Background and Motivation

Over the past few releases of .NET Core (now called just .NET), we have released a set of APIs called hardware intrinsics that provide access to platform/architecture specific functionality in order to allow developers the ability to accelerate their code. This started with x86/x64 support in .NET Core 3 and was extended with Arm64 support in .NET 5.

WASM is also looking at providing SIMD support and currently has a nearly complete, but not yet approved, draft specification: https://github.com/WebAssembly/simd/blob/main/proposals/simd/SIMD.md. As such, we should look at adding the relevant APIs to support this platform and to eventually tie it into the "cross platform" helpers so we can trivially light up our existing code paths to also run on WASM: #49397

-- This could be reviewed, approved, and implemented using the [RequiresPreviewFeatures] attribute as most browsers have some experimental support for the feature already: https://github.com/WebAssembly/simd/blob/main/proposals/simd/ImplementationStatus.md. It would then become stable, with the relevant fixups, when the spec becomes finalized.

    8.0.0
    Description
    @tannergooding
    tannergooding
    opened on Jun 4, 2021
    Background and Motivation
    Over the past few releases of .NET Core (now called just .NET), we have released a set of APIs called hardware intrinsics that provide access to platform/architecture specific functionality in order to allow developers the ability to accelerate their code. This started with x86/x64 support in .NET Core 3 and was extended with Arm64 support in .NET 5.
    WASM is also looking at providing SIMD support and currently has a nearly complete, but not yet approved, draft specification: https://github.com/WebAssembly/simd/blob/main/proposals/simd/SIMD.md. As such, we should look at adding the relevant APIs to support this platform and to eventually tie it into the "cross platform" helpers so we can trivially light up our existing code paths to also run on WASM: #49397
    -- This could be reviewed, approved, and implemented using the [RequiresPreviewFeatures] attribute as most browsers have some experimental support for the feature already: https://github.com/WebAssembly/simd/blob/main/proposals/simd/ImplementationStatus.md. It would then become stable, with the relevant fixups, when the spec becomes finalized.

      Description

      opened on Jun 4, 2021
      Background and Motivation
      Over the past few releases of .NET Core (now called just .NET), we have released a set of APIs called hardware intrinsics that provide access to platform/architecture specific functionality in order to allow developers the ability to accelerate their code. This started with x86/x64 support in .NET Core 3 and was extended with Arm64 support in .NET 5.
      WASM is also looking at providing SIMD support and currently has a nearly complete, but not yet approved, draft specification: https://github.com/WebAssembly/simd/blob/main/proposals/simd/SIMD.md. As such, we should look at adding the relevant APIs to support this platform and to eventually tie it into the "cross platform" helpers so we can trivially light up our existing code paths to also run on WASM: #49397
      -- This could be reviewed, approved, and implemented using the [RequiresPreviewFeatures] attribute as most browsers have some experimental support for the feature already: https://github.com/WebAssembly/simd/blob/main/proposals/simd/ImplementationStatus.md. It would then become stable, with the relevant fixups, when the spec becomes finalized.
      Proposed API

        Description
        @tannergooding
        tannergooding
        opened on Jun 4, 2021
        Background and Motivation
        Over the past few releases of .NET Core (now called just .NET), we have released a set of APIs called hardware intrinsics that provide access to platform/architecture specific functionality in order to allow developers the ability to accelerate their code. This started with x86/x64 support in .NET Core 3 and was extended with Arm64 support in .NET 5.
        WASM is also looking at providing SIMD support and currently has a nearly complete, but not yet approved, draft specification: https://github.com/WebAssembly/simd/blob/main/proposals/simd/SIMD.md. As such, we should look at adding the relevant APIs to support this platform and to eventually tie it into the "cross platform" helpers so we can trivially light up our existing code paths to also run on WASM: #49397
        -- This could be reviewed, approved, and implemented using the [RequiresPreviewFeatures] attribute as most browsers have some experimental support for the feature already: https://github.com/WebAssembly/simd/blob/main/proposals/simd/ImplementationStatus.md. It would then become stable, with the relevant fixups, when the spec becomes finalized.

          opened on Jun 4, 2021
          Background and Motivation
          Over the past few releases of .NET Core (now called just .NET), we have released a set of APIs called hardware intrinsics that provide access to platform/architecture specific functionality in order to allow developers the ability to accelerate their code. This started with x86/x64 support in .NET Core 3 and was extended with Arm64 support in .NET 5.
          WASM is also looking at providing SIMD support and currently has a nearly complete, but not yet approved, draft specification: https://github.com/WebAssembly/simd/blob/main/proposals/simd/SIMD.md. As such, we should look at adding the relevant APIs to support this platform and to eventually tie it into the "cross platform" helpers so we can trivially light up our existing code paths to also run on WASM: #49397
          -- This could be reviewed, approved, and implemented using the [RequiresPreviewFeatures] attribute as most browsers have some experimental support for the feature already: https://github.com/WebAssembly/simd/blob/main/proposals/simd/ImplementationStatus.md. It would then become stable, with the relevant fixups, when the spec becomes finalized.
          Proposed API

            opened on Jun 4, 2021
            Background and Motivation
            Over the past few releases of .NET Core (now called just .NET), we have released a set of APIs called hardware intrinsics that provide access to platform/architecture specific functionality in order to allow developers the ability to accelerate their code. This started with x86/x64 support in .NET Core 3 and was extended with Arm64 support in .NET 5.
            WASM is also looking at providing SIMD support and currently has a nearly complete, but not yet approved, draft specification: https://github.com/WebAssembly/simd/blob/main/proposals/simd/SIMD.md. As such, we should look at adding the relevant APIs to support this platform and to eventually tie it into the "cross platform" helpers so we can trivially light up our existing code paths to also run on WASM: #49397
            -- This could be reviewed, approved, and implemented using the [RequiresPreviewFeatures] attribute as most browsers have some experimental support for the feature already: https://github.com/WebAssembly/simd/blob/main/proposals/simd/ImplementationStatus.md. It would then become stable, with the relevant fixups, when the spec becomes finalized.
            Proposed API

              opened on Jun 4, 2021
              Background and Motivation
              Over the past few releases of .NET Core (now called just .NET), we have released a set of APIs called hardware intrinsics that provide access to platform/architecture specific functionality in order to allow developers the ability to accelerate their code. This started with x86/x64 support in .NET Core 3 and was extended with Arm64 support in .NET 5.
              WASM is also looking at providing SIMD support and currently has a nearly complete, but not yet approved, draft specification: https://github.com/WebAssembly/simd/blob/main/proposals/simd/SIMD.md. As such, we should look at adding the relevant APIs to support this platform and to eventually tie it into the "cross platform" helpers so we can trivially light up our existing code paths to also run on WASM: #49397
              -- This could be reviewed, approved, and implemented using the [RequiresPreviewFeatures] attribute as most browsers have some experimental support for the feature already: https://github.com/WebAssembly/simd/blob/main/proposals/simd/ImplementationStatus.md. It would then become stable, with the relevant fixups, when the spec becomes finalized.
              Proposed API

                Background and Motivation
                Over the past few releases of .NET Core (now called just .NET), we have released a set of APIs called hardware intrinsics that provide access to platform/architecture specific functionality in order to allow developers the ability to accelerate their code. This started with x86/x64 support in .NET Core 3 and was extended with Arm64 support in .NET 5.
                WASM is also looking at providing SIMD support and currently has a nearly complete, but not yet approved, draft specification: https://github.com/WebAssembly/simd/blob/main/proposals/simd/SIMD.md. As such, we should look at adding the relevant APIs to support this platform and to eventually tie it into the "cross platform" helpers so we can trivially light up our existing code paths to also run on WASM: #49397
                -- This could be reviewed, approved, and implemented using the [RequiresPreviewFeatures] attribute as most browsers have some experimental support for the feature already: https://github.com/WebAssembly/simd/blob/main/proposals/simd/ImplementationStatus.md. It would then become stable, with the relevant fixups, when the spec becomes finalized.
