Overview

We achieved parity with x64 for Arm64 intrinsics support in .NET 5 for most of them except for multi-register intrinsics. We need more work to enable multi-register intrinsics for Arm64. The work is integral in that it involves changes in JIT, libraries and mono to enable working intrinsics.

Work Items

Benchmarks to use

  • Microbenchmarks

What Success Looks Like

  • Improve the performance of the defined microbenchmarks
  • Advertise the feature to the community, e.g., through blog posts or twitter

Moved to .NET 8

  • Enable multi-register intrinsics support for Arm64 (such as ones that will expose LD1 or TBL instructions)
