a0e90a73f0 [ARC] don't force _init/_fini as DT_INIT/DT_FINI.
Recent gcc commit b4371b277f1e ("[ARC] Enable init_array support")
inhibits DT_"INIT,FINI} in favor of DT_{INIT,FINI}ARRAY.

Even prior to that, it seems ARC port is the only one with this
special DT_INIT/FINI handling in linker emulation. Removing it
doesn't seem to change any uClibc/glibc testsuite results,
so this can RIP anyways.

This was always supposed to be an error.  Code emitted by gcc for
inline PLT calls assumes PLT is an array of addresses.

83924b3846 x86-64: Restore PIC check for PCREL reloc against protected symbol
commit bd7ab16b45
Author: H.J. Lu <hjl.tools@gmail.com>
Date:   Tue Feb 13 07:34:22 2018 -0800

    x86-64: Generate branch with PLT32 relocation

removed check R_X86_64_PC32 relocation against protected symbols in
shared objects.  Since elf_x86_64_check_relocs is called after we
have seen all input files, we can check for PC-relative relocations in
elf_x86_64_check_relocs.  We should not allow PC-relative relocations
against protected symbols since address of protected function and
location of protected data may not be in the shared object.

453f8e1e49 Fix GCC9 warning on elf32-arm.c:elf32_arm_final_link_relocate
Fedora Rawhide has just switched to GCC9, and now GDB doesn't compile
because of a BFD warning:

  BUILDSTDERR: ../../bfd/elf32-arm.c: In function 'elf32_arm_final_link_relocate':
  BUILDSTDERR: ../../bfd/elf32-arm.c:10907:10: error: absolute value function 'labs' given an argument of type 'bfd_signed_vma' {aka 'long long int'} but has parameter of type 'long int' which may cause truncation of value [-Werror=absolute-value]
  BUILDSTDERR: 10907 |  value = labs (relocation);
  BUILDSTDERR:       |          ^~~~

You can take a look at the full build log here:

  https://kojipkgs.fedoraproject.org//work/tasks/4828/32174828/build.log

The fix is (apparently) simple: instead of using 'labs', we should use
'llabs', since we're passing a 'bfd_signed_vma' to it, which is at
least a 'long long int', as far as I have checked.  This is what this
patch does.

bfd/ChangeLog:
2019-01-25  Sergio Durigan Junior  <sergiodj@redhat.com>

	* elf32-arm.c (elf32_arm_final_link_relocate): Use 'llabs' instead
	of 'labs' (and fix GCC warning).

0e41bebb93 PR24015, glibc-2.28 on little-endian mips32 broken
Commit 2bf2bf23da exposed a bug on targets that create common sections
other than the standard ELF SHN_COMMON.  If these are output by ld -r,
then their type becomes SHT_PROGBITS unless the target handles them
specially (eg. by elf_backend_special_sections), and if they are
merged into .bss/.sbss by ld -r then that section becomes SHT_PROGBITS.

Worse, if they are output by ld -r, then their size is increased by
bfd_generic_define_common_symbol during final link, which leads to
bogus file contents being copied to output.

For mips, it seems to me that the .scommon section should not be
output for ld -r, but I haven't made that change in this patch.

0a59decbb8 elf: Add PT_GNU_PROPERTY segment type
Linkers group input note sections with the same name into one output
note section with the same name.  One output note section is placed in
one PT_NOTE segment.  New linkers merge all input .note.gnu.property
sections into one output .note.gnu.property section with a single
NT_GNU_PROPERTY_TYPE_0 note in a single PT_NOTE segment.  Since older
linkers treat input .note.gnu.property section as a generic note section
and just concatenate all input .note.gnu.property sections into one
output .note.gnu.property section without merging them, we may
see one or more NT_GNU_PROPERTY_TYPE_0 notes in PT_NOTE segment, which
are invalid.

GNU_PROPERTY_X86_UINT32_VALID was defined to address this issue such
that linker sets the bit for non-relocatable outputs.  But it isn't
sufficient:

1. It doesn't cover generic properties.
2. When -mx86-used-note=yes is passed to x86 assembler, the
GNU_PROPERTY_X86_UINT32_VALID bit is set in GNU_PROPERTY_X86_ISA_1_USED
property in object file and older linkers generate invalid
NT_GNU_PROPERTY_TYPE_0 notes with the GNU_PROPERTY_X86_UINT32_VALID bit
set.

I am proposing the following changes:

1. Add PT_GNU_PROPERTY segment type:

 # define PT_GNU_PROPERTY (PT_LOOS + 0x474e553)

which covers .note.gnu.property section.
2. Remove GNU_PROPERTY_X86_UINT32_VALID.

bb6bf75e7a PowerPC @l, @h and @ha warnings, plus VLE e_li
This patch started off just adding the warnings in tc-ppc.c about
incorrect usage of @l, @h and @ha in instructions that don't have
16-bit D-form fields.  That unfortunately showed up three warnings in
ld/testsuite/ld-powerpc/vle-multiseg.s on instructions like
	e_li r3, IV_table@l+0x00
which was being assembled to
   8:	70 60 00 00 	e_li    r3,0
			a: R_PPC_ADDR16_LO	IV_table
The ADDR16_LO reloc is of course completely bogus on e_li, which has
a split 20-bit signed integer field in bits 0x1f7fff, the low 11 bit
in 0x7ff, the next 5 bits in 0x1f0000, and the high 4 bits in 0x7800.
Applying an ADDR16_LO reloc to the instruction potentially changes
the e_li instruction to e_add2i., e_add2is, e_cmp16i, e_mull2i,
e_cmpl16i, e_cmph16i, e_cmphl16i, e_or2i, e_and2i., e_or2is, e_lis,
e_and2is, or some invalid encodings.

Now there is a relocation that suits e_li, R_PPC_VLE_ADDR20, which was
added 2017-09-05 but I can't see code in gas to generate the
relocation.  In any case, VLE_ADDR20 probably doesn't have the correct
semantics for @l since ideally you'd want an @l to pair with @h or @ha
to generate a 32-bit constant.  Thus @l should only produce a 16-bit
value, I think.  So we need some more relocations to handle e_li it
seems, or as I do in this patch, modify the behaviour of existing
relocations when applied to e_li instructions.

3a67e1a6b4 [aarch64] Add support for pointer authentication B key
Armv8.3-A has another key used in pointer authentication called the
B-key (other than the A-key that is already supported). In order for
stack unwinders to work it is necessary to be able to identify frames
that have been signed with the B-key rather than the A-key and it was
felt that keeping this as an augmentation character in the CIE was the
best bet. The DWARF extensions for ARM therefore propose to add a new
augmentation character 'B' to the CIE augmentation string and the
corresponding cfi directive ".cfi_b_key_frame". I've made the relevant
changes to GAS and LD to add support for B-key unwinding, which required
modifying LD to check for 'B' in the augmentation string, adding the
".cfi_b_key_frame" directive to GAS and adding a "pauth_key" field to
GAS's fde_entry and cie_entry structs.

The pointer authentication instructions will behave as NOPs on
architectures that don't support them, and so a check for the
architecture being assembled for is not necessary since there will be no
behavioural difference between augmentation strings with and without the
'B' character on such architectures.

For GNU_PROPERTY_X86_COMPAT_ISA_1_USED and GNU_PROPERTY_X86_UINT32_OR_AND
properties, a bit in the output pr_data field is set if it is set in any
relocatable input pr_data fields and this property is present in all
relocatable input files.  A missing property implies that its bits have
unknown values.  When all bits in the the output pr_data field are zero,
this property should not be removed from output to indicate it has zero

b5ab31636d [ARM] Update knowledge of bfd architectures
Commit c0c468d562 updated bfd's knowledge
of Arm architectures to Armv5TEJ and later but missed the list of CPUs
recognized by objdump -d -m<cpu>.

.note.gnu.arm.ident related code is intentionally not updated as build
attributes are a better mechanism to express the ISA in a file. However
this patch adds tests for the existing code since no existing testcase
cover those codepaths. Since I've only ever managed for
bfd_arm_get_mach_from_notes () to have an effect by using objcopy on
a file with a note but no Arm build attribute, the tests make use of
both objcopy actions supported by run_dump_test which requires to have a
ld line as well.

Note that the CPU list in bfd/cpu-arm.c was simply copied over from
GAS' CPU list but sorted alphabetically as already done for existing
entries.

3c7687b9cd MIPS/LD: Accept high-part relocations in PIC code with absolute symbols
Accept R_MIPS_HI16, R_MIPS_HIGHER and R_MIPS_HIGHEST relocations and
their compressed counterparts in PIC code where the symbol referred is
absolute.  Such an operation is meaningful, because an absolute symbol
effectively is a constant the calculation of the value of which has been
deferred to the static link time, and which is not going to change any
further at the dynamic load time.  Therefore there is no need ever to
refuse the use of these relocations with such symbols, as the resulting
run-time value observed by the program will be correct even in PIC code.

This is not the case with R_MIPS_26 and its compressed counterparts,
because the run-time value calculated by the instructions these
relocations are used with depends on the address of the instruction
itself, and that can change according to the base address used by the
dynamic loader.  Therefore these relocations have to continue being
rejected in PIC code even with absolute symbols.

This allows successful linking of code that relies on previous linker
behavior up to commit 861fb55ab5 ("Defer allocation of R_MIPS_REL32
GOT slots"), <https://sourceware.org/ml/binutils/2008-08/msg00096.html>,
which introduced the problematic check missing this special exception

aff68bd041 MIPS/LD: Continue processing with refused relocations in PIC code
Switch from `_bfd_error_handler' to `info->callbacks->einfo' with error
reporting concerning the use of position-dependent relocations such as
R_MIPS_HI16 or R_MIPS_26 in PIC code and continue processing so that any
subsequent link errors are also shown rather than the linker terminating
right away.  This can reduce user frustration where correcting one error
only reveals another one; instead all are shown together making them all
possible to investigate at once.  The use of the `%X' specifier causes
the linker to terminate unsuccessfully at the end of processing.

Also fix the message to say `cannot' rather than `can not'.

9fca35fc34 AArch64: Fix regression in Cortex A53 erratum when PIE. (PR ld/23904)
The fix for PR ld/22263 causes TLS relocations using ADRP to be relaxed
into MOVZ, however this causes issues for the erratum code.

The erratum code scans the input sections looking for ADRP instructions
and notes their location in the stream.

It then later tries to find them again in order to generate the linker
stubs.  Due to the relaxation it instead finds a MOVZ and hard aborts.

Since this relaxation is a valid one, and in which case the erratum no
longer applies, it shouldn't abort but instead just continue.

This changes the TLS relaxation code such that when it finds an ADRP and
it relaxes it, it removes the erratum entry from the work list by changing
the stub type into none so the stub is ignored.

The entry is not actually removed as removal is a more expensive operation
and we have already allocated the memory anyway.

The clearing is done for IE->LE and GD->LE relaxations, and a testcase is
added for the IE case. The GD case I believe to be impossible to get together
with the erratum sequence due to the required BL which would break the sequence.
However to cover all basis I have added the guard there as well.

build on native hardware and regtested on
  aarch64-none-elf, aarch64-none-elf (32 bit host),

ca94519e70 Fix linking MSP430 files created by gcc's LTO optimizer.
When invoking GCC with "-g -flto", the compiler will create LTO objects
with debug information. The objects created are "simple ELF" objects (see
libiberty/simple-object-elf.c) and do not have target-specific sections.

When the MSP430 linker sees one of these objects without a .MSP430.attributes
section it errors:

> error: /tmp/cc4LhbEI.ltrans0.ltrans.o uses MSP430X instructions but /tmp/ccynqIwudebugobj uses unknown
> error: /tmp/cc4LhbEI.ltrans0.ltrans.o uses the small code model whereas /tmp/ccynqIwudebugobj uses the unknown code model
> error: /tmp/cc4LhbEI.ltrans0.ltrans.o uses the small data model whereas /tmp/ccynqIwudebugobj uses the unknown data model
> error: /tmp/cc4LhbEI.ltrans0.ltrans.o uses the small code model but /tmp/ccynqIwudebugobj uses the unknown data model
> failed to merge target specific data of file /tmp/cc4LhbEI.ltrans0.ltrans.o

The following patch allows these debug LTO objects to be linked with other
MSP430 objects even if they do not have a .MSP430.attributes section.

bfd	* elf32-msp430.c (elf32_msp430_merge_mspabi_attributes): Do not
	error when .MSP430.attributes section is missing from objects
	created by LTO.

strip/objcopy can't deal with alloc reloc sections, not .rela.dyn or

executable.  So, don't have BFD treat them as side-channel data
associated with the section they are relocating.

f32a4a5939 Don't create got section while processing TLS Local Exec relocations.
For Local Exec TLS model, the offset of the variable from the thread pointer
can be computed at static link time. This doesn't require GOT indirection.

The initial change is a bad fix for a problem during TLS GD -> LE relaxation.
The proper fix is to check whether _GLOBAL_OFFSET_TABLE_ is referenced,
create got section if yes.  And the fix is already in the repository.

2849d19feb S12Z: New 32 bit Reloc.
Third party tools produce 32 bit relocs  at index 6 with strange properties.
This change moves the existing 32 bit reloc (R_S12Z_EXT32) to index 7
and introduces a new one (R_S12Z_CW32) at index 6 to try to support code
generated by these tools.
