Description

Hello everybody, in this pull request I am implementing the proposed API to #54390 by @tannergooding.

Feel free to leave your feedback :).

Proposed API

namespace System.Numerics
{
    public static partial class BitOperations
    {
        public static bool IsPow2(nint value);
        public static bool IsPow2(nuint value);

        public static nuint RoundUpToPowerOf2(nuint value);

        public static int LeadingZeroCount(nuint value);

        public static int Log2(nuint value);

        public static int PopCount(nuint value);

        public static int TrailingZeroCount(nint value);
        public static int TrailingZeroCount(nuint value);

        public static nuint RotateLeft(nuint value, int offset);
        public static nuint RotateRight(nuint value, int offset);
    }
}

Proposal of @tannergooding

Why does the Test Runner say that the methods do not exist?

Why does the Test Runner say that the methods do not exist?

@deeprobin Don't forget to update the ref assembly (https://raw.githubusercontent.com/dotnet/runtime/main/src/libraries/System.Runtime/ref/System.Runtime.cs). Easiest way to update it would probably be to look at how the other BitOperations API stubs are exposed, then copy + paste those as new lines, renaming methods and parameters as needed.

Better still to use the tool so there's no extra diffs:

The tool does not seem to work for me :/.

E:\dotnet\runtime>cd src

E:\dotnet\runtime\src>dotnet msbuild /t:GenerateReferenceAssemblySource
Could not execute because the application was not found or a compatible .NET SDK is not installed.
Possible reasons for this include:
  * You intended to execute a .NET program:
      The application 'msbuild' does not exist.
  * You intended to execute a .NET SDK command:
      A compatible installed .NET SDK for global.json version [6.0.100-rc.1.21430.12] from [E:\dotnet\runtime\global.json] was not found.
      Install the [6.0.100-rc.1.21430.12] .NET SDK or update [E:\dotnet\runtime\global.json] with an installed .NET SDK:
        5.0.102 [C:\PROGRA~1\dotnet\sdk]
        6.0.100-preview.7.21379.14 [C:\PROGRA~1\dotnet\sdk]

E:\dotnet\runtime\src>

@GrabYourPitchforks Thank you, I manually updated the ref assembly in the last commit.

Try using the dotnet at the root of the repo. It pulls down and uses the correct one. Alternatively it should fix it if you install the RC1 SDK
