2017-09-03x86-64: Set tlsdesc_plt if GOT_TLS_GDESC_P is trueH.J. Lu2-1/+11
We need to set tlsdesc_plt for x86-64 if GOT_TLS_GDESC_P is true when allocating dynamic relocations so that _bfd_x86_elf_size_dynamic_sections will generate TLSDESC_PLT and TLSDESC_GOT in x86-64 output. bfd/ PR ld/22071 * elfxx-x86.c (elf_x86_allocate_dynrelocs): Set tlsdesc_plt for x86-64 if GOT_TLS_GDESC_P is true. ld/ PR ld/22071 * testsuite/ld-x86-64/pr22071.d: New file. * testsuite/ld-x86-64/pr22071.s: Likewise. * testsuite/ld-x86-64/x86-64.exp: Run pr22071.

2017-09-02x86: Add _bfd_x86_elf_size_dynamic_sectionsH.J. Lu4-815/+483
elf_i386_size_dynamic_sections and elf_x86_64_size_dynamic_sections are very similar, except for the followings: 1. elf_i386_size_dynamic_sections checks GOT_TLS_IE and GOT_TLS_IE_BOTH. elf_x86_64_size_dynamic_sections checks only GOT_TLS_IE. Since GOT_TLS_IE_BOTH is never true for x86-64, it is OK to check GOT_TLS_IE for both i386 and x86-64. 2, x86-64 sets tlsdesc_plt, but i386 doesn't. We set tlsdesc_plt only if target_id == X86_64_ELF_DATA. 3. x86-64 has if (s != htab->elf.srelplt) s->reloc_count = 0; and i386 has s->reloc_count = 0; i386 did have if (s != htab->srelplt) s->reloc_count = 0; in the original commit: commit 67a4f2b710581acc83afecff55424af285ecbc28 Author: Alexandre Oliva <aoliva@redhat.com> Date: Wed Jan 18 21:07:51 2006 +0000 But it was removed by commit 5ae0bfb60a576344d7f701605346282c1144499e Author: Richard Sandiford <rdsandiford@googlemail.com> Date: Tue Feb 28 07:16:12 2006 +0000 bfd/ * elf32-i386.c (elf_i386_link_hash_table): Add next_tls_desc_index.

So it is correct to use if (s != htab->elf.srelplt) s->reloc_count = 0; for both i386 and x86-64 now. 4. i386 and x86-64 use different DT_XXXs. They are handled by adding them to elf_x86_link_hash_table.

The howto for R_FT32_18 was using complain_overflow_signed. But some valid address calculations exceed the range of this reloc. Changing it to complain_overflow_dont allows them. bfd/ChangeLog: * elf32-ft32.c (ft32_elf_howto_table): Use complain_overflow_dont for R_FT32_18.
2017-08-31bfd_close_all_done calling _close_and_cleanupAlan Modra2-15/+10
elf64_vms_close_and_cleanup calls bfd_get_size, which calls iovec->bstat. cache_bstat ends up adding the bfd to the cache lru list, negating the bfd_cache_close call in bfd_close_all_done. So there is a dangling pointer into the freed and then reused bfd. Thus, bfd_cache_close must be called after _close_and_cleanup, or better, via iovec->bclose. PR binutils/22032 * opncls.c (bfd_close_all_done): Don't call bfd_cache_close before _close_and_cleanup. Call iovec->bclose after. (bfd_close): Remove code common to, and call, bfd_close_all_done.
