Changeset 9037:8a7aa00b20a4 --------------------------- X86: Ensure that the decoder's internal ExtMachInst is completely initialized. There are some bits of some fields of the ExtMachInst which are not actually used for anything but are included in the hash of an ExtMachInst for simplicity and efficiency. This change makes sure the decoder's internal working ExtMachInst is completely initialized, even these unused bits, so that there isn't any nondeterministic behavior, no valgrind messages about uninitialized variables, and no potential false misses/redundant entries in the decode cache.
