wasm NEON and AltiVec: add u16x8 and u8x16 avgr translations #1206

Closed wrv closed 3 weeks ago

wrv commented 3 weeks ago

This PR provides WASM to NEON translations from wasm_u16x8_avgr to vrhaddq_u16 and wasm_u8x16_avgr to vrhaddq_u8.

I also tested these locally on a Mac Mini M1.

Something worth noting here is that the AltiVec translation may also work, but I haven't tested it on a physical device. Here is what that change looks like: https://github.com/wrv/simde/commit/ff4e85ac47e538aff820514ff728ca3fa6382a9a And the GH Actions result on that change: https://github.com/wrv/simde/actions/runs/10461140123

If that looks alright, I can add it to this PR.
