Specification](https://webassembly.github.io/spec/core/exec/runtime.html). +Some key differences are: + +- Values are stored without their type, (as `u64`), and the type is inferred from the instruction that uses them. This is possible because the instructions are validated before execution and the type of each value can be inferred from the instruction. +- TinyWasm has a explicit stack for values, labels and frames. This is mostly for simplicity in the implementation, but also allows for some optimizations. +- Floats always use a canonical NaN representation, the spec allows for multiple NaN representations. +- TinyWasm uses a custom bytecode format (see [Bytecode Format](#bytecode-format) for more details) +- Global state in the `Store` can be addressed from module instances other than the owning module. This is to allow more efficient access to imports and exports. Ownership is still enforced implicitly by requiring a reference to the instance to access it which can not be changed using the WebAssembly instructions. +- The `Store` is not thread-safe. This is to allow for more efficient access to the `Store` and its contents. When later adding support for threads, a `Mutex` can be used to make it thread-safe but the overhead of requiring a lock for every access is not necessary for single-threaded applications. +- TinyWasm is architectured to allow for a JIT compiler to be added later. Functions are stored as FunctionInstances which can contain either a `WasmFunction` or a `HostFunction`. A third variant `JitFunction` could be added later to store a pointer to the compiled function. This would allow for the JIT to be used transparently without changing the rest of the runtime. +- TinyWasm is designed to be used in `no_std` environments. The `std` feature is enabled by default, but can be disabled to remove the dependency on `std` and `std::io`. This is done by disabling the `std` and `parser` features. The `logging` feature can also be disabled to remove the dependency on `log`. This is not recommended, since `libm` is not as performant as the compiler's math intrinsics, especially on wasm32 targets, but can be useful for resource-constrained devices or other environments where `std` is not available such as OS kernels. +- Call Frames are executed in a loop instead of recursively. This allows the use of a single stack for all frames and makes it easier to pause execution and resume it later, or to step through the code one instruction at a time. + +## Bytecode Format + +To improve performance and reduce code size, instructions are encoded as enum variants instead of opcodes. +This allows preprocessing the bytecode into a more compact format, which can be loaded directly into memory and executed without decoding later. This can skip the decoding step entirely on resource-constrained devices where memory is limited. + +Some instructions are split into multiple variants to reduce the size of the enum (e.g. `br_table` and `br_label`). +Additionally, label instructions contain offsets relative to the current instruction to make branching faster and easier to implement. +Also, `End` instructions are split into `End` and `EndBlock`. + +See [instructions.rs](./crates/types/src/instructions.rs) for the full list of instructions. + +This is a area that can still be improved. While being able to load pre-processes bytecode directly into memory is nice, in-place decoding could achieve similar speeds, see [A fast in-place interpreter for WebAssembly](https://arxiv.org/abs/2205.01183). diff --git a/README.md b/README.md index 57728a4..9fd38ca 100644 --- a/README.md +++ b/README.md @@ -5,7 +5,7 @@

Functions are stored as FunctionInstances which can contain either a `WasmFunction` or a `HostFunction`. A third variant `JitFunction` could be added later to store a pointer to the compiled function. This would allow for the JIT to be used transparently without changing the rest of the runtime. - TinyWasm is designed to be used in `no_std` environments. The `std` feature is enabled by default, but can be disabled to remove the dependency on `std` and `std::io`. This is done by disabling the `std` and `parser` features. The `logging` feature can also be disabled to remove the dependency on `log`. This is not recommended, since `libm` is not as performant as the compiler's math intrinsics, especially on wasm32 targets, but can be useful for resource-constrained devices or other environments where `std` is not available such as OS kernels. - Call Frames are executed in a loop instead of recursively. This allows the use of a single stack for all frames and makes it easier to pause execution and resume it later, or to step through the code one instruction at a time. +- While other interpreters convert `locals` to be register-based when parsing the function body, TinyWasm keeps them in a stack. This is mostly for simplicity in the implementation, but performance is still comparable or better than other interpreters. ## Bytecode Format diff --git a/README.md b/README.md index c899701..e7a66ae 100644 --- a/README.md +++ b/README.md @@ -5,11 +5,17 @@

These are the two areas I will be focusing on improving in the future, trying out to use +Arena Allocation and other data structures to improve performance. Still, I'm quite happy with the results, especially considering the use of standard Rust data structures. Additionally, typed FuncHandles have a significant overhead over the untyped ones, so I will be looking into improving that as well. + # Running benchmarks Benchmarks are run using [Criterion.rs](https://github.com/bheisler/criterion.rs).

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, and the upcoming `tail-call` proposal will make this a lot 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 especially 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. + ### Selfhosted This benchmark runs TinyWasm itself in the VM, and parses and executes the `print.wasm` example from the `examples` folder. -This is a godd way to show some of TinyWasm's strengths - the code is pretty 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.

Some key differences are: -- Values are stored without their type, (as `u64`), and the type is inferred from the instruction that uses them. This is possible because the instructions are validated before execution and the type of each value can be inferred from the instruction. -- TinyWasm has a explicit stack for values, labels and frames. This is mostly for simplicity in the implementation, but also allows for some optimizations. -- Floats always use a canonical NaN representation, the spec allows for multiple NaN representations. -- TinyWasm uses a custom bytecode format (see [Bytecode Format](#bytecode-format) for more details) -- Global state in the `Store` can be addressed from module instances other than the owning module. This is to allow more efficient access to imports and exports. Ownership is still enforced implicitly by requiring a reference to the instance to access it which can not be changed using the WebAssembly instructions. -- The `Store` is not thread-safe. This is to allow for more efficient access to the `Store` and its contents. When later adding support for threads, a `Mutex` can be used to make it thread-safe but the overhead of requiring a lock for every access is not necessary for single-threaded applications. -- TinyWasm is architectured to allow for a JIT compiler to be added later. Functions are stored as FunctionInstances which can contain either a `WasmFunction` or a `HostFunction`. A third variant `JitFunction` could be added later to store a pointer to the compiled function. This would allow for the JIT to be used transparently without changing the rest of the runtime. -- TinyWasm is designed to be used in `no_std` environments. The `std` feature is enabled by default, but can be disabled to remove the dependency on `std` and `std::io`. This is done by disabling the `std` and `parser` features. The `logging` feature can also be disabled to remove the dependency on `log`. This is not recommended, since `libm` is not as performant as the compiler's math intrinsics, especially on wasm32 targets, but can be useful for resource-constrained devices or other environments where `std` is not available such as OS kernels. -- Call Frames are executed in a loop instead of recursively. This allows the use of a single stack for all frames and makes it easier to pause execution and resume it later, or to step through the code one instruction at a time. -- While other interpreters convert `locals` to be register-based when parsing the function body, TinyWasm keeps them in a stack. This is mostly for simplicity in the implementation, but performance is still comparable or better than other interpreters. +- **Type Storage**: Types are inferred from usage context rather than stored explicitly, with all values held as `u64`. +- **Stack Design**: Implements a specific stack for values, labels, and frames to simplify the implementation and enable optimizations. +- **Bytecode Format**: Adopts a custom bytecode format to reduce memory usage and improve performance by allowing direct execution without the need for decoding. +- **Global State Access**: Allows cross-module access to the `Store`'s global state, optimizing imports and exports access. Access requires a module instance reference, maintaining implicit ownership through a reference count. +- **Non-thread-safe Store**: Designed for efficiency in single-threaded applications. +- **JIT Compilation Support**: Prepares for JIT compiler integration with function instances designed to accommodate `WasmFunction`, `HostFunction`, or future `JitFunction`. +- **`no_std` Environment Support**: Offers compatibility with `no_std` environments by allowing disabling of `std` feature +- **Call Frame Execution**: Executes call frames in a single loop rather than recursively, using a single stack for all frames, facilitating easier pause, resume, and step-through. ## Bytecode Format To improve performance and reduce code size, instructions are encoded as enum variants instead of opcodes. -This allows preprocessing the bytecode into a more compact format, which can be loaded directly into memory and executed without decoding later.

From: Henry Gressmann Date: Fri, 28 Jun 2024 01:10:54 +0200 Subject: [PATCH 098/115] 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.
