From bb4d2ac2cc637c61232624d9d359b8d3f031e3e9 Mon Sep 17 00:00:00 2001 From: "H.J. Lu" Date: Tue, 25 Nov 2014 06:47:44 -0800 Subject: [PATCH] Display symbol version when dumping dynrelocs Both readelf/objdump know how to get symbol version string for dynamic symbols. This patch extracts this functionality into a separate function and uses it to add symbol version string to versioned symbol names when dumping dynamic relocations. bfd/ PR binutils/16496 * elf-bfd.h (bfd_elf_get_symbol_version_string): New. * elf.c (bfd_elf_get_symbol_version_string): New. Extracted from bfd_elf_print_symbol. (bfd_elf_print_symbol): Use it. binutils/ PR binutils/16496 * objdump.c (objdump_print_symname): Call bfd_elf_get_symbol_version_string to get ELF symbol version string. Append version string if needed. * readelf.c (versioned_symbol_info): New enum. (get_symbol_version_string): New. Extracted from process_symbol_table. (dump_relocations): Add a new argument to indicate if dynamic symbol table is used. Use get_symbol_version_string to get symbol version string for dynamic symbol. Append version string if needed.
