Description

Please confirm if the intended behavior for reference-typed WebAssembly.Global is the following:

  • new WebAssembly.Global({ "value": "anyfunc", "mutable": true}).value == null
  • new WebAssembly.Global({ "value": "anyfunc", "mutable": true}, undefined) throws TypeError
  • new WebAssembly.Global({ "value": "externref", "mutable": true}).value == undefined

and the omitted/undefined value behaves the same for table.new, table.set, table.grow.
