From: Henry Gressmann Date: Fri, 28 Jun 2024 01:10:54 +0200 Subject: [PATCH 22/39] feat: compact value stack (#21) Not fully done, but ready for the `next` branch now. This changes how values are represented internally, making this pr particularly large, as this touches most parts of the codebase. The parser should now also be ready for multithreaded compilation to speed this up a bit. --------- Signed-off-by: Henry Gressmann --- CHANGELOG.md | 9 + Cargo.lock | 28 +- crates/cli/Cargo.toml | 2 +- crates/parser/Cargo.toml | 2 +- crates/parser/src/conversion.rs | 48 +- crates/parser/src/lib.rs | 1 + crates/parser/src/module.rs | 11 +- crates/parser/src/visit.rs | 217 ++--- crates/tinywasm/Cargo.toml | 12 +- crates/tinywasm/src/boxvec.rs | 148 ---- crates/tinywasm/src/func.rs | 13 +- crates/tinywasm/src/lib.rs | 1 - .../src/runtime/interpreter/macros.rs | 131 --- .../tinywasm/src/runtime/interpreter/mod.rs | 768 +++++++++--------- .../interpreter/{traits.rs => num_helpers.rs} | 44 + crates/tinywasm/src/runtime/mod.rs | 16 +- crates/tinywasm/src/runtime/raw.rs | 123 --- crates/tinywasm/src/runtime/raw_simd.rs | 27 - .../tinywasm/src/runtime/stack/block_stack.rs | 15 +- .../tinywasm/src/runtime/stack/call_stack.rs | 81 +- crates/tinywasm/src/runtime/stack/mod.rs | 3 +- .../tinywasm/src/runtime/stack/value_stack.rs | 291 +++---- crates/tinywasm/src/runtime/stack/values.rs | 420 ++++++++++ crates/tinywasm/src/store/global.rs | 8 +- crates/tinywasm/src/store/mod.rs | 38 +- crates/tinywasm/tests/generated/2.0.csv | 2 +- crates/types/src/instructions.rs | 66 +- crates/types/src/lib.rs | 11 +- 28 files changed, 1302 insertions(+), 1234 deletions(-) delete mode 100644 crates/tinywasm/src/boxvec.rs delete mode 100644 crates/tinywasm/src/runtime/interpreter/macros.rs rename crates/tinywasm/src/runtime/interpreter/{traits.rs => num_helpers.rs} (66%) delete mode 100644 crates/tinywasm/src/runtime/raw.rs delete mode 100644 crates/tinywasm/src/runtime/raw_simd.rs create mode 100644 crates/tinywasm/src/runtime/stack/values.rs diff --git a/CHANGELOG.md b/CHANGELOG.md index f6539a1..da8359c 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -5,6 +5,15 @@ All notable changes to this project will be documented in this file.

-> Note that parsing is still pretty slow, especially for the `selfhosted` benchmark, taking up `~6ms` for TinyWasm. -> This can be improved by using the `archive` feature, which pre-compiles the WebAssembly file into tinywasm's internal bytecode format. - -### Fib - -The first benchmark is a simple optimized Fibonacci function, a good way to show the overhead of calling functions and parsing the bytecode. -TinyWasm is slightly faster than Wasmi here, but that's probably because of the overhead of parsing the bytecode, as TinyWasm uses a custom bytecode to pre-process the WebAssembly bytecode. - -### Fib-Rec - -This benchmark is a recursive Fibonacci function, highlighting some issues with the current implementation of TinyWasm's Call Stack. -TinyWasm is a lot slower here, but that's because there's currently no way to reuse the same Call Frame for recursive calls, so a new Call Frame is allocated for every call. This is not a problem for most programs; the upcoming `tail-call` proposal will make this much easier to implement. - -### Argon2id - -This benchmark runs the Argon2id hashing algorithm with 2 iterations, 1KB of memory, and 1 parallel lane. -I had to decrease the memory usage from the default to 1KB because the interpreters were struggling to finish in a reasonable amount of time. -This is where `simd` instructions would be really useful, and it also highlights some of the issues with the current implementation of TinyWasm's Value Stack and Memory Instances. These spend much time on stack operations, so they might be a good place to experiment with Arena Allocation. - -### Selfhosted - -This benchmark runs TinyWasm itself in the VM, and parses and executes the `print.wasm` example from the `examples` folder. -This is a good way to show some of TinyWasm's strengths - the code is quite large at 702KB and Wasmer struggles massively with it, even with the Single Pass compiler. I think it's a decent real-world performance benchmark, but it definitely favors TinyWasm a bit. - -Wasmer also offers a pre-parsed module format, so keep in mind that this number could be a bit lower if that was used (but probably still on the same order of magnitude). This number seems so high that I'm not sure if I'm doing something wrong, so I will be looking into this in the future. - -### Conclusion - -After profiling and fixing some low-hanging fruits, I found the biggest bottleneck to be Vector operations, especially for the Value Stack, and having shared access to Memory Instances using RefCell. These are the two areas I will focus on improving in the future, trying out Arena Allocation and other data structures to improve performance. Additionally, typed FuncHandles have a significant overhead over the untyped ones, so I will also look into improving that. Still, I'm pretty happy with the results, especially considering the focus on simplicity and portability over performance. - -Something that made a much more significant difference than I expected was to give compiler hints about cold paths and to force the inlining of some functions. This made the benchmarks 30%+ faster in some cases.

This enables TinyWasm to run most WebAssembly programs, including executing TinyWasm itself compiled to WebAssembly (see [examples/wasm-rust.rs](./examples/wasm-rust.rs)). The results of the testsuites are available [here](https://github.com/explodingcamera/tinywasm/tree/main/crates/tinywasm/tests/generated). -The API is still unstable and may change at any time, so you probably don't want to use it in production _yet_.

More details on its performance can be found in [BENCHMARKS.md](./BENCHMARKS.md). +The API is still unstable and may change at any time, so you probably don't want to use it in production _yet_. TinyWasm isn't primarily designed for high performance; it focuses more on simplicity, size, and portability. Benchmarks are currently being reworked and will be available again soon. **Future Development**: The first major version will focus on improving the API and adding support for [WASI](https://wasi.dev/). While doing so, I also want to further simplify and reduce the codebase's size and improve the parser's performance. diff --git a/benchmarks/Cargo.toml b/benchmarks/Cargo.toml deleted file mode 100644 index 516767e..0000000 --- a/benchmarks/Cargo.toml +++ /dev/null @@ -1,25 +0,0 @@ -[package] -name="benchmarks" -publish=false -edition.workspace=true -rust-version.workspace=true - -[dependencies] -criterion={version="0.5"} -tinywasm={path="../crates/tinywasm"} -wat={version="1"} -wasmi={version="0.33", features=["std"]} -wasmer={version="4.3", features=["cranelift", "singlepass"]} -argon2={version="0.5"} - -[[bench]] -name="selfhosted" -harness=false - -[[bench]] -name="fibonacci" -harness=false - -[[bench]] -name="argon2id" -harness=false diff --git a/benchmarks/benches/argon2id.rs b/benchmarks/benches/argon2id.rs deleted file mode 100644 index 92250b8..0000000 --- a/benchmarks/benches/argon2id.rs +++ /dev/null @@ -1,58 +0,0 @@ -mod util; -use criterion::{black_box, criterion_group, criterion_main, Criterion}; - -fn run_tinywasm(wasm: &[u8], params: (i32, i32, i32), name: &str) { - let (mut store, instance) = util::tinywasm(wasm); - let argon2 = instance.exported_func::<(i32, i32, i32), i32>(&store, name).expect("exported_func"); - argon2.call(&mut store, params).expect("call"); -} - -fn run_wasmi(wasm: &[u8], params: (i32, i32, i32), name: &str) { - let (module, mut store, linker) = util::wasmi(wasm); - let instance = linker.instantiate(&mut store, &module).expect("instantiate").start(&mut store).expect("start"); - let argon2 = instance.get_typed_func::<(i32, i32, i32), i32>(&mut store, name).expect("get_typed_func"); - argon2.call(&mut store, params).expect("call"); -} - -fn run_wasmer(wasm: &[u8], params: (i32, i32, i32), name: &str) { - use wasmer::Value; - let (mut store, instance) = util::wasmer(wasm); - let argon2 = instance.exports.get_function(name).expect("get_function"); - argon2.call(&mut store, &[Value::I32(params.0), Value::I32(params.1), Value::I32(params.2)]).expect("call"); -} - -fn run_native(params: (i32, i32, i32)) { - fn run_native(m_cost: i32, t_cost: i32, p_cost: i32) { - let password = b"password"; - let salt = b"some random salt"; - - let params = argon2::Params::new(m_cost as u32, t_cost as u32, p_cost as u32, None).unwrap(); - let argon = argon2::Argon2::new(argon2::Algorithm::Argon2id, argon2::Version::V0x13, params); - - let mut hash = [0u8; 32]; - argon.hash_password_into(password, salt, &mut hash).unwrap(); - } - run_native(params.0, params.1, params.2) -} - -static ARGON2ID: &[u8] = include_bytes!("../../examples/rust/out/argon2id.opt.wasm"); -fn criterion_benchmark(c: &mut Criterion) { - let params = (1000, 2, 1); - - let mut group = c.benchmark_group("argon2id"); - group.measurement_time(std::time::Duration::from_secs(7)); - group.sample_size(10); - - group.bench_function("native", |b| b.iter(|| run_native(black_box(params)))); - group.bench_function("tinywasm", |b| b.iter(|| run_tinywasm(ARGON2ID, black_box(params), "argon2id"))); - group.bench_function("wasmi", |b| b.iter(|| run_wasmi(ARGON2ID, black_box(params), "argon2id"))); - group.bench_function("wasmer", |b| b.iter(|| run_wasmer(ARGON2ID, black_box(params), "argon2id"))); -} - -criterion_group!( - name = benches; - config = Criterion::default().significance_level(0.1); - targets = criterion_benchmark -); - -criterion_main!(benches); diff --git a/benchmarks/benches/fibonacci.rs b/benchmarks/benches/fibonacci.rs deleted file mode 100644 index b1ece55..0000000 --- a/benchmarks/benches/fibonacci.rs +++ /dev/null @@ -1,75 +0,0 @@ -mod util; -use criterion::{black_box, criterion_group, criterion_main, Criterion}; - -fn run_tinywasm(wasm: &[u8], iterations: i32, name: &str) { - let (mut store, instance) = util::tinywasm(wasm); - let fib = instance.exported_func::(&store, name).expect("exported_func"); - fib.call(&mut store, iterations).expect("call"); -} - -fn run_wasmi(wasm: &[u8], iterations: i32, name: &str) { - let (module, mut store, linker) = util::wasmi(wasm); - let instance = linker.instantiate(&mut store, &module).expect("instantiate").start(&mut store).expect("start"); - let fib = instance.get_typed_func::(&mut store, name).expect("get_typed_func"); - fib.call(&mut store, iterations).expect("call"); -} - -fn run_wasmer(wasm: &[u8], iterations: i32, name: &str) { - use wasmer::*; - let compiler = wasmer::Singlepass::default(); - let mut store = Store::new(compiler); - let import_object = imports!

(`rkyv` which uses unsafe code can be used for serialization, but is optional). ## Status -As of version `0.3.0`, TinyWasm successfully passes all the WebAssembly 1.0 tests in the [WebAssembly Test Suite](https://github.com/WebAssembly/testsuite). Work on the 2.0 tests is ongoing. This enables TinyWasm to run most WebAssembly programs, including executing TinyWasm itself compiled to WebAssembly (see [examples/wasm-rust.rs](./examples/wasm-rust.rs)). The results of the testsuites are available [here](https://github.com/explodingcamera/tinywasm/tree/main/crates/tinywasm/tests/generated). - -The API is still unstable and may change at any time, so you probably don't want to use it in production _yet_. TinyWasm isn't primarily designed for high performance; it focuses more on simplicity, size, and portability. Benchmarks are currently being reworked and will be available again soon. - -**Future Development**: The first major version will focus on improving the API and adding support for [WASI](https://wasi.dev/). While doing so, I also want to further simplify and reduce the codebase's size and improve the parser's performance. +TinyWasm passes all WebAssembly MVP tests from the [WebAssembly core testsuite](https://github.com/WebAssembly/testsuite) and is able to run most WebAssembly programs. Additionally, the current 2.0 Draft is mostly supported, with the exception of Fixed-Width SIMD and Memory64/Multiple Memories.
