804 Correct the computation of carry of 8 and 16-bits add and subtract.
805 * gencode.c: Use cpu_ccr_update_sub8 for subtraction (carry and
806 overflow set in a different manner than add).

810 * dv-m68hc11.c (dv_m6811_attach_address_callback): Removed a
811 trace message.
812 * interp.c (sim_open, sim_create_inferior): Initialize the
813 cpu_elf_start from the ELF header.
814 * m68hc11_sim.c (cpu_initialize): Clear the new data members.
815 (cpu_restart): Use cpu_elf_start as the starting address when
816 the flag is set.
817 (cpu_special): When cpu_use_elf_start is set, the WAI instruction
818 exits the simulator (exit status is in D).
819 * m68hc11_sim.h (_sim_cpu): Added members cpu_use_elf_start and
820 cpu_elf_star to start execution at address specified in ELF file.

824 * Makefile.in, config.in, configure, configure.in: New files.
825 * gencode.c: New file, generation of 68HC11 interpreter.
826 * m68hc11_sim.h, m68hc11_sim.c: New files, specific operations
827 for interpreter.
828 * interrupts.c, interrupts.h: New files, management of interrupts.

AC		 830 * dv-m68hc11.c, dv-m68hc11eepr.c, dv-m68hc11sio.c,
831 dv-m68hc11tim.c, dv-pram.c: New files representing devices for
832 68HC11 (dv-pram.c is generic and could probably migrate to common).
833 * emulos.c: New file, basic emulation of some os.
