RiceTea.Backport.System.Runtime.Intrinsics

Provides APIs for accessing processor specific instructions. (backports to .NET Standard 2.0 by Rice Tea)

Only implements those APIs that I may use

Provides those types and methods:

• System.Runtime.Intrinsics.X86.Bmi1
  • TrailingZeroCount
• System.Runtime.Intrinsics.X86.Bmi1.X64
  • TrailingZeroCount
• System.Runtime.Intrinsics.X86.Lzcnt
  • LeadingZeroCount
• System.Runtime.Intrinsics.X86.Lzcnt.X64
  • LeadingZeroCount
• System.Runtime.Intrinsics.X86.Popcnt
  • PopCount
• System.Runtime.Intrinsics.X86.Popcnt.X64
  • PopCount
• System.Runtime.Intrinsics.X86.X86Base
  • CpuId
  • BitScanForward
  • BitScanReverse
  • DivRem
  • Pause
• System.Runtime.Intrinsics.X86.X86Base.X64
  • CpuId
  • BitScanForward
  • BitScanReverse
  • DivRem
