+ * elf64-ppc.h (struct ppc64_elf_params): Add no_tls_get_addr_regsave.
+ * elf64-ppc.c (struct ppc_link_hash_table): Add tga_desc and
+ tga_desc_fd.
+ (is_tls_get_addr): Match tga_desc and tga_desc_df too.
+ (STDU_R1_0R1, ADDI_R1_R1): Define.
+ (tls_get_addr_prologue, tls_get_addr_epilogue): New functions.
+ (ppc64_elf_tls_setup): Set up tga_desc and tga_desc_fd. Indirect
+ tga_desc_fd to opt_fd, and tga_desc to opt. Set
+ no_tls_get_addr_regsave.
+ (branch_reloc_hash_match): Add hash3 and hash4.
+ (ppc64_elf_tls_optimize): Handle tga_desc_fd and tga_desc too.
+ (ppc64_elf_size_dynamic_sections): Likewise.
+ (ppc64_elf_relocate_section): Likewise.
+ (plt_stub_size, build_plt_stub): Likewise. Size regsave
