I believe that you are not strictly correct. Perhaps you meaning that they would not intentionally ship parts that did not execute all codes correctly. It is simply not possible to know or test this. Is it not true that multliply not work on a Intel chip? Is not this an X86 instruction? All shippng CPUS have some bugs known by the manufacturer. The multiply bug was a critical one, but most are benign. Most of the bugs in production CPUS are not op-codes that execute incorrrectly, but rather hardware related. However, in prototype CPUS you may still see op-code errors in esoteric functions.
