vtable/property maps keyed directly by IDs, dynamic/computed keys, JS bridge calls, and broad specialized paths remain open. Evidence: `static_property_access_on_computed_class_uses_property_id_wrappers`, `static_name_method_fallback_uses_method_id_wrapper`, `static_name_spread_method_fallback_uses_method_id_wrapper`, and `static_name_class_method_value_uses_method_id_bind_wrapper`. | +| `[~]` | Unified safe string-like lowering | A first `PerryStringRef` resolver normalizes raw interned `StringHeader*` IDs, boxed heap-string IDs, and boxed SSO short-string IDs for the by-ID property/method wrappers. The typed-string function and no-capture local-closure ABIs add a non-throwing string-only guard/unbox pair for JS string arguments and materialize SSO strings only after the guard. These still use raw `StringHeader*` handles for the internal clone, not a full end-to-end `PerryStringRef` value representation; string methods, string captures, string operators, and dynamic/computed lowering sites remain generic. Evidence: `dispatch_id_resolver_accepts_raw_heap_and_sso_string_forms`, `typed_string_arg_guard_is_non_throwing_and_string_only`, `typed_string_function_clone_emits_internal_clone_and_guarded_wrapper`, `artifact_records_typed_string_direct_call_selection`, `typed_string_closure_clone_emits_internal_clone_and_guarded_direct_call`, and `artifact_records_typed_string_closure_clone_selection`. | +| `[~]` | Key-specialized Map/Set lowering | Runtime Map/Set side tables already index numeric and string-content keys. Codegen now has a first static string-key collection slice: `Map.set/has` lowers through `js_map_set_string_number` / `js_map_has_string_key`, `Map.get` lowers through `js_map_get_string_key` while preserving boxed `JSValue`/`undefined` miss semantics, and `Set.add/has/delete` lowers through `js_set_add_string` / `js_set_has_string` / `js_set_delete_string` when the receiver type arguments and key/value expression are proven string. The generated-call helpers are rooted for release/LTO and covered by the runtime symbol guard. Numeric/int32 key specialization, unboxed stored values beyond the f64 map-set helper boundary, dynamic receivers, and broader `Record`/dictionary lowering remain generic. Evidence: `map_string_number_set_has_use_string_key_specialization`, `set_string_add_has_delete_use_string_specialization`, `string_number_specialized_helpers_use_string_content_keys`, `test_set_string_specialized_helpers_use_content_keys`, `representation_lowering_helpers_have_lto_keepalive_anchors`, and `test_runtime_symbol_guard_roots_map_set_string_lowering_helpers`. | +| `[~]` | User-facing `--explain-lowering` report | `perry build/compile --explain-lowering` emits a fresh `.perry-trace/lowering/.../explain-lowering.json` report and text summary from native-rep artifacts. The report now includes explicit reason maps and evidence rows for typed-clone selected/rejected/not-recorded decisions, generic fallbacks, dynamic boundaries, boxes, unboxes/coercions, runtime property gets, direct field loads, bounds kept/eliminated, and barriers emitted/eliminated. Explain-lowering mode requests comprehensive typed-clone rejection records from codegen, including broad clone-family mismatches that default native-rep artifact runs suppress for noise control. A bounded non-clone completeness slice now derives concrete categories for scalar-replaced raw-f64 direct field loads, generic write-barrier child-bit emissions, and checked-native bounds records that lack an explicit `bounds_state`. Other absent non-clone proof is still reported as `not_recorded`. Evidence: `cargo test -p perry lowering_report`, `report_derives_non_clone_reasons_without_explicit_reason_notes`, and `explain_lowering_mode_records_broad_typed_clone_rejection_reasons`. | + +## 0.1 Landed Scope for This Branch + +This branch landed selected native/region-local type lowering and has begun the +typed internal ABI work. It is not yet a general typed function, method, or +closure ABI. Public user function, method, and closure entry points still use +the generic `double`/NaN-box ABI for parameters and returns. Eligible ordinary +typed-f64/typed-i1 functions now expose that public ABI through a wrapper under +the original symbol, with an internal typed clone plus an internal generic body +fallback. The typed-i1 ordinary-function path includes a first mixed native +signature for numeric predicates: an internal `i1(double, ...)` clone is called +from the public JSValue wrapper after numeric guards, and same-module direct +`FuncRef` calls now carry typed parameter reps so they can guard/unbox `f64` +arguments and call that clone directly while keeping a generic body fallback. +A first typed-string ordinary-function path accepts fixed-arity string +parameters and a string passthrough return; its internal clone takes and returns +raw `StringHeader*` handles as `i64`, while the public wrapper guards/unboxes +JS string arguments, boxes the raw result with `js_nanbox_string`, and falls +back to the internal generic body on guard failure. Same-module direct +`FuncRef` calls with proven string arguments can guard/unbox and call the raw +string clone directly, boxing only at the call boundary. +Eligible own-instance methods use the same shape: the original method +symbol is a JSValue wrapper registered in runtime vtables, and the generic +method body moves to an internal `__generic` symbol. A narrow set of direct +compiled calls may still branch to the same internal typed-f64 or typed-i1 +function/method clones after guards pass, and those direct-call guard failures +target the generic body instead of re-entering the public wrapper. Eligible +local closures use the same wrapper/body split: the stored closure function +pointer remains the original public symbol, the generic closure body moves to +`__generic`, and internal raw-`double`/`i1` clones are called from the public +wrapper or guarded direct local closure call sites. Those typed closure clones +now take `i64 %this_closure` as their first internal parameter and can load +immutable typed capture slots as native f64/i1 values. The new native facts are +collected for module init, function, method, static-method, and closure bodies, +then consumed inside those bodies where a specific proof exists. Compiler evidence for this branch covers: -- region-local integer facts (`i32`/`u32`) and selected JS-number native reps; +- region-local integer facts (`i32`/`u32`), boolean facts (`i1`), and selected + JS-number native reps; - Buffer/Uint8Array `BufferView`/`U8` fast paths with explicit bounds and alias proof records; - packed-`f64` array loop versioning guarded by typed-feedback/runtime layout - checks; -- raw numeric class-field get/set paths guarded by layout and field facts; + checks, including the first safe store-update path whose store-guard failure + side-exits/restarts in the slow clone instead of rejoining the raw fast clone; +- a narrow representation-first ordinary-expression path for simple numeric + literals, locals, local assignment, and numeric binary ops, plus simple + boolean literals, locals, local assignment, numeric/boolean comparisons, and + unary `!`.

20:26:48 +0200 Subject: [PATCH 13/20] fix(codegen,ci): drop redundant init-string write barrier; allowlist type-lowering files MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit PR #5466 gate fixes (the type-lowering branch failed its own evidence gate, unenforced on the codex branch; main enforces it): - string_pool.rs: module string-handle init used emit_root_nanbox_store_on_block, emitting a js_write_barrier_root_nanbox per interned string. The slot is registered as a permanent global root on the next line (always scanned), so the remembered-set barrier is redundant; no allocation runs in the gap. Replaced with a plain store. This is what the native-region-proof write_barriers_static budgets (image_convolution=0, loop_data_dependent=1) always expected — the barriers were one-time init noise, never the hot path. image_convolution 5->0, loop_data_dependent 6->0. The branch's own analyzer counts root_nanbox barriers; main's didn't, which is why this only surfaced on the PR to main. - check_file_size.sh: allowlist the 7 type-lowering files already over the 2000-line cap (loops.rs, hir_facts.rs, map.rs, set.rs, typed_feedback.rs, typed_feedback/tests.rs, lowering_report.rs) — pre-existing on the branch (lint was unenforced there). Topical splits are reasonable follow-ups. Validation: native-region-proof gate EXIT 0 (all 11 workloads pass, 3 runs); check_file_size.sh OK; perry-codegen full suite green (incl. shadow_slot_hygiene).

Gated on `is_number()` so NaN-boxed tagged values (objects/strings/bigints) keep their payloads. - property_get.rs: strip the NaN-box POINTER_TAG before passing the receiver to `js_object_get_field_by_property_id_f64` (it takes a raw `*ObjectHeader`). GC write barriers (mirror the established LocalSet path): - array_push.rs: barrier after the bits-based box/closure-capture write-backs that store the realloc'd array head. - literals_vars.rs: barrier after the boxed-assignment and `++`/`--` box/ closure write-backs (BigInt `++` yields a heap pointer). Graceful fallback (PR #5464 follow-up): - index_set.rs: a packed-U32 loop store fact now falls through to the generic array-store path instead of aborting codegen via `bail!`. Benchmark: - h1_buffer_alias_negative.ts: the closureCapture hot loop now reads through the captured `read` closure so the alias-negative scenario is exercised. Skipped as false positives (verified against current code): the per-type typed-function/closure param-rep registries CodeRabbit suggested don't exist (`typed_i1_*_param_reps` is a shared registry keyed by id, populated for all clone kinds; the set-gate selects the clone), and the LoweredValue "partial move" finding doesn't apply (the match arms are unit patterns, no binding — the crate compiles).

That f64 was used by the guard only for an `is_plain_number` check that is tautological — every emit site supplies a statically-proven non-negative i32 index (proven via `numeric_index_has_integer_array_index_proof` or a bounded loop counter). Change the two guards to take the i32 index directly (no f64 `index_value`, no `is_plain_number` check) and materialize the f64 index lazily inside the (cold) boxed-fallback block, where it is actually needed. The proven-i32 callers now lower the index via `lower_expr_as_i32` instead of `fptosi(lower_expr(..))`, so no conversion is emitted in the hot region at all. Guard names are unchanged, so the evidence-gate allowlists and IR contains/regex checks still match. native-region-proof suite is now fully green (was: loop_data_dependent fail); runtime typed_feedback tests, perry-codegen tests, and the test_compiler_output_regression / test_native_abi_evidence_report harnesses all pass.

That overwrote the capture slot, which holds the BOX pointer, with the array pointer. The next push then read the array as if it were the box (`js_box_get_bits(array)`), so the real box never received the second realloc and the pushed element was lost (`parts.length` came back 1 instead of 2). Return after the box write-back in the captured/slot sub-branches so the capture slot keeps pointing at the box.
