At the start of the function, the arguments are assumed to be initialized but the results are assumed uninitialized. If the results will hold live pointers during a call instruction, the function should start by zeroing the results and then executing the pseudo-instruction <code>GO_RESULTS_INITIALIZED</code>. This instruction records that the results are now initialized and should be scanned during stack movement and garbage collection.
