@@ -126,17 +126,39 @@ There are currently these optional cargo features:
### `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

+# 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

+
+## 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
+ scenario, all things considered;
+
+- memory bandwidth is nowhere near its peak, but the value to be stored is at the
+ end of a long chain of operations, and this store is where the profiler
+ encountered the pipeline stall;
+
+Since most profilers are simple tools which don't understand the subtleties of
+instruction scheduling, you
+
+## Analyzing the machine code
+
+Certain tools have knowledge of internal CPU microarchitecture, i.e. they know
+
+- how many physical [register files] a CPU actually has
+
+- what is the latency / throughtput of an instruction
+
+- what [µ-ops] are generated for a set of instructions
+
+and many other architectural details.
+
+[register files]: https://en.wikipedia.org/wiki/Register_file
+[µ-ops]: https://en.wikipedia.org/wiki/Micro-operation
+
+These tools are therefore able to provide accurate information as to why some
+instructions are inefficient, and where the bottleneck is.
+
+The disadvantage is that the output of these tools requires advanced knowledge
+of the target architecture to understand, i.e. they **cannot** point out what
+the cause of the issue is explicitly.
+
+## Intel's Architecture Code Analyzer (IACA)
+
+[IACA] is a free tool offered by Intel for analyzing the performance of various
+computational kernels.
+
+Being a proprietary, closed source tool, it _only_ supports Intel's µ-arches.

+# 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)
+* [`matrix inverse`](https://github.com/rust-lang-nursery/packed_simd/tree/master/examples/matrix_inverse)
+* [`mandelbrot`](https://github.com/rust-lang-nursery/packed_simd/tree/master/examples/mandelbrot)
+* [`n-body`](https://github.com/rust-lang-nursery/packed_simd/tree/master/examples/nbody)
+* [`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

+The following table describes the supported platforms: `build` shows whether the
+library compiles without issues for a given target, while `run` shows whether
+the full testsuite passes on the target.

+
+// FIXME: comprehensive tests

+
+/// 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 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:

+/// // At most 2 * the number of lanes in the input vector.

+//! # 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.
