Alan Modra 8c5b4e5228 PowerPC64 dot-symbol compatibility bugfixes
Lots of fixes for the compatibility code that handles linking of
-mcall-aixdesc code (or that generated by 12 year old gcc) with
current ELFv1 ABI code.

1) A reference to a dot-symbol in an object file wasn't satisfied by a
   function descriptor in later object files.
2) The as-needed code had bit-rotted;  Shared libs now need a strong
   reference to be counted as needed.
3) --gc-sections involving dot-symbols was broken, needing
   func_desc_adjust to be run early and lots of other fixes.

bfd/
	* elf64-ppc.c (struct ppc_link_hash_entry): Delete "was_undefined".
	(struct ppc_link_hash_table): Delete "twiddled_syms".  Add
	"need_func_desc_adj".
	(lookup_fdh): Link direct fdh sym via oh field and set flags.
	(make_fdh): Make strong and weak undefined function descriptor
	symbols.
	(ppc64_elf_merge_symbol): New function.
	(elf_backend_merge_symbol): Define.
	(ppc64_elf_archive_symbol_lookup): Don't test undefweak for fake
	function descriptors.
	(add_symbol_adjust): Don't twiddle symbols to undefweak.
	Propagate more ref flags to function descriptor symbol.  Make
	some function descriptor symbols dynamic.
	(ppc64_elf_before_check_relocs): Only run add_symbol_adjust for
	ELFv1.  Set need_func_desc_adj.  Don't fix undefs list.
	(ppc64_elf_check_relocs): Set non_ir_ref for descriptors.
	Don't call lookup_fdh here.
	(ppc64_elf_gc_sections): New function.
	(bfd_elf64_bfd_gc_sections): Define.
	(ppc64_elf_gc_mark_hook): Mark descriptor.
	(func_desc_adjust): Don't make fake function descriptor syms strong
	here.  Exit earlier on non-dotsyms.  Take note of elf.dynamic
	flag when deciding whether a dynamic function descriptor might
	be needed.  Transfer elf.dynamic and set elf.needs_plt.  Move
	plt regardless of visibility.  Make descriptor dynamic if
	entry sym is dynamic, not for other cases.
	(ppc64_elf_func_desc_adjust): Don't run func_desc_adjust if
	already done.
	(ppc64_elf_edit_opd): Use oh field rather than lookup_fdh.
	(ppc64_elf_size_stubs): Likewise.
	(ppc_build_one_stub): Don't clear was_undefined.  Only set sym
	undefweak if stub symbol is defined.
	(undo_symbol_twiddle, ppc64_elf_restore_symbols): Delete.
	* elf64-ppc.h (ppc64_elf_restore_symbols): Don't declare.
ld/
	* emultempl/ppc64elf.em (gld${EMULATION_NAME}_finish): Don't call
	ppc64_elf_restore_symbols.
	* testsuite/ld-powerpc/dotsym1.d: New.
	* testsuite/ld-powerpc/dotsym2.d: New.
	* testsuite/ld-powerpc/dotsym3.d: New.
	* testsuite/ld-powerpc/dotsym4.d: New.
	* testsuite/ld-powerpc/dotsymref.s: New.
	* testsuite/ld-powerpc/nodotsym.s: New.
	* testsuite/ld-powerpc/powerpc.exp: Run new tests.

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.
