1865164 - (wasm-flexible-vectors) [meta] Flexible Vectors Wasm proposal

Status: NEW

(Core :: JavaScript: WebAssembly, enhancement, P3)

Description

[Yury Delendik (:yury)]

Consider implementing Flexible Vectors Proposal for WebAssembly https://github.com/WebAssembly/flexible-vectors . Current Wasm SIMD operations are limited to 128 bit. With availability of Intel AVX2/AVX512 and ARM SVE, it will be nice to increase size of operands/registers for vector operations.

Initial and naive implementation in SpiderMonkey can just map/alias flexible vector operations to the existing Wasm SIMD (and add few more). Basically case of vec.i8.length := 16.

The meta keyword is there, the bug doesn't depend on other bugs and there is no activity for 12 months.
:rhunt, maybe it's time to close this bug?
