2016-07-15 Thomas Preud'homme <thomas.preudhomme@arm.com>
bfd/
* elf-bfd.h (elf_backend_filter_implib_symbols): Declare backend hook.
(_bfd_elf_filter_global_symbols): Declare.
* elf.c (_bfd_elf_filter_global_symbols): New function.
* elflink.c (elf_filter_global_symbols): Likewise.
(elf_output_implib): Likewise.
(bfd_elf_final_link): Call above function, failing if it does.
* elfxx-target.h (elf_backend_filter_implib_symbols): Define macro and
default it to NULL.
(elf_backend_copy_indirect_symbol): Fix spacing.
(elf_backend_hide_symbol): Likewise.
(elfNN_bed): Initialize elf_backend_filter_implib_symbols backend hook.
include/
* bfdlink.h (struct bfd_link_info): Declare new ldscript_def and
out_implib_bfd fields.

part and rephrase to apply to ELF targets.

defined in linker scripts.

enumerator.
