87c69f9732 Rename PowerPC64 pcrel GOT TLS relocations
These relocations should have had REL in their names, to reflect the
fact that they are pc-relative.  Fix that now by adding _PCREL.
I've added some back-compatibility code to support anyone using
.reloc with the old relocations.

e9bffec9af opcodes: discriminate endianness and insn-endianness in CGEN ports
The CGEN support code in opcodes accesses instruction contents using a
couple of functions defined in cgen-opc.c: cgen_get_insn_value and
cgen_put_insn_value.  These functions use the "instruction endianness"
in the CPU description to order the read/written bytes.

The process of writing an instruction to the object file is:

  a) cgen_put_insn_value        ;; Writes out the opcodes.
  b) ARCH_cgen_insert_operand
       insert_normal
         insert_1
           cgen_put_insn_value  ;; Writes out the bytes of the
                                ;; operand.

Likewise, the process of reading an instruction from the object file
is:

  a) cgen_get_insn_value        ;; Reads the opcodes.
  b) ARCH_cgen_extract_operand
       extract_normal
         extract_1
           cgen_get_insn_value  ;; Reads in the bytes of the
                                ;; operand.

As can be seen above, cgen_{get,put}_insn_value are used to both
process the instruction opcodes (the constant fields conforming the
base instruction) and also the values of the instruction operands,
such as immediates.

This is problematic for architectures in which the endianness of
instructions is different to the endianness of data.  An example is
BPF, where instructions are always encoded big-endian but the data may
be either big or little.

This patch changes the cgen_{get,put}_insn_value functions in order to
get an extra argument with the endianness to use, and adapts the
existin callers to these functions in order to provide cd->endian or
cd->insn_endian, whatever appropriate.  Callers like extract_1 and
insert_1 pass cd->endian (since they are reading/writing operand
values) while callers reading/writing the base instruction pass
cd->insn_endian instead.

A few little adjustments have been needed in some existing CGEN based
ports:
* The BPF assembler uses cgen_put_insn_value.  It has been adapted to
  pass the new endian argument.
* The mep port has code in mep.opc that uses cgen_{get,put}_insn_value.
  It has been adapted to pass the new endianargument.  Ditto for a
  call in the assembler.

Tested with --enable-targets=all.
Regested in all supported targets.
No regressions.

b3db6d07be opcodes: support insn endianness in cgen_cpu_open
This patch adds support for a new CGEN_OPEN_INSN_ENDIAN argument
for @arch@_cgen_cpu_open.  This is useful for architectures in
which the endianness of the instruction words is not the same
than the endianness used for data.

An accompanying patch has been sent to the CGEN mailing list that
adds support for this argument on the CGEN side [1].  Its been
already pre-approved [2], and will be applied simultaneously with
this binutils series.

44730156af RISC-V: Fix the error when building RISC-V linux native gdbserver.
The original report is as follow,
https://sourceware.org/pipermail/binutils/2020-June/111383.html

Inlcude the bfd.h in the include/opcode/riscv.h may cause gdbserver fail
to build.  I just want to use the `bfd_boolean` in the opcodes/riscv-opc.c,
but I didn't realize this cause the build failed.  Fortunately, I can also
use the `int` as the function return types just like others in the
opcodes/riscv-opc.c.

8eff95bcb6 PR26044, Some targets can't be compiled with GCC 10 (tilepro)
Since this value is used in fields of type tilepro_pipeline (as
NO_PIPELINE, see tc-tilepro.c) it is appropriate to put it in
the tilepro_pipelen enum.  This avoids a warning about converting from
one enum type to another.

8f595e9b4f [PATCH v2 0/9] RISC-V: Support version controling for ISA standard extensions and CSR
1. Remove the -mriscv-isa-version and --with-riscv-isa-version options.
We can still use -march to choose the version for each extensions, so there is
no need to add these.

2. Change the arguments of options from [1p9|1p9p1|...] to [1.9|1.9.1|...].
Unlike the architecture string has specified by spec, ther is no need to do
the same thing for options.

3. Spilt the patches to reduce the burdens of review.

[PATCH 3/7] RISC-V: Support new GAS options and configure options to set ISA versions
to
[PATCH v2 3/9] RISC-V: Support GAS option -misa-spec to set ISA versions
[PATCH v2 4/9] RISC-V: Support configure options to set ISA versions by default.

to
[PATCH v2 5/9] RISC-V: Support version checking for CSR according to privilege spec version.
[PATCH v2 6/9] RISC-V: Support configure option to choose the privilege spec version.

4. Use enum class rather than string to compare the choosen ISA spec in opcodes/riscv-opc.c.
The behavior is same as comparing the choosen privilege spec.

	define_version and abort_version.  The define_version means which
	privilege spec is started to define the CSR, and the abort_version
	means which privilege spec is started to abort the CSR.  If the CSR is
	valid for the newest spec, then the abort_version should be
	PRIV_SPEC_CLASS_DRAFT.
	(DECLARE_CSR_ALIAS): Same as DECLARE_CSR, but only for the obselete CSR.
	* opcode/riscv.h (enum riscv_priv_spec_class): New enum class.  Define

2745674244 arc: Add support for ARC HS extra registers in core files
When a coredump is generated, there are a few registers in
ARC HS that are put under a special section, namely ".reg-v2".
It is for backward compatibility reasons with older tools that
we have decided not to extend the generic ".reg" section.

This patch makes it possible to display the information better
regarding that section.  Compare the output of "readelf" without
and with these changes:

$ readelf -n core     # without the patch
  ...
  LINUX    0x0000000c  Unknown note type: (0x00000600)
   description data: 78 08 00 00 2f 6c 64 2d 75 43 6c 69

$ readelf -n core     # with the patch
  ...
  LINUX    0x0000000c  NT_ARC_V2 (ARC HS accumulator/extra registers)
   description data: 78 08 00 00 2f 6c 64 2d 75 43 6c 69

In another commit (soon to be submitted), GDB will makes use of these
changes to parse the extra section and its registers.

4d095f5b5e coff-go32-exe: support variable-length stubs
The stub size in GO32 executables has historically been fixed at 2048
bytes, due to hardcoded limitations in bfd.  Recent patches to djgpp by
Stas Sergeev (CC'd) have pushed the stub right up to this limit, so if
any further expansion is desired, this must first be patched in bfd.

This series includes three patches:  The first changes the meaning of
the bfd->origin field slightly, so that target code can use this to
specify an offset into the file where the actual bfd is located.
The second patch then uses this to enable support for variable-sized
stubs in the coff-go32-exe format.
The final patch is only a cleanup, it normalizes function and variable
names in coff-stgo32.c so that they all begin with the same prefix.

	bfd->origin to file offset.

This commit pulls in the latest changes for the include/ and
libiberty/ directories.  The last sync was in commit
533da48302.

This commit also removes the file libiberty/rust-demangle.h, this file
has been removed in upstream GCC, and should have been deleted as part
of the previous sync up, which included this ChangeLog entry:

  2019-11-16  Eduard-Mihai Burtescu  <eddyb@lyken.rs>

        ....
	* rust-demangle.h: Remove.

I've grep'd over the binutils-gdb source and can find no reference to
the rust-demangle.h file, and everything seems to build fine without
it, so I assume its continued existence was a mistake.

bd0cf5a6ba RISC-V: Support the ISA-dependent CSR checking.
According to the riscv privilege spec, some CSR are only valid when rv32 or
the specific extension is set.  We extend the DECLARE_CSR and DECLARE_CSR_ALIAS
to record more informaton we need, and then check whether the CSR is valid
according to these information.  We report warning message when the CSR is
invalid, so we have a choice between error and warning by --fatal-warnings
option.  Also, a --no-warn/-W option is used to turn the warnings off, if
people don't want the warnings.

	gas/
	* config/tc-riscv.c (enum riscv_csr_class): New enum.  Used to decide
	whether or not this CSR is legal in the current ISA string.
	(struct riscv_csr_extra): New structure to hold all extra information
	of CSR.
	(riscv_init_csr_hash): New function.  According to the DECLARE_CSR and
	DECLARE_CSR_ALIAS, insert CSR extra information into csr_extra_hash.
	Call hash_reg_name to insert CSR address into reg_names_hash.
	(md_begin): Call riscv_init_csr_hashes for each DECLARE_CSR.
	(reg_csr_lookup_internal, riscv_csr_class_check): New functions.
	Decide whether the CSR is valid according to the csr_extra_hash.
	(init_opcode_hash): Update 'if (hash_error != NULL)' as hash_error is
	not a boolean.  This is same as riscv_init_csr_hash, so keep the
	consistent usage.

	* testsuite/gas/riscv/csr-dw-regnums.d: Add -march=rv32if option.
	* testsuite/gas/riscv/priv-reg.d: Add f-ext by -march option.
	* testsuite/gas/riscv/priv-reg-fail-fext.d: New testcase.  The source

4934a27c8c [binutils][arm] arm support for ARMv8.m Custom Datapath Extension
This patch is part of a series that adds support for the Armv8.m
ARMv8.m Custom Datapath Extension to binutils.

This patch introduces the Custom Instructions Class 1/2/3 (Single/
Dual, Accumulator/Non-accumulator varianats) to the arm backend.

The following Custom Instructions are added: cx1, cx1a,
cx1d, cx1da, cx2, cx2a, cx2d, cx2da, cx3, cx3a, cx3d, cx3da.

Specification can be found at
https://developer.arm.com/docs/ddi0607/latest

This patch distinguishes between enabling CDE for different coprocessor
numbers by defining multiple architecture flags.  This means that the
parsing of the architecture extension flags is kept entirely in the
existing code path.

We introduce a new IT block state to indicate the behaviour of these
instructions.  This new state allows being used in an IT block or
outside an IT block, but does not allow the instruction to be used
inside a VPT block.
We need this since the CX*A instruction versions can be used in IT
blocks, but they aren't to have the conditional suffixes on them.  Hence
we need to mark an instruction as allowed in either position.

We also need a new flag to objdump, in order to determine whether to
disassemble an instruction as CDE related or not.

Successfully regression tested on arm-none-eabi, and arm-wince-pe.

2da2eaf4ce [binutils][arm] PR25376 Change MVE into a CORE_HIGH feature
This patch moves MVE feature bits into the CORE_HIGH section.  This makes sure
.fpu and -mfpu does not reset the bits set by MVE. This is important because
.fpu has no option to "set" these same bits and thus, mimic'ing GCC, we choose
to define MVE as an architecture extension rather than put it together with
other the legacy fpu features.

This will enable the following behavior:
.arch armv8.1-m.main
.arch mve
.fpu fpv5-sp-d16               #does not disable mve.
vadd.i32 q0, q1, q2

This patch also makes sure MVE is not taken into account during auto-detect.
This was already the case, but because we moved the MVE bits to the
architecture feature space we must make sure ARM_ANY does not include MVE.

5496abe1c5 tic4x: sign extension using shifts
Don't do that.  Especially don't use shift counts that assume the type
being shifted is 32 bits when the type is long/unsigned long.  Also
reverts part of a change I made on 2019-12-11 to tic4x_print_register
that on closer inspection turns out to be unnecessary.

include/
	* opcode/tic4x.h (EXTR): Delete.
	(EXTRU, EXTRS, INSERTU, INSERTS): Rewrite without zero/sign
	extension using shifts.  Do trim INSERTU value to specified bitfield.

8948cc6971 ubsan: spu: left shift of negative value
Also fixes a real bug.  The DECODE_INSN_I9a and DECODE_INSN_I9b both
use UNSIGNED_EXTRACT for 7 low bits of the result, but this was an
unsigned value due to "insn" being unsigned.  DECODE_INSN_I9* is
therefore unsigned too, leading to a zero extension in an expression
using a bfd_vma if bfd_vma is 64 bits.

	* opcode/spu.h: Formatting.
	(UNSIGNED_EXTRACT): Use 1u.
	(SIGNED_EXTRACT): Don't sign extend with shifts.
	(DECODE_INSN_I9a, DECODE_INSN_I9b): Avoid left shift of signed value.
	Keep result signed.
	(DECODE_INSN_U9a, DECODE_INSN_U9b): Delete.
