(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.
|
|
(create_map): Make -1 imply a non-fixed address, not 0. All
callers changed. Only prefer the next higher unmapped address if
the last mapped address is no less than 0x40000000. Check that
the address to be mapped is not already mapped. Update head
comment.
(unmap_pages): Don't call abort when recursive call fails, just
note and return an error if a page in the range couldn't be unmapped.
(cris_bmod_handler, h_supr_set_handler, h_supr_get_handler)
(schedule, make_first_thread, cris_pipe_empty): New local variable sd.
(cris_break_13_handler) <case TARGET_SYS_mmap2>: Handle
non-MAP_FIXED argument overlapping existing map. For MAP_FIXED,
don't abort on page not being mapped. Handle non-anon filemap
with length padded to pagesize.

callers.
(sim_open): Also pass AT_SECURE.

(cris_break_13_handler) <case TARGET_SYS_set_thread_area>: New
case.
|
|
(cris_break_13_handler): Handle it like the exit for the last
thread.
|
|
(TARGET_EPOCH): Update to match TARGET_UTSNAME. Correct comment.
(cris_break_13_handler) <case TARGET_SYS_uname>: Update to
2.6.27. Set machine field to the BFD printable name of the
machine.
|
|
<case TARGET_SYS_mmap2>: Handle TARGET_MAP_DENYWRITE.
|
|
(TARGET_X_OK, TARGET_F_OK): Define.
(cris_break_13_handler) <case TARGET_SYS_access>: New case.

just a short CRIS-specific notice. Tweak the wording for a
failing architecture test.
|
|
(is_mapped_only, cris_dump_map): New functions.
(cris_break_13_handler) <case TARGET_SYS_mmap2>: Handle more flags
and prot combinations and a non-zero page-offset. If
TARGET_MAP_FIXED, unmap pages before mapping them.
<case TARGET_SYS_mprotect>: When checking, allow any length
argument. Don't actually do anything.
<case TARGET_SYS_writev>: New case.
|
|
* 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.
