a2c5833233 Update year range in copyright notice of binutils files 
The result of running etc/update-copyright.py --this-year, fixing all
the files whose mode is changed by the script, plus a build with
--enable-maintainer-mode --enable-cgen-maint=yes, then checking
out */po/*.pot which we don't update frequently.

The copy of cgen was with commit d1dd5fcc38ead reverted as that commit
breaks building of bfp opcodes files.

fd3619828e bfd_section_* macros 
This large patch removes the unnecessary bfd parameter from various
bfd section macros and functions.  The bfd is hardly ever used and if
needed for the bfd_set_section_* or bfd_rename_section functions can
be found via section->owner except for the com, und, abs, and ind
std_section special sections.  Those sections shouldn't be modified
anyway.

The patch also removes various bfd_get_section_<field> macros,
replacing their use with bfd_section_<field>, and adds
bfd_set_section_lma.  I've also fixed a minor bug in gas where
compressed section renaming was done directly rather than calling
bfd_rename_section.  This would have broken bfd_get_section_by_name
and similar functions, but that hardly mattered at such a late stage
in gas processing.

652afeef24 AArch64: Fix LD crash on weak and undefined TLS symbols. (PR/24602). 
This patch fixes a few linker crashes due to TLS code reaching an assert when it
shouldn't.

The first scenario is with weak TLS symbols that remain weak during linking.  In
this case the mid-end would not have seen a TLS symbol and so wouldn't have
allocated the TLS section.  We currently assert here and the linker crashes with
a not very useful message.

This patch changes this to return the value 0 for the TLS symbol in question
emulating what lld and gold and other BFD targets do.  However because weak TLS
is implementation defined and we don't define any behavior for it I also emit a
warning to the user to inform them of such.

Secondly when a strong TLS reference is undefined. The linker crashes even after
it correctly reported that there is an undefined reference.  This changes it so
that it gracefully exits and reports a useful error.

bfd/ChangeLog:

	PR ld/24601
	* elfnn-aarch64.c (aarch64_relocate): Handle weak TLS and undefined TLS.
	Also Pass input_bfd to _bfd_aarch64_elf_resolve_relocation.
	* elfxx-aarch64.c (_bfd_aarch64_elf_resolve_relocation): Use it.
	* elfxx-aarch64.h (_bfd_aarch64_elf_resolve_relocation): Emit warning
	for weak TLS.

ld/ChangeLog:

	PR ld/24601
	* testsuite/ld-aarch64/aarch64-elf.exp (undef-tls, weak-tls): New.
	* testsuite/ld-aarch64/undef-tls.d: New test.
	* testsuite/ld-aarch64/undef-tls.s: New test.
	* testsuite/ld-aarch64/weak-tls.d: New test.
	* testsuite/ld-aarch64/weak-tls.s: New test.

237df8fe18 [BFD, AArch64] Fix PT_GNU_PROPERTY alignment issue 
If the new GNU property section was being created by the linker
(this will happen only if none of the inputs have any GNU property
section but the command line to the linker forces a bti with
--force-bti), the alignment of the section and hence the program
header of PT_GNU_PROPERTY type was not being set correctly. This
patch fixes this issue.

4e5391148d [BFD, AArch64, x86] Improve warning for --force-bti 
The AArch64 linker option to turn on BTI (--force-bti) warns in case there are
input objects which have a missing GNU NOTE section for BTI. This patch is trying
to improve the warnings that come out.

In order to do so, I propose adding a new argument to elf_merge_gnu_properties
and the backend function merge_gnu_properties. This new argument makes sure
that we now pass both the objects along with the properties to which they
belong to. The x86 backend function has also been updated to match this
change.

cd702818c6 [BFD, LD, AArch64, 1/3] Add support for GNU PROPERTIES in AArch64 for BTI and PAC 
This is part of the patch series to add support for BTI and
PAC in AArch64 linker.

This patch implements the following:
1) This extends in the gnu property support in the linker for
AArch64 by defining backend hooks for elf_backend_setup_gnu_properties,
elf_backend_merge_gnu_properties and elf_backend_parse_gnu_properties.
2) It defines AArch64 specific GNU property
GNU_PROPERTY_AARCH64_FEATURE_1_AND and 2 bit for BTI and PAC in it.
3) It also adds support in readelf.c to read and print these new
GNU properties in AArch64.
All these are made according to the new AArch64 ELF ABI

2aff25ba76 [AArch64] Remove duplicated code when handling some GOT relocations types 
There are quite a few duplicated code supporting several GP based
relocation types.  They are:

  BFD_RELOC_AARCH64_LD64_GOTOFF_LO15
  BFD_RELOC_AARCH64_MOVW_GOTOFF_G0_NC
  BFD_RELOC_AARCH64_MOVW_GOTOFF_G1

These relocation types are supposed to be used for large memory model PIC/pic
mode under which we will have an initialized GP register points to the base of
GOT table, then these relocations are supposed to put the distance between GOT
entry and GOT table base address into the related instructions.

So, the parameters required to calculate the relocation should be the same as
BFD_RELOC_AARCH64_LD64_GOTPAGE_LO15 etc, all of them are require the GOT entry
address and GOT table base address to perform the relocation.

This patch has removed those duplicated code when handling above listed
relocation types,  grouped them with others as relocation types that are
require GOT table base address during performing relocation, reused the
existed GOT handling code.

The relocation calculation for these types before and after this patch should be
identical.

13a2df29c9 Set EI_OSABI to ELFOSABI_GNU for local IFUNC symbols 
Since the backend elf_add_symbol_hook isn't called on local symbols,
the EI_OSABI field isn't to ELFOSABI_GNU where are local IFUNC symbols.
This patch changes the x86 backends to set has_gnu_symbols if there are
relocations against IFUNC symbols.  Other backends with IFUNC support
may need a similar change.

This patch also changes the type of has_gnu_symbols from bfd_boolean to
enum elf_gnu_symbols.

4106101c44 [AArch64] Workaround for Cortex A53 erratum 843419 
Some early revisions of the Cortex-A53 have an erratum (843419).  The
details of the erratum are quite complex and involve dynamic
conditions.  For the purposes of the workaround we have simplified the
static conditions to an ADRP in the last two instructions of a 4KByte
page, followed within four instructions by a load/store dependent on
the ADRP.

This patch adds support to conservatively scan for and workaround
Cortex A53 erratum 843419.  There are two different workaround
strategies used.  The first is to rewrite ADRP instructions which form
part of an erratum sequence with an ADR instruction.  In situations
where the ADR provides insufficient offset the dependent load or store
instruction from the sequence is moved to a stub section and branches
are inserted from the original sequence to the relocated instruction
and back again.

Stub section sizes are rounded up to a multiple of 4096 in order to
ensure that the act of inserting work around stubs does not create
more errata sequences.

Workaround stubs are always inserted into the stub section associated
with the input section containing the erratum sequence.  This ensures
that the fully relocated form of the veneered load store instruction
is available at the point in time when the stub section is written.
