Peter Maydell 2472b6c07b gdbstub: Allow target CPUs to specify watchpoint STOP_BEFORE_ACCESS flag ... GDB assumes that watchpoint set via the gdbstub remote protocol will behave in the same way as hardware watchpoints for the target. In particular, whether the CPU stops with the PC before or after the insn which triggers the watchpoint is target dependent. Allow guest CPU code to specify which behaviour to use. This fixes a bug where with guest CPUs which stop before the accessing insn GDB would manually step forward over what it thought was the insn and end up one insn further forward than it should be. We set this flag for the CPU architectures which set gdbarch_have_nonsteppable_watchpoint in gdb 7.7: ARM, CRIS, LM32, MIPS and Xtensa.
