+ * reloc.c (BFD_RELOC_PPC_TLSGD, BFD_RELOC_PPC_TLSLD): New.
+ * section.c (struct bfd_section): Add has_tls_get_addr_call.
+ (BFD_FAKE_SECTION): Init new flag.
+ * ecoff.c (bfd_debug_section): Likewise.
+ * bfd-in2.h: Regenerate.
+ * libbfd.h: Regenerate.

+ (ppc_elf_check_relocs): Set has_tls_get_addr_call on finding such
+ without marker relocs.
+ (ppc_elf_tls_optimize): Allow out-of-order __tls_get_addr relocs
+ if section has no old-style calls.
+ (ppc_elf_relocate_section): Set tls_mask for non-tls relocs too.
+ Don't try to optimize new-style __tls_get_addr call when handling

+ relocs.
