[Qemu-devel] [PATCH v2 0/2] target-arm: Fix breakpoint handling

[Sergey Fedorov]

This series is intended to fix ARM breakpoint emulation misbehavior.
QEMU hangs when QEMU breakpoint 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 emulation misbehavior can be found at:
https://lists.gnu.org/archive/html/qemu-devel/2015-08/msg02715.html

Changes in v2:
 * The initial commit split into two parts
 * Extra block eliminated in arm_debug_excp_handler()
 * Just one instruction always translated in case of breakpoint PC match
