 698         register region in the m68hc11cpu struct.
 699         (m68hc11cpu_io_write): When the IO mapping addres changes,
 700         detach the register region and re-attach it at the new address.
 701         (m68hc11cpu_io_read_buffer): Renamed base_address into
 702         attach_address.
 703         (m68hc11cpu_io_write_buffer): Likewise. Pass the hw pointer
 704         to m68hc11cpu_io_write.
 705
 706 1999-08-13  Stephane Carrez  <stcarrez@worldnet.fr>
 707
 708         * gencode.c: For sbc8, check the carry and increment the source
 709         before trying to set the carry for the result.
 710
 711 1999-05-24  John S. Kallal <kallal@voicenet.com>
 712
 713         * interp.c (sim_get_info): Don't crash if the command line is 0.
 714         Define prototype for sim_get_info() and init_system().
 715         (sim_info): Correct call to sim_get_info().
 716

 718
 719         * configure.in: Recognize m6811-*-*.
 720         * configure: Regenerate.
 721         * m68hc11_sim.h (cpu_ccr_update_add8, cpu_ccr_update_add16,
 722         cpu_ccr_update_sub8, cpu_ccr_update_sub16):
 723         Correct the computation of carry of 8 and 16-bits add and subtract.
 724         * gencode.c: Use cpu_ccr_update_sub8 for subtraction (carry and
 725         overflow set in a different manner than add).
 726
 727 1999-05-14  Stephane Carrez  <stcarrez@worldnet.fr>
 728
 729         * dv-m68hc11.c (dv_m6811_attach_address_callback): Removed a
 730         trace message.
 731         * interp.c (sim_open, sim_create_inferior): Initialize the
 732         cpu_elf_start from the ELF header.
 733         * m68hc11_sim.c (cpu_initialize): Clear the new data members.
 734         (cpu_restart): Use cpu_elf_start as the starting address when
 735         the flag is set.
 736         (cpu_special): When cpu_use_elf_start is set, the WAI instruction
 737         exits the simulator (exit status is in D).
 738         * m68hc11_sim.h (_sim_cpu): Added members cpu_use_elf_start and
 739         cpu_elf_star to start execution at address specified in ELF file.
