* elf32-ppc.c (ppc_elf_check_relocs): Always set up sections
used by indirect function support. Count dynamic relocs for ifunc syms. (ppc_elf_adjust_dynamic_symbol): Tweak for ifunc. (allocate_dynrelocs): Allocate all non-dynamic ifunc plt entries in iplt and their relocs in reliplt. Don't make ifunc syms dynamic. Allocate got entry relocs for non-dynamic ifunc in reliplt. Handle other dynamic relocs for ifunc. (ppc_elf_size_dynamic_sections): Alloc dyn relocs for static ifunc in reliplt, likewise relocs for got against local ifunc. Typo fix on reliplt size adjust. (ppc_elf_relocate_section): Don't use plt scheme of allocating relocs 1-1 with entries for iplt, instead just add using reloc_count. Write got relocs and dyn relocs for ifunc to reliplt. Error on invalid ifunc dyn relocs. (ppc_elf_finish_dynamic_symbol): Adjust for non-dynamic ifunc plt in iplt/reliplt. * elf64-ppc.c (ppc64_elf_howto_raw): Add R_PPC64_JMP_IREL, R_PPC64_REL16, R_PPC64_REL16_LO, R_PPC64_REL16_HI, R_PPC64_REL16_HA. (ppc64_elf_reloc_type_lookup): Handle new relocs. (ppc64_elf_check_relocs): Likewise. Count dyn relocs for ifunc. (allocate_dynrelocs): As for elf32-ppc.c above. (ppc64_elf_size_dynamic_sections): Likewise. (ppc_build_one_stub): Put non-dynamic ifunc plt call stubs in iplt, and their relocs in reliplt. Use R_PPC64_JMP_IREL. (ppc_size_one_stub): Similarly. (ppc64_elf_relocate_section): As for elf32-ppc.c above. Handle new relocs too. (ppc64_elf_finish_dynamic_symbol): As for elf32-ppc.c above.
