Next SIMD subgroup meeting is on 11th of June, link to sign up and details are in WebAssembly/relaxed-simd#23. Agenda is topics related to SIMD or vector operations in WebAssmebly, not limited to this proposal.

A couple of topics:

Opcodes for flexible vectors, https://github.com/WebAssembly/flexible-vectors/issues/34#issuecomment-854332138
I am curious about hardware discovery in context of relaxed simd, in case @Maratyszcza is available: https://github.com/WebAssembly/relaxed-simd/issues/11#issuecomment-842688719

I would like to discuss performance expectations for instructions we want in relaxed-simd.

penzn commented 3 years ago

@ngzhian I think you should start with your topic.

Another minor item from me is the eliding of and before lane shift (and other SIMD instructions that do an and on their operands).
