+# 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.)

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.

-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.
|
|

-# 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].
|
|

|
|
-[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.

-# 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].

-# 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 |

-
|
|
-## 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!

-/// 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`.

-/// 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));

|
|
-//!
|
|
-//! ## 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/)
