I just realised that I never commented on this PR. Sorry about that! I think the functionality is subsumed by now, so I'm closing. Please feel free to reopen if you think there's something missing still. |

Packed data is not defined anywhere. We can specify SIMD as a i128 (128-bit integer). Later when specifying the SIMD instructions, we can use some "expansions" to expand i128 into the required lane shapes. Also, use v128 instead of s128, v128 is already commonly used in many places in this proposal, in the BinarySIMD.md, SIMD.md, and reference interpreter.

As discussed in #202 The JS tag was added to the JS API spec in #301, but it is not observable. This change exposes it on the WebAssembly namespace, allowing it to be imported into wasm modules. This allows wasm modules to explicitly extract the thrown JS objects as externrefs from the caught exrefs, and also to throw fresh exceptions with externref payloads that will propagate into JS and can be caught as bare JS objects not wrapped in a WebAssembly.Exception. It also places the restriction that WebAssembly.Exception objects cannot be created with the JS tag, because it would result in ambiguity or asymmetry when such objects unwind from JS into wasm and back out.

I tried to tidy up the "show module signatures" mode since it wasn't indented at all and was lacking information about the memory size and (probably more important) information about imported functions.
Since we seem to get support for the binary format in the near future, it seemed to me, that some little summarizing functionality could come in handy.
This is what its output looks like:
