+
+ ### `simd-accel`
+
+-Enables SSE2 acceleration on x86 and x86_64 and NEON acceleration on Aarch64
+-and ARMv7. _Enabling this cargo feature is recommended when building for x86,
+-x86_64, ARMv7 or Aarch64._ The intention is for the functionality enabled by
+-this feature to become the normal on-by-default behavior once
+-[portable SIMD](https://github.com/rust-lang/rfcs/pull/2366) becames part of
+-stable Rust.
+-
+-Enabling this feature breaks the build unless the target is x86 with SSE2
+-(Rust's default 32-bit x86 target, `i686`, has SSE2, but Linux distros may
+-use an x86 target without SSE2, i.e. `i586` in `rustup` terms), ARMv7 or
+-thumbv7 with NEON (`-C target_feature=+neon`), x86_64 or Aarch64.
++Enables SIMD acceleration using the nightly-dependent `packed_simd` crate.
++
++This is an opt-in feature, because enabling this feature _opts out_ of Rust's
++guarantees of future compilers compiling old code (aka. "stability story").
++
++Currently, this has not been tested to be an improvement except for these
++targets:
++
++* x86_64
++* i686
++* aarch64
++* thumbv7neon
++
++If you use nightly Rust, you use targets whose first component is one of the
++above, and you are prepared _to have to revise your configuration when updating
++Rust_, you should enable this feature. Otherwise, please _do not_ enable this
++feature.
++
++_Note!_ If you are compiling for a target that does not have 128-bit SIMD
++enabled as part of the target definition and you are enabling 128-bit SIMD
++using `-C target_feature`, you need to enable the `core_arch` Cargo feature
++for `packed_simd` to compile a crates.io snapshot of `core_arch` instead of
++using the standard-library copy of `core::arch`, because the `core::arch`
++module of the pre-compiled standard library has been compiled with the
++assumption that the CPU doesn't have 128-bit SIMD. At present this applies
++mainly to 32-bit ARM targets whose first component does not include the
++substring `neon`.
++
++The encoding_rs side of things has not been properly set up for POWER,
++PowerPC, MIPS, etc., SIMD at this time, so even if you were to follow
++the advice from the previous paragraph, you probably shouldn't use
++the `simd-accel` option on the less mainstream architectures at this
++time.

++# Contributing to `packed_simd`
++
++Welcome! If you are reading this document, it means you are interested in contributing
++to the `packed_simd` crate.
++
++## Reporting issues
++
++All issues with this crate are tracked using GitHub's [Issue Tracker].
++
++You can use issues to bring bugs to the attention of the maintainers, to discuss
++certain problems encountered with the crate, or to request new features (although
++feature requests should be limited to things mentioned in the [RFC]).
++
++One thing to keep in mind is to always use the **latest** nightly toolchain when
++working on this crate. Due to the nature of this project, we use a lot of unstable
++features, meaning breakage happens often.
++
++[Issue Tracker]: https://github.com/rust-lang-nursery/packed_simd/issues
++[RFC]: https://github.com/rust-lang/rfcs/pull/2366
++
++### LLVM issues
++
++The Rust compiler relies on [LLVM](https://llvm.org/) for machine code generation,
++and quite a few LLVM bugs have been discovered during the development of this project.
++
++If you encounter issues with incorrect/suboptimal codegen, which you do not encounter
++when using the [SIMD vendor intrinsics](https://doc.rust-lang.org/nightly/std/arch/),
++it is likely the issue is with LLVM, or this crate's interaction with it.
++
++You should first open an issue **in this repo** to help us track the problem, and we
++will help determine what is the exact cause of the problem.
++If LLVM is indeed the cause, the issue will be reported upstream to the
++[LLVM bugtracker](https://bugs.llvm.org/).
++
++## Submitting Pull Requests
++
++New code is submitted to the crate using GitHub's [pull request] mechanism.
++You should first fork this repository, make your changes (preferrably in a new
++branch), then use GitHub's web UI to create a new PR.
++
++[pull request]: https://help.github.com/articles/about-pull-requests/
++
++### Examples
++
++The `examples` directory contains code showcasing SIMD code written with this crate,
++usually in comparison to scalar or ISPC code. If you have a project / idea which
++uses SIMD, we'd love to add it to the examples list.
++
++Every example should include a small `README`, describing the example code's purpose.
++If your example could potentially work as a benchmark, then add a `benchmark.sh`
++script to allow running the example benchmark code in CI. See an existing example's
++[`benchmark.sh`](examples/aobench/benchmark.sh) for a sample.
++
++Don't forget to update the crate's top-level `README` with a link to your example.
++
++### Perf guide
++
++The objective of the [performance guide][perf-guide] is to be a comprehensive
++resource detailing the process of optimizing Rust code with SIMD support.
++
++If you believe a certain section could be reworded, or if you have any tips & tricks
++related to SIMD which you'd like to share, please open a PR.
++
++[mdBook] is used to manage the formatting of the guide as a book.

++# Bounds checking
++
++Reading and writing packed vectors to/from slices is checked by default.
++Independently of the configuration options used, the safe functions:
++
++* `Simd<[T; N]>::from_slice_aligned(& s[..])`
++* `Simd<[T; N]>::write_to_slice_aligned(&mut s[..])`
++
++always check that:
++
++* the slice is big enough to hold the vector
++* the slice is suitably aligned to perform an aligned load/store for a `Simd<[T;
++ N]>` (this alignment is often much larger than that of `T`).
++
++There are `_unaligned` versions that use unaligned load and stores, as well as
++`unsafe` `_unchecked` that do not perform any checks iff `debug-assertions =
++false` / `debug = false`. That is, the `_unchecked` methods do still assert size
++and alignment in debug builds and could also do so in release builds depending
++on the configuration options.
++
++These assertions do often significantly impact performance and you should be
++aware of them.

++# Performance profiling on Linux
++
++## Using `perf`
++
++[perf](https://perf.wiki.kernel.org/) is the most powerful performance profiler
++for Linux, featuring support for various hardware Performance Monitoring Units,
++as well as integration with the kernel's performance events framework.
++
++We will only look at how can the `perf` command can be used to profile SIMD code.
++Full system profiling is outside of the scope of this book.
++
++### Recording
++
++The first step is to record a program's execution during an average workload.
++It helps if you can isolate the parts of your program which have performance
++issues, and set up a benchmark which can be easily (re)run.
++
++Build the benchmark binary in release mode, after having enabled debug info:
++
++```sh
++$ cargo build --release
++Finished release [optimized + debuginfo] target(s) in 0.02s
++```
++
++Then use the `perf record` subcommand:
++
++```sh
++$ perf record --call-graph=dwarf ./target/release/my-program
++[ perf record: Woken up 10 times to write data ]
++[ perf record: Captured and wrote 2,356 MB perf.data (292 samples) ]
++```
++
++Instead of using `--call-graph=dwarf`, which can become pretty slow, you can use
++`--call-graph=lbr` if you have a processor with support for Last Branch Record
++(i.e. Intel Haswell and newer).
++
++`perf` will, by default, record the count of CPU cycles it takes to execute
++various parts of your program. You can use the `-e` command line option
++to enable other performance events, such as `cache-misses`. Use `perf list`
++to get a list of all hardware counters supported by your CPU.
++
++### Viewing the report
++
++The next step is getting a bird's eye view of the program's execution.
++`perf` provides a `ncurses`-based interface which will get you started.
++
++Use `perf report` to open a visualization of your program's performance:
++
++```sh
++perf report --hierarchy -M intel
++```
++
++`--hierarchy` will display a tree-like structure of where your program spent
++most of its time. `-M intel` enables disassembly output with Intel syntax, which
++is subjectively more readable than the default AT&T syntax.
++
++Here is the output from profiling the `nbody` benchmark:
++
++```
++- 100,00% nbody
++ - 94,18% nbody
++ + 93,48% [.] nbody_lib::simd::advance
++ + 0,70% [.] nbody_lib::run
++ + 5,06% libc-2.28.so
++```
++
++If you move with the arrow keys to any node in the tree, you can the press `a`
++to have `perf` _annotate_ that node. This means it will:
++
++- disassemble the function
++
++- associate every instruction with the percentage of time which was spent executing it
++
++- interleaves the disassembly with the source code,
++ assuming it found the debug symbols
++ (you can use `s` to toggle this behaviour)
++
++`perf` will, by default, open the instruction which it identified as being the
++hottest spot in the function:
++
++```
++0,76 │ movapd xmm2,xmm0
++0,38 │ movhlps xmm2,xmm0
++ │ addpd xmm2,xmm0
++ │ unpcklpd xmm1,xmm2
++12,50 │ sqrtpd xmm0,xmm1
++1,52 │ mulpd xmm0,xmm1
++```
++
++In this case, `sqrtpd` will be highlighted in red, since that's the instruction
++which the CPU spends most of its time executing.
++
++## Using Valgrind
++
++Valgrind is a set of tools which initially helped C/C++ programmers find unsafe
++memory accesses in their code. Nowadays the project also has
++
++- a heap profiler called `massif`
++
++- a cache utilization profiler called `cachegrind`
++
++- a call-graph performance profiler called `callgrind`
++
++<!--
++TODO: explain valgrind's dynamic binary translation, warn about massive
++slowdown, talk about `kcachegrind` for a GUI

++# Machine code analysis tools
++
++## The microarchitecture of modern CPUs
++
++While you might have heard of Instruction Set Architectures, such as `x86` or
++`arm` or `mips`, the term _microarchitecture_ (also written here as _µ-arch_),
++refers to the internal details of an actual family of CPUs, such as Intel's
++_Haswell_ or AMD's _Jaguar_.
++
++Replacing scalar code with SIMD code will improve performance on all CPUs
++supporting the required vector extensions.
++However, due to microarchitectural differences, the actual speed-up at
++runtime might vary.
++
++**Example**: a simple example arises when optimizing for AMD K8 CPUs.
++The assembly generated for an empty function should look like this:
++
++```asm
++nop
++ret
++```
++
++The `nop` is used to align the `ret` instruction for better performance.
++However, the compiler will actually generated the following code:
++
++```asm
++repz ret
++```
++
++The `repz` instruction will repeat the following instruction until a certain
++condition. Of course, in this situation, the function will simply immediately
++return, and the `ret` instruction is still aligned.
++However, AMD K8's branch predictor performs better with the latter code.
++
++For those looking to absolutely maximize performance for a certain target µ-arch,
++you will have to read some CPU manuals, or ask the compiler to do it for you
++with `-C target-cpu`.
++
++### Summary of CPU internals
++
++Modern processors are able to execute instructions out-of-order for better performance,
++by utilizing tricks such as [branch prediction], [instruction pipelining],
++or [superscalar execution].
++
++[branch prediction]: https://en.wikipedia.org/wiki/Branch_predictor
++[instruction pipelining]: https://en.wikipedia.org/wiki/Instruction_pipelining
++[superscalar execution]: https://en.wikipedia.org/wiki/Superscalar_processor
++
++SIMD instructions are also subject to these optimizations, meaning it can get pretty
++difficult to determine where the slowdown happens.
++For example, if the profiler reports a store operation is slow, one of two things
++could be happening:
++
++- the store is limited by the CPU's memory bandwidth, which is actually an ideal

++
++- memory bandwidth is nowhere near its peak, but the value to be stored is at the

++Certain tools have knowledge of internal CPU microarchitecture, i.e. they know

++
++- what [µ-ops] are generated for a set of instructions

++# Performance profiling
++
++While the rest of the book provides practical advice on how to improve the performance
++of SIMD code, this chapter is dedicated to [**performance profiling**][profiling].
++Profiling consists of recording a program's execution in order to identify program
++hotspots.
++
++**Important**: most profilers require debug information in order to accurately
++link the program hotspots back to the corresponding source code lines. Rust will
++disable debug info generation by default for optimized builds, but you can change
++that [in your `Cargo.toml`][cargo-ref].

++# Enabling target features
++
++Not all processors of a certain architecture will have SIMD processing units,
++and using a SIMD instruction which is not supported will trigger undefined behavior.
++
++To allow building safe, portable programs, the Rust compiler will **not**, by default,
++generate any sort of vector instructions, unless it can statically determine
++they are supported. For example, on AMD64, SSE2 support is architecturally guaranteed.
++The `x86_64-apple-darwin` target enables up to SSSE3. The get a defintive list of
++which features are enabled by default on various platforms, refer to the target
++specifications [in the compiler's source code][targets].

++# Target features in practice
++
++Using `RUSTFLAGS` will allow the crate being compiled, as well as all its
++transitive dependencies to use certain target features.
++
++A tehnique used to avoid undefined behavior at runtime is to compile and
++ship multiple binaries, each compiled with a certain set of features.
++This might not be feasible in some cases, and can quickly get out of hand
++as more and more vector extensions are added to an architecture.
++
++Rust can be more flexible: you can build a single binary/library which automatically
++picks the best supported vector instructions depending on the host machine.
++The trick consists of monomorphizing parts of the code during building, and then
++using run-time feature detection to select the right code path when running.
++
++<!-- TODO
++Explain how to create efficient functions that dispatch to different
++implementations at run-time without issues (e.g. using `#[inline(always)]` for
++the impls, wrapping in `#[target_feature]`, and the wrapping those in a function
++that does run-time feature detection).
++-->
++
++**NOTE** (x86 specific): because the AVX (256-bit) registers extend the existing
++SSE (128-bit) registers, mixing SSE and AVX instructions in a program can cause
++performance issues.
++
++The solution is to compile all code, even the code written with 128-bit vectors,
++with the AVX target feature enabled. This will cause the compiler to prefix the
++generated instructions with the [VEX] prefix.

++# Using RUSTFLAGS
++
++One of the easiest ways to benefit from SIMD is to allow the compiler
++to generate code using certain vector instruction extensions.
++
++The environment variable `RUSTFLAGS` can be used to pass options for code
++generation to the Rust compiler. These flags will affect **all** compiled crates.
++
++There are two flags which can be used to enable specific vector extensions:
++
++## target-feature
++
++- Syntax: `-C target-feature=<features>`
++
++- Provides the compiler with a comma-separated set of instruction extensions
++ to enable.
++
++ **Example**: Use `-C target-features=+sse3,+avx` to enable generating instructions
++ for [Streaming SIMD Extensions 3](https://en.wikipedia.org/wiki/SSE3) and
++ [Advanced Vector Extensions](https://en.wikipedia.org/wiki/Advanced_Vector_Extensions).
++
++- To list target triples for all targets supported by Rust, use:
++
++ ```sh
++ rustc --print target-list
++ ```
++
++- To list all support target features for a certain target triple, use:
++
++ ```sh
++ rustc --target=${TRIPLE} --print target-features
++ ```
++
++- Note that all CPU features are independent, and will have to be enabled individually.
++
++ **Example**: Setting `-C target-features=+avx2` will _not_ enable `fma`, even though
++ all CPUs which support AVX2 also support FMA. To enable both, one has to use
++ `-C target-features=+avx2,+fma`
++
++- Some features also depend on other features, which need to be enabled for the
++ target instructions to be generated.
++
++ **Example**: Unless `v7` is specified as the target CPU (see below), to enable
++ NEON on ARM it is necessary to use `-C target-feature=+v7,+neon`.
++
++## target-cpu
++
++- Syntax: `-C target-cpu=<cpu>`
++
++- Sets the identifier of a CPU family / model for which to build and optimize the code.
++
++ **Example**: `RUSTFLAGS='-C target-cpu=cortex-a75'`
++
++- To list all supported target CPUs for a certain target triple, use:
++
++ ```sh
++ rustc --target=${TRIPLE} --print target-cpus
++ ```
++
++ **Example**:
++
++ ```sh
++ rustc --target=i686-pc-windows-msvc --print target-cpus
++ ```
++
++- The compiler will translate this into a list of target features. Therefore,
++ individual feature checks (`#[cfg(target_feature = "...")]`) will still
++ work properly.
++
++- It will cause the code generator to optimize the generated code for that
++ specific CPU model.
++
++- Using `native` as the CPU model will cause Rust to generate and optimize code
++ for the CPU running the compiler. It is useful when building programs which you
++ plan to only use locally. This should never be used when the generated programs
++ are meant to be run on other computers, such as when packaging for distribution
++ or cross-compiling.

++# Vertical and horizontal operations
++
++In SIMD terminology, each vector has a certain "width" (number of lanes).
++A vector processor is able to perform two kinds of operations on a vector:
++
++- Vertical operations:
++ operate on two vectors of the same width, result has same width
++
++**Example**: vertical addition of two `f32x4` vectors
++
++ %0 == | 2 | -3.5 | 0 | 7 |
++ + + + +
++ %1 == | 4 | 1.5 | -1 | 0 |
++ = = = =
++ %0 + %1 == | 6 | -2 | -1 | 7 |
++
++- Horizontal operations:
++ reduce the elements of two vectors in some way,
++ the result's elements combine information from the two original ones
++
++**Example**: horizontal addition of two `u64x2` vectors
++
++ %0 == | 1 | 3 |
++ └─+───┘
++ └───────┐
++ │
++ %1 == | 4 | -1 | │
++ └─+──┘ │
++ └───┐ │
++ │ │
++ ┌─────│───┘
++ ▼ ▼
++ %0 + %1 == | 4 | 3 |
++
++## Performance consideration of horizontal operations
++
++The result of vertical operations, like vector negation: `-a`, for a given lane,
++does not depend on the result of the operation for the other lanes. The result
++of horizontal operations, like the vector `sum` reduction: `a.sum()`, depends on
++the value of all vector lanes.
++
++In virtually all architectures vertical operations are fast, while horizontal
++operations are, by comparison, very slow.
++
++Consider the following two functions for computing the sum of all `f32` values
++in a slice:
++
++```rust
++fn fast_sum(x: &[f32]) -> f32 {
++ assert!(x.len() % 4 == 0);
++ let mut sum = f32x4::splat(0.); // [0., 0., 0., 0.]
++ for i in (0..x.len()).step_by(4) {
++ sum += f32x4::from_slice_unaligned(&x[i..]);
++ }
++ sum.sum()
++}
++
++fn slow_sum(x: &[f32]) -> f32 {
++ assert!(x.len() % 4 == 0);
++ let mut sum: f32 = 0.;
++ for i in (0..x.len()).step_by(4) {
++ sum += f32x4::from_slice_unaligned(&x[i..]).sum();
++ }
++ sum
++}
++```
++
++The inner loop over the slice is where the bulk of the work actually happens.
++There, the `fast_sum` function perform vertical operations into a vector, doing
++a single horizontal reduction at the end, while the `slow_sum` function performs
++horizontal vector operations inside of the loop.
++
++On all widely-used architectures, `fast_sum` is a large constant factor faster
++than `slow_sum`. You can run the [slice_sum]() example and see for yourself. On
++the particular machine tested there the algorithm using the horizontal vector
++addition is 2.7x slower than the one using vertical vector operations!

++## Implementation of [Rust RFC #2366: `std::simd`][rfc2366]
++
++[![Travis-CI Status]][travis] [![Appveyor Status]][appveyor] [![Latest Version]][crates.io] [![docs]][master_docs]
++
++> This aims to be a 100% conforming implementation of Rust RFC 2366 for stabilization.
++
++**WARNING**: this crate only supports the most recent nightly Rust toolchain.
++
++## Documentation

++* [API docs (`master` branch)][master_docs]
++* [Performance guide][perf_guide]
++* [API docs (`docs.rs`)][docs.rs]: **CURRENTLY DOWN** due to
++ https://github.com/rust-lang-nursery/packed_simd/issues/110
++* [RFC2366 `std::simd`][rfc2366]: - contains motivation, design rationale,
++ discussion, etc.
++
++## Examples
++
++Most of the examples come with both a scalar and a vectorized implementation.
++
++* [`aobench`](https://github.com/rust-lang-nursery/packed_simd/tree/master/examples/aobench)
++* [`fannkuch_redux`](https://github.com/rust-lang-nursery/packed_simd/tree/master/examples/fannkuch_redux)

++* [`options_pricing`](https://github.com/rust-lang-nursery/packed_simd/tree/master/examples/options_pricing)
++* [`spectral_norm`](https://github.com/rust-lang-nursery/packed_simd/tree/master/examples/spectral_norm)
++* [`triangle transform`](https://github.com/rust-lang-nursery/packed_simd/tree/master/examples/triangle_xform)
++* [`stencil`](https://github.com/rust-lang-nursery/packed_simd/tree/master/examples/stencil)
++* [`vector dot product`](https://github.com/rust-lang-nursery/packed_simd/tree/master/examples/dot_product)
++
++## Cargo features
++
++* `into_bits` (default: disabled): enables `FromBits`/`IntoBits` trait
++ implementations for the vector types. These allow reinterpreting the bits of a
++ vector type as those of another vector type safely by just using the
++ `.into_bits()` method.
++
++* `core_arch` (default: disabled): enable this feature to recompile `core::arch`
++ for the target-features enabled. `packed_simd` includes optimizations for some
++ target feature combinations that are enabled by this feature. Note, however,
++ that this is an unstable dependency, that rustc might break at any time.
++
++* `sleef-sys` (default: disabled - `x86_64` only): internally uses the [SLEEF]
++ short-vector math library when profitable via the [`sleef-sys`][sleef_sys]
++ crate. [SLEEF] is licensed under the [Boost Software License
++ v1.0][boost_license], an extremely permissive license, and can be statically
++ linked without issues.
++
++## Performance
++
++The following [ISPC] examples are also part of `packed_simd`'s
++[`examples/`](https://github.com/rust-lang-nursery/packed_simd/tree/master/examples/)
++directory, where `packed_simd`+[`rayon`][rayon] are used to emulate [ISPC]'s
++Single-Program-Multiple-Data (SPMD) programming model. The performance results
++on different hardware is shown in the `readme.md` of each example. The following
++table summarizes the performance ranges, where `+` means speed-up and `-`
++slowdown:
++
++* `aobench`: `[-1.02x, +1.53x]`,
++* `stencil`: `[+1.06x, +1.72x]`,
++* `mandelbrot`: `[-1.74x, +1.2x]`,
++* `options_pricing`:
++ * `black_scholes`: `+1.0x`
++ * `binomial_put`: `+1.4x`
++
++ While SPMD is not the intended use case for `packed_simd`, it is possible to
++ combine the library with [`rayon`][rayon] to poorly emulate [ISPC]'s SPMD programming
++ model in Rust. Writing performant code is not as straightforward as with
++ [ISPC], but with some care (e.g. see the [Performance Guide][perf_guide]) one
++ can easily match and often out-perform [ISPC]'s "default performance".
++
++## Platform support

++library compiles without issues for a given target, while `run` shows whether
++the full testsuite passes on the target.

++//! Implements portable vector shuffles with immediate indices.
++
++// FIXME: comprehensive tests
++// https://github.com/rust-lang-nursery/packed_simd/issues/20
++
++/// Shuffles vector elements.
++///
++/// This macro returns a new vector that contains a shuffle of the elements in
++/// one (`shuffle!(vec, [indices...])`) or two (`shuffle!(vec0, vec1,
++/// [indices...])`) input vectors.
++///
++/// The type of `vec0` and `vec1` must be equal, and the element type of the
++/// resulting vector is the element type of the input vector.
++///
++/// The number of `indices` must be a power-of-two in range `[0, 64)`, since
++/// currently, the largest vector supported by the library has 64 lanes. The
++/// length of the resulting vector equals the number of indices provided.
++///
++/// The indices must be in range `[0, M * N)` where `M` is the number of input
++/// vectors (`1` or `2`) and `N` is the number of lanes of the input vectors.
++/// The indices `i` in range `[0, N)` refer to the `i`-th element of `vec0`,
++/// while the indices in range `[N, 2*N)` refer to the `i - N`-th element of
++/// `vec1`.
++///
++/// # Examples
++///
++/// Shuffling elements of two vectors:
++///
++/// ```
++/// # #[macro_use]
++/// # extern crate packed_simd;
++/// # use packed_simd::*;
++/// # fn main() {
++/// // Shuffle allows reordering the elements:
++/// let x = i32x4::new(1, 2, 3, 4);
++/// let y = i32x4::new(5, 6, 7, 8);
++/// let r = shuffle!(x, y, [4, 0, 5, 1]);
++/// assert_eq!(r, i32x4::new(5, 1, 6, 2));
++///
++/// // The resulting vector can als be smaller than the input:
++/// let r = shuffle!(x, y, [1, 6]);
++/// assert_eq!(r, i32x2::new(2, 7));
++///
++/// // Or larger:
++/// let r = shuffle!(x, y, [1, 3, 4, 2, 1, 7, 2, 2]);
++/// assert_eq!(r, i32x8::new(2, 4, 5, 3, 2, 8, 3, 3));
++/// // At most 2 * the number of lanes in the input vector.
++/// # }
++/// ```
++///
++/// Shuffling elements of one vector:
++///
++/// ```
++/// # #[macro_use]
++/// # extern crate packed_simd;
++/// # use packed_simd::*;
++/// # fn main() {
++/// // Shuffle allows reordering the elements of a vector:
++/// let x = i32x4::new(1, 2, 3, 4);

++//! # Portable packed SIMD vectors
++//!
++//! This crate is proposed for stabilization as `std::packed_simd` in [RFC2366:
++//! `std::simd`](https://github.com/rust-lang/rfcs/pull/2366) .
++//!
++//! The examples available in the
++//! [`examples/`](https://github.com/rust-lang-nursery/packed_simd/tree/master/examples)
++//! sub-directory of the crate showcase how to use the library in practice.
++//!
++//! ## Table of contents
++//!
++//! - [Introduction](#introduction)
++//! - [Vector types](#vector-types)
++//! - [Conditional operations](#conditional-operations)
++//! - [Conversions](#conversions)
++//! - [Performance
++//! guide](https://rust-lang-nursery.github.io/packed_simd/perf-guide/)
++//!
++//! ## Introduction
++//!
++//! This crate exports [`Simd<[T; N]>`][`Simd`]: a packed vector of `N`
++//! elements of type `T` as well as many type aliases for this type: for
++//! example, [`f32x4`], which is just an alias for `Simd<[f32; 4]>`.
++//!
++//! The operations on packed vectors are, by default, "vertical", that is, they
++//! are applied to each vector lane in isolation of the others:
++//!
++//! ```
++//! # use packed_simd::*;
++//! let a = i32x4::new(1, 2, 3, 4);
++//! let b = i32x4::new(5, 6, 7, 8);
++//! assert_eq!(a + b, i32x4::new(6, 8, 10, 12));
++//! ```
++//!
++//! Many "horizontal" operations are also provided:
++//!
++//! ```
++//! # use packed_simd::*;
++//! # let a = i32x4::new(1, 2, 3, 4);
++//! assert_eq!(a.wrapping_sum(), 10);
++//! ```
++//!
++//! In virtually all architectures vertical operations are fast, while
++//! horizontal operations are, by comparison, much slower. That is, the
++//! most portably-efficient way of performing a reduction over a slice
++//! is to collect the results into a vector using vertical operations,
++//! and performing a single horizontal operation at the end:
++//!
++//! ```
++//! # use packed_simd::*;
++//! fn reduce(x: &[i32]) -> i32 {
++//! assert!(x.len() % 4 == 0);
++//! let mut sum = i32x4::splat(0); // [0, 0, 0, 0]
++//! for i in (0..x.len()).step_by(4) {
++//! sum += i32x4::from_slice_unaligned(&x[i..]);
++//! }
++//! sum.wrapping_sum()
++//! }
++//!
++//! let x = [0, 1, 2, 3, 4, 5, 6, 7];
++//! assert_eq!(reduce(&x), 28);
++//! ```
++//!
++//! ## Vector types
++//!
++//! The vector type aliases are named according to the following scheme:
++//!
++//! > `{element_type}x{number_of_lanes} == Simd<[element_type;
++//! number_of_lanes]>`
++//!
++//! where the following element types are supported:
++//!
++//! * `i{element_width}`: signed integer
++//! * `u{element_width}`: unsigned integer
++//! * `f{element_width}`: float
++//! * `m{element_width}`: mask (see below)
++//! * `*{const,mut} T`: `const` and `mut` pointers
++//!
++//! ## Basic operations
++//!
++//! ```
++//! # use packed_simd::*;
++//! // Sets all elements to `0`:
++//! let a = i32x4::splat(0);
++//!
++//! // Reads a vector from a slice:
++//! let mut arr = [0, 0, 0, 1, 2, 3, 4, 5];
++//! let b = i32x4::from_slice_unaligned(&arr);
++//!
++//! // Reads the 4-th element of a vector:
++//! assert_eq!(b.extract(3), 1);
++//!
++//! // Returns a new vector where the 4-th element is replaced with `1`:
++//! let a = a.replace(3, 1);
++//! assert_eq!(a, b);
++//!
++//! // Writes a vector to a slice:
++//! let a = a.replace(2, 1);
++//! a.write_to_slice_unaligned(&mut arr[4..]);
++//! assert_eq!(arr, [0, 0, 0, 1, 0, 0, 1, 1]);
++//! ```
++//!
++//! ## Conditional operations
++//!
++//! One often needs to perform an operation on some lanes of the vector. Vector
++//! masks, like `m32x4`, allow selecting on which vector lanes an operation is
++//! to be performed:
++//!
++//! ```
++//! # use packed_simd::*;
++//! let a = i32x4::new(1, 1, 2, 2);
++//!
++//! // Add `1` to the first two lanes of the vector.
++//! let m = m16x4::new(true, true, false, false);
++//! let a = m.select(a + 1, a);
++//! assert_eq!(a, i32x4::splat(2));
++//! ```
++//!
++//! The elements of a vector mask are either `true` or `false`. Here `true`
++//! means that a lane is "selected", while `false` means that a lane is not
++//! selected.
++//!
++//! All vector masks implement a `mask.select(a: T, b: T) -> T` method that
++//! works on all vectors that have the same number of lanes as the mask. The
++//! resulting vector contains the elements of `a` for those lanes for which the
++//! mask is `true`, and the elements of `b` otherwise.
++//!
++//! The example constructs a mask with the first two lanes set to `true` and
++//! the last two lanes set to `false`. This selects the first two lanes of `a +
++//! 1` and the last two lanes of `a`, producing a vector where the first two
++//! lanes have been incremented by `1`.
++//!
++//! > note: mask `select` can be used on vector types that have the same number
++//! > of lanes as the mask. The example shows this by using [`m16x4`] instead
++//! > of [`m32x4`]. It is _typically_ more performant to use a mask element
++//! > width equal to the element width of the vectors being operated upon.
++//! > This is, however, not true for 512-bit wide vectors when targetting
++//! > AVX-512, where the most efficient masks use only 1-bit per element.
++//!
++//! All vertical comparison operations returns masks:
++//!
++//! ```
++//! # use packed_simd::*;
++//! let a = i32x4::new(1, 1, 3, 3);
++//! let b = i32x4::new(2, 2, 0, 0);
++//!
++//! // ge: >= (Greater Eequal; see also lt, le, gt, eq, ne).
++//! let m = a.ge(i32x4::splat(2));
++//!
++//! if m.any() {
++//! // all / any / none allow coherent control flow
++//! let d = m.select(a, b);
++//! assert_eq!(d, i32x4::new(2, 2, 3, 3));
++//! }
++//! ```
++//!
++//! ## Conversions
++//!
++//! * **lossless widening conversions**: [`From`]/[`Into`] are implemented for
++//! vectors with the same number of lanes when the conversion is value
++//! preserving (same as in `std`).
++//!
++//! * **safe bitwise conversions**: The cargo feature `into_bits` provides the
++//! `IntoBits/FromBits` traits (`x.into_bits()`). These perform safe bitwise
++//! `transmute`s when all bit patterns of the source type are valid bit
++//! patterns of the target type and are also implemented for the
++//! architecture-specific vector types of `std::arch`. For example, `let x:
++//! u8x8 = m8x8::splat(true).into_bits();` is provided because all `m8x8` bit
++//! patterns are valid `u8x8` bit patterns. However, the opposite is not
++//! true, not all `u8x8` bit patterns are valid `m8x8` bit-patterns, so this
++//! operation cannot be peformed safely using `x.into_bits()`; one needs to
++//! use `unsafe { crate::mem::transmute(x) }` for that, making sure that the
++//! value in the `u8x8` is a valid bit-pattern of `m8x8`.
++//!
++//! * **numeric casts** (`as`): are peformed using [`FromCast`]/[`Cast`]
++//! (`x.cast()`), just like `as`:
++//!
++//! * casting integer vectors whose lane types have the same size (e.g.
++//! `i32xN` -> `u32xN`) is a **no-op**,
++//!
++//! * casting from a larger integer to a smaller integer (e.g. `u32xN` ->
++//! `u8xN`) will **truncate**,
++//!
++//! * casting from a smaller integer to a larger integer (e.g. `u8xN` ->
++//! `u32xN`) will:
++//! * **zero-extend** if the source is unsigned, or
++//! * **sign-extend** if the source is signed,
++//!
++//! * casting from a float to an integer will **round the float towards
++//! zero**,
++//!
++//! * casting from an integer to float will produce the floating point
++//! representation of the integer, **rounding to nearest, ties to even**,
++//!
++//! * casting from an `f32` to an `f64` is perfect and lossless,
++//!
++//! * casting from an `f64` to an `f32` **rounds to nearest, ties to even**.
++//!
++//! Numeric casts are not very "precise": sometimes lossy, sometimes value
++//! preserving, etc.

+-`simd` offers a basic interface to the SIMD functionality of CPUs. (Note: This crate fails to build unless the target is aarch64, x86_64, i686 (i.e. SSE2 enabled; not i586) or an ARMv7 target (thumb or not) with NEON enabled.)
+-
+-This crate is expected to become _obsolete_ once the implementation of [RFC 2366](https://github.com/rust-lang/rfcs/pull/2366) lands in the standard library.

-Bug 1463035 - Remove MOZ_SIGNAL_TRAMPOLINE. r=jchen

-For some reason, GNU as is not happy with the assembly generated after
-bug 1238661 anymore on Debian armel.
-
-OTOH, as mentioned in bug 1238661 comment 4, we actually don't need this
-workaround anymore, so let's just kill it.
