/* The following functions are specific to the ELF linker, while
   functions above are used generally.  Those named ppc64_elf_* are
   called by the main ELF linker code.  They appear in this file more
   or less in the order in which they are called.  eg.
   ppc64_elf_check_relocs is called early in the link process,
   ppc64_elf_finish_dynamic_sections is one of the last functions
   called.

   PowerPC64-ELF uses a similar scheme to PowerPC64-XCOFF in that
   functions have both a function code symbol and a function descriptor
   symbol.  A call to foo in a relocatable object file looks like:

   .		.text
   .	x:
   .		bl	.foo
   .		nop

   The function definition in another object file might be:

   .		.section .opd
   .	foo:	.quad	.foo
   .		.quad	.TOC.@tocbase
   .		.quad	0
   .
   .		.text
   .	.foo:	blr

   When the linker resolves the call during a static link, the branch
   unsurprisingly just goes to .foo and the .opd information is unused.
   If the function definition is in a shared library, things are a little
   different:  The call goes via a plt call stub, the opd information gets
   copied to the plt, and the linker patches the nop.

   .	x:
   .		bl	.foo_stub
   .		ld	2,40(1)
   .
   .
   .	.foo_stub:
   .		addis	12,2,Lfoo@toc@ha	# in practice, the call stub
   .		addi	12,12,Lfoo@toc@l	# is slightly optimized, but
   .		std	2,40(1)			# this is the general idea
   .		ld	11,0(12)
   .		ld	2,8(12)
   .		mtctr	11
   .		ld	11,16(12)
   .		bctr
   .
   .		.section .plt
   .	Lfoo:	reloc (R_PPC64_JMP_SLOT, foo)

   The "reloc ()" notation is supposed to indicate that the linker emits
   an R_PPC64_JMP_SLOT reloc against foo.  The dynamic linker does the opd
   copying.

   What are the difficulties here?  Well, firstly, the relocations
   examined by the linker in check_relocs are against the function code
   sym .foo, while the dynamic relocation in the plt is emitted against
   the function descriptor symbol, foo.  Somewhere along the line, we need
   to carefully copy dynamic link information from one symbol to the other.
   Secondly, the generic part of the elf linker will make .foo a dynamic
   symbol as is normal for most other backends.  We need foo dynamic
   instead, at least for an application final link.  However, when
   creating a shared library containing foo, we need to have both symbols
   dynamic so that references to .foo are satisfied during the early
   stages of linking.  Otherwise the linker might decide to pull in a
   definition from some other object, eg. a static library.

   Update: As of August 2004, we support a new convention.  Function
   calls may use the function descriptor symbol, ie. "bl foo".  This
   behaves exactly as "bl .foo".  */

   decides to copy as dynamic relocs in check_relocs for each symbol.

   enabled;  In the PowerPC64 ABI, the address of a function is actually
   the address of a function descriptor, which resides in the .opd
   section.  gcc uses the descriptor directly rather than going via the
   GOT as some other ABI's do, which means that initialized function
   pointers must reference the descriptor.  Thus, a function pointer
   initialized to the address of a function in a shared library will
   either require a copy reloc, or a dynamic reloc.  Using a copy reloc
   redefines the function descriptor symbol to point to the copy.  This
   presents a problem as a plt entry for that function is also
   initialized from the function descriptor symbol and the copy reloc

   For a defined function "foo" and an undefined call to "bar":

   A new object defines "foo" and references "bar".

   A new object thus has no problem with its undefined symbols being
