This makes two changes to prepare for incoming changes to skwasm in the web engine:

  • We will (at least for now) be depending on the WebAssembly.Function constructor in skwasm, which is hidden behind the --experimental-wasm-type-reflection flag. We need to pass that when running skwasm benchmarks.
  • We are going to be upgrading the skwasm build to a newer version of emscripten, which exposes the wasm exports via the wasmExports property instead of the asm property. Make sure to support either, if passed.

It looks like this pull request may not have tests. Please make sure to add tests before merging. If you need an exemption to this rule, contact Hixie on the #hackers channel in Chat (don't just cc him here, he won't see it! He's on Discord!).

If you are not sure if you need tests, consider this rule of thumb: the purpose of a test is to make sure someone doesn't accidentally revert the fix. Ask yourself, is there anything in your PR that you feel it is important we not accidentally revert back to how it was before your fix?

Reviewers: Read the Tree Hygiene page and make sure this patch meets those guidelines before LGTMing.

Minor suggestion: if it were me, I would probably do it this way:

Suggested change
final String jsFlags = options.enableWasmGC ? <String>[
'--experimental-wasm-gc',
'--experimental-wasm-type-reflection',
].join(' ') : '';
const String kWasmGCFlags =
'--experimental-wasm-gc '
'--experimental-wasm-type-reflection';

Then below:

if (options.enableWasmGC) '--js-flags=$kWasmGCFlags';

But this is just my personal preference.

I did it this way because I feel like the join call is less error prone than trying to remember to put spaces in the right places in the string yourself. It's the same pattern we use in the compile unit tests step in the engine, which is where I copied it from. When we've had to change which flags are being added, it's a little simpler to just add or remove a flag from this list than to try to reason about how the string is going to be constructed.
