 666         * dv-m68hc11.c (dv_m6811_attach_address_callback): Removed a
 667         trace message.
 668         * interp.c (sim_open, sim_create_inferior): Initialize the
 669         cpu_elf_start from the ELF header.
 670         * m68hc11_sim.c (cpu_initialize): Clear the new data members.
 671         (cpu_restart): Use cpu_elf_start as the starting address when
 672         the flag is set.
 673         (cpu_special): When cpu_use_elf_start is set, the WAI instruction
 674         exits the simulator (exit status is in D).
 675         * m68hc11_sim.h (_sim_cpu): Added members cpu_use_elf_start and
 676         cpu_elf_star to start execution at address specified in ELF file.

 680         * Makefile.in, config.in, configure, configure.in: New files.
 681         * gencode.c: New file, generation of 68HC11 interpreter.
 682         * m68hc11_sim.h, m68hc11_sim.c: New files, specific operations
 683         for interpreter.
 684         * interrupts.c, interrupts.h: New files, management of interrupts.
 685         * interp.c, sim-main.h,
 686         * dv-m68hc11.c, dv-m68hc11eepr.c, dv-m68hc11sio.c,
 687         dv-m68hc11tim.c, dv-pram.c: New files representing devices for
 688         68HC11 (dv-pram.c is generic and could probably migrate to common).
 689         * emulos.c: New file, basic emulation of some os.
