H.J. Lu df18fdba5d Properly display extra data/address size prefixes
X86 disassembler checks data and address size prefixes when displaying
instruction mnemonic and operands.  For the extra data and address size
prefixes, their names depend only on the address mode, not the data and
address size prefixes.  This patch changes x86 disassembler not to check
the data and address size prefix when printing extra data and address size
prefixes.

Kwok Cheung Yeung cb22ccf411 This patch causes local GOT entries addressed via a 16-bit index to
be placed towards the front of local GOT space, while entries addressed
via a 32-bit index are placed towards the rear.

a 16-bit index in total, this should eliminate any relocation overflows
caused by such GOT entries being allocated beyond the addressable range.

Marcus Shawcroft fa85fb9a1b [AArch64] Fix off by one error in instruction relaxation mask.
The AArch64 TLSDESC to IE relaxation code uses a bit mask intended to
ensure that destination register in a relaxed ldr instruction is
always X0.  The mask has an off by one error resulting in the most
significant bit of the destination register being retained in the
relaxed instruction.  The issue generally appears when the compiler
emits TLS accesses code under high register pressure resulting in a
broken code sequence.

Alan Modra b4ab436423 ppc476 icache workaround fix for bctr
I got the ppc476 workaround wrong.  bctr (and bctrl) as the last
instruction in a page can hit the icache bug if the preceding mtctr
insn is close by, and the destination is in the first few instructions
on the next page.  This scenario can occur with code generated by gcc
to implement switch statements, or in code generated to call by
function pointer.

To prevent the bctr problem it is also necessary to remove other
instructions that otherwise would be safe.

Cary Coutant abc9061b5c Document optional comma in linker script.
The linker script documentation does not mention the optional comma
that may follow an output section command or an overlay command.
In some cases, where a fill expression is used, and the next
output section command begins with an operator (e.g., "/DISCARD/"),
the comma may be required to separate the two commands.

Currently, GNU ld doesn't require the comma, but gold does.

Nick Clifton 76f0cad6f4 This is a fix for PR ld/16744 which showed that an object file linked with -r and -z [no]execstack
would not honour the [no]execstack.  Fully linked binaries use a special segment to indicate the
state of the stack, but relocatable object files only have sections, and .note.GNU-stack was not
being created.

Alan Modra f6c7c3e8b7 Referencing a function's address on PowerPC64 ELFv2
ELFv2 needs to create plt entries in a non-PIC executable for an
address reference to a function defined in a shared object.  It's
possible that an object file has no features that distinguish it as
ELFv1 or ELFv2, eg. an object only containing data.  Such files need
to be handled like those that are known to be ELFv2.
However, this unnecessarily creates plt entries for the analogous
ELFv1 case, so arrange to set output abi version earlier, and use the
output abi version to further distinguish ambiguous input files.

bfd/
	* elf64-ppc.c (ppc64_elf_check_relocs): Account for possibly
	needed plt entries when taking the address of functions for
	abiversion == 0 (ie. unknown) as well as abiversion == 2.
	Move opd setup and abiversion checks to..

Will Newton c955de363b bfd/elfnn-aarch64.c: Fix calculation of DT_RELASZ
The current code subtracts the size of the output section containing
relplt from RELASZ. In some cases this will be the same output
section as the dynamic relocs causing a value of zero to be output.
Calculating the size from input sections seems to make more sense.
