b07bca4ecd Wrong function reported for linker error message 
OPD lookup goes awry when .opd has been shuffled to remove unused
functions.

	* elf64-ppc.c (ppc64_elf_maybe_function_sym): Adjust symbol value
	if .opd section has been edited.

a4b6fadd50 ppc64 out-of-line register save/restore functions 
Don't emit long branch or plt branch stubs to save/restore functions.
Copy them instead.  The problem is that plt branch stubs currently
trash r12, one of the parameters to some of the save/restore
functions, and there is no free register available to use instead of
r12.

6f20ed8a is prerequisite for this patch.

	PR 18878
	* elf64-ppc.c (ARRAY_SIZE): Define.  Use throughout.
	(enum ppc_stub_type): Add ppc_stub_save_res.
	(struct map_stub): Add "next" and "needs_save_res".
	(struct ppc_link_hash_entry): Add "save_res" flag.
	(struct ppc_link_hash_table): Add "group".
	(sfpr_define): Add stub_sec param.  Define symbol in stub_sec if
	stub_sec is non-null.  Set "save_res".
	(save_res_funcs): Make file scope, rename from funcs.  Adjust uses.
	(ppc64_elf_adjust_dynamic_symbol): Prohibit plt call to save_res syms.
	(ppc_build_one_stub): Handle ppc_stub_save_res.
	(ppc_size_one_stub): Set stub type to ppc_size_one_stub on finding
	stub for linker defined save_res sym.
	(group_sections): Init new fields of struct map_stub.
	(ppc64_elf_size_stubs): Reserve space for save/restore func copy.
	(ppc64_elf_build_stubs): Copy save/restore funcs to groups.  Emit
	alias syms too.
	(ppc64_elf_relocate_section): Set destination for ppc_stub_save_res.

a7c4979727 Optimise PowerPC64 r2 adjusting stubs 
Sometimes these stubs don't need to change the low 16-bits of r2, so in
that case omit a useless addi r2,r2,0 insn.  Also, change the get_r2off
error return from 0 to -1 since 0 is a valid return for ELFv2 -R objects.

	* elf64-ppc.c (get_r2off): Return -1 on error.
	(ppc_build_one_stub): Adjust for get_r2off change.  Don't emit
	addi r2,r2,0 on r2off stubs when the low 16-bit delta is zero.
	(ppc_size_one_stub): Corresponding size changes for r2off stubs.
	Add condition in test for -R objects.

6f20ed8a6b ppc64 section group handling 
Two organizational changes to the array of additional info kept for
sections.
1) Move group info into a per-group allocated struct, in preparation
for future changes that need per-group accounting.
2) Expand the array to include output sections, which simplifies
sizing and removes the need for a separate output section array.

	* section.c (section_id): Make file scope.
	(bfd_get_next_section_id): New function.
	* elf64-ppc.c (struct map_stub): Remove toc_off field.  Move decl.
	(struct ppc_stub_hash_entry): Delete stub_sec and id_sec.  Add
	group.  Update all uses.
	(struct ppc_link_hash_table): Delete top_id, top_index, and
	input_list.  Add sec_info_arr_size.  Rename stub_group to
	sec_info, and make group info indirect.  Update stub_group refs
	throughout file.
	(ppc_add_stub): Don't look for stub_sec on link_sec stub_group
	entry.
	(ppc_build_one_stub): Delete FIXME.
	(ppc64_elf_setup_section_lists): Size htab->sec_info for all
	sections, not just input sections.  Don't create htab->input_list.
	(ppc64_elf_next_input_section): Update to use sec_info union as
	list pointer.
	(PREV_SEC): Delete.
	(group_sections): Pass "info" param rather than "htab".  Iterate
	over output sections rather than input_list.  Use sec_info union
	as list pointers.  Alloc atruct map_stub, and return fail status.
	* bfd-in2.h: Regenerate.

44b4145b72 [AArch64] Cleanup TLS relocation types which don't go through GOT table 
This patch done two types of cleanup:

  * in aarch64_reloc_got_type and elfNN_aarch64_relocate_section

    We don't need those redundant "case" check, as they can be merged
    with the "default" which just "break".

  * in elfNN_aarch64_gc_sweep_hook and elfNN_aarch64_check_relocs

    All TLS local executable relocations and some local dynamic
    relocations (those calculate module offset) actually don't need GOT
    entry, so remove them from GOT entry counting.

0e1862bb40 Add output_type to bfd_link_info 
The "shared" field in bfd_link_info is set for both DSO and and PIE.
There are separate fields for executable and relocatable outputs.  This
patch adds an "output_type" field:

enum output_type
{
  type_unknown = 0,
  type_executable,
  type_dll,
  type_relocatable
};

and a "pic" field to bfd_link_info to replace shared, executable and
relocatable fields so that we can use the "output_type" field to check
for output type and the "pic" field check if output is PIC.  Macros,
bfd_link_executable, bfd_link_dll, bfd_link_relocatable, bfd_link_pic
and bfd_link_pie, are provided to check for output features.

8efa2874ab Issue an error for read-only segment with dynamic IFUNC relocations 
To load an ELF binary with DT_TEXTREL tag, the dynamic linker calls
__mprotect on the read-only segment with PROT_READ|PROT_WRITE before
applying dynamic relocation.  It leads to segfault when performing
IFUNC relocations since the read-only segment has no execute permission.
This patch changes x86 linker to issue an error for read-only segment
with dynamic IFUNC relocations.  Other backends with IFUNC support
may need a similar change.

Since the backend elf_add_symbol_hook isn't called on local symbols,
