1061         * m68hc11_sim.c (cpu_initialize): Clear the new data members.
1062         (cpu_restart): Use cpu_elf_start as the starting address when
1063         the flag is set.
1064         (cpu_special): When cpu_use_elf_start is set, the WAI instruction
1065         exits the simulator (exit status is in D).
1066         * m68hc11_sim.h (_sim_cpu): Added members cpu_use_elf_start and
1067         cpu_elf_star to start execution at address specified in ELF file.

1072         * gencode.c: New file, generation of 68HC11 interpreter.
1073         * m68hc11_sim.h, m68hc11_sim.c: New files, specific operations
1074         for interpreter.
1075         * interrupts.c, interrupts.h: New files, management of interrupts.

1078         dv-m68hc11tim.c, dv-pram.c: New files representing devices for
1079         68HC11 (dv-pram.c is generic and could probably migrate to common).
