* Fix problem where gold fails to issue an undefined symbol error during LTO.Cary Coutant2016-03-211-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | 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.

* Fix issues with gold undefined symbol diagnostics.Cary Coutant2014-02-051-0/+5
| | | | | | | | | | | | | | | | | | | | | PR binutils/15435 complains that gold issues a visibility error for an weak undefined symbol with hidden visibility. The message should be suppressed if the symbol is a weak undef. An earlier patch to add an extra note about key functions when a class's vtable symbol is undefined missed a case where the reference to the vtable came from a shared library. This patch moves the check to a lower-level routine that catches both cases. gold/ 2014-02-05 Cary Coutant <ccoutant@google.com> * errors.cc (Errors::undefined_symbol): Move undef vtable symbol check to here. * target-reloc.h (is_strong_undefined): New function.
