Creating a WasmModuleBuilder in V8 that enables functions to return multiple values

I'm currently working on creating a wasm function using WasmModuleBuilder from V8:

var builder = new WasmModuleBuilder();
builder.addMemory(5, 5, false);
builder.addFunction("func", {params: [125,125], results: [125,125]});
builder.functions[0].addBody([
                       kExprGetLocal,
                       0,
                     kExprGetLocal,
                      1
          ]);
          x = builder.instantiate()
          for (f in x.exports) {
                console.log(x.exports[f](0.5, 0.5))
            }

An error is being thrown:

asm decoding failed: return count of 2 exceeds internal limit of 1 @+15

I'm looking for a way to return multiple values. Any suggestions or alternative methods for creating wasm functions from JavaScript code would be greatly appreciated.

Answer №1

It is my understanding that the WasmModuleBuilder has not been updated to handle multiple values at this time. I recommend submitting an issue report for further assistance.
