2016-06-24fix undefined reference to bfd_link_plugin_object_p during linkJoel Brobecker1-2/+2
When configured with the default options, GDB currently fails to link, due to an undefined reference to bfd_link_plugin_object_p, coming from elflink.c: #ifdef BFD_SUPPORTS_PLUGINS || (abfd->plugin_format == bfd_plugin_unknown && bfd_link_plugin_object_p (abfd)) #endif This is because BFD_SUPPORTS_PLUGINS is always defined. It is its value that determines whether plugin support is enabled or not. bfd/ChangeLog: * elflink.c: Check the value of BFD_SUPPORTS_PLUGINS rather than its existance.
2016-06-24MIPS objcopy --rename-section fixAlan Modra2-6/+7
Some MIPS targets use a named section symbol rather than a symbol with no name as is used with most ELF targets. When renaming sections, the named section symbol needs to be renamed too. Rather than fix this bug, I'd originally intended to just correct the xfail added recently for update-1.o vs update4.o in update-section.exp, using the same set of targets for the localize-hidden-1 mips xfail. I'd extracted that target test into a new function, is_bad_symtab. It turns out to be useful in readelf.exp too. bfd/ * config.bfd: Delete mips vxworks patterns matched earlier. Combine mips*-*-none with mips*-*-elf*. binutils/ * objcopy.c (find_section_rename): Forward declare. Remove ibfd and sec_ptr param. Add old_name param. Allow for NULL returned_flags. Move read of section name and flags to.. (setup_section): ..here. Update find_section_rename call. (filter_symbols): Rename section symbols for renamed sections. (copy_object): Call filter_symbols when renamed sections. * testsuite/lib/binutils-common.exp (is_bad_symtab): New. * testsuite/binutils-all/update-section.exp: Revert 96037eb0 mips xfail. * testsuite/binutils-all/objcopy.exp (copy_executable): Use is_bad_symtab.

2016-06-21MIPS/BFD: Don't stop processing on a cross-mode jump conversion errorMaciej W. Rozycki2-7/+13
As with commit ed53407eec9e ("MIPS/BFD: Don't stop processing on `bfd_reloc_outofrange'") don't bail out right away and instead continue processing on a cross-mode jump conversion error, so that any further issues are also reported. Adjust message formatting accordingly, using `%X' to abort processing at conclusion. Remove the full stop from the end of the message, for consistency across error reporting. Adjust the corresponding test case accordingly and make it trigger the error twice. bfd/ * elfxx-mips.c (mips_elf_perform_relocation): Call `info->callbacks->einfo' rather than `*_bfd_error_handler' and use the `%X%H' format for the cross-mode jump conversion error message.

Continue processing rather than returning failure. ld/ * testsuite/ld-mips-elf/mode-change-error-1a.s: Trigger an error twice rather than once. * testsuite/ld-mips-elf/mode-change-error-1.d: Adjust accordingly.

2016-06-18Don't generate PLT for IFUNC GOT/pointer referenceH.J. Lu6-227/+534
If a backend supports it, PLT entry isn't needed when all references to a STT_GNU_IFUNC symbols are done via GOT or static function pointers. For GOT entries, We generate dynamic R_*_GLOB_DAT relocations for preemptable symbols and R_*_IRELATIVE relocations for non-preemptable symbols to update them with real function address. For static pointer pointers, we generate dynamic pointer relocations and store them in: 1. .rel[a].ifunc section in PIC object. 2. .rel[a].got section in dynamic executable. 3. .rel[a].iplt section in static executable.

numbers. This patch adds support for the opcode architectures SPARC_OPCODE_ARCH_V9{C,D,E,V,M} and its associated BFD machine numbers bfd_mach_sparc_v9{c,d,e,v,m} and bfd_mach_sparc_v8plus{c,d,e,v,m}. Note that for arches up to v9b (UltraSPARC III), the detection of the BFD machine type was based on the bits in the e_machine field of the ELF header. However, there are no more available bits in that field, so this patch takes the approach of using the hardware capabilities stored in the object attributes HWCAPS/HWCAPS2 in order to characterize the machine the object was built for. bfd/ChangeLog: 2016-06-17 Jose E.

commit bf52d7c72035679e6b3ab601133c56a4388f4dc9 Author: H.J. Lu <hjl.tools@gmail.com> Date: Wed Jun 15 10:35:38 2016 -0700 Don't check undefined symbol for IFUNC reloc
2016-06-16Don't check undefined symbol for IFUNC relocH.J. Lu2-14/+8
Since x86 elf_*_check_relocs is called after all symbols have been resolved, there is no need to check undefined symbols for relocations against IFUNC symbols. bfd/ * elf32-i386.c (elf_i386_check_relocs): Don't check undefined symbols for relocations against IFUNC symbols. * elf64-x86-64.c (elf_x86_64_check_relocs): Likewise. ld/ * testsuite/ld-i386/i386.exp: Run pr19636-2e-nacl. * testsuite/ld-i386/pr19636-2e.d: Skip for NaCl targets.

2016-06-16bfd/s390: Fix DT_PLTRELSZ in presence of R_390_IRELATIVE.Marcin Kościelnicki3-6/+10
This was broken by 4ade44b727ee77adaa9c22719935d012e253a5e6, which changed the calculation to use the .rela.plt linker section instead of its output section - thus skipping .rela.iplt . Fix the calculations to include it. bfd/ChangeLog: * elf32-s390.c (elf_s390_finish_dynamic_sections): Include .rela.iplt in DT_PLTRELSZ. * elf64-s390.c (elf_s390_finish_dynamic_sections): Likewise, for DT_PLTRELSZ and DT_RELASZ as well.
2016-06-16Skip relocations in non-loaded, non-alloced sectionsH.J. Lu3-28/+49
Don't do anything special with non-loaded, non-alloced sections. In particular, any relocs in such sections should not affect GOT and PLT reference counting (ie. we don't allow them to create GOT or PLT entries), there's no possibility or desire to optimize TLS relocs, and there's not much point in propagating relocs to shared libs that the dynamic linker won't relocate. * elf32-i386.c (elf_i386_check_relocs): Skip relocations in non-loaded, non-alloced sections. * elf64-x86-64.c (elf_x86_64_check_relocs): Likewise.

2016-06-14Check R_*_IRELATIVE in x86 reloc_type_classH.J. Lu3-11/+23
elf_{i386|x86_64}_reloc_type_class should return reloc_class_ifunc for R_386_IRELATIVE/R_X86_64_IRELATIVE relocations. There is no need to check symbol type for STN_UNDEF symbol index. * elf32-i386.c (elf_i386_reloc_type_class): Check R_386_IRELATIVE. Don't check symbol type for STN_UNDEF symbol index. * elf64-x86-64.c (elf_x86_64_reloc_type_class): Check R_X86_64_IRELATIVE. Don't check symbol type for STN_UNDEF symbol index.

2016-06-14Set my_archive for thin archivesAlan Modra9-11/+35
LTO plugin support in plugin_maybe_claim wants to close the IR bfd after replacing it with the recompiled object, but can't do so for archive elements due to various pointers that access the archive bfd.
