Well, human-generated.

These are things like 

    unsigned RegOp = OpTbl2Addr[i][0];
    unsigned MemOp = OpTbl2Addr[i][1];
    if (!RegOp2MemOpTable2Addr.insert(std::make_pair((unsigned*)RegOp,
                                                     MemOp)).second)

There are several tables that all take unsigned* .   This is safe on any target I'm familiar with since the conversion will not shorten, but it's peculiar.  Seems to go back to Evan's original implementation in 42509, why it is like this?
