From dc11dea21281758b71113c03a8d8be92d175a46c Mon Sep 17 00:00:00 2001 From: "H.J. Lu" Date: Thu, 8 Feb 2018 13:52:22 -0800 Subject: x86: Keep the unused _GLOBAL_OFFSET_TABLE_ for Solaris Solaris requires to keep _GLOBAL_OFFSET_TABLE_ even if it isn't used. This patch detects Solaris target and keeps _GLOBAL_OFFSET_TABLE_ for Solaris. * elf32-i386.c (elf32_i386_copy_solaris_special_section_fields): New prototype. (elf_i386_link_setup_gnu_properties): Set need_global_offset_table for Solaris. * elf64-x86-64.c (elf64_x86_64_copy_solaris_special_section_fields): New prototype. (elf_x86_64_link_setup_gnu_properties): Set need_global_offset_table for Solaris. * elfxx-x86.c (_bfd_x86_elf_size_dynamic_sections): Keep the unused _GLOBAL_OFFSET_TABLE_ for Solaris. (_bfd_x86_elf_link_setup_gnu_properties): Copy need_global_offset_table. * elfxx-x86.h (elf_x86_link_hash_table): Add need_global_offset_table. (elf_x86_init_table): Likewise. --- bfd/elf64-x86-64.c | 9 +++++++++ 1 file changed, 9 insertions(+) (limited to 'bfd/elf64-x86-64.c') diff --git a/bfd/elf64-x86-64.c b/bfd/elf64-x86-64.c index aad9b85..7fa0408 100644 --- a/bfd/elf64-x86-64.c +++ b/bfd/elf64-x86-64.c @@ -27,6 +27,9 @@ #include "opcode/i386.h" #include "elf/x86-64.h" +static bfd_boolean elf64_x86_64_copy_solaris_special_section_fields + (const bfd *, bfd *, const Elf_Internal_Shdr *, Elf_Internal_Shdr *); + #ifdef CORE_HEADER #include #include CORE_HEADER @@ -4858,6 +4861,7 @@ static bfd * elf_x86_64_link_setup_gnu_properties (struct bfd_link_info *info) { struct elf_x86_init_table init_table; + const struct elf_backend_data *bed; if ((int) R_X86_64_standard >= (int) R_X86_64_converted_reloc_bit || (int) R_X86_64_max <= (int) R_X86_64_converted_reloc_bit @@ -4914,6 +4918,11 @@ elf_x86_64_link_setup_gnu_properties (struct bfd_link_info *info) init_table.r_sym = elf32_r_sym; } + bed = get_elf_backend_data (info->output_bfd); + init_table.need_global_offset_table + = (bed->elf_backend_copy_special_section_fields + == elf64_x86_64_copy_solaris_special_section_fields); + return _bfd_x86_elf_link_setup_gnu_properties (info, &init_table); } -- cgit v1.1
