+	Introduce TLS descriptors for i386 and x86_64.
+	* reloc.c (BFD_RELOC_386_TLS_GOTDESC, BFD_RELOC_386_TLS_DESC,
+	BFD_RELOC_386_TLS_DESC_CALL, BFD_RELOC_X86_64_GOTPC32_TLSDESC,
+	BFD_RELOC_X86_64_TLSDESC, BFD_RELOC_X86_64_TLSDESC_CALL): New.
+	* libbfd.h, bfd-in2.h: Rebuilt.
+	* elf32-i386.c (elf_howto_table): New relocations.
+	(R_386_tls): Adjust.
+	(elf_i386_reloc_type_lookup): Map new relocations.
+	(GOT_TLS_GDESC, GOT_TLS_GD_BOTH_P): New macros.
+	(GOT_TLS_GD_P, GOT_TLS_GDESC_P, GOT_TLS_GD_ANY_P): New macros.
+	(struct elf_i386_link_hash_entry): Add tlsdesc_got field.
+	(struct elf_i386_obj_tdata): Add local_tlsdesc_gotent field.
+	(elf_i386_local_tlsdesc_gotent): New macro.
+	(struct elf_i386_link_hash_table): Add sgotplt_jump_table_size.

+	(link_hash_newfunc): Initialize tlsdesc_got.
+	(elf_i386_link_hash_table_create): Set sgotplt_jump_table_size.
+	(elf_i386_tls_transition): Handle R_386_TLS_GOTDESC and

+	(elf_i386_gc_sweep_hook): Handle R_386_TLS_GOTDESC and
+	R_386_TLS_DESC_CALL.
+	(allocate_dynrelocs): Count function PLT relocations.  Reserve
+	space for TLS descriptors and relocations.
+	(elf_i386_size_dynamic_sections): Reserve space for TLS
+	descriptors and relocations.  Set up sgotplt_jump_table_size.
+	Don't zero reloc_count in srelplt.
