gdb/ChangeLog
Update copyright year range in copyright header of all GDB files.
The div and mod eBPF instructions are unsigned, but the semantic
specification for the simulator incorrectly used signed operators.
Correct them to unsigned versions, and correct the ALU tests in
the simulator (which incorrectly assumed signed semantics).
Tested in bpf-unknown-none.
