SIMD support is musted? about wasm-vips HOT 3 OPEN

FYI it seems likely that Safari will support SIMD in version 16.3 sometime in February/March. At that stage, all engines support the feature 🥳

Hello, the pre-built binaries currently requires an engine that supports Wasm SIMD. However, you can still build binaries without this feature, by passing the --disable-simd build parameter.

Assuming you have Docker installed (or another OCI-compliant container runtime, such as Podman) and using a Unix-like environment (otherwise $(pwd) does not work), you can use the build command available in package.json.

For example:

$ npm run build -- --disable-simd

There's a possibility that I can provide pre-built binaries that does not use SIMD as a fallback (e.g., for compatibility with Safari, which at the time of writing does not support that). However, I don't know if that makes sense, given that Wasm SIMD is standardized, and is likely to become a mandatory feature in Wasm 2.0.

FWIW, I'm also planning to make use of the standardized reference types feature, which is enabled by default on V8-based engines after commit v8/v8@1771e4a (corresponds to V8 9.9.2, Chrome 96, Node.js 18.0.0, Deno 1.20.0). It's a bit too early to enable that and should happen after Node 16.x reaches EOL. Fortunately, this feature is supported by Safari and should already be safe to enable on Firefox (supported since version 79, so that doesn't require increasing the minimum version).

Thx for your reply.
I will try to build the no simd version according to the method you said.

In my region, for some reason, chrome is not popular, replaced by various custom browsers based on chromium.
And these browsers don't seem to care about updating the chromium version, so we have a large number of users using outdated browsers (nearly 80% of people use the chrome86 kernel version of the browser).
That's why I need the no simd version.
