Alan Modra 8a2058b5e3 PR 20472, PowerPC64 ifunc confusion 
This patch fixes quite a lot of confusion in allocate_dynrelocs over
ifuncs.  Function descriptors make ELFv1 quite different to ELFv2.

	PR 20472
	* elf64-ppc.c (ppc64_elf_before_check_relocs): Tweak abiversion test.
	(readonly_dynrelocs): Comment fix.
	(global_entry_stub): New function.
	(ppc64_elf_adjust_dynamic_symbol): Tweak abiversion test.  Match
	ELFv2 code deciding on dynamic relocs vs. global entry stubs to
	that in size_global_entry_stubs, handling ifunc too.  Delete dead
	weak sym code.
	(allocate_dynrelocs): Ensure dyn_relocs field is cleared when no
	dyn_relocs are needed.  Correct handling of ifunc dyn_relocs.
	Tidy ELIMINATE_COPY_RELOCS code, only setting dynindx for
	undefweak syms.  Expand and correct comments.
	(size_global_entry_stubs): Ensure symbol is defined.
	(ppc64_elf_relocate_section): Match condition under which
	dyn_relocs are emitted to that in allocate_dynrelocs.

README

This file contains invisible Unicode characters

This file contains invisible Unicode characters that are indistinguishable to humans but may be processed differently by a computer. If you think that this is intentional, you can safely ignore this warning. Use the Escape button to reveal them.

BFD is an object file library.  It permits applications to use the
same routines to process object files regardless of their format.

BFD is used by the GNU debugger, assembler, linker, and the binary
utilities.

The documentation on using BFD is scanty and may be occasionally
incorrect.  Pointers to documentation problems, or an entirely
rewritten manual, would be appreciated.

There is some BFD internals documentation in doc/bfdint.texi which may
help programmers who want to modify BFD.

BFD is normally built as part of another package.  See the build
instructions for that package, probably in a README file in the
appropriate directory.

BFD supports the following configure options:

  --target=TARGET
	The default target for which to build the library.  TARGET is
	a configuration target triplet, such as sparc-sun-solaris.
  --enable-targets=TARGET,TARGET,TARGET...
	Additional targets the library should support.  To include
	support for all known targets, use --enable-targets=all.
  --enable-64-bit-bfd
	Include support for 64 bit targets.  This is automatically
	turned on if you explicitly request a 64 bit target, but not
	for --enable-targets=all.  This requires a compiler with a 64
	bit integer type, such as gcc.
  --enable-shared
	Build BFD as a shared library.
  --with-mmap
	Use mmap when accessing files.  This is faster on some hosts,
	but slower on others.  It may not work on all hosts.

Report bugs with BFD to bug-binutils@gnu.org.

Patches are encouraged.  When sending patches, always send the output
of diff -u or diff -c from the original file to the new file.  Do not
send default diff output.  Do not make the diff from the new file to
the original file.  Remember that any patch must not break other
systems.  Remember that BFD must support cross compilation from any
host to any target, so patches which use ``#ifdef HOST'' are not
acceptable.  Please also read the ``Reporting Bugs'' section of the
gcc manual.

Bug reports without patches will be remembered, but they may never get
fixed until somebody volunteers to fix them.
