Most `Default` impls are trivial, which should in theory allow LLVM to construct `T: Default` directly in the `Box` allocation when calling `>::default()`. However, the allocation may fail, which necessitates calling `T's` destructor if it has one. If the destructor is non-trivial, then LLVM has a hard time proving that it's sound to elide, which makes it construct `T` on the stack first, and then copy it into the allocation. Create an uninit `Box` first, and then write `T::default` into it, so that LLVM now only needs to prove that the `T::default` can't panic, which should be trivial for most `Default` impls. --- library/alloc/src/boxed.rs | 2 +- tests/codegen/placement-new.rs | 4 ++-- 2 files changed, 3 insertions(+), 3 deletions(-) diff --git a/library/alloc/src/boxed.rs b/library/alloc/src/boxed.rs index 5f2072956835..3e791416820e 100644 --- a/library/alloc/src/boxed.rs +++ b/library/alloc/src/boxed.rs @@ -1688,7 +1688,7 @@ impl Default for Box { /// Creates a `Box`, with the `Default` value for T. #[inline] fn default() -> Self { - Box::new(T::default()) + Box::write(Box::new_uninit(), T::default()) } } diff --git a/tests/codegen/placement-new.rs b/tests/codegen/placement-new.rs index 68260a65a3f3..d5c7969dd19b 100644 --- a/tests/codegen/placement-new.rs +++ b/tests/codegen/placement-new.rs @@ -9,9 +9,9 @@ use std::sync::Arc; // CHECK-LABEL: @box_default_inplace #[no_mangle] pub fn box_default_inplace() -> Box<(String, String)> { - // CHECK: [[ALLOCA:%.*]] = alloca + // CHECK-NOT: alloca // CHECK: [[BOX:%.*]] = {{.*}}call {{.*}}__rust_alloc( - // CHECK: call void @llvm.memcpy{{.*}}(ptr {{.*}}[[BOX]], ptr {{.*}}[[ALLOCA]] + // CHECK-NOT: call void @llvm.memcpy // CHECK: ret ptr [[BOX]] Box::default() } From 5e474f7d83fc931f355cfdadf394313e57290050 Mon Sep 17 00:00:00 2001 From: Joshua Wong Date: Wed, 9 Oct 2024 14:24:05 -0400 Subject: [PATCH 025/118] allocate before calling T::default in >::default() Same rationale as in the previous commit. --- library/alloc/src/lib.rs | 1 + library/alloc/src/sync.rs | 8 +++++++- tests/codegen/placement-new.rs | 4 ++-- 3 files changed, 10 insertions(+), 3 deletions(-) diff --git a/library/alloc/src/lib.rs b/library/alloc/src/lib.rs index c60c0743c7e1..dcfe96be7551 100644 --- a/library/alloc/src/lib.rs +++ b/library/alloc/src/lib.rs @@ -104,6 +104,7 @@ #![feature(async_closure)] #![feature(async_fn_traits)] #![feature(async_iterator)] +#![feature(box_uninit_write)] #![feature(clone_to_uninit)] #![feature(coerce_unsized)] #![feature(const_align_of_val)] diff --git a/library/alloc/src/sync.rs b/library/alloc/src/sync.rs index 5d099a49854a..0038750d25dd 100644 --- a/library/alloc/src/sync.rs +++ b/library/alloc/src/sync.rs @@ -3447,7 +3447,13 @@ impl Default for Arc { /// assert_eq!(*x, 0); /// ``` fn default() -> Arc { - Arc::new(Default::default()) + let x = Box::into_raw(Box::write(Box::new_uninit(), ArcInner { + strong: atomic::AtomicUsize::new(1), + weak: atomic::AtomicUsize::new(1), + data: T::default(), + })); + // SAFETY: `Box::into_raw` consumes the `Box` and never returns null + unsafe { Self::from_inner(NonNull::new_unchecked(x)) } } } diff --git a/tests/codegen/placement-new.rs b/tests/codegen/placement-new.rs index d5c7969dd19b..edb25df5eb4d 100644 --- a/tests/codegen/placement-new.rs +++ b/tests/codegen/placement-new.rs @@ -19,9 +19,9 @@ pub fn box_default_inplace() -> Box<(String, String)> { // CHECK-LABEL: @arc_default_inplace #[no_mangle] pub fn arc_default_inplace() -> Arc<(String, String)> { - // CHECK: [[ALLOCA:%.*]] = alloca + // CHECK-NOT: alloca // CHECK: [[ARC:%.*]] = {{.*}}call {{.*}}__rust_alloc( - // CHECK: call void @llvm.memcpy + // CHECK-NOT: call void @llvm.memcpy // CHECK: ret ptr [[ARC]] Arc::default() } From 159e67d44646621f157f07b61f7d78f231c452c6 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Jonathan=20D=C3=B6nszelmann?= Date: Fri, 11 Oct 2024 00:14:17 +0200 Subject: [PATCH 026/118] rename RcBox to RcInner for consistency --- library/alloc/src/rc.rs | 138 +++++++++++++++++++++------------------- 1 file changed, 71 insertions(+), 67 deletions(-) diff --git a/library/alloc/src/rc.rs b/library/alloc/src/rc.rs index 0e2c35845e8f..e6f27f536399 100644 --- a/library/alloc/src/rc.rs +++ b/library/alloc/src/rc.rs @@ -282,19 +282,19 @@ mod tests; // would interfere with otherwise safe [into|from]_raw() of transmutable // inner types. #[repr(C)] -struct RcBox { +struct RcInner { strong: Cell, weak: Cell, value: T, } -/// Calculate layout for `RcBox` using the inner value's layout +/// Calculate layout for `RcInner` using the inner value's layout fn rcbox_layout_for_value_layout(layout: Layout) -> Layout { // Calculate layout using the given value layout. // Previously, layout was calculated on the expression - // `&*(ptr as *const RcBox)`, but this created a misaligned + // `&*(ptr as *const RcInner)`, but this created a misaligned // reference (see #54908). - Layout::new::>().extend(layout).unwrap().0.pad_to_align() + Layout::new::>().extend(layout).unwrap().0.pad_to_align() } /// A single-threaded reference-counting pointer.

If you have `{-1:int}` it means int's everywhere, +//! e.g. [i32; N]. `{0:-1:-1 float}` then means one pointer at offset 0, if you dereference it there +//! will be only pointers, if you dereference these new pointers they will point to array of floats. +//!

17:15:53 -0400 Subject: [PATCH 068/118] Mark LazyCell::into_inner unstably const Other cell `into_inner` functions are const and there shouldn't be any problem here.

Emscripten is +a C/C++ toolchain designed to make it as easy as possible to port C/C++ code +written for Linux to run on the web or in other JavaScript runtimes such as Node. +It thus provides POSIX-compatible (musl) `libc` and `libstd` implementations and +many Linux APIs, access to the OpenGL and SDL APIs, and the ability to run arbitrary +JavaScript code, all based on web APIs using JS glue code. With the +`wasm32-unknown-emscripten` target, Rust code can interoperate with Emscripten's +ecosystem, C/C++ and JS code, and web APIs. + +One existing user of this target is the +[`pyodide` project](https://pyodide.org/) which provides a Python runtime in +WebAssembly using Emscripten and compiles Python extension modules written in Rust +to the `wasm32-unknown-emscripten` target. + +If you want to generate a standalone WebAssembly binary that does not require +access to the web APIs or the Rust standard library, the +[`wasm32-unknown-unknown`](./wasm32-unknown-unknown.md) target may be better +suited for you. However, [`wasm32-unknown-unknown`](./wasm32-unknown-unknown.md) +does not (easily) support interop with C/C++ code. Please refer to the +[wasm-bindgen](https://crates.io/crates/wasm-bindgen) crate in case you want to +interoperate with JavaScript with this target. + +Like Emscripten, the WASI targets [`wasm32-wasip1`](./wasm32-wasip1.md) and +[`wasm32-wasip2`](./wasm32-wasip2.md) also provide access to the host environment, +support interop with C/C++ (and other languages), and support most of the Rust +standard library. While the WASI targets are portable across different hosts +(web and non-web), WASI has no standard way of accessing web APIs, whereas +Emscripten has the ability to run arbitrary JS from WASM and access many web APIs. +If you are only targeting the web and need to access web APIs, the +`wasm32-unknown-emscripten` target may be preferable. + +## Target maintainers + +- Hood Chatham, https://github.com/hoodmane +- Juniper Tyree, https://github.com/juntyr + +## Requirements + +This target is cross-compiled. The Emscripten compiler toolchain `emcc` must be +installed to link WASM binaries for this target.

A minimal example configuration would be: + +```toml +[llvm] +targets = "WebAssembly" + +[build] +build-stage = 1 +target = ["wasm32-unknown-emscripten"] +``` + +## Building Rust programs + +Rust programs can be compiled by adding this target via rustup: + +```sh +$ rustup target add wasm32-unknown-emscripten +``` + +and then compiling with the target: + +```sh +$ rustc foo.rs --target wasm32-unknown-emscripten +$ file foo.wasm +``` + +## Cross-compilation + +This target can be cross-compiled from any host. + +## Emscripten ABI Compatibility + +The Emscripten compiler toolchain does not follow a semantic versioning scheme +that clearly indicates when breaking changes to the ABI can be made. Additionally, +Emscripten offers many different ABIs even for a single version of Emscripten +depending on the linker flags used, e.g. `-fexceptions` and `-sWASM_BIGINT`. If +the ABIs mismatch, your code may exhibit undefined behaviour. + +To ensure that the ABIs of your Rust code, of the Rust standard library, and of +other code compiled for Emscripten all match, you should rebuild the Rust standard +library with your local Emscripten version and settings using: + +```sh +cargo +nightly -Zbuild-std build +``` + +If you still want to use the pre-compiled `std` from rustup, you should ensure +that your local Emscripten matches the version used by Rust and be careful about +any `-C link-arg`s that you compiled your Rust code with. + +## Testing + +This target is not extensively tested in CI for the rust-lang/rust repository. It +can be tested locally, for example, with: + +```sh +./x.py test --target wasm32-unknown-emscripten --skip src/tools/linkchecker +``` + +To run these tests, both `emcc` and `node` need to be in your `$PATH`. You can +install `node`, for example, using `nvm` by following the instructions at +. + +If you need to test WebAssembly compatibility *in general*, it is recommended +to test the [`wasm32-wasip1`](./wasm32-wasip1.md) target instead. + +## Conditionally compiling code + +It's recommended to conditionally compile code for this target with: + +```text +#[cfg(target_os = "emscripten")] +``` + +It may sometimes be necessary to conditionally compile code for WASM targets +which do *not* use emscripten, which can be achieved with: + +```text +#[cfg(all(target_family = "wasm", not(target_os = "emscripten)))] +``` + +## Enabled WebAssembly features + +WebAssembly is an evolving standard which adds new features such as new +instructions over time.
