* elf32-ppc.c (ppc_elf_tls_optimize): Catch more cases where
	old-style __tls_get_addr calls without marker relocs don't match
	their arg setup insn one for one.  If such mismatches are found
	report the reloc and don't do any tls optimization.
	* elf64-ppc.c (ppc64_elf_tls_optimize): Likewise.

* ppc.h (R_PPC_TLSGD, R_PPC_TLSLD): Add new relocs.
	* ppc64.h (R_PPC64_TLSGD, R_PPC64_TLSLD): Add new relocs.
bfd/
	* 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.
	* elf32-ppc.c (ppc_elf_howto_raw): Add R_PPC_TLSGD and R_PPC_TLSLD.
	(ppc_elf_reloc_type_lookup): Handle new relocs.
	(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
	arg setup relocs.  Instead do so for R_PPC_TLSGD and R_PPC_TLSLD
	relocs.
	* elf64-ppc.c (ppc64_elf_howto_raw): Add R_PPC64_TLSGD, R_PPC64_TLSLD.

	without marker relocs.
	(ppc64_elf_tls_optimize): Allow out-of-order __tls_get_addr relocs
	if section has no old-style calls.  Set toc_ref for new relocs as
	appropriate.
	(ppc64_elf_relocate_section): Set tls_mask for non-tls relocs too.
	Don't try to optimize new-style __tls_get_addr call when handling
	arg setup relocs.  Instead do so for R_PPC_TLSGD and R_PPC_TLSLD
	relocs.
gas/
	* config/tc-ppc.c (ppc_elf_suffix): Error if ppc32 tls got relocs
	have non-zero addend.
