2015-12-30 Mike Frysinger <vapier@gentoo.org>
* compile.c (lvalue): Change sim_engine_set_run_state calls to
sim_engine_halt. Declare local cpu.
(fetch_1): Likewise.
(store_1): Likewise.
(sim_resume): Rename to ...
(step_once): ... this. Declare init1, poll_count, reason, and
sigrc variables. Delete step checking. Change
sim_engine_set_run_state calls to sim_engine_halt. Delete poll
logic. Change while(1) loop to while(0).
(sim_engine_run): New function.
* Makefile.in (SIM_OBJS): Add sim-resume.o.
