1067         * configure.in: Recognize m6811-*-*.
1068         * configure: Regenerate.
1069         * m68hc11_sim.h (cpu_ccr_update_add8, cpu_ccr_update_add16,
1070         cpu_ccr_update_sub8, cpu_ccr_update_sub16):
1071         Correct the computation of carry of 8 and 16-bits add and subtract.
1072         * gencode.c: Use cpu_ccr_update_sub8 for subtraction (carry and
1073         overflow set in a different manner than add).

1076
1077         * dv-m68hc11.c (dv_m6811_attach_address_callback): Removed a
1078         trace message.
1079         * interp.c (sim_open, sim_create_inferior): Initialize the
1080         cpu_elf_start from the ELF header.
1081         * m68hc11_sim.c (cpu_initialize): Clear the new data members.
1082         (cpu_restart): Use cpu_elf_start as the starting address when
1083         the flag is set.
1084         (cpu_special): When cpu_use_elf_start is set, the WAI instruction
1085         exits the simulator (exit status is in D).
1086         * m68hc11_sim.h (_sim_cpu): Added members cpu_use_elf_start and
1087         cpu_elf_star to start execution at address specified in ELF file.

1090
1091         * Makefile.in, config.in, configure, configure.in: New files.
1092         * gencode.c: New file, generation of 68HC11 interpreter.
1093         * m68hc11_sim.h, m68hc11_sim.c: New files, specific operations
1094         for interpreter.
1095         * interrupts.c, interrupts.h: New files, management of interrupts.
1096         * interp.c, sim-main.h,
1097         * dv-m68hc11.c, dv-m68hc11eepr.c, dv-m68hc11sio.c,
1098         dv-m68hc11tim.c, dv-pram.c: New files representing devices for
1099         68HC11 (dv-pram.c is generic and could probably migrate to common).
1100         * emulos.c: New file, basic emulation of some os.
