 683         * gencode.c: Fixed sbc8 and adc8 when there was a initial carry.
 684

 686
 687         * sim-main.h (SIM_HANDLES_LMA): Define to enable loading using lma.

 690
 691         * dv-m68hc11.c (attach_m68hc11_regs): Save the size of the
 692         register region in the m68hc11cpu struct.
 693         (m68hc11cpu_io_write): When the IO mapping addres changes,
 694         detach the register region and re-attach it at the new address.
 695         (m68hc11cpu_io_read_buffer): Renamed base_address into
 696         attach_address.
 697         (m68hc11cpu_io_write_buffer): Likewise. Pass the hw pointer
 698         to m68hc11cpu_io_write.
 699
 700 1999-08-13  Stephane Carrez  <stcarrez@worldnet.fr>
 701
 702         * gencode.c: For sbc8, check the carry and increment the source
 703         before trying to set the carry for the result.
 704
 705 1999-05-24  John S. Kallal <kallal@voicenet.com>
 706
 707         * interp.c (sim_get_info): Don't crash if the command line is 0.
 708         Define prototype for sim_get_info() and init_system().
 709         (sim_info): Correct call to sim_get_info().
 710
 711 1999-05-16  Stephane Carrez  <stcarrez@worldnet.fr>
 712
 713         * configure.in: Recognize m6811-*-*.
 714         * configure: Regenerate.
 715         * m68hc11_sim.h (cpu_ccr_update_add8, cpu_ccr_update_add16,
 716         cpu_ccr_update_sub8, cpu_ccr_update_sub16):
 717         Correct the computation of carry of 8 and 16-bits add and subtract.
 718         * gencode.c: Use cpu_ccr_update_sub8 for subtraction (carry and
 719         overflow set in a different manner than add).
 720
 721 1999-05-14  Stephane Carrez  <stcarrez@worldnet.fr>
 722
 723         * dv-m68hc11.c (dv_m6811_attach_address_callback): Removed a
 724         trace message.
 725         * interp.c (sim_open, sim_create_inferior): Initialize the
 726         cpu_elf_start from the ELF header.
 727         * m68hc11_sim.c (cpu_initialize): Clear the new data members.
 728         (cpu_restart): Use cpu_elf_start as the starting address when
 729         the flag is set.
 730         (cpu_special): When cpu_use_elf_start is set, the WAI instruction
 731         exits the simulator (exit status is in D).
 732         * m68hc11_sim.h (_sim_cpu): Added members cpu_use_elf_start and
 733         cpu_elf_star to start execution at address specified in ELF file.
 734
 735 1999-05-02  Stephane Carrez  <stcarrez@worldnet.fr>
 736
 737         * Makefile.in, config.in, configure, configure.in: New files.
 738         * gencode.c: New file, generation of 68HC11 interpreter.
 739         * m68hc11_sim.h, m68hc11_sim.c: New files, specific operations
 740         for interpreter.
 741         * interrupts.c, interrupts.h: New files, management of interrupts.
 742         * interp.c, sim-main.h,
 743         * dv-m68hc11.c, dv-m68hc11eepr.c, dv-m68hc11sio.c,
 744         dv-m68hc11tim.c, dv-pram.c: New files representing devices for
 745         68HC11 (dv-pram.c is generic and could probably migrate to common).
 746         * emulos.c: New file, basic emulation of some os.
