(cris_start_address, cris_program_offset): New variables.
(OPTION_CRIS_PROGRAM_OFFSET, OPTION_CRIS_STARTADDR): New option
enums.
(cris_options): New options --cris-program-offset and
--cris-start-address.
(cris_option_handler): Handle new options.
(cris_program_offset_write, cris_set_section_offset_iterator)
(cris_offset_sections, cris_offset_sections): New functions.
(sim_load): Use cris_program_offset_write as function argument to
cris_load_elf_file, not sim_write.
(struct offsetinfo): New struct.
(cris_handle_interpreter): Fix typo in comment.
(sim_open): Call cris_offset_sections as soon as the bfd of the
infile is available. Gate bfd validity checks on abfd non-NULL.
(sim_create_inferior): Let cris_start_address when != -1 override
other start-address choices.
* cris/sim-if.c: Include elf-bfd.h.
(struct progbounds): New members end_loadmem, start_nonloadmem.
(xprintf, eprintf): New functions, copied from common/sim-load.c.
(cris_load_elf_file, sim_load, cris_get_progbounds): New functions.
(get_progbounds_iterator): Renamed from get_progbounds. Make
static. Update head comment. Set new struct progbounds members.
(exec_load_addr, interp_load_addr, interp_start_addr): New static
variables.
(aux_ent_phdr, aux_ent_phent, aux_ent_phnum, aux_ent_base)
(aux_ent_entry, cris_write_interp, cris_handle_interpreter): New
functions.
(sim_open): New constant array auxv_entries. Rewrite AUX_ENT
handling to use auxv_entries. Improve error message and checking
for invalid programs. Use new variable abfd for the program
instead of for each access reaching into sd to get it.
(sim_create_inferior): If non-zero, use interp_start_addr instead
of the program start address.
(cris_disassemble_insn): Remove incorrect and unclear, supposedly
stale comment. Always specify little-endian.
(cris_unknown_syscall_action): Declare.
* cris/sim-if.c (cris_unknown_syscall_action): Define.
(cris_options): Add cris-unknown-syscall option.
(cris_option_handler): Correct comment about and error message for
invalid --cris-cycles argument. Handle --cris-unknown-syscall.
* cris/traps.c: Include stdarg.h
(cris_unknown_syscall): New function.
(cris_break_13_handler): Instead of sim_io_eprintf and
sim_engine_halt, call cris_unknown_syscall to handle more or less
unknown syscalls. Adjust code as necessary to handle return
value.
* cris/Makefile.in (CONFIG_DEVICES): Remove redundant setting.
(dv-cris.o, dv-rv.o rvdummy$(EXEEXT), rvdummy.o): New rules.
(all): Depend on rvdummy$(EXEEXT).
* cris/configure.ac: Call SIM_AC_OPTION_WARNINGS. Check for
sys/socket.h and sys/select.h. Call SIM_AC_OPTION_HARDWARE,
default off.
* cris/configure: Regenerate.
* cris/cris-sim.h (cris_have_900000xxif): Declare here.
(enum cris_interrupt_type, crisv10deliver_interrupt)
(crisv32deliver_interrupt: New declarations.
* cris/cris-tmpl.c [WITH_HW] (MY (f_model_insn_after)): Call
sim_events_tickn and set state-events member work_pending when it's
time for the next event.
[WITH_HW] (MY (f_specific_init)): Set CPU-model-specific
interrupt-delivery function.
* cris/crisv10f.c (MY (deliver_interrupt)): New function.
* cris/crisv32f.c (MY (deliver_interrupt)): New function.
* cris/devices.c: Include hw-device.h.
(device_io_read_buffer) [WITH_HW]: Call hw_io_read_buffer.
(device_io_write_buffer): Only perform 0x900000xx-functions if
cris_have_900000xxif is nonzero. Else if WITH_HW defined,
call hw_io_write_buffer. Add return 0 last in function.
* cris/sim-if.c (cris_have_900000xxif): Now global.
(sim_open) [WITH_HW]: Clear deliver_interrupt cpu member.
Force "-model" option, effectively.
* cris/sim-main.h (cris_interrupt_delivery_fn): New type.
(struct _sim_cpu) [WITH_HW]: New member deliver_interrupt.
