1. What are the instructions being proposed? #148

Closed HxYxI closed 1 year ago

HxYxI commented 1 year ago

  1. What are the instructions being proposed?

  2. What are the semantics of these instructions?

  3. How will these instructions be implemented? Give examples for at least x86-64 and ARM64. Also provide reference implementation in terms of 128-bit Wasm SIMD.

  4. How does behavior differ across processors? What new fingerprinting surfaces will be exposed?

  5. What use cases are there?
