of rewriting gdb, none of them seem to work. Thus,

for now, we assume that a hardware breakpoint will

it executes the instruction, thus, when the breakpoint

vector returns, it will return to the same instruction

that caused the exception (and thus hit the exception

again if it hasn't been cleared) Note that if it actually

executes this instruction, things fail bandly inside of

gdb. This should not be an issue for now, as the or1200
