595d3787e9 Remove CR16C support 
I think it is past time to remove CR16C support.  CR16C was added in
2004, and only for ld.  gas and binutils support is lacking, and there
have been no commits to bfd/elf32-cr16c.c other than warning fixes or
global maintainers making changes to all targets.  I see no maintainer
listed for CR16C, and no commits from anyone at NSC supporting the
target.  Furthermore, at the time the CR16 support was added in 2007,
config.sub was changed upstream to no longer recognise cr16c as a
valid cpu.  That means the CR16C ld support is only available as a
secondary target by configuring with, for example,
--enable-targets=all or --enable-targets=cr16c-unknown-elf.  No
testing of the CR16C target is possible.

f2aaebdb97 GENERATE_SHLIB_SCRIPT vs. EMBEDDED. 
A target that sets EMBEDDED non-empty is one that doesn't want to put
the ELF file header or program header in a memory image.  Likely the
target isn't interested in supporting dynamically loaded executables,
shared libraries, or PIEs, because loaders for such binaries generally
require program headers to be present.  This isn't 100% true though.
The target might be one where the loader accesses the file system in
order to retrieve headers.

Also, note that not all "shared libraries" require gcc -shared or the
shared library support in the linker.  I believe one implementation of
shared libraries on uclinux is like this.

So, this patch removes GENERATE_SHLIB_SCRIPT and GENERATE_PIE_SCRIPT
in most emulparams files where EMBEDDED is set, restoring the shared
lib and pie support in emulparams files that unset EMBEDDED after
including a file where the support is removed.

Exceptions to the general rule that EMBEDDED disables shared libs are:
  arm*-*-symbianelf*, where the OS wants shared library support
  without ELF program headers in the image, and

  sh*-*-uclinux*, where I've left things as they were, ie. both
  EMBEDDED and GENERATE_SHLIB_SCRIPT because I'm unsure as to the
  shared library scheme.

22216541c1 PR13616, linker should pad executable sections with nops, not zeros 
This implements padding of orphan executable sections for PowerPC.
Of course, the simple implementation of bfd_arch_ppc_nop_fill and
removing the NOP definition didn't work, with powerpc64 hitting a
testsuite failure linking to S-records.  That's because the srec
target is BFD_ENDIAN_UNKNOWN so the test of bfd_big_endian (abfd) in
default_data_link_order therefore returned false, resulting in a
little-endian nop pattern.  The rest of the patch fixes that problem
by adding a new field to bfd_link_info that can be used to determine
actual endianness on targets like srec.

Mihailo Stojanovic
f16a9783c5 Add support for a MIPS specific .MIPS.xhash section. 
This patch is a reimplementation of [1] which was submitted in 2015 by
Neil Schellenberger. Copyright issue was sorted out [2] last year.
It proposed a new section (.gnu.xhash) and related dynamic tag
(DT_GNU_XHASH). The new section would be virtually identical to the
existing .gnu.hash except for the translation table (xlat) which would
contain correct MIPS .dynsym indexes corresponding to the hashvals in
chains. This is because MIPS ABI imposes a different ordering on the
dynsyms than the one expected by the .gnu.hash section. Another addition
would be a leading word (ngnusyms) which would contain the number of
entries in the translation table.

  In this patch, the new section name and dynamic tag are changed to
reflect the fact that the section should be treated as MIPS-specific
(.MIPS.xhash and DT_MIPS_XHASH).

  This patch addresses the alignment issue as reported in [3], which is
caused by the leading word added to the .MIPS.xhash section. Leading word
is removed in this patch, and the number of entries in the translation
table is now calculated using DT_MIPS_SYMTABNO dynamic tag (this is
addressed by the corresponding glibc patch).

  Suggestions on coding style in [4] were taken into account. Existing
GNU hash testcase was covered, and another one was added in the MIPS
part of the testsuite.

  The other major change is reserving MIPS ABI version 5 for .MIPS.xhash,
marking the need of support for .MIPS.xhash in the dynamic linker (again,
addressed in the corresponding glibc patch). This is something which I
am not sure of, especially after reading [5]. I am confused on whether
this ABI version is reserved for IFUNC, or it can be used for this
purpose.

Already mentioned glibc patch is submitted at:

fca8e23c31 ld: use a specific linker script in BPF targets 
This patch makes the elf64bpf emulation to use it's own linker script,
based on elf.sc.  At the moment, the only change is that the BPF
executable doesn't define an entry symbol (BPF programs feature
several entry points scattered in several sections.)

This is a step towards the goal of generating proper ELF executables
that would be loaded by the kernel's libbpf.  We are not there yet:
BPF "programs" should still be linked with -r.

This change removes a warning while linking executables, decreases the
number of unsupported tests in the target from 47 to 29, and increases
the number of expected passes from 104 to 145.

Regtested in x86_64 for all targets.
No regressions.

This changes s12z to use generic.em and genelf.em, which is more
suited to targets that use the generic linker hash table.  A tweak or
two to some testsuite predicates then gives a clean testsuite result
on the target.

c40e31a121 Automatic makefile dependencies for generated ld/e*.c 
This patch modifies genscripts.sh to emit dependency info along with
the generated emulation e*.c files.  This is done by a new source_sh
function that records its arg to a file (.deps/e*.Tc), using the
function whenever a shell script is sourced.  Entries in the file are
made unique and written to .deps/e*.Pc.  These files are then
included by the Makefile.

233a00833b x86: Add -z cet-report=[none|warning|error] 
Add -z cet-report=[none|warning|error] to report the missing Intel
Indirect Branch Tracking (IBT) and Shadow Stack (SHSTK) properties
in input .note.gnu.property section.  -z cet-report=none, which is
the default, will make the linker not report missing properties in
input files.  -z cet-report=warning will make the linker issue a
warning for missing properties in input files.  -z cet-report=error
will make the linker issue an error for missing properties in input
files.  Note that -z ibt will turn off the missing IBT property report
and -z shstk will turn off the missing SHSTK property report.

c55b17b809 Fix some ld dependencies 
In looking at the csky-elf vs. csky-linux differences, the first thing
I compared was csky_elf.sh and cskyelf_linux.sh.  Those files are
mostly the same but besides the real differences, annoyingly have some
lines ordered differently.  It's better in such cases to have one file
source the other, making differences plain.  This patch does that for
csky and microblaze, removes an unused variable defined in a few
places, and fixes ld makefile dependencies.

	* Makefile.am (eskyelf.c, eskyelf_linux.c): Depend on cskyelf.em.

2bf2bf23da ELF ld -r scripts 
"ld -r" generally should not combine object file sections with
different names.  For example, "ld -r" should not combine ".text",
".text.hot" and ".text.cold" into an output ".text" section.  An
exception needs to be made for linker created sections, for example,
branch trampoline sections that might be created even for ld -r.

"ld -r" also should not define symbols in linker scripts.  Any
definitions are likely to conflict with those defined at final link.

A MEMORY spec is also not needed for ld -r.

b8891f8d62 Add support for the C_SKY series of processors. 
This patch series is a new binutils port for C-SKY processors, including support for both the V1 and V2 processor variants.  V1 is derived from the MCore architecture while V2 is substantially different, with mixed 16- and 32-bit instructions, a larger register set, a different (but overlapping) ABI, etc.  There is support for bare-metal ELF targets and Linux with both glibc and uClibc.

This code is being contributed jointly by C-SKY Microsystems and Mentor Graphics.  C-SKY is responsible for the technical content and has proposed Lifang Xia and Yunhai Shang as port maintainers.  (Note that C-SKY does have a corporate copyright assignment on file with the FSF.) Mentor Graphics' role has been cleaning up the code, adding documentation and additional test cases, etc, to address issues we anticipated reviewers would complain about.

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.

1594e052d4 xgate cleanup 
elf32-xgate.c contains many functions that are only stubs and
elf32-xgate.h contains unused declarations.  While this might be
reasonable for the initial commit of a port with subsequent work
fleshing out the stubs, xgate has only had two minor target specific
patches since the initial commit over six years ago.  The rest of the
changes have been general maintenance work applied to all ELF targets,
and some of this work could have been avoided if the stubs hadn't been
there.  So this patch removes all the stubs.

I've kept the functionality of the old elf32_xgate_add_symbol_hook,
implemented in elf32_xgate_backend_symbol_processing.  Presumably,
that's to set the symbol st_target_internal flag for use in
elf32-m68hc1x.c:elf32_m68hc11_relocate_section.

The empty elf32_xgate_relocate_section meant that xgate had no linker.
Or at least, no linker relocation processing.  Deleting the
elf_backend_relocate_section define means the target will now use the
generic linker reloc processing.  How good that is will depend on the
accuracy of the reloc howtos..

I haven't updated the ld testsuite to xfail tests expected to fail
for generic elf targets.

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".

527278f336 TIC6X __c6xabi_DSBT_BASE 
Adding an undefined __c6xabi_DSBT_BASE via an EXTERN in the linker
script isn't ideal, as the symbol is not always needed.  This patch
adds the undefined symbol on encountering relocations where it is
implicitly referenced.

bfd/
	* elf32-tic6x.c (elf32_tic6x_check_relocs): Reference
	__c6xabi_DSBT_BASE explicitly for R_C6000_SBR_* relocs.
ld/
	* emulparams/elf32_tic6x_le.sh (EXECUTABLE_SYMBOLS): Don't define.
