+ * elf-bfd.h (_bfd_elf_allocate_ifunc_dyn_relocs): Add an
+ bfd_boolean argument.
+ * elf-ifunc.c (_bfd_elf_create_ifunc_sections): Replace
+ "shared object" with "PIC object" in comments.
+ (_bfd_elf_allocate_ifunc_dyn_relocs): Updated. Replace
+ "shared object" with "PIC object" in comments. Avoid PLT if
+ requested. Generate dynamic relocations for non-GOT references.
+ Make room for the special first entry in PLT and allocate PLT
+ entry only for PLT and PC-relative references. Store dynamic
+ GOT relocations in .rel[a].iplt section for static executables.
+ If PLT isn't used, always use GOT for symbol value. Don't
+ allocate GOT entry if it isn't used.
+ * elf32-i386.c (elf_i386_check_relocs): Increment PLT reference
+ count only in the code section. Allocate dynamic pointer
+ relocation against STT_GNU_IFUNC symbol in the non-code section.
+ (elf_i386_adjust_dynamic_symbol): Increment PLT reference count
+ only for PC-relative references.
+ (elf_i386_allocate_dynrelocs): Pass TRUE to
+ _bfd_elf_allocate_ifunc_dyn_relocs.
+ (elf_i386_relocate_section): Allow R_386_GOT32/R_386_GOT32X
+ relocations against STT_GNU_IFUNC symbols without PLT. Generate

+ the non-code section and store it in the proper REL section.
+ Don't allow non-pointer relocation against STT_GNU_IFUNC symbol
+ without PLT.
