Subject: [PATCH] 	* configure: Regenerated.

	* cgen-sim.h (sim_signal_type): Add SIM_SIGINT.
	(cgen_state): New member run_fast_p.
	(cgen_init): Add prototype.
	(sim_disassemble_insn): New arg `cpu'.
	* cgen-trace.c (trace_insn): Update call to sim_disassemble_insn.
	* cgen-utils.c (cgen_init): New function.
	(sim_disassemble_insn): New arg `cpu'.  Rewrite fetching of insn.
	* genmloop.sh: Call engine_halt if loop exits.
