 682
 683         * dv-m68hc11.c (attach_m68hc11_regs): Save the size of the
 684         register region in the m68hc11cpu struct.
 685         (m68hc11cpu_io_write): When the IO mapping addres changes,
 686         detach the register region and re-attach it at the new address.
 687         (m68hc11cpu_io_read_buffer): Renamed base_address into
 688         attach_address.
 689         (m68hc11cpu_io_write_buffer): Likewise. Pass the hw pointer
 690         to m68hc11cpu_io_write.
 691
 692 1999-08-13  Stephane Carrez  <stcarrez@worldnet.fr>
 693
 694         * gencode.c: For sbc8, check the carry and increment the source
 695         before trying to set the carry for the result.
 696
 697 1999-05-24  John S. Kallal <kallal@voicenet.com>
 698
 699         * interp.c (sim_get_info): Don't crash if the command line is 0.
 700         Define prototype for sim_get_info() and init_system().
 701         (sim_info): Correct call to sim_get_info().
 702
 703 1999-05-16  Stephane Carrez  <stcarrez@worldnet.fr>
 704
 705         * configure.in: Recognize m6811-*-*.
 706         * configure: Regenerate.
 707         * m68hc11_sim.h (cpu_ccr_update_add8, cpu_ccr_update_add16,
 708         cpu_ccr_update_sub8, cpu_ccr_update_sub16):
 709         Correct the computation of carry of 8 and 16-bits add and subtract.
 710         * gencode.c: Use cpu_ccr_update_sub8 for subtraction (carry and
 711         overflow set in a different manner than add).
 712
 713 1999-05-14  Stephane Carrez  <stcarrez@worldnet.fr>
 714
 715         * dv-m68hc11.c (dv_m6811_attach_address_callback): Removed a
 716         trace message.
 717         * interp.c (sim_open, sim_create_inferior): Initialize the
 718         cpu_elf_start from the ELF header.
 719         * m68hc11_sim.c (cpu_initialize): Clear the new data members.
 720         (cpu_restart): Use cpu_elf_start as the starting address when
 721         the flag is set.
 722         (cpu_special): When cpu_use_elf_start is set, the WAI instruction
 723         exits the simulator (exit status is in D).
 724         * m68hc11_sim.h (_sim_cpu): Added members cpu_use_elf_start and
 725         cpu_elf_star to start execution at address specified in ELF file.

 728
 729         * Makefile.in, config.in, configure, configure.in: New files.
 730         * gencode.c: New file, generation of 68HC11 interpreter.
 731         * m68hc11_sim.h, m68hc11_sim.c: New files, specific operations
 732         for interpreter.
 733         * interrupts.c, interrupts.h: New files, management of interrupts.
 734         * interp.c, sim-main.h,
 735         * dv-m68hc11.c, dv-m68hc11eepr.c, dv-m68hc11sio.c,
 736         dv-m68hc11tim.c, dv-pram.c: New files representing devices for
 737         68HC11 (dv-pram.c is generic and could probably migrate to common).
 738         * emulos.c: New file, basic emulation of some os.
