Nope. You take a debug exception; the syndrome register tells
you if it was a bp or a wp, and if it was a wp the fault address
register tells you the address being accessed (if it was a bp
you know the program counter, obviously). The debugger is expected
to be able to figure it out from there, if it cares.
