(TLS_GD): ..define this instead and update all uses. (TLS_TPRELGD): Define. (ppc64_elf_link_hash_table_create): Tweak initialization of init_refcount and init_offset. (ppc64_elf_check_relocs): Add one extra element to t_symndx array. Mark second slot of GD or LD toc entries. (get_tls_type): Return an int. Distinguish toc GD and LD entries from other tls types. (ppc64_elf_tls_setup): New function, split out from.. (ppc64_elf_tls_optimize): ..here. Don't optimize when symbols are defined in a dynamic object. Fix LD optimization. Don't set TLS_TPREL on GD->IE optimization, use TLS_TPRELGD instead. Use get_tls_type return value to properly decide whether toc GD and LD entries can optimize away __tls_get_addr call. Check next reloc after DTPMOD64 to determine GD or LD rather than looking at TLS_LD flag. Don't attempt to adjust got entry tls_type here.. (allocate_dynrelocs): ..instead, adjust got entry tls_type here, and look for possible merges. (ppc64_elf_size_dynamic_sections): Adjust local got entries for optimization. (ppc64_elf_size_stubs): Tweak __tls_get_addr fudge. (ppc64_elf_relocate_section): Rename some vars to better reflect usage. Make use of return value from get_tls_type to properly detect GD and LD optimizations. Split tlsld/gd hi/ha from lo/ds case. Don't handle tls_get_addr removal when looking at REL24 relocs, do it when looking at the previous reloc. Check reloc after DTPMOD64 to determine GD or LD. * elf64-ppc.h (ppc64_elf_tls_setup): Declare.
