Function insert_interrupt 

pub fn insert_interrupt(
    ctx: &mut Context<'static>,
    block: BlockId,
    before: Option<InstructionId>,
    address: Option<u64>,
    code: u64,
    args: &[ValueId],
) -> InstructionId

Inserts vm.interrupt(code, args...) into block, before before or at the block’s start when before is None. The op declares no result and is stamped with guest address address, which is what the interrupt then reports as its pc. args are any values visible at that point.
