This is going to be a bit grisly: the Arm v7 Neon registers flush subnormals and Rust has defined floats as to deny flushing subnormals to be a valid behavior. If we want std::simd to align here with …

I've started making series of Pull Requests for .NET 8 update.
- [x] Update global.json, dockerfile, and some packages which does not need code fixes.
- #1726
- [x] Update stylecop.

At the moment there's the `llvm_intrinsically_optimized!` macro which, when using the unstable flag, will call an unstable LLVM intrinsic.
However, there's some opportunities for using intrinsics (…

# Introduction
Concept of a HAL (Hardware Abstraction Layer) is well-known. Basically it means that in some big software package (library of algorithms, operating system, photo editing application …

### Background and motivation
`VPCLMULQDQ` is supported by Intel in the Ice Lake and newer architectures, and by AMD in Zen 4. It allows for parallel `pclmulqdq` in `Vector256` and `Vector512` and is…

The floating-point formatting/parsing code currently uses an internal `BigInteger` ref struct that would likely benefit from using specific hardware intrinsics.
We should investigate using the BMI …

### Background and motivation
Now the GCC had merged the LoongArch's SIMD.

There are a few places in the code-base where `FEATURE_HW_INTRINSICS` functionality is dependent on `FEATURE_SIMD` also being defined.
The hardware intrinsics feature should (ideally) share code wi…

HW intrinsics project is approaching a point where it will be possible to write real life code using available ISAs. This should allow to validate intrinsics implementation using complex functionality…

As of dotnet/coreclr#8235, RyuJIT/x86 imports intrinsics that are not supported by the target as calls to user functions. This has an obvious CQ downside in that it prohibits the compiler from reasoni…
