2015-11-15 Mike Frysinger <vapier@gentoo.org>
* cr16_sim.h (cr16_callback): Delete.
* interp.c (cr16_callback): Delete.
(do_run): Delete cr16_callback. Replace
cr16_callback->printf_filtered with sim_io_printf.
(sim_open): Delete cr16_callback assignment.
(step_once, sim_create_inferior): Replace
cr16_callback->printf_filtered with sim_io_printf.
* simops.c (move_to_cr, trace_input_func, do_trace_output_flush,
do_trace_output_finish, trace_output_40, trace_output_32,
trace_output_16, trace_output_void, trace_output_flag): Replace
cr16_callback->printf_filtered with sim_io_printf and
cr16_callback->flush_stdout with sim_io_flush_stdout.
(OP_14C_14): Likewise. Rename cr16_callback to cb.
2015-11-15 Mike Frysinger <vapier@gentoo.org>
* Makefile.in (SIM_OBJS): Add sim-reason.o, sim-resume.o, and
