SIMD subgroup meeting on 2022-03-18

[ngzhian]

This is a joint meeting with flexible-vectors and any SIMD related presentations are also welcome, e.g. new architectures or toolchains, longer term discussion that don't fit into flexible-vectors or relaxed-simd.

The meeting will be on Friday, March 18 at 9:00AM - 10:00AM PDT/ 5:00PM - 6:00PM CET.

If this meeting doesn't already appear on your calendar, or you are a new attendee, please fill out this form to attend.

I would like to:

• share the progress we have made on phase 3 todos
• walk through the prototype spec text
• see how the group feel about polling for phase 3 soon

Officially back this week, will file in flexible vectors in a second.

Fixed https://www.ngzhian.com/relaxed-simd/core/exec/numerics.html based on today's comments:

• missing parens in relaxed fma
• relaxed fms now calls relaxed fma with negated third input
• relaxed min/max cases for nans allow is more closely aligned with min/max (allow for arithmetic nan results), the previous definition was too strict (required nan payloads to match exactly, such that min/max was not a valid implementation of relaxed min/max)

Also added an agenda item for next CG meeting WebAssembly/meetings#998 2022-03-29 to give an update to the CG and poll for phase 3.

Next meeting is #68

Also added an agenda item for next CG meeting WebAssembly/meetings#998 2022-03-29 to give an update to the CG and poll for phase 3.

This will probably be cancelled as there is only 1 agenda item, I will prepare and give an update at the next CG meeting (already on next meeting's agenda https://github.com/WebAssembly/meetings/blob/main/main/2022/CG-04-12.md)
