From 37bb890f814d58dd4c5f67db32ea4618008229ee Mon Sep 17 00:00:00 2001 From: Alan Modra Date: Mon, 29 Mar 2021 09:39:15 +1030 Subject: ELF output symbol hooks int vs. bfd_boolean elf_backend_link_output_symbol_hook and elf_link_output_symstrtab may return 2 when a symbol is to be discarded. Update places that use bfd_boolean rather than int for these functions. * elflink.c (elf_link_output_symstrtab): Make flinfo parameter a void pointer. (bfd_elf_final_link): Delete out_sym_func typedef and don't cast elf_link_output_symstrtab when calling output_arch_syms and output_arch_local_syms. * elf-bfd.h (struct elf_backend_data ): Change return type of func arg to match elf_link_output_symstrtab. * elf-vxworks.h (elf_vxworks_link_output_symbol_hook): Correct return type. * elf32-nds32.c (nds32_elf_output_symbol_hook): Correct return type. (nds32_elf_output_arch_syms): Correct func return type. --- bfd/ChangeLog | 15 +++++++++++++++ bfd/elf-bfd.h | 8 ++++---- bfd/elf-vxworks.h | 2 +- bfd/elf32-nds32.c | 10 +++++----- bfd/elflink.c | 17 ++++------------- 5 files changed, 29 insertions(+), 23 deletions(-) diff --git a/bfd/ChangeLog b/bfd/ChangeLog index 1fbbe3361d..5cdb6c8731 100644 --- a/bfd/ChangeLog +++ b/bfd/ChangeLog @@ -1,3 +1,18 @@ +2021-03-29 Alan Modra + + * elflink.c (elf_link_output_symstrtab): Make flinfo parameter + a void pointer. + (bfd_elf_final_link): Delete out_sym_func typedef and don't cast + elf_link_output_symstrtab when calling output_arch_syms and + output_arch_local_syms. + * elf-bfd.h (struct elf_backend_data ): Change return type of func + arg to match elf_link_output_symstrtab. + * elf-vxworks.h (elf_vxworks_link_output_symbol_hook): Correct + return type. + * elf32-nds32.c (nds32_elf_output_symbol_hook): Correct return type. + (nds32_elf_output_arch_syms): Correct func return type. + 2021-03-29 Alan Modra * elf-m10200.c (mn10200_elf_relocate_section): Return int. diff --git a/bfd/elf-bfd.h b/bfd/elf-bfd.h index 04785a814e..dec6925fd4 100644 --- a/bfd/elf-bfd.h +++ b/bfd/elf-bfd.h @@ -1259,16 +1259,16 @@ struct elf_backend_data not handled in the hash table. */ bfd_boolean (*elf_backend_output_arch_local_syms) (bfd *, struct bfd_link_info *, void *, - bfd_boolean (*) (void *, const char *, Elf_Internal_Sym *, asection *, - struct elf_link_hash_entry *)); + int (*) (void *, const char *, Elf_Internal_Sym *, asection *, + struct elf_link_hash_entry *)); /* This function, if defined, is called after all symbols are emitted into the symtab section.
