What is wrong?

Adding certain custom functions causes the error: Uncaught Error: argument bit ratio not found

Where does it happen?

Not system specific

How do we replicate the issue?

<script>
const gpu = new GPU()

gpu.addFunction(function f(x, y) {
    return y[0]
})

const test = gpu.createKernel(function (a) {
    f(1, a)
}).setOutput([4, 4]).setGraphical(true)

test([0])
</script>

Setting setGraphical(true) causes the error for some reason

How important is this (1-5)?

3 or 4 maybe?

Expected behavior (i.e. solution)

No error

Other Comments

In FunctionBuilder.assignArgumentBitRatio, replacing calleeNode.argumentBitRatios[i] with calleeNode.argumentBitRatios[argumentIndex] should fix the problem.

Also, why does having a blank return statement cause an error

const test = gpu.createKernel(function () {
    // stuff
    return
}).setOutput([4, 4]).setGraphical(true)
test() // Uncaught Error: Unexpected return statement on ...

when there is no error with having no return statements

const test = gpu.createKernel(function () {
    // stuff
}).setOutput([4, 4]).setGraphical(true)
test()
