07d6d2b834 BFD whitespace fixes
Binutils is supposed to use tabs.  In my git config I have
whitespace = indent-with-non-tab,space-before-tab,trailing-space
and I got annoyed enough seeing red in "git diff" output to fix
the problems.

3bf083ed23 dyn_relocs tidy
Many targets define their own dyn_relocs struct when they could use
struct elf_dyn_relocs.  This patch tidies that, and uses
readonly_dynrelocs in a few more places.

The SH adjust_dynamic_symbol had some really weird code dating back to
2002 that looked over dynamic relocations for any in SEC_HAS_CONTENTS
or SEC_READONLY sections, rather than just the usual SEC_READONLY
sections.  So basically any dynamic relocation.  What's more, the SH
relocate_section has no support for emitting dynamic relocations in
non-PIC.  In other words, SH has no support for avoiding copy relocs
in non-PIC.  I've made that more obvious by using "if (0 && ..)" in
asjust_dynamic_symbol.

Unfortunately, LM32, M32R, NDS32, and OR1K copied the bogus SH
adjust_dynamic_symbol code.  So none of those targets would have
avoided copy relocs.  LM32, M32R, NDS32 get the "if (0)" treatment
too.  (LM32 is even more broken in that non_got_ref is never set.)

OR1K relocate_section looks like it might support dynamic relocs in
non-PIC, so I've enabled the copy reloc avoidance code for that
target.

63c1f59d66 readonly_dynrelocs
In early October, HJ Lu added support for a number of targets to "Dump
dynamic relocation in read-only section with minfo".  This extends
that support to more targets, displays the symbol involved, and splits
the existing function that sets TEXTREL into a "readonly_dynrelocs"
and "maybe_set_textrel" function.  I'll need "readonly_dynrelocs" if I
ever get around to fixing "pr22374 function pointer initialization"
fails.

am33_2.0, arc, bfin, hppa64, mn10300, and nios2 fail to mark a binary
needing text relocations with DT_TEXTREL.  That's not good.  xtensa also
fails to do so but complains about "dangerous relocation: dynamic
relocation in read-only section" so I reckon that is fine and have
marked the test as an xfail.  The other targets need maintainer
attention.

Curiously, the map file dump wasn't added for x86, so the map test
currently fail on x86.  It also fails on alpha, am33_2.0, arc, bfin,
hppa64, ia64, m68k, mips, mn10300, nios2, score and vax.  cris
complains with "tmpdir/textrel.o, section .rodata: relocation
R_CRIS_32 should not be used in a shared object; recompile with -fPIC"
so I've marked it as an xfail.

60d67dc84b Rename u.weakdef and make it a circular list
This makes the elf_link_hash_entry weakdef field, currently used to
point from a weak symbol to a strong alias, a circular list so that
all aliases can be found from any of them.  A new flag, is_weakalias,
distinguishes the weak symbol from a strong alias, and is used in all
places where we currently test u.weakdef != NULL.

With the original u.weakdef handling it was possible to have two or
more weak symbols pointing via u.weakdef to a strong definition.
Obviously that situation can't map to a circular list; One or more of
the weak symbols must point at another weak alias rather than the
strong definition.  To handle that, I've added an accessor function to
return the strong definition.

	Rename u.weakdef to u.alias and update comment.

	u.alias.  Update comments.

	u.weakdef != NULL and use weakdef function.

5c3261b0e8 ELF: Call check_relocs after opening all inputs
For all ELF targers, call check_relocs after opening all inputs and
garbage collection.  Since the symbol resolution is known, check_relocs
can be simplified.  Also garbage collection doesn't need to undo what
check_relocs has done for symbols which have been garbage collected.
Since ELF targets never see the removed sections, gc_sweep_hook can be
removed from elf_backend_data and we can avoid GOT/PLT with garbage
collection now.

Set link_info.check_relocs_after_open_input to TRUE for all linker
targets which use ELF linker and update garbage collection tests to
remove unused GOT section.

ldemul_after_check_relocs is added for powerpc to support --secure-plt,
--bss-plt and --sdata-got.

Tested natively without regressions on i686, x86-64 and x32.  Tested
cross binutils on x86-64 without regressions for aarch64-linux,

afbf7e8e3a Don't make dynamic .data.rel.ro SEC_READONLY
I'd made this dynamic section read-only so a flag test distinguished
it from .dynbss, but like any other .data.rel.ro section it really
should be marked read-write.  (It is read-only after relocation, not
before.)  When using the standard linker scripts this usually doesn't
matter since the output section is among other read-write sections and
not page aligned.  However, it might matter in the extraordinary case
of the dynamic section being the only .data.rel.ro section with the
output section just happening to be page aligned and a multiple of a
page in size.  In that case the output section would be read-only, and
live it its own read-only PT_LOAD segment, which is incorrect.

5474d94f03 dynrelro section for read-only dynamic symbols copied into executable
Variables defined in shared libraries are copied into an executable's
.bss section when code in the executable is non-PIC and thus would
require dynamic text relocations to access the variable directly in
the shared library.  Recent x86 toolchains also copy variables into
the executable to gain a small speed improvement.

The problem is that if the variable was originally read-only, the copy
in .bss is writable, potentially opening a security hole.  This patch
cures that problem by putting the copy in a section that becomes
read-only after ld.so relocation, provided -z relro is in force.

The patch also fixes a microblaze linker segfault on attempting to
use dynamic bss variables.

ce558b89b1 Delete duplicate target short-cuts to dynamic sections
We'd like to have the elf_link_hash_table srelplt field rather than
some private target field used to save short-cuts to a PLT relocation
section.  This save a little space but mainly is so that the generic
ELF code can access the field.  Ditto for other dynamic sections.

1a72702bb3 Return void from linker callbacks
The ldmain.c implementation of these linker callback functions always
return true, so any code handling a false return is dead.  What's
more, some of the bfd backends abort if ever a false return is seen,
and there seems to be some confusion in gdb's compile-object-load.c.
The return value was never meant to be "oh yes, a multiple_definition
error occurred", but rather "out of memory or other catastrophic
failure".

This patch removes the status return on the callbacks that always
return true.  I kept the return status for "notice" because that one
does happen to need to return "out of memory".

4ade44b727 Set dynamic tag VMA and size from dynamic section when possible
Rather than searching the output for a specific named section, it's

section name, making it possibile to map dynamic sections differently.

0e1862bb40 Add output_type to bfd_link_info
The "shared" field in bfd_link_info is set for both DSO and and PIE.
There are separate fields for executable and relocatable outputs.  This
patch adds an "output_type" field:

enum output_type
{
  type_unknown = 0,
  type_executable,
  type_dll,
  type_relocatable
};

and a "pic" field to bfd_link_info to replace shared, executable and
relocatable fields so that we can use the "output_type" field to check
for output type and the "pic" field check if output is PIC.  Macros,
bfd_link_executable, bfd_link_dll, bfd_link_relocatable, bfd_link_pic
and bfd_link_pie, are provided to check for output features.

6346d5ca43 Fallout from recent bfd_reloc_outofrange changes
Commit ec93045b and cd21f5da introduced a large number of tic4x and
tic54x regressions, due to the new checks being wrong for targets
with octets_per_byte != 1.  To fix that I introduced a new
bfd_get_section_limit_octets and performed the check on octets rather
than byte adresses, reducing the number of bfd_octets_per_byte calls.
bfd_octets_per_byte is rather expensive..

I then wondered why the same bfd_reloc_outofrange check added to
bfd_perform_relocation wasn't also added to bfd_install_relocation.
The two functions are virtually identical and ought to remain that
way.  However, adding the same check to bfd_install_relocation
resulted in ld-elf "FAIL Link eh-group.o to eh-group" on many ELF
targets, including x64_64-linux.  The reason being that eh-group.o
has NONE relocs at the end of a section, and most targets give NONE
relocs a non-zero size.  So if we are to keep the new outofrange
check it appears that NONE relocs must have a zero size.

	* bfd-in.h (bfd_get_section_limit_octets): New define, extracted from..
	(bfd_get_section_limit): ..here.

6cabe1ea46 Copy relocations against protected symbols
Copy relocs are used in a scheme to avoid dynamic text relocations in
non-PIC executables that refer to variables defined in shared
libraries.  The idea is to have the linker define any such variable in
the executable, with a copy reloc copying the initial value, then have
both the executable and shared library refer to the executable copy.
If the shared library defines the variable as protected then we have
two copies of the variable being used.

caa4096e84 Don't call bfd_link_hash_table_free
Freeing the linker hash table is a royal pain.  It can't be freed
before the _bfd_write_contents call in bfd_close, because some target
bfd_write_contents functions access the hash table.  It can't be freed
after bfd_close either, since bfd_alloc memory holding side data
structures disappears (PR17047).  Clearly the only place it can be freed
is actually in bfd_close.  This patch doesn't do that, but kills off
the existing means of freeing the hash table via a bfd target xvec call.
