gold, ld: Implement -z start-stop-visibility=... option.
gold/
Implement -z start-stop-visibility=... option.
* options.h (class General_options): Handle -z start-stop-visibility=.
(General_options::start_stop_visibility_enum): New public method.
(General_options::set_start_stop_visibility_enum): New private method.
(General_options::start_stop_visibility_enum_): New private member.
* options.cc (General_options::General_options): Add initializer.
(General_options::finalize): Set this->start_stop_visibility_enum_
from string value.
* layout.cc (Layout::define_section_symbols): Use option setting.
bfd/
* elflink.c (bfd_elf_define_start_stop): Use start_stop_visibility
field of bfd_link_info.
include/
* bfdlink.h (struct bfd_link_info): New field start_stop_visibility.
ld/
* NEWS: Mention -z start-stop-visibility=... option for ELF.
* ld.texi (Options): Document -z start-stop-visibility=... option.
* ldmain.c (main): Initialize link_info.start_stop_visibility.
* emultempl/elf.em (gld${EMULATION_NAME}_handle_option):
Parse -z start-stop-visibility=... option.
