1011 * dv-m68hc11.c (attach_m68hc11_regs): Save the size of the
1012 register region in the m68hc11cpu struct.
1013 (m68hc11cpu_io_write): When the IO mapping addres changes,
1014 detach the register region and re-attach it at the new address.
1015 (m68hc11cpu_io_read_buffer): Renamed base_address into
1017 (m68hc11cpu_io_write_buffer): Likewise. Pass the hw pointer
1018 to m68hc11cpu_io_write.
1020 1999-08-13 Stephane Carrez <stcarrez@worldnet.fr>
1022 * gencode.c: For sbc8, check the carry and increment the source
1023 before trying to set the carry for the result.
1025 1999-05-24 John S. Kallal <kallal@voicenet.com>
1027 * interp.c (sim_get_info): Don't crash if the command line is 0.
1028 Define prototype for sim_get_info() and init_system().
1029 (sim_info): Correct call to sim_get_info().
1031 1999-05-16 Stephane Carrez <stcarrez@worldnet.fr>
1033 * configure.in: Recognize m6811-*-*.
1034 * configure: Regenerate.
1035 * m68hc11_sim.h (cpu_ccr_update_add8, cpu_ccr_update_add16,
1036 cpu_ccr_update_sub8, cpu_ccr_update_sub16):
1037 Correct the computation of carry of 8 and 16-bits add and subtract.
1038 * gencode.c: Use cpu_ccr_update_sub8 for subtraction (carry and
1039 overflow set in a different manner than add).
1041 1999-05-14 Stephane Carrez <stcarrez@worldnet.fr>
1043 * dv-m68hc11.c (dv_m6811_attach_address_callback): Removed a
1045 * interp.c (sim_open, sim_create_inferior): Initialize the
1046 cpu_elf_start from the ELF header.
1047 * m68hc11_sim.c (cpu_initialize): Clear the new data members.
1048 (cpu_restart): Use cpu_elf_start as the starting address when
1050 (cpu_special): When cpu_use_elf_start is set, the WAI instruction
1051 exits the simulator (exit status is in D).
1052 * m68hc11_sim.h (_sim_cpu): Added members cpu_use_elf_start and
1053 cpu_elf_star to start execution at address specified in ELF file.
1055 1999-05-02 Stephane Carrez <stcarrez@worldnet.fr>
1057 * Makefile.in, config.in, configure, configure.in: New files.
1058 * gencode.c: New file, generation of 68HC11 interpreter.
1059 * m68hc11_sim.h, m68hc11_sim.c: New files, specific operations
1061 * interrupts.c, interrupts.h: New files, management of interrupts.
1062 * interp.c, sim-main.h,
1063 * dv-m68hc11.c, dv-m68hc11eepr.c, dv-m68hc11sio.c,
1064 dv-m68hc11tim.c, dv-pram.c: New files representing devices for
1065 68HC11 (dv-pram.c is generic and could probably migrate to common).
1066 * emulos.c: New file, basic emulation of some os.
