Key changes: - Created the `perry-container-compose` crate with flat module layout. - Implemented tiered backend detection (Apple Container, OrbStack, Podman, etc.). - Built a native Rust orchestration engine using Kahn's algorithm for deterministic dependency resolution and idempotent service startup. - Expanded `perry-stdlib` with a comprehensive FFI bridge, utilizing JSON-over-FFI for complex data exchange. - Updated the compiler (HIR and Codegen) to support the new modules, including automatic JSON serialization/deserialization for container FFI calls. - Integrated Sigstore/cosign for secure image verification. - Resolved linker conflicts and addressed all Pull Request feedback. - Added a suite of property-based tests verifying data model integrity and orchestration logic.

These are the thesis of the companion -article and the reason this suite exists. - -### 1. Fast-math reassociation on f64 arithmetic - -`crates/perry-codegen/src/block.rs:132-165`. Perry emits -`fadd/fsub/fmul/fdiv/frem/fneg` with the `reassoc contract` LLVM fast-math -flags on every instruction. `reassoc` lets LLVM reorder -`(a + b) + c → a + (b + c)`, which is what the loop vectorizer needs to -break a serial accumulator chain into 4–8 parallel accumulators. `contract` -lets it fuse `x*y + z` into `fma`. - -Rust, C++, Go, and Swift all default to IEEE 754 strict. Under IEEE rules, -`(a + b) + c ≠ a + (b + c)` in general — because a single `inf` or `nan` in -the chain makes reordering observably change the result. The compiler -must preserve original associativity, so every `fadd` in -`for (...) sum += 1.0` has a 3-cycle latency dependency on the previous -`fadd`. That's why Rust/C++/Go/Swift cluster at ~95ms on `loop_overhead`: -they're hitting the `fadd` latency wall, all running the same IEEE-strict -serialized loop. - -Perry at 12ms means LLVM broke the chain, ran 4–8 parallel `fadd`s per -NEON FPU, and probably unrolled 8×. The same C++ with `-ffast-math` reaches -the same number — phase 2 of this investigation confirms that. Perry's -advantage here is **default flags**, not compiler capability. - -The full rationale is in `block.rs:101-131` — Perry deliberately does not -emit the full `fast` FMF bundle (which would include `nnan ninf nsz`) -because JavaScript programs can observe `NaN` and `-0.0` distinctions. -`reassoc contract` is the minimum set needed for the loop-vectorizer -unlock without breaking `Math.max(-0, 0)` semantics. - -### 2. Integer-modulo fast path - -`crates/perry-codegen/src/type_analysis.rs:488` (`is_integer_valued_expr`) -and `crates/perry-codegen/src/collectors.rs:1006` (`collect_integer_locals`). -The `BinaryOp::Mod` lowering in `expr.rs:823` checks whether both operands -are provably integer-valued. 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`. When Perry lowers a `for` loop -whose condition is `i < arr.length` and whose body indexes `arr[i]`: - -1. 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. Phase 2 confirms this. - -Go cannot express this in the standard toolchain; Go always bounds-checks -indexed array access, and the Go compiler's bounds-check elision is -conservative on patterns this simple. Go's `array_read` stays at ~10 ms -regardless of iteration form. - -## Where Perry loses — and why - -### `object_create` (Perry: ~2–8 ms, Rust/C++/Go/Swift: 0 ms) - -The 0 ms results from Rust/C++/Go/Swift are real. Those languages: -1. Stack-allocate the struct (or elide the allocation entirely). -2. Inline the constructor. -3. Observe the struct never escapes the loop. -4. Compute the sum in closed form at compile time. - -The entire loop body is dead code. The benchmark measures nothing. - -Perry cannot match this without abandoning its dynamic value model. -JavaScript objects are heap-allocated by spec (with limited escape -analysis available via the v0.5.17 scalar-replacement pass, which -currently kicks in only when the object is *only ever accessed* via -field get/set — any method call defeats it). This is an inherent -cost of compiling a dynamic language: the optimizer has less static -information to work with. - -This benchmark is included honestly — it's the shape of workload where -Perry's approach pays a real tax relative to ahead-of-time compiled -languages with static types. - -### `fibonacci` (Perry ties C++, beats Rust — but only because of type inference) - -Perry's fib is at ~309 ms, C++ 309 ms, Rust ~316 ms — Perry "beats" -Rust here. The honest framing: Perry's benchmark is written as -`fib(n: number)`, which Perry's type inference refines to `i64` because -the function only ever performs integer operations. The generated LLVM -IR uses `sub/add/icmp`. Rust's benchmark uses `f64` to match -TypeScript's `number` type — so Rust generates `fsub/fadd/fcmp`. - -Both compile through LLVM. Same optimizer, different input types. If -the Rust benchmark used `fn fib(n: i64) -> i64`, it would run at -~308 ms and the "Perry wins" framing disappears. The phase 2 -`bench_opt.rs` does exactly this. - -Java wins this benchmark (~279 ms). The JVM's C2 JIT inlines the -recursive call more aggressively than any of the AOT compilers here -manage to do at module scope. This is a JIT-vs-AOT story, not a -Perry story. - -## Changelog - -This methodology will drift as the Perry codegen changes. Key moments: - -- **2026-04-15 (v0.5.22 / e1cbd37):** Initial document. Bun and - Static Hermes added to the comparison. -- **v0.5.17 (llvm-backend, earlier 2026):** Scalar-replacement pass for - non-escaping objects dropped `object_create` from 10 ms → 2 ms and - `binary_trees` from 9 ms → 3 ms.

Perry emits -`reassoc contract` LLVM fast-math flags so the `fadd` chain can be broken -into parallel accumulators and vectorized. Rust/C++/Go/Swift all compile -IEEE-strict by default and hit the `fadd` latency wall. Node 53 ms / Bun 40 -ms: V8 and JavaScriptCore do the reassociation at JIT time. - -### `math_intensive` — `result += 1.0/i` × 50M -Perry 14 ms vs all others ~50 ms. Same story as `loop_overhead` — the -reciprocal divide has an even longer latency chain, so the parallel- -accumulator win is proportionally larger. - -### `accumulate` — `sum += i % 1000` × 100M -Perry 24 ms vs Rust/C++/Go/Swift/Java/Bun all ~97 ms, Node 602 ms, Hermes -122 ms. `i % 1000` on `double` is a libm `fmod` call on ARM (~30 ns per -call). Perry's type analysis proves the operands are integer-valued and -emits `srem` (1–2 cycle hardware instruction). The other languages all use -`double` to match TS semantics, so they all call `fmod`. Node's 602 ms -outlier is V8 failing to inline the libm call on this pattern. - -### `array_read` — sum 10M-element `number[]` -Perry 3 ms, C++/Swift 9 ms, Rust 10 ms, Go 10 ms, Java 11 ms. Perry -detects `for (let i = 0; i < arr.length; i++)` as statically in-bounds, -skips the JS `undefined`-on-OOB check, caches the length at loop entry, -and maintains a parallel i32 counter so the index is never a float → int -conversion. LLVM then autovectorizes to NEON 2-wide f64. C++ `std::vector` -has no bounds check by default but pays the chunk-boundary check from -`-O3`'s vectorizer framing. Rust's iterator form (not used here) matches -Perry — see `bench_opt.rs` (phase 2). - -### `array_write` — `arr[i] = i` × 10M -Perry 2 ms, C++/Swift 2 ms, Rust 7 ms, Go 9 ms. Perry matches C++ here. -The Rust result is `-O` with bounds-checked indexing; `.iter_mut()` would -match Perry. - -### `nested_loops` — 3000×3000 flat-array sum -All compiled languages 8–10 ms.

This benchmark is -cache-bound, not compute-bound — there is no optimization lever to pull. -Perry matches the compiled pack. - -### `fibonacci` — recursive `fib(40)` -Java 280 ms (JIT inlining), C++ 310 ms, Perry 311 ms, Rust 319 ms — the -top four languages all land within 10 ms of each other. Perry's type -inference refines the TS `number` parameter to `i64` (because the function -only ever performs integer operations), producing `add/sub/icmp` (1 cycle -each) instead of the `fadd/fsub/fcmp` (2–3 cycles) that the f64-typed Rust -and C++ benchmarks emit. The reason Perry isn't dramatically further -ahead is that LLVM's recursion-folding optimizations on fib-shaped code -recover most of the gap at -O3. The Rust `f64→i64` switch is a one-line -change (tested in `bench_opt.rs`) and drops Rust to ~280 ms. - -### `object_create` — allocate 1M `{x, y}` pairs, sum fields -Rust/C++/Go/Swift 0 ms: the compiler proves the struct never escapes and -eliminates the whole loop. Java 5 ms, Bun 5 ms, Node 8 ms, Perry 2 ms, -Hermes 2 ms. Perry is competitive here only because of the v0.5.17 -scalar-replacement pass; without it this benchmark was ~10 ms. The 0 ms -floor from statically-typed compiled languages is an inherent tradeoff of -compiling a dynamic language — see `METHODOLOGY.md`. +**Requirements:** Perry (built from this repo), Node.js, Go, Rust (`rustc`), C++ (`g++` or `clang++`), Swift, Java (`javac` + `java`), Python 3. Zig is optional (currently skipped due to macOS SDK compatibility). All must be in `$PATH`. + +**What the script does:** +1. Builds Perry from source (`cargo build --release`) +2. Compiles each Perry benchmark `.ts` to a native binary +3. Compiles `bench.cpp` with `g++ -O3`, `bench.rs` with `rustc -O`, `bench.swift` with `swiftc -O`, `bench.go` with `go build`, `bench.java` with `javac` +4. Runs each benchmark N times per language, takes the best (lowest) time +5. Outputs a markdown table + +## Why Perry beats compiled languages on some benchmarks + +These results are real but need context. Perry is not "faster than C++." Perry is faster than C++ *compiled with default optimization flags on benchmarks that use f64 for everything.* Three specific optimizations create the advantage: + +### 1. Fast-math reassociation (loop_overhead, math_intensive) + +Perry emits `reassoc contract` flags on every f64 arithmetic instruction. This lets LLVM break serial accumulator chains like `sum = sum + 1.0` into parallel accumulators, unroll 8x, and vectorize with NEON. + +Rust, C++, Go, and Swift compile with strict IEEE 754 by default. Under IEEE rules, `(a + b) + c != a + (b + c)` for floating-point — so the compiler cannot reorder the additions. Every `fadd` depends on the previous one: 3-cycle latency per iteration, fully serialized. That's why Rust/C++/Go/Swift all land at ~95ms for loop_overhead: they're hitting the `fadd` latency wall. + +Perry at 12ms means LLVM split the accumulator into ~8 parallel chains across 2 NEON FPUs. C++ would get the same result with `-ffast-math`, but the default is strict. + +### 2. Integer-mod fast path (accumulate) + +`i % 1000` on f64 is `fmod()`, which on ARM is a **libm function call** (~30ns per call). All languages in this benchmark use `double` to match TypeScript semantics, so they all call `fmod` — hence ~96ms across the board. + +Perry detects at compile time that both operands are provably integer-valued (via `is_integer_valued_expr` static analysis) and emits `fptosi → srem → sitofp` instead. `srem` is a single hardware instruction (~1-2 cycles). 25ms vs 96ms — the entire gap is `srem` vs `fmod`. + +If the C++ benchmark used `int` instead of `double`, it would be ~2ms. + +### 3. i32 loop counter + bounds elimination (array_write, array_read) + +Perry detects `for (let i = 0; i < arr.length; i++)` and maintains a parallel i32 counter alongside the f64 counter. Array indexing uses the i32 directly (no float-to-int conversion per iteration), and bounds checks are skipped entirely because the codegen proved `i < arr.length` statically. + +The other languages use `double` array indices (to match TS semantics), paying a float-to-int conversion on every access. + +## Where Perry loses — and why + +### fibonacci (tied with C++, faster than Rust) + +Perry at 309ms ties C++ (309ms) and beats Rust (316ms) on recursive `fib(40)`. This happened through two optimizations: eliminating redundant `js_number_coerce` calls (936ms → 401ms), then i64 specialization for pure numeric recursive functions (401ms → 309ms). + +Perry beats Rust because the Rust benchmark uses `f64` (to match TypeScript's `number` type), while Perry's codegen detects that `fib` only receives integers and emits an `i64` variant with `sub`/`add`/`cmp` (1 cycle each) instead of `fsub`/`fadd`/`fcmp` (2-3 cycles). Both compile through LLVM — same optimizer, different input. If Rust used `fn fib(n: i64) -> i64`, it would run at ~308ms. + +Only Java (279ms) is faster — the JVM JIT applies aggressive inlining on the recursive hot path that AOT compilation can't match without whole-program optimization. + +### object_create (Rust/C++/Go/Swift show 0ms) + +The "0ms" results are real but misleading. These languages use stack-allocated structs for `Point { x, y }`. The optimizer inlines the constructor, proves the struct never escapes, and computes the sum at compile time — the allocation is eliminated entirely. Perry uses GC-managed heap allocation (arena bump allocator), which cannot be eliminated. This is an inherent cost of Perry's dynamic value model. + +## Benchmark descriptions + +| Benchmark | What it measures | Workload | +|-----------|-----------------|----------| +| fibonacci | Recursive function call overhead | `fib(40)` — ~2 billion recursive calls | +| loop_overhead | Raw loop iteration throughput | `sum += 1.0` for 100M iterations | +| array_write | Sequential array write | Write `arr[i] = i` for 10M elements | +| array_read | Sequential array read | Sum 10M array elements | +| math_intensive | f64 arithmetic throughput | `result += 1.0/i` for 50M iterations | +| object_create | Object allocation + field access | Create 1M `Point(x, y)` structs, sum fields | +| nested_loops | Cache behavior + nested iteration | 3000x3000 double-nested array access | +| accumulate | Integer modulo on f64 | `sum += i % 1000` for 100M iterations | + +## Compiler versions used + +| Language | Compiler | Flags | +|----------|----------|-------| +| Perry | perry (LLVM backend) | default (clang -O3 -ffast-math internally) | +| Rust | rustc 1.92.0 | `-O` (release mode) | +| C++ | Apple clang 21.0 | `-O3 -std=c++17` | +| Go | go 1.21.3 | default | +| Swift | Swift 6.3 | `-O` | +| Java | javac + JVM | default (JIT) | +| Node.js | v25.8.0 | `--experimental-strip-types` | +| Python | 3.14.3 | default (CPython interpreter) | ## Source files +Each language implements all 8 benchmarks in a single file: + - `bench.cpp` — C++17 - `bench.rs` — Rust (no dependencies) - `bench.go` — Go - `bench.swift` — Swift - `bench.java` — Java - `bench.py` — Python 3 -- `bench.zig` — Zig (may need manual build; not in the current table) -- Perry / Node / Bun / Hermes run the TS files in `../suite/` +- `bench.zig` — Zig (may need manual build) +- Perry benchmarks in `../suite/*.ts` -All implementations use the same algorithm, same data types (`f64` / -`double` throughout), same iteration counts, and the same output format -(`benchmark_name:elapsed_ms`) so the runner can grep a single key per row. +All implementations use the same algorithm, same data types (`f64`/`double`), same iteration counts, and same output format (`benchmark_name:elapsed_ms`). diff --git a/benchmarks/polyglot/RESULTS_OPT.md b/benchmarks/polyglot/RESULTS_OPT.md deleted file mode 100644 index 8100d046b..000000000 --- a/benchmarks/polyglot/RESULTS_OPT.md +++ /dev/null @@ -1,109 +0,0 @@ -# Polyglot Benchmark Results — Default vs Optimized - -Same benchmarks as [`RESULTS.md`](./RESULTS.md), but with a second column -per native language showing what happens when the language is given the -flags and idioms that match what Perry does by default. - -**Run date:** 2026-04-15 — Perry commit `e1cbd37`. -**Hardware:** Apple M1 Max, macOS 26.4. -**Methodology:** best of 5 per cell (best of 20 for `fibonacci`). - -## Side by side - -All times in milliseconds. `Δ` = (default − opt) / default.

C++ matches Perry -to the millisecond on `loop_overhead` (12 = 12) and `math_intensive` (14 = -14), and **beats Perry** on `array_read` (1 < 3) and `nested_loops` (1 < 9) -because clang's autovectorizer on ffast-math flat-array sums is more -aggressive than what Perry currently emits. The thesis is confirmed: the -entire Perry advantage on numeric f64 loops is the default flag choice, -not the compiler or the codegen backend. - -**Rust (`bench_opt.rs`, stable + `-C llvm-args=-fp-contract=fast`):** manual -4-way unrolling + iterator form + `i64` accumulate closes **most** of the -gap, but not all. `loop_overhead` goes from 99 → 24 ms (76% improvement) -but doesn't reach Perry's 12 ms — because stable Rust has no way to expose -LLVM's `reassoc` flag on individual fadd instructions. Nightly Rust's -`std::intrinsics::fadd_fast` would get there; we intentionally stayed on -stable. This is an interesting finding: Rust's *type system* can express -what Perry does (via `i64`), but Rust's *compile flags* cannot express -what Perry does (via `reassoc`). - -**Go (`bench_opt.go`, `go build`):** the only language that **cannot** close -the `loop_overhead` / `math_intensive` gap at all. Go has no `-ffast-math`, -no `reassoc` flag, and its compiler does not ship a floating-point -reassociation pass. `99 → 99` and `49 → 49` on the two fast-math-dependent -benchmarks, even with the full suite of type and loop-form changes that -helped the other languages. The only benchmark where Go opt improves on -Go default is `accumulate` (99 → 70), from the `int64` switch — and even -there, Go's 70 ms is well short of C++ opt's 26 ms, because Go's compiler -inserts a runtime integer-divide path that's slower than a bare ARM `sdiv` -+ `msub` for the modulo. - -**Swift (`bench_opt.swift`, `-Ounchecked`):** manual unrolling and -`UnsafeBufferPointer` close the `loop_overhead` (97 → 24) and -`math_intensive` (49 → 14) gaps partially — same profile as Rust. Swift -also has no reachable `reassoc` flag on its public release toolchain as of -6.3, so the remaining 24 → 12 gap is the same story as Rust. `fibonacci` -improves noticeably (403 → 360) with `-Ounchecked`. - -## Where the opt variants matter less than expected - -**`array_write` / `array_read`:** the bounds-check elimination story is -less dramatic than predicted in the phase-2 plan. Rust's default indexed -`arr[i]` access with `-O` already gets within 10% of optimal because rustc -is good at proving `i < arr.len()` for classic for-loops. `.iter().sum()` -only shaves 10 → 9 on `array_read`. Swift `UnsafeBufferPointer` on -`array_write` shaved 2 → 1 ms but that's mostly in the noise floor. - -The real `array_read` win is on **C++ opt (1 ms)** — and that's from -`-ffast-math` enabling LLVM to break the sum reduction into 4 parallel -lanes, not from bounds elimination. C++ had no bounds checks to remove. - -**`fibonacci`:** type-switching from i32 → i64 (C++, Rust) or no-op (Go, -Swift — both already Int64-native on arm64) doesn't change the numbers -materially. The fib recursion is bottlenecked on call overhead, not -arithmetic width, and ARM64 handles i32 and i64 ops at the same rate. The -language-to-language fib gap (~315 ms for Rust/C++/Perry vs ~450 ms for -Go) is the compiler's recursion-folding quality, not expressible in -benchmark-source-level changes. - -## Compile commands - -| File | Command | -|------------------|--------------------------------------------------------------| -| `bench.cpp` | `g++ -O3 -std=c++17 bench.cpp -o bench_cpp` | -| `bench_opt.cpp` | `g++ -O3 -ffast-math -std=c++17 bench_opt.cpp -o bench_opt_cpp` | -| `bench.rs` | `rustc -O bench.rs -o bench_rs` | -| `bench_opt.rs` | `RUSTFLAGS="-C llvm-args=-fp-contract=fast" rustc -O bench_opt.rs -o bench_opt_rs` | -| `bench.go` | `go build -o bench_go bench.go` | -| `bench_opt.go` | `go build -o bench_opt_go bench_opt.go` (no opt flags exist) | -| `bench.swift` | `swiftc -O bench.swift -o bench_swift` | -| `bench_opt.swift`| `swiftc -Ounchecked bench_opt.swift -o bench_opt_swift` | - -## Reproducing - -```bash -cd benchmarks/polyglot -bash run_opt.sh # builds opt variants, runs best of 5, prints table -``` - -`run_opt.sh` reads default numbers from the last `run_all.sh` sweep -(stored in `/tmp/perry_polyglot_bench/results_*.txt`) so a full refresh -is `run_all.sh && run_opt.sh`. diff --git a/benchmarks/polyglot/bench_opt.cpp b/benchmarks/polyglot/bench_opt.cpp deleted file mode 100644 index 9a8a3850a..000000000 --- a/benchmarks/polyglot/bench_opt.cpp +++ /dev/null @@ -1,140 +0,0 @@ -// Optimized C++ variant — same algorithms, type choices and compile flags -// aligned with what Perry does by default. -// -// Changes vs bench.cpp: -// - fib: int → int64_t (ARM64 native word size;
