Microsoft highlights .NET 8 Hardware Intrinsics features
(11 December 2023)

• SVE and SVE2 for Arm64
• AVX10 for x86/x64
• Allowing Vector<T> to implicitly expand to 512-bits
• An ISimdVector<TSelf, T> interface to allow better reuse of SIMD logic
• An analyzer to help encourage users to use the cross-platform APIs where the semantics are identical (use x + y instead of Sse.Add(x, y))
• An analyzer to recognize patterns that may have more optimal alternatives (do value + value instead of value * 2 or Sse.UnpackHigh(value, value) instead of Sse.Shuffle(value, value, 0b11_11_10_10)
• Additional explicit usage of hardware intrinsics in various .NET APIs
• Additional cross-platform APIs to help abstract common operation
  • getting the index of the first/last match in a mask
  • getting the number of matches in a mask
  • determining if any matches exist
  • allowing non-deterministic behavior for cases like Shuffle or ConditionalSelect
  • these APIs have a well-defined behavior on all platforms today, such as Shuffle treating any out of range index as zeroing the destination element
  • the new APIs, such as ShuffleUnsafe, would instead allow different behavior for out of range indices
  • for such a scenario, Arm64 would have the same behavior, while x64 only has the same behavior if the most-significant bit is set
• Additional pattern recognition for cases like
  • embedded masking (AVX512, AVX10, SVE/SVE2)
  • combined bitwise-operations (vpternlog on AVX512)
  • limited JIT time constant folding opportunities
