1648697 - Neuter the --enable-avx flag and remove from fuzz-flags.txt

Status: RESOLVED FIXED

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

Description

[Lars T Hansen [:lth]]

We currently do not support avx encodings at all and it's easy to run into problems when asking for them, so let's remove the ability to ask for them until we want to start worrying about them.

Attachment: Bug 1648697 - Disable --enable-avx. r?bbouvier

I disable this with an error message and a comment, but do not remove it,
because it is currently buggy and unsupported but may well make a comeback
when we have time to clean it up and we see whether wasm SIMD on the web
starts demanding it.

It is of course possible that we will never do this in Ion but will wait
for Cranelift, but we don't have to make that decision today.
