2015-12-01Properly check symbol defined by assignment in linker scriptH.J. Lu1-0/+9
Symbol defined by a linker assignment may have type bfd_link_hash_new or bfd_link_hash_undefined. And h->def_regular is always set. elf_i386_convert_load and elf_x86_64_convert_load should check h->def_regular as well as bfd_link_hash_undefined and bfd_link_hash_new to see if a symbol is defined by a linker script. bfd/ PR ld/19319 * elf32-i386.c (elf_i386_convert_load): Check h->def_regular instead of bfd_link_hash_new. * elf64-x86-64.c (elf_x86_64_convert_load): Likewise.

2015-10-22S/390: ifunc: Redirect local function calls to the IPLT.Andreas Krebbel1-0/+11
bfd/ChangeLog: * elf32-s390.c (elf_s390_check_relocs): Set the non_got_ref marker only when linking an executable. (elf_s390_relocate_section): Redirect PC-relative relocs to a IPLT slot. * elf64-s390.c (elf_s390_check_relocs): Set the non_got_ref marker only when linking an executable. (elf_s390_relocate_section): Redirect PC-relative relocs to a IPLT slot.
2015-10-22S/390: ifunc: Fix function pointers to hidden ifunc symbols.Andreas Krebbel1-0/+6
bfd/ChangeLog: * elf32-s390.c (elf_s390_adjust_dynamic_symbol): Set the PLT reference counters for local IFUNC calls. * elf64-s390.c (elf_s390_adjust_dynamic_symbol): Likewise.
2015-10-22S/390: ifunc: Handle GOTOFF relocs on ifunc symbols.Andreas Krebbel1-0/+9
Normally a GOTOFF reloc only uses the GOT pointer to address something relativ to it without actually requiring a GOT or PLT slot. Things change if the target is an ifunc symbol though. bfd/ChangeLog: * elf32-s390.c (elf_s390_check_relocs): Fallthrough to the PLT slot allocating code for GOTOFF relocs on ifunc symbols. (elf_s390_gc_sweep_hook): Decrement plt refcount for GOTOFF relocs on ifunc symbols. (elf_s390_relocate_section): Redirect a GOTOFF reloc to an iplt slot.
2015-10-22S/390: ifunc: Fix PR18841.Andreas Krebbel1-0/+7
In order to get the ifunc relocs properly sorted the correct class needs to be returned. The code mimics what has been done for x86. bfd/ChangeLog: PR ld/18841 * elf32-s390.c (elf_s390_reloc_type_class): Return reloc_class_ifunc for ifunc symbols. * elf64-s390.c (elf_s390_reloc_type_class): Likewise.
2015-10-22S/390: ifunc: Fix for undefined ifunc symbols.Andreas Krebbel1-0/+6
bfd/ChangeLog: * elf32-s390.c (elf_s390_finish_dynamic_symbol): Call elf_s390_finish_ifunc_symbol only for actually defined symbols. * elf64-s390.c (elf_s390_finish_dynamic_symbol): Likewise.
