the mips sim port is garbage in many ways.  you've found another one.
it's full of unstated variable names like assuming "SD" is the variable
name everywhere, as is "CPU".  it largely comes from the igen source.

looks like i broke this while trying to clean up the global state refs
in the mips sim.  the current_state was a global pointer to the sd that
is passed around that i punted.

at any rate, should be fixed now in master & the gdb-7.12 branch.
