4a9699735b PowerPC64 higher REL16 relocations 
There are occasions where someone might want to build a 64-bit
pc-relative offset from 16-bit pieces.  This adds the necessary REL16
relocs corresponding to existing ADDR16 relocs that can be used to
build 64-bit absolute values.

include/
	* elf/ppc64.h (R_PPC64_REL16_HIGH, R_PPC64_REL16_HIGHA),
	(R_PPC64_REL16_HIGHER, R_PPC64_REL16_HIGHERA),
	(R_PPC64_REL16_HIGHEST, R_PPC64_REL16_HIGHESTA): Define.
	(R_PPC64_LO_DS_OPT, R_PPC64_16DX_HA): Bump value.
bfd/
	* reloc.c (BFD_RELOC_PPC64_REL16_HIGH, BFD_RELOC_PPC64_REL16_HIGHA),
	(BFD_RELOC_PPC64_REL16_HIGHER, BFD_RELOC_PPC64_REL16_HIGHERA),
	(BFD_RELOC_PPC64_REL16_HIGHEST, BFD_RELOC_PPC64_REL16_HIGHESTA):
	Define.
	* elf64-ppc.c (ppc64_elf_howto_raw): Add new REL16 howtos.
	(ppc64_elf_reloc_type_lookup): Translate new REL16 relocs.
	(ppc64_elf_check_relocs, ppc64_elf_relocate_section): Handle them.
	* bfd-in2.h: Regenerate.
	* libbfd.h: Regenerate.
gas/
	* config/tc-ppc.h (TC_FORCE_RELOCATION_SUB_LOCAL): Allow ADDR16
	HIGH, HIGHA, HIGHER, HIGHERA, HIGHEST, and HIGHESTA relocs.
	Group 16-bit relocs.
	* config/tc-ppc.c (md_apply_fix): Translate those ADDR16 relocs
	to REL16 when pcrel.  Sort relocs.

a9eafb08b3 x86: Update GNU_PROPERTY_X86_XXX macros 
This patch updates GNU_PROPERTY_X86_XXX macros:

1. GNU_PROPERTY_X86_UINT32_AND_XXX: A 4-byte unsigned integer property.
A bit is set if it is set in all relocatable inputs:

 #define GNU_PROPERTY_X86_UINT32_AND_LO      0xc0000002
 #define GNU_PROPERTY_X86_UINT32_AND_HI      0xc0007fff

2. GNU_PROPERTY_X86_UINT32_OR_XXX: A 4-byte unsigned integer property.
A bit is set if it is set in any relocatable inputs:

 #define GNU_PROPERTY_X86_UINT32_OR_LO    0xc0008000
 #define GNU_PROPERTY_X86_UINT32_OR_HI    0xc000ffff

3. GNU_PROPERTY_X86_UINT32_OR_AND_XXX: A 4-byte unsigned integer property.
A bit is set if it is set in any relocatable inputs and the property is
present in all relocatable inputs:

 #define GNU_PROPERTY_X86_UINT32_OR_AND_LO   0xc0010000
 #define GNU_PROPERTY_X86_UINT32_OR_AND_HI   0xc0017fff

4. GNU_PROPERTY_X86_FEATURE_2_NEEDED, GNU_PROPERTY_X86_FEATURE_2_USED
and GNU_PROPERTY_X86_FEATURE_2_XXX bits.

GNU_PROPERTY_X86_FEATURE_1_AND is unchanged.  GNU_PROPERTY_X86_ISA_1_USED
and GNU_PROPERTY_X86_ISA_1_NEEDED are updated to better support targeted
processors since GNU_PROPERTY_X86_ISA_1_?86 aren't isn't very useful.
A new set of GNU_PROPERTY_X86_ISA_1_XXX bits are defined.  The previous
GNU_PROPERTY_X86_ISA_1_XXX macros are deprecated and renamed to
GNU_PROPERTY_X86_COMPAT_ISA_1_XXX.

	X86_UINT32_OR_AND_LO and X86_UINT32_OR_AND_HI instead of

aa7bca9b2e x86: Add GNU_PROPERTY_X86_UINT32_VALID 
The older linker treats .note.gnu.property section as a generic note
and just concatenates all .note.gnu.property sections from the input
to the output.  On CET-enabled OS, the output of the older linker is
marked as CET enabled, but in fact, it is not CET enabled and it crashes
on CET-enabled machines.

This patch defines GNU_PROPERTY_X86_UINT32_VALID.  Linker is updated to
set the GNU_PROPERTY_X86_UINT32_VALID bit in GNU property note for
non-relocatable output to differentiate outputs from the older linker.

9cf7e5687f Use operand->extract to provide defaults for optional PowerPC operands 
Most optional operands to powerpc instructions use a default value of
zero, but there are a few exceptions.  Those have been handled by
PPC_OPERAND_OPTIONAL_VALUE and an entry in the powerpc_operands table
for the default value, smuggled in the shift field.  This patch
changes that to using the operand extract function to provide non-zero
defaults.

I've also moved the code determining whether optional operands are
provided or omitted, to the point the first optional operand is seen,
and allowed for the possibility of optional base register operands
in a future patch.

The patch does change the error you get on invalid assembly like

  ld 3,4

You'll now see "missing operand" rather than
"syntax error; end of line, expected `('".

	* config/tc-ppc.c (md_assemble): Delay counting of optional

57285adece arm - Add some comments about the versions of ARM ELF that define various e_flags values 
This patch adds a few comments to include/elf/arm.h to clarify which
versions of the ARM ELF specification defined which headers.  Given
that the EABI is pretty ubiquitous these days, I've marked anything
not based on that as deprecated.

There are no plans to remove any deprecated definitions at this time,
but any new development shouldn't be building upon support for
deprecated definitions remaining in the long term.

b8891f8d62 Add support for the C_SKY series of processors. 
This patch series is a new binutils port for C-SKY processors, including support for both the V1 and V2 processor variants.  V1 is derived from the MCore architecture while V2 is substantially different, with mixed 16- and 32-bit instructions, a larger register set, a different (but overlapping) ABI, etc.  There is support for bare-metal ELF targets and Linux with both glibc and uClibc.

This code is being contributed jointly by C-SKY Microsystems and Mentor Graphics.  C-SKY is responsible for the technical content and has proposed Lifang Xia and Yunhai Shang as port maintainers.  (Note that C-SKY does have a corporate copyright assignment on file with the FSF.) Mentor Graphics' role has been cleaning up the code, adding documentation and additional test cases, etc, to address issues we anticipated reviewers would complain about.

fa758a7046 PowerPC Improve support for Gekko & Broadway 
This is a relatively straightforward patch to improve support for the
IBM Gekko and IBM Broadway processors.  Broadway is functionally
equivalent to the IBM 750CL, while Gekko's functionality is a subset
of theirs.  The patch simplifies this reality and adds -mgekko and
-mbroadway as aliases for -m750cl.  I didn't feel it was worth wasting
a PPC_OPCODE_* bit to differentiate Gekko.  The patch adds a number of
simplified mnemonics for special purpose register access.  Notably,
Broadway adds 4 additional IBAT and DBAT registers but these are not
assigned sequential SPR numbers.

d5c928c053 LD: Export relative-from-absolute symbol marking to BFD 
It is usually possible to tell absolute and ordinary symbols apart in
BFD throughout the link, by checking whether the section that owns the
symbol is absolute or not.

That however does not work for ordinary symbols defined in a linker
script outside an output section statement.  Initially such symbols are
entered into to the link hash as absolute symbols, owned by the absolute
section.  A flag is set in the internal linker expression defining such
symbols to tell the linker to convert them to section-relative ones in
the final phase of the link.  That flag is however not accessible to BFD
linker code, including BFD target code in particular.

Add a flag to the link hash then to copy the information held in the
linker expression.  Define a macro, `bfd_is_abs_symbol', for BFD code to
use where determining whether a symbol is absolute or ordinary is
required before the final link phase.

This macro will correctly identify the special `__ehdr_start' symbol as
ordinary throughout link, for example, even though early on it will be
assigned to the absolute section.  Of course this does not let BFD code
identify what the symbol's ultimate section will be before the final
link phase has converted this symbol (in `update_definedness').

471b9d1507 GDB PR tdep/8282: MIPS: Wire in `set disassembler-options' 
Implement MIPS target support for passing options to the disassembler,
complementing commit 65b48a8140 ("GDB: Add support for the new
set/show disassembler-options commands.").

This includes options that expect an argument, so adjust the generic
code and data structures used so as to handle such options.  So as to
give backends syntax flexibility no specific delimiter has been defined
to separate options from their respective arguments, so it has to be
included as the last character of the option name.  Completion code
however has not been adjusted and consequently option arguments cannot
be completed at this time.

Also the MIPS target has non-empty defaults for the options, so that ABI
names for the general-purpose registers respect our `set mips abi ...'
setting rather than always being determined from the ELF headers of the
binary file selected.  Handle these defaults as implicit options, never
shown to the user and always prepended to the user-specified options, so
that the latters can override the defaults.

The resulting output for the MIPS target is as follows:

(gdb) show disassembler-options
The current disassembler options are ''

The following disassembler options are supported for use with the
'set disassembler-options <option>[,<option>...]' command:

  no-aliases      Use canonical instruction forms.

  msa             Recognize MSA instructions.

  virt            Recognize the virtualization ASE instructions.

  xpa             Recognize the eXtended Physical Address (XPA) ASE
                  instructions.

  ginv            Recognize the Global INValidate (GINV) ASE instructions.

  gpr-names=ABI   Print GPR names according to specified ABI.
                  Default: based on binary being disassembled.

  fpr-names=ABI   Print FPR names according to specified ABI.
                  Default: numeric.

  cp0-names=ARCH  Print CP0 register names according to specified architecture.
                  Default: based on binary being disassembled.

  hwr-names=ARCH  Print HWR names according to specified architecture.
                  Default: based on binary being disassembled.

  reg-names=ABI   Print GPR and FPR names according to specified ABI.

  reg-names=ARCH  Print CP0 register and HWR names according to specified
                  architecture.

  For the options above, the following values are supported for "ABI":
    numeric 32 n32 64

  For the options above, the following values are supported for "ARCH":
    numeric r3000 r3900 r4000 r4010 vr4100 vr4111 vr4120 r4300 r4400 r4600
    r4650 r5000 vr5400 vr5500 r5900 r6000 rm7000 rm9000 r8000 r10000 r12000
    r14000 r16000 mips5 mips32 mips32r2 mips32r3 mips32r5 mips32r6 mips64
    mips64r2 mips64r3 mips64r5 mips64r6 interaptiv-mr2 sb1 loongson2e
    loongson2f loongson3a octeon octeon+ octeon2 octeon3 xlr xlp
(gdb)

which corresponds to what `objdump --help' used to print for the MIPS
target, with minor formatting changes, most notably option argument
lists being wrapped, but also the amount of white space separating
options from the respective descriptions.  The relevant part the new
code is now also used by `objdump --help', which means these formatting
changes apply to both outputs, except for argument list wrapping, which
is GDB-specific.

This also adds a separating new line between the heading and option
lists where descriptions are provided, hence:

(gdb) set architecture s390:31-bit
(gdb) show disassembler-options
The current disassembler options are ''

The following disassembler options are supported for use with the
'set disassembler-options <option>[,<option>...]' command:

  esa         Disassemble in ESA architecture mode
  zarch       Disassemble in z/Architecture mode
  insnlength  Print unknown instructions according to length from first two bits
(gdb)

but:

(gdb) set architecture powerpc:common
(gdb) show disassembler-options
The current disassembler options are ''

The following disassembler options are supported for use with the
'set disassembler-options <option>[,<option>...]' command:
  403, 405, 440, 464, 476, 601, 603, 604, 620, 7400, 7410, 7450, 7455, 750cl,
  821, 850, 860, a2, altivec, any, booke, booke32, cell, com, e200z4, e300,
  e500, e500mc, e500mc64, e5500, e6500, e500x2, efs, efs2, power4, power5,
  power6, power7, power8, power9, ppc, ppc32, 32, ppc64, 64, ppc64bridge,
  ppcps, pwr, pwr2, pwr4, pwr5, pwr5x, pwr6, pwr7, pwr8, pwr9, pwrx, raw, spe,
  spe2, titan, vle, vsx
(gdb)

Existing affected target backends have been adjusted accordingly.

This has been verified manually with:

(gdb) set architecture arm
(gdb) set architecture powerpc:common
(gdb) set architecture s390:31-bit

to cause no issues with the `show disassembler-options' and `set
disassembler-options' commands.  A test case for the MIPS target has
also been provided, covering the default settings with ABI overrides as
well as disassembler option overrides.

369c9167d4 Fix AArch64 encodings for by element instructions. 
Some instructions in Armv8-a place a limitation on FP16 registers that can be
used as the register from which to select an element from.

e.g. fmla restricts Rm to 4 bits when using an FP16 register.  This restriction
does not apply for all instructions, e.g. fcmla does not have this restriction
as it gets an extra bit from the M field.

Unfortunately, this restriction to S_H was added for all _Em operands before,
meaning for a large number of instructions you couldn't use the full register
file.

This fixes the issue by introducing a new operand _Em16 which applies this
restriction only when paired with S_H and leaves the _Em and the other
qualifiers for _Em16 unbounded (i.e. using the full 5 bit range).

Also the patch updates all instructions that should be affected by this.

4b8e28c793 xtensa: use property tables for correct disassembly 
xtensa disassembler does not use information from the .xt.prop sections
to switch between code/data disassembly in text sections. This may
result in incorrect disassembly when data is interpreted as code and
disassembler loses synchronization with instruction stream. Use .xt.prop
section information to correctly interpret code and data and synchronize
with instruction stream.

f9830ec165 Implement Read/Write constraints on system registers on AArch64 
This patch adds constraints for read and write only system registers with the
msr and mrs instructions.  The code will treat having both flags set and none
set as the same.  These flags add constraints that must be matched up. e.g. a
system register with a READ only flag set, can only be used with mrs.  If The
constraint fails a warning is emitted.

Examples of the warnings generated:

test.s: Assembler messages:
test.s:5: Warning: specified register cannot be written to at operand 1 -- `msr dbgdtrrx_el0,x3'
test.s:7: Warning: specified register cannot be read from at operand 2 -- `mrs x3,dbgdtrtx_el0'
test.s:8: Warning: specified register cannot be written to at operand 1 -- `msr midr_el1,x3'

and disassembly notes:

0000000000000000 <main>:
   0:	d5130503 	msr	dbgdtrtx_el0, x3
   4:	d5130503 	msr	dbgdtrtx_el0, x3
   8:	d5330503 	mrs	x3, dbgdtrrx_el0
   c:	d5330503 	mrs	x3, dbgdtrrx_el0
  10:	d5180003 	msr	midr_el1, x3	; note: writing to a read-only register.

Note that because dbgdtrrx_el0 and dbgdtrtx_el0 have the same encoding, during
disassembly the constraints are use to disambiguate between the two.  An exact
constraint match is always prefered over partial ones if available.

As always the warnings can be suppressed with -w and also be made errors using
warnings as errors.

7d02540ab7 Allow non-fatal errors to be emitted and for disassembly notes be placed on AArch64 
This patch adds a new platform option "notes" that can be used to indicate if
disassembly notes should be placed in the disassembly as comments.

These notes can contain information about a failing constraint such as reading
from a write-only register.  The disassembly will not be blocked because of this
but -M notes will emit a comment saying that the operation is not allowed.

For assembly this patch adds a new non-fatal status for errors.  This is
essentially a warning.  The reason for not creating an actual warning type is
that this causes the interaction between the ordering of warnings and errors to
be problematic.  Currently the error buffer is almost always filled because of
the way operands are matched during assembly. An earlier template may have put
an error there that would only be displayed if no other template matches or
generates a higher priority error.  But by definition a warning is lower
priority than a warning, so the error (which is incorrect if another template
matched) will supersede the warning.  By treating warnings as errors and only
later relaxing the severity this relationship keeps working and the existing
reporting infrastructure can be re-used.

561a72d4dd Modify AArch64 Assembly and disassembly functions to be able to fail and report why. 
This patch if the first patch in a series to add the ability to add constraints
to system registers that an instruction must adhere to in order for the register
to be usable with that instruction.

These constraints can also be used to disambiguate between registers with the
same encoding during disassembly.

This patch adds a new flags entry in the sysreg structures and ensures it is
filled in and read out during assembly/disassembly. It also adds the ability for
the assemble and disassemble functions to be able to gracefully fail and re-use
the existing error reporting infrastructure.

The return type of these functions are changed to a boolean to denote success or
failure and the error structure is passed around to them. This requires
aarch64-gen changes so a lot of the changes here are just mechanical.
