-+# any_all_workaround
-+
-+This is a workaround for bad codegen ([Rust
bug](https://github.com/rust-lang/portable-simd/issues/146), [LLVM
bug](https://github.com/llvm/llvm-project/issues/50466)) for the `any()` and
`all()` reductions for NEON-backed SIMD vectors on 32-bit ARM. On other
platforms these delegate to `any()` and `all()` in `core::simd`.
-+
-+The plan is to abandon this crate once the LLVM bug is fixed or
`core::simd` works around the LLVM bug.
-+
-+The code is forked from the [`packed_simd`
crate](https://raw.githubusercontent.com/hsivonen/packed_simd/d938e39bee9bc5c222f5f2f2a0df9e53b5ce36ae/src/codegen/reductions/mask/arm.rs).
-+
-+This crate requires Nightly Rust as it depends on the `portable_simd`
feature.
-+
-+# License
-+
-+`MIT OR Apache-2.0`, since that's how `packed_simd` is licensed. (The ARM
intrinsics Rust version workaround is from qcms, see LICENSE-MIT-QCMS.)

-
- ### `simd-accel`
-
--Enables SIMD acceleration using the nightly-dependent `packed_simd` crate.
-+Enables SIMD acceleration using the nightly-dependent `portable_simd`
standard
-+library feature.
-
- 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:
-+targets and enabling the `simd-accel` feature is expected to break the build
-+on other 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.

- ## Release Notes
-
-+### 0.8.34
-+
-+* Use the `portable_simd` nightly feature of the standard library instead
of the `packed_simd` crate. Only affects the `simd-accel` optional nightly
feature.
-+* Internal documentation improvements and minor code improvements around
`unsafe`.
-+* Added `rust-version` to `Cargo.toml`.
-+
- ### 0.8.33
-
- * Use `packed_simd` instead of `packed_simd_2` again now that updates are
back under the `packed_simd` name. Only affects the `simd-accel` optional
nightly feature.

--
--## Implementation of [Rust RFC #2366: `std::simd`][rfc2366]
--
--[![Latest Version]][crates.io] [![docs]][master_docs]
--
--**WARNING**: this crate only supports the most recent nightly Rust toolchain
--and will be superseded by
[`#![feature(portable_simd)]`](https://github.com/rust-lang/portable-simd).
--
--## Documentation
--
--* [API docs (`master` branch)][master_docs]
--* [Performance guide][perf_guide]
--* [API docs (`docs.rs`)][docs.rs]
--* [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.
--
--## 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 test suite passes for a given target.
--
--| **Linux** | **build** | **run** |

--## Machine code verification
--
--The
--[`verify/`](https://github.com/rust-lang-nursery/packed_simd/tree/master/verify)
--crate tests disassembles the portable packed vector APIs at run-time and
--compares the generated machine code against the desired one to make sure
that
--this crate remains efficient.

--# 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.

--
--### 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 (preferably 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;

--
--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.

--# 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-feature=+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=${TRIPLE} --print target-features
-- ```
--
--- Note that all CPU features are independent, and will have to be enabled
individually.
--
-- **Example**: Setting `-C target-feature=+avx2` will _not_ enable `fma`,
even though
-- all CPUs which support AVX2 also support FMA. To enable both, one has to
use
-- `-C target-feature=+avx2,+fma`
--
--- Some features also depend on other features, which need to be enabled for
the
-- target instructions to be generated.
--
-- **Example**: Unless `v7` is specified as the target CPU (see below), to
enable
-- NEON on ARM it is necessary to use `-C target-feature=+v7,+neon`.
--
--## target-cpu
--
--- Syntax: `-C target-cpu=<cpu>`
--
--- Sets the identifier of a CPU family / model for which to build and
optimize the code.
--
-- **Example**: `RUSTFLAGS='-C target-cpu=cortex-a75'`
--
--- To list all supported target CPUs for a certain target triple, use:
--
-- ```sh
-- rustc --target=${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!

--//! 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:
--///
--/// ```
--/// # 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:
--///
--/// ```
--/// # use packed_simd::*;
--/// # fn main() {
--/// // Shuffle allows reordering the elements of a vector:
--/// let x = i32x4::new(1, 2, 3, 4);
--/// let r = shuffle!(x, [2, 1, 3, 0]);

--//! # Portable packed SIMD vectors
--//!
--//! This crate is proposed for stabilization as `std::packed_simd` in

--//! `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

--//! - [Hardware Features](#hardware-features)
--//! - [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_eq!(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 targeting
--//! > 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 performed 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 performed 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.
--//!
--//! ## Hardware Features
--//!
--//! This crate can use different hardware features based on your configured
--//! `RUSTFLAGS`. For example, with no configured `RUSTFLAGS`, `u64x8` on
--//! x86_64 will use SSE2 operations like `PCMPEQD`. If you configure
--//! `RUSTFLAGS='-C target-feature=+avx2,+avx'` on supported x86_64 hardware
--//! the same `u64x8` may use wider AVX2 operations like `VPCMPEQQ`. It is
--//! important for performance and for hardware support requirements that
--//! you choose an appropriate set of `target-feature` and `target-cpu`
--//! options during builds. For more information, see the [Performance
--//! guide](https://rust-lang-nursery.github.io/packed_simd/perf-guide/)

-Bug 1889045 - Update sandbox policies for `epoll_pwait2`. r=gcp
-
-Note that this can't easily be unit-tested, because the tests can't
-distinguish between the real `ENOSYS` from lack of kernel support and
-the fake `ENOSYS` from the sandbox.
