From 51b64d56a7c65e6a30649cf9aade57b56c321c0e Mon Sep 17 00:00:00 2001 From: Alan Modra Date: Sat, 29 Sep 2001 06:21:59 +0000 Subject: * elf-bfd.h (struct elf_link_local_dynamic_entry): Add init_refcount. (struct elf_backend_data): Add can_refcount. * elf.c (_bfd_elf_link_hash_newfunc): Get rid of a few casts. Set got.refcount and plt.refcount from init_refcount. (_bfd_elf_link_hash_table_init): Set up init_refcount. (_bfd_elf_link_hash_copy_indirect): Reference got/plt.refcount rather than got/plt.offset, and test for <= 0 rather than -1. * elflink.h (size_dynamic_sections): Set init_refcount to -1. * elfxx-target.h (elf_backend_can_refcount): Define. (elfNN_bed): Init can_refcount. * linker.c (_bfd_link_hash_newfunc): Get rid of a few casts. (_bfd_generic_link_hash_newfunc): Likewise. * elf32-cris.c (cris_elf_check_relocs): Modify for refcounts starting from zero. (elf_backend_can_refcount): Define. * elf32-hppa.c (elf32_hppa_check_relocs): Modify for refcounts starting from zero. (elf32_hppa_copy_indirect_symbol): Make static to agree with prototype. (elf_backend_can_refcount): Define. * elf32-i386.c (elf_i386_check_relocs): Modify for refcounts starting from zero. (allocate_dynrelocs): Set plt/got.offset rather than *.refcount. (elf_i386_finish_dynamic_symbol): Expand SHN_UNDEF comment. (elf_i386_finish_dynamic_sections): Use local var so line < 80 chars. (elf_backend_can_refcount): Define. (elf_i386_copy_indirect_symbol): Make static to agree with prototype. Formatting fix. * elf32-m68k.c (elf_m68k_check_relocs): Modify for refcounts starting from zero. (elf_backend_can_refcount): Define. * elf32-ppc.c (ppc_elf_check_relocs): Modify for refcounts starting from zero. (elf_backend_can_refcount): Define. * elf32-s390.c (elf_s390_check_relocs): Modify for refcounts starting from zero. (elf_backend_can_refcount): Define. * elf64-s390.c (elf_s390_check_relocs): Modify for refcounts starting from zero. (elf_backend_can_refcount): Define. * elf64-x86-64.c (elf64_x86_64_check_relocs): Modify for refcounts starting from zero.
