Hi all. I am running simulations with Simics over a Solaris-Sparc
simulated machine. I have the following problems:

if I load ruby and opal modules into simics and I run simulation using
opal command opal0.sim-step N (where N is an integer number of
istructions to execute), if the simulation "encounters" a
MAGIC_BREAKPOINT (that is, over Sparc, the instruction sethi 0x40000,
%g0), simulation is correctly interrupted, but it seems impossible to
continue it again (using both "continue" or opal0.sim-step). I tried
to unload opal, but it seems impossible. I have read on the mailing
list that another user had the same problem.
Does anyone know what's wrong and how to solve the problem?

Sorry to be a nuisance.
Thank you very much.
