@ -1,3 +1,15 @@
2015-04-13 Mike Frysinger <vapier@gentoo.org>
* Makefile.in (MN10300_OBJS): Add sim-cpu.o.
* interp.c (mn10300_pc_get, mn10300_pc_set): New functions.
(sim_open): Declare new local var i. Call sim_cpu_alloc_all.
Call CPU_PC_FETCH & CPU_PC_STORE for all cpus.
(sim_pc_get): Delete.
* sim-main.h (null_cia, NULL_CIA): Delete.
(SIM_CPU): Define.
(struct sim_state): Change cpu to an array of pointers.
(STATE_CPU): Drop & and handle WITH_SMP.
2015-04-06 Mike Frysinger <vapier@gentoo.org>
* Makefile.in (SIM_OBJS): Delete sim-engine.o and sim-hrw.o.
