- Log message:
- Execute trapped instruction after breakpoint is removed
Closes bug #104
When the instruction replaced by a trap instruction is restored by the
debugger, this instruction is not executed.
Proposed solution:
- Checked for a debug unstall condition plus a trap condition in
or1200_du(dbg_stall && |except_stop).
- Then, when this event occur, flush the entire pipeline (in or1200_ctrl) and
set the pc to npc in or1200_genpc(which is equal to the trapped instruction
address).
