2014-02-05Fix problems with the --dynamic-list option.Cary Coutant1-0/+7
PR gold/13577 complains that even though symbols listed in the --dynamic-list script are exported, they are still bound symbolically if -Bsymbolic is also used. There are two underlying problems here. First, -Bsymbolic should be overridden by --dynamic-list, since the dynamic list provides an explicit list of symbols that are not bound within the library, and if we go ahead and set DT_SYMBOLIC, then the dynamic loader will bind it within the library anyway. Second, gold did not properly identify the symbols listed in the file as preemptible. PR gold/16530 complains that symbols listed in the --dynamic-list script can still be garbage collected. I've fixed this by checking the symbols as they're added to the symbol table. (Unlike the --export-dynamic-symbol option, we can't iterate over the list, because the --dynamic-list script can have wildcards in it.) gold/ 2014-02-05 Cary Coutant <ccoutant@google.com> PR gold/13577 * options.cc (General_options::parse_dynamic_list): Set have_dynamic_list_.

2013-01-18gold: enable new dtags by defaultMike Frysinger1-1/+1
The "new" dtags options have been around for 14+ years, and for all the targets that gold supports, these flags have always existed. So enable them by default. Having behavior be different from ld.bfd isn't new, and this behavior is the "better" one, so there shouldn't be a problem based on that. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
