From a84f8df0e2027400910e339824444dc45ba6e4f4 Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Tue, 9 Jun 2015 23:44:13 +0800 Subject: sim: m68hc11: switch to common sim_resume This code already matched the common sim reusme logic, so we can simply drop it and pull in the common code. --- sim/m68hc11/interp.c | 76 ---------------------------------------------------- 1 file changed, 76 deletions(-) (limited to 'sim/m68hc11/interp.c') diff --git a/sim/m68hc11/interp.c b/sim/m68hc11/interp.c index e9f3aab..14a8231 100644 --- a/sim/m68hc11/interp.c +++ b/sim/m68hc11/interp.c @@ -699,79 +699,3 @@ sim_store_register (SIM_DESC sd, int rn, unsigned char *memory, int length) return 2; } - -/* Halt the simulator after just one instruction */ - -static void -has_stepped (SIM_DESC sd, - void *data) -{ - ASSERT (STATE_MAGIC (sd) == SIM_MAGIC_NUMBER); - sim_engine_halt (sd, NULL, NULL, NULL_CIA, sim_stopped, SIM_SIGTRAP); -} - - -/* Generic resume - assumes the existance of sim_engine_run */ - -void -sim_resume (SIM_DESC sd, - int step, - int siggnal) -{ - sim_engine *engine = STATE_ENGINE (sd); - jmp_buf buf; - int jmpval; - - ASSERT (STATE_MAGIC (sd) == SIM_MAGIC_NUMBER); - - /* we only want to be single stepping the simulator once */ - if (engine->stepper != NULL) - { - sim_events_deschedule (sd, engine->stepper); - engine->stepper = NULL; - } - sim_module_resume (sd); - - /* run/resume the simulator */ - engine->jmpbuf = &buf; - jmpval = setjmp (buf); - if (jmpval == sim_engine_start_jmpval - || jmpval == sim_engine_restart_jmpval) - { - int last_cpu_nr = sim_engine_last_cpu_nr (sd); - int next_cpu_nr = sim_engine_next_cpu_nr (sd); - int nr_cpus = sim_engine_nr_cpus (sd); - - sim_events_preprocess (sd, last_cpu_nr >= nr_cpus, next_cpu_nr >= nr_cpus); - if (next_cpu_nr >= nr_cpus) - next_cpu_nr = 0; - - /* Only deliver the siggnal ]sic] the first time through - don't - re-deliver any siggnal during a restart. */ - if (jmpval == sim_engine_restart_jmpval) - siggnal = 0; - - /* Install the stepping event after having processed some - pending events.
