This presentation describes one way to extend Wasm SIMD, by defining longer (flexible) vectors in the spirit of existing Wasm semantics. This has been presented at a Wasm SIMD sync call at 2019-11-06.

Provide length-agnostic operations to support various SIMD hardware.
While true vector instruction sets are an interesting topic, they are not yet widespread enough in consumer hardware to warrant a WebAssembly proposal. Should they become widespread, this can be extended to support them.
This proposal is also not about modifying existing WebAssembly SIMD proposal - simd128 is a very mature proposal that inspired this work, but it has uses and implementations and it would not be worth holding it up to test out an early-stage idea.
Runtime SIMD wrappers:
- Highway
- System.Numerics.Vector in .NET
Build prerequisites are texlive and beamer; source should be recognized by most TeX editors. To build using GNU make:
$ make
