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.

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.

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.

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,
alpha-linux, arm-linux, bfin-elf, cr16-elf, cris-elf, crx-elf, frv-linux,

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.

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.

Revert "bfd: allow negative offsets to _GLOBAL_OFFSET_TABLE_ in elf64 SPARC"
...
This reverts commit b19753ce31
.
As it turns out, GCC (and the assembler) needs additional work in
order to support negative GOT offsets in 64-bit sparc. This is
breaking TLS Local Dynamic in position-independent code.

Pass link_info to _bfd_merge_private_bfd_data

Most BFD linker functions take a bfd_link_info param, which reinforces
the fact that they are linker functions and allow access to linker

for --fatal-warnings support before I decided a better way was the
patch commit 4519d071

bfd: allow negative offsets to _GLOBAL_OFFSET_TABLE_ in elf64 SPARC
...
The code compiled with the -fpic model in SPARC uses 13-bit signed
immediate PC-relative loads to fetch entries from the GOT table. In
theory this would allow using a GOT table (.got section) containing up
to 1024 entries in elf32 or 512 entries in elf64.
However, in elf64 sparc GNU targets _GLOBAL_OFFSET_TABLE_ is always
placed at the beginning of the .got section, making it impossible to use
negative offsets. This limits the usage of -fpic to GOT tables
containing a maximum of 257 entries in elf64.
This patch activates an optimization that is already used in sparc-elf32
also in sparc-elf64, that sets _GLOBAL_OFFSET_TABLE_ to point 0x1000
into the .got section if the section size is bigger than 0x1000.

bfd,opcodes: sparc: new opcode v9{c,d,e,v,m} architectures and bfd machine numbers.
...
This patch adds support for the opcode architectures
SPARC_OPCODE_ARCH_V9{C,D,E,V,M} and its associated BFD machine numbers
bfd_mach_sparc_v9{c,d,e,v,m} and bfd_mach_sparc_v8plus{c,d,e,v,m}.
Note that for arches up to v9b (UltraSPARC III), the detection of the
BFD machine type was based on the bits in the e_machine field of the ELF
header. However, there are no more available bits in that field, so
this patch takes the approach of using the hardware capabilities stored
in the object attributes HWCAPS/HWCAPS2 in order to characterize the
machine the object was built for.

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".

Set dynamic tag VMA and size from dynamic section when possible
...
Rather than searching the output for a specific named section, it's
better, where possible, to use a linker created dynamic section to set
a dynamic tag's value. That way ld doesn't depend on the output
section name, making it possibile to map dynamic sections differently.

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.

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.

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.
