Currently the only place V8 does this is asm.js compilation:

function AsmModule() {
  'use asm';

  function add(a, b) {
    a = a | 0;
    b = b | 0;

    // should be `return (a + b) | 0;`
    return a + b; // (node:18940) V8: test.js:9 Invalid asm.js: Invalid return type
  }

  return { add: add };
}

In chromium:

Checklist
  • make -j4 test (UNIX), or vcbuild test (Windows) passes
  • tests and/or benchmarks are included
  • commit message follows commit guidelines

Is it testable? Maybe with a message test?

Would you mind adding the test case from the PR description as a test here?

refack added the wasm label

I know it's not wasm but it's the most relevant label.

It would probably be even better if ProcessEmitWarningGeneric is less generic on the C++ side and we can just do the overload in JS...but anyway LGTM

(off-topic: we have a wasm label? AND a asm.js label? and they are both green?)

The asm.js is brand new. And like their subjects, if you look from a distance they look the same ;)

@devsnek do you think that this can/should be backported to v10.x? I added the label but feel free to remove!

test: remove test-node-output-v8-warning
e2ad744 
asm.js validation is deprecated and disabled by default in V8,
so there's no longer a stable user-reachable trigger for
`v8::Isolate::kMessageWarning`. Remove the test.
