2015-04-28Tidy PowerPC gold find_global_entry usesAlan Modra2-17/+35
Completely removing the assert probably wasn't the best idea, so reinstate it for allocated sections. Also cope with debug info potentially referring to a missing plt call stub. And a tidy. find_global_entry now returns an Address, so make temps holding the return value of type Address, and compare against invalid_address. * powerpc.cc (Target_powerpc::do_dynsym_value): Use Address rather than unsigned int for find_global_entry result temp.

2015-04-28PowerPC gold assertion on missing global entry stubAlan Modra2-14/+23
Global entry stubs are used on ELFv2 to provide addresses for functions not defined in a non-PIC executable but whose address is taken, in much the same way as PLT stub code is used on other targets to provide function addresses. We don't want to insert a global entry stub just because (bogus) debug info refers to the address of a non-local function, but we also don't want gold to die. * powerpc.cc (Target_powerpc::Relocate::relocate): Don't assert on missing global entry stub due to bogus debug info.

2015-04-23Add option --weak-unresolved-symbols to treat unresolved symbols as weak ref.Sriraman Tallam6-5/+69
This patch adds option --weak-unresolved-symbols to treat unresolved symbols as weak references. This is helpful when we want the link to succeed with unresolved symbols and the dynamic loader to not complain at run-time. Option --warn-unresolved-symbols lets the link succeed but could fail at run-time with unresolved symbol warnings especially when the unresolved symbols have GOT entries and dynamic relocations against them, like when -fPIE is used.

2015-03-22Fix support for i386 TLS GD-to-IE optimization.Cary Coutant2-19/+14

2015-03-21Fix internal error with -z relro when .tbss is last relro section.Cary Coutant2-3/+10
When calculating the padding necessary to align the end of the relro segment to a page boundary, gold erroneously ignores the .tdata section when checking to see if there are any relro sections (so if .tdata is the only relro section, we fail to align the segment properly), and erroneously pads the cumulative size of the segment based on the alignment of .tbss. If there are no relro sections following .tbss, it then fails to note the padding needed at the end of .tdata. This patch fixes both problems. is_first_section_relro() will return true when it sees a .tdata section, and we do not align the cumulative size until after checking for the .tbss section. gold/ PR gold/14217 * output.cc (Output_segment::is_first_section_relro): Don't ignore .tdata section.

2015-03-21Fix internal error in do_relocate_sections when using plugins.Cary Coutant2-3/+9
In a previous patch for PR 14675, to fix a problem with the .eh_frame section when static linking, I added a step to finalize the .eh_frame section at the end of the first link pass. This patch caused PR 18152, where a plugin-claimed object caused a non-claimed object's layout to be deferred until replacement files were read. The call to finalize_eh_frame_section() is happening before the layout of the deferred objects, leading to the internal error in do_relocate_sections. This patch moves the finalization of the .eh_frame section to after deferred objects have been processed. gold/ PR gold/14675 PR gold/18152 * gold.cc (queue_middle_tasks): Finalize .eh_frame after laying out deferred objects.

Because the __EH_FRAME_BEGIN__ symbol is provided in an empty .eh_frame section in crtbeginT.o, if crt1.o has a non-empty .eh_frame section, we place all optimized .eh_frame sections into the output section ahead of the __EH_FRAME_BEGIN__ symbol, which breaks EH for statically-linked binaries.

2015-02-17[gold] Recognize DWARF5/GCC5 DW_LANG_Fortran03 and DW_LANG_Fortran08.Mark Wielaard2-1/+8
DWARFv5 defines and GCC5 may output two new DW_LANG constants for the Fortran 2003 and Fortran 2008 standards. Recognize both in gold gdb-index as unsupported. For consistency also add the other new DWARF5/GCC5 language constants in the elfcpp::DW_LANG enum to match include/dwarf2.h. elfcpp/ChangeLog: * dwarf.h (enum DW_LANG): Add DW_LANG_C_plus_plus_11, DW_LANG_C11, DW_LANG_C_plus_plus_14, DW_LANG_Fortran03 and DW_LANG_Fortran08 from ../include/dwarf2.h. gold/ChangeLog: * gdb-index.cc (Gdb_index_info_reader::visit_top_die): Recognize DW_LANG_Fortran03 and DW_LANG_Fortran08.
2015-02-16Fix --dynamic-list so that symbols not in the list are still exported.Cary Coutant6-14/+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.
