x86_64-rdos is one of the few x86_64 targets that is 64-bit only and the x86_64 configure entries don't depend on elf-vxworks.lo. This results in undefined references from elfxx-x86.o. * configure.ac (elfxx_x86): Define and use. * configure: Regenerate.

2019-04-02RISC-V: Don't check ABI flags if no code section.Jim Wilson2-2/+39
This fixes a glib build failure reported in PR 24389. Using ld -b binary creates an object file with no elf header flags set which has the wrong ABI info for riscv64-linux. But the file also has no code sections, so I added code borrowed from the arm port that only checks the ELF header ABI flags if there is a code section. bfd/ PR 24389 * elfnn-riscv.c (_bfd_riscv_elf_merge_private_bfd_data): Move read of ELF header flags to after check for ELF object file. Loop through sections looking for code sections, if none, then skip ABI checks.

2019-03-21RISC-V: Fix linker crash in section symbol check.Jim Wilson2-1/+9
sym is only set for local symbols. h is only set for global symbols. Gas won't let me create a global section symbol, but bfd appears to have some support for that, and I can't rule out that other assemblers might do this. So we need to support both, and verify sym and h are non-NULL before using. bfd/ PR 24365 * elfnn-riscv.c (riscv_elf_relocate_section): For STT_SECTION check, verify sym non-NULL before using. Add identical check using h.
2019-03-21[BFD, AArch64, x86] Improve warning for --force-btiSudakshina Das7-14/+45
The AArch64 linker option to turn on BTI (--force-bti) warns in case there are input objects which have a missing GNU NOTE section for BTI. This patch is trying to improve the warnings that come out. In order to do so, I propose adding a new argument to elf_merge_gnu_properties and the backend function merge_gnu_properties. This new argument makes sure that we now pass both the objects along with the properties to which they belong to. The x86 backend function has also been updated to match this change. *** bfd/ChangeLog *** 2019-03-21 Sudakshina Das <sudi.das@arm.com> * elf-bfd.h (struct elf_backend_data): Add argument to merge_gnu_properties. * elf-properties.c (elf_merge_gnu_properties): Add argument to itself and while calling bed->merge_gnu_properties.

This patch add support for elf_backend_fixup_gnu_properties for GNU property support for AArch64.

2019-03-18PR24355, segmentation fault in function called from ppc_finish_symbolsAlan Modra2-6/+9
This one looks to be a bug going back to 2009, git commit e054468f6c "STT_GNU_IFUNC support for PowerPC". That bug was carried over with git commit 49c09209d0 "Rearrange PLT reloc output on powerpc". If the refcount for an ifunc local sym plt entry was zero, ppc_elf_size_dynamic_sections would correctly set plt.offset to -1 but leave glink_offset uninitialized. That leads to occasional segfaults (which can be made solid with MALLOC_PERTURB_=1 when using glibc). So, guard the write_glink_stub call with plt.offset != -1. Also, remove the totally ineffective attempt at writing multiple-use glink stubs only once. PR 24355 * elf32-ppc.c (ppc_finish_symbols): Don't call write_glink_stub for local iplt syms with ent->plt.offset == -1. Remove ineffective attempt at writing glink stubs only once.
