Fix generic linker symbol output when weak is overridden by strong

Yes, I know this also affects bfd_link_hash_indirect, but output of
indirect and warning symbols looks quite broken anyway.

	* linker.c (_bfd_generic_link_output_symbols): Remove BSF_WEAK
	flag from bfd_link_hash_defined symbols.
Reverts an "enhancement" made in a previous delta which complained of
unprocessed augmentation data at the end of a CIE.

	* dwarf.c (read_cie): Revert check for unused augmentation data -
	it was bogus.
This patch adds support for printing out the pdata section of PE objects.

	* pe-x86_64.c (pex64_bfd_print_pdata): Add external
	declaration.
	(bfd_pe_print_data): Set macro to pex64_bfd_print_data.
	* pei-x86_64.c (pex64_bfd_print_pdata): Changed to
	global function. Now handles multiple .pdata sections.
	(pex_bfd_print_pdata_section): New static helper function,
	using most of old pex_bfd_print_pdata function code, but adding
	support for coff pe objects, which might have some fields
	starting at zero offset.
	(pex64_print_all_pdata_sections) : New static helper function,
	used in call to bfd_map_over_sections inside new
	pex66_bfd_print_pdata function.
	(bfd_boolean pdata_count): New static variable, used to return
	bfd_boolean value for pex64_bfd_print_pdata function.
Don't create .eh_frame_hdr on shared lib bfd

If no object files have .eh_frame, but some shared library does, then
ld creates a .eh_frame_hdr section using the shared library bfd.  This
is silly since shared library .eh_frame sections don't contribute to
the output .eh_frame and thus no .eh_frame_hdr is needed.

Also, the bfd section list and count is cleared for shared libraries,
and a zero section count used as a flag in lang_check to omit a call
to bfd_merge_private_bfd_data for shared libraries.  If we create a
section on a shared lib bfd then ld will wrongly attempt to merge the
shared library private bfd data.

	PR 17742
	* ld/emultempl/elf32.em (gld${EMULATION_NAME}_after_open): Exclude
	shared libraries in loop looking for .eh_frame sections.
	Similarly for build-id loop.
Add mul.x and umul.x instructions to moxie port
Add support for moxie's mul.x and umul.x instructions
This patch fixes a snafu where the -D and -U short versions of the
--enable-deterministic-archives and --disable-deteministic-archive
options were not being accepted.

	PR binutils/17671
	* objcopy.c (copy_main, strip_main): Add D and U to the list of
	accepted short versions of long options.
AVR: Assembler now prepares for linker relaxation by default.

Have the assembler prepare for linker relaxation by default.  This
means that users will be able to make use of linker relaxation without
having to adjust the assembler flags, this can make life easier when
compiling libraries.

Having this on by default in the assembler should make no difference to
the assembler code produced, however, some of the debug information will
be slightly less compressed.

A few tests needed to be updated as a result of this change as they
relied on linker relaxation support being off by default.

I've tightened up the definition of which sections can be relaxed on AVR
as part of this commit, the assembler used to think that all
non-debugging sections could be relaxed, when in reality only code
sections can be relaxed for AVR.  The previous definition was not
dangerous, just over cautious.  The new tighter definition allows an
extra test (gas/testsuite/gas/all/forward.d) to continue to pass.

gas/ChangeLog:

	* config/tc-avr.c (struct avr_opt_s): Change link_relax to
	no_link_relax, extend comment.
	(enum options): Add new OPTION_NO_LINK_RELAX.
	(md_longopts): Add entry for -mno-link-relax.
	(md_parse_option): Handle OPTION_NO_LINK_RELAX, and update
	OPTION_LINK_RELAX.
	(md_begin): Initialise linkrelax from no_link_relax.
	(md_show_usage): Include -mno-link-relax option.
	(relaxable_section): Only allocatable code sections can be
	relaxed.
	* config/tc-avr.h (TC_LINKRELAX_FIXUP): Define.

gas/testsuite/ChangeLog:

	* gas/all/gas.exp: Test will not pass on AVR due to linker
	relaxation support.
	* gas/avr/noreloc_withoutrelax.d: Add -mno-link-relax option.
	* gas/avr/link-relax-elf-flag-clear.d: Likewise.

ld/testsuite/ChangeLog:

	* ld/testsuite/ld-avr/relax-elf-flags-02.d: Add -mno-link-relax
	option.
	* ld/testsuite/ld-avr/relax-elf-flags-03.d: Likewise.
	* ld/testsuite/ld-avr/relax-elf-flags-04.d: Likewise.
	* ld/testsuite/ld-avr/relax-elf-flags-05.d: Likewise.
	* ld/testsuite/ld-avr/relax-elf-flags-06.d: Likewise.
AVR: Document linker relaxation related options.

Adds documentation describing the -mlink-relax and -mno-link-relax
command line options.

gas/ChangeLog:

	* doc/c-avr.texi: Document -mlink-relax and -mno-link-relax.
Add cast to unsigned long

	* pei-x86_64.c (pex64_bfd_print_pdata_section): Add cast to
	unsigned long.
Add lto and none-lto input support for ld -r

This patch adds lto and none-lto input support for ld -r so that
LTO can be used with ld -r without Makefile changes.  It is useful
for Linux kernel build with LTO.
Add test for nm on mixed LTO/non-LTO object
