Thu Sep 4 10:48:57 1997 Andrew Cagney <cagney@b1.cygnus.com>
* sim-calls.c (sim_open): Use sim_do_command to add memory, only
add memory if none already present.
(sim_open): Move init of registers from here.
(sim_create_inferior): To here. Init modules.
* Makefile.in (SIM_OBJS): Add sim-memopt.o module.
* sim-calls.c (sim_open): Add zero modulo arg to sim_core_attach.
