2016-03-30Don't override definition a shared object by one in a later shared object.Cary Coutant2-0/+13
In PR 16979, a reference to malloc is being resolved to an unversioned reference in libmalloc.so. When linked with --as-needed, however, the dynamic table does not list libmalloc.so as a DT_NEEDED library. If we have a reference to an unversioned symbol in a shared object, and we later see a versioned definition in another shared object, we were overriding the first definition with the second in the process of defining the default version. As a result, we no longer think that the first shared object was actually needed to resolve any symbols, and we don't list it as a DT_NEEDED library. This patch fixes the problem by treating the two definitions as separate symbols, so the second definition does not override the first. 2016-03-30 Cary Coutant <ccoutant@gmail.com> gold/ PR gold/16979 * symtab.cc (Symbol_table::define_default_version): Check for case where symbols are both in different shared objects.

2016-03-21Fix problem where gold fails to issue an undefined symbol error during LTO.Cary Coutant7-2/+143
During LTO, if (1) an IR file contains a COMDAT group that is kept, (2) a later non-claimed file contains the same group, which we discard, and (3) the plugin fails to provide a definition of the symbols in that COMDAT group, gold silently resolves any references to those symbols to 0. This patch adds a check for a placeholder symbol when deciding whether to issue an undefined symbol error. It also adds an extra note after any undefined placeholder symbol error that explains that a definition was expected from the plugin. gold/ PR gold/19842 * errors.cc (Errors::undefined_symbol): Add info message when symbol should have been provided by a plugin. * target-reloc.h (issue_undefined_symbol_error): Check for placeholder symbols defined in discarded sections. * testsuite/Makefile.am (plugin_test_9b): New test case. * testsuite/Makefile.in: Regenerate. * testsuite/plugin_test_9b_elf.cc: New test source file. * testsuite/plugin_test_9b_ir.cc: New test source file.

2016-03-20Fix problem where gold cannot build .eh_frame_hdr from ld -r output.Cary Coutant7-12/+145
When running ld -r on objects that have comdat groups, when gold deduplicates a function in a comdat group, it removes the relocations from the EH information that referred to the dropped copy of the function. When running a final link using the result of the -r link, the missing relocation cause it to fail to recognize the FDE for the dropped function. This patch improves gold's FDE scanning to take into account the possibility that an FDE corresponds to a dropped function, and drops that FDE as well. Gnu ld, on the other hand, leaves the relocations in the ld -r output, but makes them R_NONE with an r_sym field of 0. This was sufficient to let both linkers recognize the FDE properly. With this fix, if you do an ld -r with gold, then do the final link with Gnu ld, the .eh_frame_hdr section will not be generated. To make it work with Gnu ld, we would have to leave the R_NONE relocations in, but I think it's better to drop the relocations entirely. I'd hope that if you're doing a -r link with gold, you'll also do the final link with gold. gold/ PR gold/19002 * ehframe.cc (Eh_frame::read_fde): Check for dropped functions. * testsuite/Makefile.am (eh_test_2): New test. * testsuite/Makefile.in: Regenerate. * testsuite/eh_test_2.sh: New test script. * testsuite/eh_test_a.cc (bar): Make it comdat. * testsuite/eh_test_b.cc (bar): Add a duplicate copy.

This patch is a simple refactoring that will allow the MIPS backend to replace the Output_data_reloc_base::do_write() method without copying its entire implementation. I've moved the implementation of do_write() into a function template, which can be instantiated with a custom class to write the MIPS-specific relocation format. The custom class for MIPS needs access to the symbol index and address from Output_reloc, so I've included the part of Vlad's MIPS-64 patch that makes those accessor methods public. 2016-03-08 Cary Coutant <ccoutant@gmail.com> Vladimir Radosavljevic <vladimir.radosavljevic@imgtec.com> gold/ * output.cc (Output_reloc_writer): New type.
