Hi @alannnna, Totally reasonable to extend this. I don’t think we have a doc here on what to do, but off the top of my head it should be as simple as:

Update Interpreter::isOpSupported() to include ElemKind::Int32ITy

Update BoundInterpreterFunction::fwdElementExpInst() to support it
(probably not necessary) May need to update SelectNode::verify() if there is any verification that fails
