 675         * interp.c (sim_get_info): Don't crash if the command line is 0.
 676         Define prototype for sim_get_info() and init_system().
 677         (sim_info): Correct call to sim_get_info().

 680
 681         * configure.in: Recognize m6811-*-*.
 682         * configure: Regenerate.
 683         * m68hc11_sim.h (cpu_ccr_update_add8, cpu_ccr_update_add16,
 684         cpu_ccr_update_sub8, cpu_ccr_update_sub16):
 685         Correct the computation of carry of 8 and 16-bits add and subtract.
 686         * gencode.c: Use cpu_ccr_update_sub8 for subtraction (carry and
 687         overflow set in a different manner than add).

 690
 691         * dv-m68hc11.c (dv_m6811_attach_address_callback): Removed a
 692         trace message.
 693         * interp.c (sim_open, sim_create_inferior): Initialize the
 694         cpu_elf_start from the ELF header.
 695         * m68hc11_sim.c (cpu_initialize): Clear the new data members.
 696         (cpu_restart): Use cpu_elf_start as the starting address when
 697         the flag is set.
 698         (cpu_special): When cpu_use_elf_start is set, the WAI instruction
 699         exits the simulator (exit status is in D).
 700         * m68hc11_sim.h (_sim_cpu): Added members cpu_use_elf_start and
 701         cpu_elf_star to start execution at address specified in ELF file.

 704
 705         * Makefile.in, config.in, configure, configure.in: New files.
 706         * gencode.c: New file, generation of 68HC11 interpreter.
 707         * m68hc11_sim.h, m68hc11_sim.c: New files, specific operations
 708         for interpreter.
 709         * interrupts.c, interrupts.h: New files, management of interrupts.
 710         * interp.c, sim-main.h,
 711         * dv-m68hc11.c, dv-m68hc11eepr.c, dv-m68hc11sio.c,
 712         dv-m68hc11tim.c, dv-pram.c: New files representing devices for
 713         68HC11 (dv-pram.c is generic and could probably migrate to common).
 714         * emulos.c: New file, basic emulation of some os.
