Hi @MaskRay , I'm also confused why SystemZ is supposedly doing anything special here.  The only use of the `Address` argument to `getInstruction` in the SystemZ implementation is to pass it on to `MCDecoder::tryAddingSymbolicOperand`, which looks to be exactly the same that most other targets do as well.

Also, there seem to be several other calls to `getInstruction` in llvm-objdump.cpp - don't they also need to pass the adjusted address`
