+# 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.)

## Optional features
There are currently these optional cargo features:
### `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.

### `serde`
Enables support for serializing and deserializing `&'static Encoding`-typed

## 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.
### 0.8.32
* Removed `build.rs`. (This removal should resolve false positives reported by some antivirus products. This may break some build configurations that have opted out of Rust's guarantees against future build breakage.)
* Internal change to what API is used for reinterpreting the lane configuration of SIMD vectors.

-* [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.

-## 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.
-
-[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 (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;
- 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.

-computational kernels.

-
-Rust can be more flexible: you can build a single binary/library which automatically

--->
-
-**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.

-# 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!

-
-// 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:
-///
-/// ```
-/// # 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.
-/// # }
-/// ```

-///
-/// ```

-/// # 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)
-//! - [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/)

+# version\_check
+
+[](https://github.com/SergioBenitez/version_check/actions)
+[](https://crates.io/crates/version_check)
+[](https://docs.rs/version_check)
+
+This tiny crate checks that the running or installed `rustc` meets some version
+requirements. The version is queried by calling the Rust compiler with
+`--version`. The path to the compiler is determined first via the `RUSTC`
+environment variable. If it is not set, then `rustc` is used. If that fails, no
+determination is made, and calls return `None`.
+
+## Usage
+
+Add to your `Cargo.toml` file, typically as a build dependency:
+
+```toml
+[build-dependencies]
+version_check = "0.9"
+```
+
+`version_check` is compatible and compiles with Rust 1.0.0 and beyond.
+
+## Examples
+
+Set a `cfg` flag in `build.rs` if the running compiler was determined to be
+at least version `1.13.0`:
+
+```rust
+extern crate version_check as rustc;
+
+if rustc::is_min_version("1.13.0").unwrap_or(false) {
+ println!("cargo:rustc-cfg=question_mark_operator");
+}
+```
+
+Check that the running compiler was released on or after `2018-12-18`:
+
+```rust
+extern crate version_check as rustc;
+
+match rustc::is_min_date("2018-12-18") {
+ Some(true) => "Yep! It's recent!",
+ Some(false) => "No, it's older.",
+ None => "Couldn't determine the rustc version."
+};
+```
+
+Check that the running compiler supports feature flags:
+
+```rust
+extern crate version_check as rustc;
+
+match rustc::is_feature_flaggable() {
+ Some(true) => "Yes! It's a dev or nightly release!",
+ Some(false) => "No, it's stable or beta.",
+ None => "Couldn't determine the rustc version."
+};
+```
+
+See the [rustdocs](https://docs.rs/version_check) for more examples and complete
+documentation.
+
+## Alternatives
+
+This crate is dead simple with no dependencies. If you need something more and
+don't care about panicking if the version cannot be obtained, or if you don't
+mind adding dependencies, see [rustc_version]. If you'd instead prefer a feature
+detection library that works by dynamically invoking `rustc` with a
+representative code sample, see [autocfg].

+//! This tiny crate checks that the running or installed `rustc` meets some
+//! version requirements. The version is queried by calling the Rust compiler
+//! with `--version`. The path to the compiler is determined first via the
+//! `RUSTC` environment variable. If it is not set, then `rustc` is used. If
+//! that fails, no determination is made, and calls return `None`.
+//!
+//! # Examples
+//!
+//! * Set a `cfg` flag in `build.rs` if the running compiler was determined to
+//! be at least version `1.13.0`:
+//!
+//! ```rust
+//! extern crate version_check as rustc;
+//!
+//! if rustc::is_min_version("1.13.0").unwrap_or(false) {
+//! println!("cargo:rustc-cfg=question_mark_operator");
+//! }
+//! ```
+//!
+//! See [`is_max_version`] or [`is_exact_version`] to check if the compiler
+//! is _at most_ or _exactly_ a certain version.
+//!
+//! * Check that the running compiler was released on or after `2018-12-18`:
+//!
+//! ```rust
+//! extern crate version_check as rustc;
+//!
+//! match rustc::is_min_date("2018-12-18") {
+//! Some(true) => "Yep! It's recent!",
+//! Some(false) => "No, it's older.",
+//! None => "Couldn't determine the rustc version."
+//! };
+//! ```
+//!
+//! See [`is_max_date`] or [`is_exact_date`] to check if the compiler was
+//! released _prior to_ or _exactly on_ a certain date.
+//!
+//! * Check that the running compiler supports feature flags:
+//!
+//! ```rust
+//! extern crate version_check as rustc;
+//!
+//! match rustc::is_feature_flaggable() {
+//! Some(true) => "Yes! It's a dev or nightly release!",
+//! Some(false) => "No, it's stable or beta.",
+//! None => "Couldn't determine the rustc version."
+//! };
+//! ```
+//!
+//! * Check that the running compiler supports a specific feature:
+//!
+//! ```rust
+//! extern crate version_check as rustc;
+//!
+//! if let Some(true) = rustc::supports_feature("doc_cfg") {
+//! println!("cargo:rustc-cfg=has_doc_cfg");
+//! }
+//! ```
+//!
+//! * Check that the running compiler is on the stable channel:
+//!
+//! ```rust
+//! extern crate version_check as rustc;
+//!
+//! match rustc::Channel::read() {
+//! Some(c) if c.is_stable() => format!("Yes! It's stable."),
+//! Some(c) => format!("No, the channel {} is not stable.", c),
+//! None => format!("Couldn't determine the rustc version.")
+//! };
+//! ```
+//!
+//! To interact with the version, release date, and release channel as structs,
+//! use [`Version`], [`Date`], and [`Channel`], respectively. The [`triple()`]
+//! function returns all three values efficiently.
+//!
+//! # Alternatives
+//!
+//! This crate is dead simple with no dependencies. If you need something more
+//! and don't care about panicking if the version cannot be obtained, or if you
+//! don't mind adding dependencies, see
+//! [rustc_version](https://crates.io/crates/rustc_version).
