* config.bfd: Add sh-symbian-elf target.
|
||||
* configure.in: Add bfd_elf32_shl_symbian_vec.
|
||||
* configure: Regenerate.
|
||||
* elf-bfd.h (struct elf_backend_data): Add new field
|
||||
'check_directives'.
|
||||
* elflink.c (elf_link_add_object_symbols): Invoke the
|
||||
check_directives function, if defined.
|
||||
* elfxx-target.h: Provide a default, NULL definition for
|
||||
check_directives.
|
||||
* targets.c: Add bfd_elf32_shl_symbian_vec.
|
||||
* elf32-sh.c (sh_elf_swap_insns): Protect against unnecessary
|
||||
definition.
|
||||
(elf32_shlin_grok_prstatus, elf32_shlib_grok_psinfo,
|
||||
* sh_elf_get_flags_from_mach, sh_elf_find_flags): Likewise.
|
||||
(TARGET_BIG_SYM, TARGET_LITTLE_SYM): Only define if they have
|
||||
not already been defined.
|
||||
* elf32-sh64.c: Use SH_TARGET_ALREADY_DEFINED.
|
||||
* sh-symbian.c: New file. Provide functions to support the
|
||||
* sh-symbian-elf target.
|
||||
* Makefile.am: Add elf32-sh-symbian.c
|
||||
* Makefile.in: Regenerate.
