14b57c7c6a PowerPC VLE
VLE is an encoding, not a particular processor architecture, so it
isn't really proper to select insns based on PPC_OPCODE_VLE.  For
example
{"evaddw",  VX (4, 512), VX_MASK, PPCSPE|PPCVLE, PPCNONE, {RS, RA, RB}},
{"vaddubs", VX (4, 512), VX_MASK, PPCVEC|PPCVLE, PPCNONE, {VD, VA, VB}},
shows two insns that have the same encoding, both available with VLE.
Enabling both with VLE means we can't disassemble the second variant
even if -Maltivec is given rather than -Mspe.  Also, we don't check
user assembly against the processor type as well as we could.

Another problem is that when using the VLE encoding, insns from the
main ppc opcode table are not available, except those using opcode 4
and 31.  Correcting this revealed two errors in the ld testsuite,
use of "nop" and "rfmci" when -mvle.

This patch fixes those problems in the opcode table, and removes
PPCNONE.  I find a plain 0 distracts less from other values.

In addition, I've implemented code to recognize some machine values
from the apuinfo note present in ppc32 objects.  It's not a complete
disambiguation since we're lacking info to detect newer chips, but
what we have should help with disassembly.

1f56df9d0d [AArch64] Also puts value in place for R_AARCH64_RELATIVE
When handling absolute relocations for global symbols bind within the
shared object, AArch64 will generate one dynamic RELATIVE relocation,
but won't apply the value for this absolution relocations at static
linking stage. This is different from AArch64 gold linker and x86-64.

This is not a bug as AArch64 is RELA, there is only guarantee that
relocation addend is placed in the relocation entry.  But some
system softwares originally writen for x86-64 might assume AArch64
bfd linker gets the same behavior as x86-64, then they could take
advantage of this buy skipping those RELATIVE dynamic relocations
if the load address is the same as the static linking address.

This patch makes AArch64 BFD linker applies absolution relocations at
static linking stage for scenario described above.  Meanwhile old AArch64
android loader has a bug (PR19163) which relies on current linker behavior
as a workaround, so the same option --no-apply-dynamic-relocs added.

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.

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.
	* reloc.c (bfd_perform_relocation): Correct bfd_reloc_outofrange check.
	(bfd_install_relocation, _bfd_final_link_relocate): Add same check here.
	* elf32-sh.c (sh_elf_reloc): Correct bfd_reloc_outofrange check.
	* elf32-ppc.c (ppc_elf_addr16_ha_reloc): Remove duplicated
	bfd_reloc_outofrange check.
	* bfd-in2.h: Regenerate.

	* cpu-ns32k.c (_bfd_do_ns32k_reloc_contents): Return bfd_reloc_ok
	on zero size relocs.
	* ecoff.c (ecoff_reloc_link_order): Likewise.

5979d6b69b Handle VDSO section headers past end of page
When a VDSO gets large enough that it doesn't entirely fit in one page,
but not so large that the part described by the program header exceeds
one page, then gdb/BFD doesn't read the section headers and symbol
table information.  This patch cures that by passing the size of the
vdso to BFD, and fixes a number of other issues in the BFD code.

	headers.  Handle zero p_align throughout.  Default loadbase to
