From 1074bc6d41f480e9e7b8f2e68f778225da2559b7 Mon Sep 17 00:00:00 2001 From: Cary Coutant Date: Sat, 14 Jul 2018 11:52:27 -0700 Subject: [PATCH] Fix internal error when using --emit-relocs with plugins. When an .eh_frame section has deferred layout because of plugins, gold was neglecting to mark the section as deferred. When we later processed the corresponding relocation section, we were then ignoring it, causing the internal error later on in the link. gold/ PR gold/23397 * object.cc (Sized_relobj_file::do_layout): Mark section as deferred. * testsuite/Makefile.am (plugin_test_1): Add --emit-relocs option to existing test case. * testsuite/Makefile.in: Regenerate. --- gold/ChangeLog | 8 ++++++++ gold/object.cc | 10 +++++++--- gold/testsuite/Makefile.am | 2 +- gold/testsuite/Makefile.in | 2 +- 4 files changed, 17 insertions(+), 5 deletions(-) diff --git a/gold/ChangeLog b/gold/ChangeLog index 0e50f05..ae0b8c9 100644 --- a/gold/ChangeLog +++ b/gold/ChangeLog @@ -1,5 +1,13 @@ 2018-07-14 Cary Coutant + PR gold/23397 + * object.cc (Sized_relobj_file::do_layout): Mark section as deferred. + * testsuite/Makefile.am (plugin_test_1): Add --emit-relocs option to + existing test case. + * testsuite/Makefile.in: Regenerate. + +2018-07-14 Cary Coutant + PR gold/23409 * symtab.cc (Symbol_table::define_special_symbol): Add check for version name on existing symbol. diff --git a/gold/object.cc b/gold/object.cc index 374340f..084212c 100644 --- a/gold/object.cc +++ b/gold/object.cc @@ -1742,9 +1742,13 @@ Sized_relobj_file::do_layout(Symbol_table* symtab, out_section_offsets[i] = invalid_address; } else if (this->is_deferred_layout()) - this->deferred_layout_.push_back( - Deferred_layout(i, name, sh_type, pshdrs, - reloc_shndx[i], reloc_type[i])); + { + out_sections[i] = reinterpret_cast(2); + out_section_offsets[i] = invalid_address; + this->deferred_layout_.push_back( + Deferred_layout(i, name, sh_type, pshdrs, + reloc_shndx[i], reloc_type[i])); + } else eh_frame_sections.push_back(i); continue; diff --git a/gold/testsuite/Makefile.am b/gold/testsuite/Makefile.am index e15788e..c1c5539 100644 --- a/gold/testsuite/Makefile.am +++ b/gold/testsuite/Makefile.am @@ -2256,7 +2256,7 @@ check_SCRIPTS += plugin_test_1.sh check_DATA += plugin_test_1.err MOSTLYCLEANFILES += plugin_test_1.err plugin_test_1: two_file_test_main.o two_file_test_1.o.syms two_file_test_1b.o.syms two_file_test_2.o.syms empty.o.syms gcctestdir/ld plugin_test.so - $(CXXLINK) -Bgcctestdir/ -Wl,--no-demangle,--plugin,"./plugin_test.so",--plugin-opt,"_Z4f13iv" two_file_test_main.o two_file_test_1.o.syms two_file_test_1b.o.syms two_file_test_2.o.syms empty.o.syms 2>plugin_test_1.err + $(CXXLINK) -Bgcctestdir/ -Wl,--no-demangle,--emit-relocs,--plugin,"./plugin_test.so",--plugin-opt,"_Z4f13iv" two_file_test_main.o two_file_test_1.o.syms two_file_test_1b.o.syms two_file_test_2.o.syms empty.o.syms 2>plugin_test_1.err plugin_test_1.err: plugin_test_1 @touch plugin_test_1.err diff --git a/gold/testsuite/Makefile.in b/gold/testsuite/Makefile.in index 7305d32..08b5c07 100644 --- a/gold/testsuite/Makefile.in +++ b/gold/testsuite/Makefile.in @@ -8922,7 +8922,7 @@ uninstall-am: @GCC_TRUE@@NATIVE_LINKER_TRUE@ test -d alt || mkdir -p alt @GCC_TRUE@@NATIVE_LINKER_TRUE@ $(CXXCOMPILE) -c -o $@ $< @GCC_TRUE@@NATIVE_LINKER_TRUE@@PLUGINS_TRUE@plugin_test_1: two_file_test_main.o two_file_test_1.o.syms two_file_test_1b.o.syms two_file_test_2.o.syms empty.o.syms gcctestdir/ld plugin_test.so -@GCC_TRUE@@NATIVE_LINKER_TRUE@@PLUGINS_TRUE@ $(CXXLINK) -Bgcctestdir/ -Wl,--no-demangle,--plugin,"./plugin_test.so",--plugin-opt,"_Z4f13iv" two_file_test_main.o two_file_test_1.o.syms two_file_test_1b.o.syms two_file_test_2.o.syms empty.o.syms 2>plugin_test_1.err +@GCC_TRUE@@NATIVE_LINKER_TRUE@@PLUGINS_TRUE@ $(CXXLINK) -Bgcctestdir/ -Wl,--no-demangle,--emit-relocs,--plugin,"./plugin_test.so",--plugin-opt,"_Z4f13iv" two_file_test_main.o two_file_test_1.o.syms two_file_test_1b.o.syms two_file_test_2.o.syms empty.o.syms 2>plugin_test_1.err @GCC_TRUE@@NATIVE_LINKER_TRUE@@PLUGINS_TRUE@plugin_test_1.err: plugin_test_1 @GCC_TRUE@@NATIVE_LINKER_TRUE@@PLUGINS_TRUE@ @touch plugin_test_1.err @GCC_TRUE@@NATIVE_LINKER_TRUE@@PLUGINS_TRUE@plugin_test_2: two_file_test_main.o two_file_test_1.o.syms two_file_test_1b.o.syms two_file_shared_2.so gcctestdir/ld plugin_test.so -- 2.7.4
