This series is intended to fix ARM watchpoint emulation misbehavior.
QEMU hangs when QEMU watchpoint fires but it does not pass additional
architectural checks in ARM CPU debug exception handler. For details,
please see individual patches. The most relevant parts of the original
discussion about ARM breakpoint and watchpoint emulation misbehavior can be
found at:
https://lists.gnu.org/archive/html/qemu-devel/2015-08/msg02715.html
https://lists.gnu.org/archive/html/qemu-devel/2015-09/msg00527.html
Changes in v2:
* Check moved before setting cpu->watchpoint_hit
* Pointer to watchpoint being checked passed to debug_check_watchpoint()
callback
* Comment for debug_check_watchpoint() callback improved
Sergey Fedorov (2):
cpu: Add callback to check architectural watchpoint match
target-arm: Implement checking of fired watchpoint
