 667         cpu_ccr_update_sub8, cpu_ccr_update_sub16):
 668         Correct the computation of carry of 8 and 16-bits add and subtract.
 669         * gencode.c: Use cpu_ccr_update_sub8 for subtraction (carry and
 670         overflow set in a different manner than add).

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

 687
 688         * Makefile.in, config.in, configure, configure.in: New files.
 689         * gencode.c: New file, generation of 68HC11 interpreter.
 690         * m68hc11_sim.h, m68hc11_sim.c: New files, specific operations
 691         for interpreter.
 692         * interrupts.c, interrupts.h: New files, management of interrupts.
 693         * interp.c, sim-main.h,
 694         * dv-m68hc11.c, dv-m68hc11eepr.c, dv-m68hc11sio.c,
 695         dv-m68hc11tim.c, dv-pram.c: New files representing devices for
 696         68HC11 (dv-pram.c is generic and could probably migrate to common).
 697         * emulos.c: New file, basic emulation of some os.
