* elf64-ppc.c (struct ppc_dyn_relocs): New.

	(IS_ABSOLUTE_RELOC): Define.
	(struct ppc_link_hash_entry): New.
	(struct ppc_link_hash_table): New.
	(ppc_hash_table): Define.
	(link_hash_newfunc): New function.
	(ppc64_elf_link_hash_table_create): New function.
	(create_got_section): New function.
	(ppc64_elf_create_dynamic_sections): Call create_got_section.  Stash
	pointers to our dynamic sections in hash table.
	(ppc64_elf_copy_indirect_symbol): New function.
	(ppc64_elf_check_relocs): Remove DEBUG code.  Use short-cuts to
	dynamic sections.  Localise vars.  Modify code for refcounts
	starting from zero.  Don't allocate here, or force symbols dynamic.
	Don't copy all relocs if shared, select ones we need.  Add code
	to track possible copy relocs for non-shared link.
	(ppc64_elf_gc_mark_hook): Update comment.
	(ppc64_elf_gc_sweep_hook): Sweep dynrelocs too.
	(ppc64_elf_adjust_dynamic_symbol): Remove DEBUG code.  Rewrite .plt
	code for reference counting garbage collection.  Don't create .plt
	entries for functions that don't comply with ABI naming convention,
	and don't allocate .plt space here.  Use short-cuts to dynamic
	sections.  If possible, keep dynamic relocations instead of using
	copy relocs.  Remove confused comments.
	(ppc_adjust_dynindx): Delete.
	(WILL_CALL_FINISH_DYNAMIC_SYMBOL): Define.
	(allocate_dynrelocs): New function.
	(readonly_dynrelocs): New function.
	(ppc64_elf_size_dynamic_sections): Rewrite.  Allocate local .got
	space here, and call allocate_dynrelocs to allocate space for
	global .plt, .got and reloc sections.  Use short-cuts to dynamic
	sections.  Call readonly_dynrelocs to determine whether we need
	DT_TEXTREL.  Don't generate section symbols here, the generic
	ELF linker code does it for us.
	(ppc64_elf_final_link): Call regular ELF backend linker rather than
	gc variety, since we do our own .got handling.
	(ppc64_elf_relocate_section): Remove DEBUG code.  Make use of
	dynamic section short-cuts.  Localise vars, and delay setting.
	Handle unknown relocs in main switch statement.  Replace ugly
	complicated tests for unresolvable relocs with a simple direct
	scheme using "unresolved_reloc" var.  Test ELF_ST_VISIBILITY
	before allowing an undefined sym in a shared lib.  Do R_*_DS tests
	after main switch, when we've set addend.  Do non-addend insn
	tweaks before main swithc.  Ignore input_section->vma when
	calculating reloc offsets as it's always zero.  Rewrite dynamic
	reloc handling.  Consolidate R_*_HA handling.  Handle more relocs.
	(ppc64_elf_finish_dynamic_symbol): Remove DEBUG code.  Make use
	of dynamic section short-cuts.  Reorganise .plt handling code.
	Remove confused comments.  Take note of ELF_LINK_FORCED_LOCAL.
	Move expressions out of swap_reloca_out function calls.
	(ppc64_elf_reloc_type_class): New function.
	(ppc64_elf_info_to_howto): Move common expression to local var.
	(ppc64_elf_finish_dynamic_sections): Remove DEBUG code.  Make use
	of dynamic section short-cuts.  Don't fiddle with section syms
	here as the ELF linker does it for us.
	(elf_backend_can_refcount): Define.
	(bfd_elf64_bfd_link_hash_table_create): Define.
	(elf_backend_copy_indirect_symbol): Define.
	(elf_backend_reloc_type_class): Define.
	(elf_backend_*, bfd_elf64_bfd_* defines): Sort.

-	 point comparison work as expected within one object, but not
-	 across object boundaries.  From the ABI:
-
- In this ABI, the address of a function is actually the address of a
- function descriptor.  A reference to a function, other than a function
- call, will normally load the address of the function descriptor from
- the global offset table.  The dynamic linker will ensure that for a
- given function, the same address is used for all references to the
- function from any global offset table.  Thus, function address
- comparisons will work as expected.
-
- When making a call to the function, the code may refer to the
- procedure linkage table entry, in order to permit lazy symbol
- resolution at run time.  In order to support correct function address
- comparisons, the compiler should be careful to only generate
- references to the procedure linkage table entry for function calls.
- For any other use of a function, the compiler should use the real
- address.
-
-	 I don't see how this could ever work when passing a pointer to
-	 a function across an object boundary.  The compiler has no
-	 way of knowing how to find the function descriptor for a
-	 function whose entrypoint is taken as an argument.
-
-	 Or should the compiler arrange so that the function descriptor
-	 address is passed and make the callee dig out the entry point
-	 from that?  */
