813 * gencode.c: For sbc8, check the carry and increment the source
814 before trying to set the carry for the result.

AC		 818 * interp.c (sim_get_info): Don't crash if the command line is 0.
819 Define prototype for sim_get_info() and init_system().
820 (sim_info): Correct call to sim_get_info().

824 * configure.in: Recognize m6811-*-*.
825 * configure: Regenerate.
826 * m68hc11_sim.h (cpu_ccr_update_add8, cpu_ccr_update_add16,
827 cpu_ccr_update_sub8, cpu_ccr_update_sub16):
828 Correct the computation of carry of 8 and 16-bits add and subtract.
829 * gencode.c: Use cpu_ccr_update_sub8 for subtraction (carry and
830 overflow set in a different manner than add).

833
834 * dv-m68hc11.c (dv_m6811_attach_address_callback): Removed a
835 trace message.
836 * interp.c (sim_open, sim_create_inferior): Initialize the
837 cpu_elf_start from the ELF header.
838 * m68hc11_sim.c (cpu_initialize): Clear the new data members.
839 (cpu_restart): Use cpu_elf_start as the starting address when
840 the flag is set.
841 (cpu_special): When cpu_use_elf_start is set, the WAI instruction
842 exits the simulator (exit status is in D).
843 * m68hc11_sim.h (_sim_cpu): Added members cpu_use_elf_start and
844 cpu_elf_star to start execution at address specified in ELF file.

847
848 * Makefile.in, config.in, configure, configure.in: New files.
849 * gencode.c: New file, generation of 68HC11 interpreter.
850 * m68hc11_sim.h, m68hc11_sim.c: New files, specific operations
851 for interpreter.
852 * interrupts.c, interrupts.h: New files, management of interrupts.
72f4393d 853 * interp.c, sim-main.h,

855 dv-m68hc11tim.c, dv-pram.c: New files representing devices for
856 68HC11 (dv-pram.c is generic and could probably migrate to common).
857 * emulos.c: New file, basic emulation of some os.
