1069         * dv-m68hc11.c (dv_m6811_attach_address_callback): Removed a
1070         trace message.
1071         * interp.c (sim_open, sim_create_inferior): Initialize the
1072         cpu_elf_start from the ELF header.
1073         * m68hc11_sim.c (cpu_initialize): Clear the new data members.
1074         (cpu_restart): Use cpu_elf_start as the starting address when
1075         the flag is set.
1076         (cpu_special): When cpu_use_elf_start is set, the WAI instruction
1077         exits the simulator (exit status is in D).
1078         * m68hc11_sim.h (_sim_cpu): Added members cpu_use_elf_start and
1079         cpu_elf_star to start execution at address specified in ELF file.

1082
1083         * Makefile.in, config.in, configure, configure.in: New files.
1084         * gencode.c: New file, generation of 68HC11 interpreter.
1085         * m68hc11_sim.h, m68hc11_sim.c: New files, specific operations
1086         for interpreter.
1087         * interrupts.c, interrupts.h: New files, management of interrupts.
1088         * interp.c, sim-main.h,
1089         * dv-m68hc11.c, dv-m68hc11eepr.c, dv-m68hc11sio.c,
1090         dv-m68hc11tim.c, dv-pram.c: New files representing devices for
1091         68HC11 (dv-pram.c is generic and could probably migrate to common).
1092         * emulos.c: New file, basic emulation of some os.
