[webkit-dev] Request for position: WebAssembly Relaxed SIMD

[Deepti Gandluri]

Hi webkit-dev,

The WebAssembly Relaxed SIMD proposal introduces new vector operations that
take advantage of widely available instruction sets to accelerate compute
workloads. The proposal relaxes the strict portability constraints of
the fixed-width
SIMD proposal
<https://github.com/WebAssembly/simd/tree/master/proposals/simd>. We're
hoping to ship this in Chrome 105/106 contingent on a Phase 4
<https://github.com/WebAssembly/proposals#phase-4---standardize-the-feature-wg>
(currently
at Phase 3) vote in the Wasm CG, requesting a WebKit position for the
proposal.

Proposal: https://github.com/WebAssembly/relaxed-simd
Spec: https://github.com/WebAssembly/relaxed-simd/tree/main/document/core
Implementation status (V8, SpiderMonkey):
https://github.com/WebAssembly/relaxed-simd/blob/main/proposals/relaxed-simd/ImplementationStatus.md
Preliminary performance data that motivated the proposal:
https://github.com/WebAssembly/simd/pull/79

Thanks,
Deepti
