Bug #165282 is getting huge, and already tests interesting things and gets the useful functionality off the ground. We should go back and test other weird corner cases. I left some FIXMEs in wasm-to-wasm.js to test other interesting things: // FIXME: test wasm->wasm using 32-bit things (including float), as well as 64-bit NaNs that don't get canonicalized // FIXME: do a throw two-deep // FIXME: check that the first wasm's instance is back in OK state (with table or global?) // FIXME: test calling through a Table
