(engine_resume): Reorganize. Allow synchronous exit from main loop.
(engine_resume_full): Keep accurate core profile data.
* cgen-utils.c (sim_disassemble_insn): Don't use
sim_core_read_aligned_N, it messes up profiling results.
(sim-{module,options,trace,profile,utils}.o): Clean up dependencies.
(sim-model.o): Add new rule.
(cgen-{scache,trace,utils}.o): Add new rules.
* aclocal.m4 (SIM_AC_OPTION_{SCACHE,DEFAULT_MODEL}): Add.

* cgen-trace.c (trace_insn_fini): Indent output by 2 spaces.
Use trace_printf, not fprintf.
(trace_extract): Use trace_printf, not cgen_trace_printf.
* genmloop.sh (!FAST case): Increment `insn_count'.
* sim-base.h (sim_state_base): Only include scache_size if WITH_SCACHE.
(sim_cpu_base): Rename member `sd' to `state' to be consistent with
access macro's name.
* sim-core.c (sim_core_init): Use EXTERN_SIM_CORE to define it.
Change return type to SIM_RC.
(sim_core_{install,uninstall}): New functions.
* sim-core.h (sim_core_{install,uninstall}): Declare.
(sim_core_init): Use EXTERN_SIM_CORE to define it.
Change return type to SIM_RC.
