6f8b365b65 s390: Avoid reloc overflows on undefined weak symbols (cont) 
This complements and reuses logic from Andreas Krebbel's commit
896a639bab ("s390: Avoid reloc overflows on undefined weak symbols").

Replace relative long addressing instructions of weak symbols, which
will definitely resolve to zero, with either a load address of 0 or a
a trapping insn.

This prevents the PLT32DBL relocation from overflowing in case the
binary will be loaded at 4GB or more.

bfd/
	* elf64-s390.c (elf_s390_relocate_section): Replace
	instructions using undefined weak symbols with relative
	addressing to avoid relocation overflows.

ld/
	* testsuite/ld-s390/s390.exp: Add new test.
	* testsuite/ld-s390/weakundef-2.s: New test.

83511d2679 s390: Do not replace brcth referencing undefined weak symbol 
Branch Relative on Count High (brcth) is a conditional branch relative
instruction. It is not guaranteed that it only appears within loops
that sooner or later will take the branch. It may very well be used to
check a condition that will prevent the branch from ever being taken.

bfd/
	* elf64-s390.c (elf_s390_relocate_section): Do not replace brcth
	referencing undefined weak symbol with a trap.

48e63b8753 IBM zSystems: Rewrite l(g)rl @GOTENT to larl for --no-pie 
Regtested on s390x-redhat-linux.

Rewriting l(g)rl @GOTENT to larl is unnecessarily guarded by
bfd_link_pic().  There were no use cases for this in the past, but
since recently the Linux Kernel on s390x is compiled with -fPIE
and linked with --no-pie.  Remove the unnecessary bfd_link_pic()
check.

bfd/ChangeLog:

        * elf32-s390.c (elf_s390_relocate_section): Don't check for
	bfd_link_pic() when rewriting lrl@GOTENT to larl.
	(elf_s390_finish_dynamic_symbol): Emit a relative reloc for
	the above case.
        * elf64-s390.c (elf_s390_relocate_section): Don't check for
	bfd_link_pic() when rewriting lgrl@GOTENT to larl.
	(elf_s390_finish_dynamic_symbol): Emit a relative reloc for
	the above case.

fd67aa1129 Update year range in copyright notice of binutils files 
Adds two new external authors to etc/update-copyright.py to cover
bfd/ax_tls.m4, and adds gprofng to dirs handled automatically, then
updates copyright messages as follows:

1) Update cgen/utils.scm emitted copyrights.
2) Run "etc/update-copyright.py --this-year" with an extra external
   author I haven't committed, 'Kalray SA.', to cover gas testsuite
   files (which should have their copyright message removed).
3) Build with --enable-maintainer-mode --enable-cgen-maint=yes.
4) Check out */po/*.pot which we don't update frequently.

906f69cf65 IBM zSystems: Issue error for *DBL relocs on misaligned symbols 
Relocs like PC32DBL require a right shift of the symbol value.  There
is no situation where dropping symbol value bits with the right shift
is a good thing.  Hence we now issue an error to detect such problems.

2f83249c13 elf: Remove the 1-page gap before the RELRO segment 
The existing RELRO scheme may leave a 1-page gap before the RELRO segment
and align the end of the RELRO segment to the page size:

  [18] .eh_frame    PROGBITS    408fa0 008fa0 005e80 00   A  0   0  8
  [19] .init_array  INIT_ARRAY  410de0 00fde0 000008 08  WA  0   0  8
  [20] .fini_array  FINI_ARRAY  410de8 00fde8 000008 08  WA  0   0  8
  [21] .dynamic     DYNAMIC     410df0 00fdf0 000200 10  WA  7   0  8
  [22] .got         PROGBITS    410ff0 00fff0 000010 08  WA  0   0  8
  [23] .got.plt     PROGBITS    411000 010000 000048 08  WA  0   0  8

Instead, we can remove the 1-page gap if the maximum page size >= the
maximum section alignment:

  [18] .eh_frame    PROGBITS    408fa0 008fa0 005e80 00   A  0   0  8
  [19] .init_array  INIT_ARRAY  40fde0 00fde0 000008 08  WA  0   0  8
  [20] .fini_array  FINI_ARRAY  40fde8 00fde8 000008 08  WA  0   0  8
  [21] .dynamic     DYNAMIC     40fdf0 00fdf0 000200 10  WA  7   0  8
  [22] .got         PROGBITS    40fff0 00fff0 000010 08  WA  0   0  8
  [23] .got.plt     PROGBITS    410000 010000 000048 08  WA  0   0  8

Because the end of the RELRO segment is always aligned to the page size
and may not be moved, the RELRO segment size may be increased:

  [ 3] .dynstr      STRTAB      000148 000148 000001 00   A  0   0  1
  [ 4] .eh_frame    PROGBITS    000150 000150 000000 00   A  0   0  8
  [ 5] .init_array  INIT_ARRAY  200150 000150 000010 08  WA  0   0  1
  [ 6] .fini_array  FINI_ARRAY  200160 000160 000010 08  WA  0   0  1
  [ 7] .jcr         PROGBITS    200170 000170 000008 00  WA  0   0  1
  [ 8] .data.rel.ro PROGBITS    200180 000180 000020 00  WA  0   0 16
  [ 9] .dynamic     DYNAMIC     2001a0 0001a0 0001c0 10  WA  3   0  8
  [10] .got         PROGBITS    200360 000360 0002a8 00  WA  0   0  8
  [11] .bss         NOBITS      201000 000608 000840 00  WA  0   0  1

vs the old section layout:

  [ 3] .dynstr      STRTAB      000148 000148 000001 00   A  0   0  1
  [ 4] .eh_frame    PROGBITS    000150 000150 000000 00   A  0   0  8
  [ 5] .init_array  INIT_ARRAY  200b48 000b48 000010 08  WA  0   0  1
  [ 6] .fini_array  FINI_ARRAY  200b58 000b58 000010 08  WA  0   0  1
  [ 7] .jcr         PROGBITS    200b68 000b68 000008 00  WA  0   0  1
  [ 8] .data.rel.ro PROGBITS    200b70 000b70 000020 00  WA  0   0 16
  [ 9] .dynamic     DYNAMIC     200b90 000b90 0001c0 10  WA  3   0  8

  [11] .bss         NOBITS      201000 000ff8 000840 00  WA  0   0  1

b10b530a45 IBM Z: Add support for HLASM extended mnemonics 
Add extended mnemonics used in the HLASM assembler.  All of them are
just aliases for instructions we already support and help when
assembling code which was written for the HLASM assembler.

The HLASM mnemonics are documented here:
https://www.ibm.com/support/knowledgecenter/SSENW6_1.6.0/com.ibm.hlasm.v1r6.asm/asmr1023.pdf

See the 'Branching with extended mnemonic codes' chapter.

objdump will still print the existing mnemonics with the exception of
relative nop branches (i.e. conditional branches with an empty
condition code mask).  Now we have jnop and jgnop which will be used
by objdump when possible.

The same change have been applied to the LLVM assembler:
https://reviews.llvm.org/D92185

f26a32876b Dynamic TLS section symbols 
It is possible to create shared libraries on PowerPC using
-ftls-model=inital-exec or -ftls-model=local-exec.  The first is half
reasonable, getting you a shared library that can't be dlopen'd but
otherwise is reasonable.  The second is quite bad.  Not only do you
lose being able to dlopen, the library also has dynamic text
relocations.  Worse, the TPREL16_LO, TPREL16_HA and other TPREL16
dynamic relocs emitted were wrong, resulting in wrong values being
applied by ld.so.

Using the first TLS section symbol in dynamic relocations for local
TLS symbols doesn't work.  It's wrong because TLS symbols used by TLS
relocs have values relative to the TLS segment, whereas the TLS
section symbols are addresses.  This patch instead uses a symbol index
of zero which is used elsewhere by PowerPC on dynamic TLS relocs.
It's not strictly ABI compliant to use a non-TLS symbol with TLS
relocs but symbol index zero can be interpreted as "no symbol".  Not
using the first TLS section symbol means it doesn't need to be dynamic.

The patch also fixes a further problem with PowerPC32 dynamic TPREL16*
relocs, which shouldn't have the symbol value in the addend as we do
for non-TLS symbols.

e6213e09ed S/390: Prevent GOT access rewrite for certain symbols 
When dereferencing a GOT slot with lgrl or lg we rewrite this using
larl to get rid of the extra memory access.  However, we cannot do
this for:

- symbols marked for absolute addressing
- symbols at odd addresses (larl can handle only even addresses)

Fixed with the attached patch.

afca762f59 S/390: Improve partial relro support for 64 bit 
Currently on S/390 the .got.plt always comes first which prevents the
GNU_RELRO segment from being extended across the non-plt GOT entries.

Just swapping both unfortunately is not that simple since our ABI
requires the _GLOBAL_OFFSET_TABLE_ symbol to point to the very
beginning of the entire GOT. Of the 3 magic GOT entries the first is
accessed via got pointer while second and third are being accessed via
DT_PLTGOT.  In order to keep them together we make DT_PLTGOT to point
to the .got instead of .got.plt.  However, this violates an assumption
in the dynamic linker prelink undo code about the GOTPLT entries
starting at DT_PLTGOT + 3.  We got rid of this requirement with a
Glibc patch already in version 2.24:
https://sourceware.org/ml/libc-alpha/2016-06/msg01302.html

So the S/390 relro GOT layout will look like this with this patch:

      +----------------------------------+
      |got[0]: DYNAMIC                   |   <--- _GLOBAL_OFFSET_TABLE_ == DT_PLTGOT .got
      |got[1]: link_map parm             |
      |got[2]: &_dl_runtime_resolve      |
      +----------------------------------+
      |                                  |   non-plt GOT entries
      |                                  |
      |                                  |
      +----------------------------------+
      |                                  |   <--- .gotplt, PLT GOT entries
      |                                  |
      |                                  |
      |                                  |
      +----------------------------------+

The patch detects the current layout in size_dynamic_section in order
to deal also with linker scripts not generated by this ld version.
With partial relro enabled we pick a linker script where .got and
.got.plt are swapped which then triggers the rest of the logic.

fd161d860f Define various symbols conditionally in shared libraries 
The values of symbols in shared libraries like _end, _edata, and
__bss_start are generally not that useful outside of the shared
library.  This patch defines them conditionally with PROVIDE, since a
shared library might need the local value.  An example is glibc ld.so
local access to "_begin", "_etext" and "_end".  (ld.so gains access to
the local values by making the references using hidden visibility.
That makes the definitions hidden too.)

We can't use PROVIDE_HIDDEN in the linker scripts because the shared
library might need the value of the symbol in the executable.  An
example is freebsd libc dynamic access to "_end".

f882209d9a ld: Remove PF_X from PT_PHDR segment 
It was reasonable to mark PT_PHDR segment with PF_X for compatibility
with UnixWare and Solaris linkers 20 years ago.  But it is inappropriate
today when the primary OS of GNU ld is Linux.  This patch removes PF_X
from PT_PHDR segment as gold does.

Tested natively on Linux/x86 as well as crosss-binutils for alpha-linux,
ia64-linux, powerpc64-linux, powerpc-linux, s390-linux, s390x-linux,
sparc64-linux and sparc-linux.

	PT_PHDR segment.

d3a49aa80b readelf ngettext fixes 
This patch is a first pass at fixing readelf message pluralization.
I've deliberately not fixed the "out of memory" errors since it's very
unlikely that they will ever be complaining about not being able to
allocate for a single entry, and a few others where the size is very
unlikely to be 1 byte.

Then there are messages like this one:
"Out of %lu items there are %zu bucket clashes (longest of %zu entries).\n"
I suppose this could be split into three parts, "Of %lu items ",
"there are %zu bucket clashes ", and "(longest of %zu entries).\n",
each part being printed separately, but that might not be ideal for
sentence construction in other languages.  For now I'm punting on this
one.

Changes to readelf output require lots of testsuite adjustment..

bab55c0522 Support different ld --hash-style in the ld testsuite 
When ld is running with something other than --hash-style=sysv by
default, numerous tests need tweaking.  Most of the changes just add
--hash-style=sysv.  I didn't want to make --hash-style=sysv global as
that means --hash-style=gnu isn't well tested.

a24bb4f0cc Enhance objdump so that it will use .got, .plt and .plt.got section symbols when disassembling, and it will use dynamic relocs to interpret entries in the PLT and GOT. 
binutils * objdump.c (is_significant_symbol_name): New function.
	(remove_useless_symbols): Do not remove significanr symbols.
	(find_symbol_for_address): If an exact match for the specified
	address has not been found, try scanning the dynamic relocs to see
	if one of these matches the address.  If so, use the symbol
	associated with the reloc.
	(objdump_print_addr_with_symbol): Do not print offsets to symbols
	with no value.
	(disassemble_section): Only use dynamic relocs if the user
	requested this.
	(disassemble_data): Always load dynamic relocs if they are
	available.

82057c771e S/390: Move binary start to 16M. 
Turned out that by moving the binary start to 256M I've hit a case with
potentially a lot of aliasing in the branch target buffer between
binaries and shared libs.  So moving on.

Tested on s390x. No regressions.

963a4320b4 S/390: Fix gotreloc_31-1 testcase. 
Since we changed the default arch for objdump to zarch the following
testcase needs to check for the real instruction mnemonics instead of
just bytes.

This fixes the following testsuite fail on s390x:

2ec55de302 Properly place the NULL STT_FILE symbol revistited 
I was having a little closer look at what is going on here and noticed
that HJ unconditionally emits a NULL STT_FILE symbol before emitting
forced local symbols.  That means we really don't need a second pass
over forced local symbols.  The only reason for two passes is when
some forced local symbol can be emitted before the NULL STT_FILE.  So
I set about removing the second pass, updating the testsuite all over
again.  It's also unnecessary to emit the NULL STT_FILE when no
previous file symbol has been emitted.

	* elflink.c (struct elf_outext_info): Remove need_second_pass
	and second_pass.
	(elf_link_output_extsym): Delete code handling second forced

	that it can be omitted if forced local is stripped.  Don't
