GDB registers unaligned watchpoint hits on the 64-bit ARM architecture
Previously, the *GDB* debugger provided only limited support for unaligned hardware watchpoints used by the "watch", "rwatch", and "awatch" *GDB* commands on the 64-bit ARM architecture. As a consequence, *GDB* running on such systems failed to register some watchpoint hits and subsequently did not stop the debugged program.
*GDB* has been extended to handle this situation. As a result, it can correctly handle any hardware watchpoints on the 64-bit ARM architecture, including unaligned ones.
