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... Preliminary performance data that motivated the proposal: https://github.com/WebAssembly/simd/pull/79 Thanks, Deepti
