2017-12-06BFD whitespace fixesAlan Modra1-180/+180
Binutils is supposed to use tabs.

2017-11-03x86: Remove func_pointer_refcountH.J. Lu1-17/+22
Since check_reloc is running after gc_sections, there is no need for reference count. If a function pointer relocation can be resolved at run-time, there is no need for PLT and it doesn't count as non-GOT/PLT relocation. func_pointer_refcount can be removed. * elf32-i386.c (elf_i386_check_relocs): Set plt.refcount to 1.

2017-10-10x86: Set GOT refcount to 1H.J. Lu1-3/+3
Since x86 check_relocs is called after opening all inputs and garbage collection, they never see the removed sections. There is no need for incrementing GOT refcount. But since PLT refcount is also used in /* Don't create the PLT entry if there are only function pointer relocations which can be resolved at run-time. */ else if (htab->elf.dynamic_sections_created && (h->plt.refcount > eh->func_pointer_refcount || eh->plt_got.refcount > 0)) { we must increment it. * elf32-i386.c (elf_i386_check_relocs): Set GOT refcount to 1 instead of incrementing it. * elf64-x86-64.c (elf_x86_64_check_relocs): Likewise.

2017-09-09x86: Properly handle __ehdr_startH.J. Lu1-5/+11
After _bfd_i386_elf_convert_load and _bfd_x86_64_elf_convert_load are removed, elf_i386_convert_load_reloc and elf_x86_64_convert_load_reloc see __ehdr_start as an undefined symbol when they are called from check_relocs to convert GOT relocations against local symbols. But __ehdr_start will be defined as a hidden symbol by linker at the later stage if it is referenced.

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.
