* Fix --dynamic-list so that symbols not in the list are still exported.Cary Coutant2015-02-166-14/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In PR 13577, the complaint was that -Bsymbolic was overriding the binding behavior for symbols listed in the --dynamic-list by setting the DT_SYMBOLIC tag in the dynamic table. In reading the Gnu ld manual, I decided that --dynamic-list should be mutually exclusive of -Bsymbolic, and modified gold so that --dynamic-list would treat symbols listed as preemptible, and all other symbols as internally bound. I was wrong. PR 16992 shows that with --dynamic-list (and not -Bsymbolic), a symbol not listed in the dynamic list is being internally bound within the shared library, but because it's still in the dynamic symbol table, we expose it to a COPY relocation, and things go really bad from there. (I can reproduce the same failure, simply by turning on -Bsymbolic-functions with the Gnu linker. Even though the symbol is bound internally, it's still exported to the dynamic symbol table, and is exposed to a COPY relocation.) I've backed out part of the fix for PR 13577, and -Bsymbolic (or -Bsymbolic-functions) can now be used with --dynamic-list, but if the two are used together, we do not set DT_SYMBOLIC or DF_SYMBOLIC (this matches Gnu ld behavior). We now treat symbols listed in the dynamic list as premptible, but we do not automatically treat symbols not listed there as non-premptible. gold/ PR gold/13577 PR gold/16992 * layout.cc (Layout::finish_dynamic_section): Don't set DT_SYMBOLIC or DF_SYMBOLIC if --dynamic-list option is used. * options.cc (General_options::finalize): --dynamic-list is not mutually exclusive with -Bsymbolic. * symtab.h (Symbol::is_preemptible): Don't exclude dynamic symbols not listed in --dynamic-list. * testsuite/Makefile.am (dynamic_list_lib2.so): Add -Bsymbolic-functions. * testsuite/Makefile.in: Regenerate.

| | | | | | | | | | | It's possible for the section grouping code to decide that the last section looked at (the first section by address) doesn't fit into a group. In one case that section is already a group owner and that is handled correctly. In other cases the section should be put into its own group. Like this: * powerpc.cc (Stub_control::set_output_and_owner): New function. (Target_powerpc::group_sections): Use it.
