Pointer Authentication is a new feature in AArch64 v8.3-a. When enabled in
the compiler, function return addresses will be mangled by the kernel.
Add register description xml and wire up to aarch64_linux_read_description.
This description includes the two pauth user registers.
Nothing yet uses the feature - that is added in later patches.

This commit applies all changes made after running the gdb/copyright.py
script.
Note that one file was flagged by the script, due to an invalid
copyright header
(gdb/unittests/basic_string_view/element_access/char/empty.cc).
As the file was copied from GCC's libstdc++-v3 testsuite, this commit
leaves this file untouched for the time being; a patch to fix the header
was sent to gcc-patches first.
gdb/ChangeLog:
Update copyright year range in all GDB files.

This commit adds target description support for riscv.
I've used the split feature approach for specifying the architectural
features, and the CSR feature is auto-generated from the riscv-opc.h
header file.
If the target doesn't provide a suitable target description then GDB
will build one by looking at the bfd headers.
This commit does not implement target description creation for the
Linux or FreeBSD native targets, both of these will need to add
read_description methods into their respective target classes, which
probe the target features, and then call
riscv_create_target_description to build a suitable target
description. Until this is done Linux and FreeBSD will get the same
default target description based on the bfd that bare-metal targets
get.
I've only added feature descriptions for 32 and 64 bit registers, 128
bit registers (for RISC-V) are not supported in the reset of GDB yet.
This commit removes the special reading of the MISA register in order
to establish the target features, this was only used for figuring out
the f-register size, and even that wasn't done consistently. We now
rely on the target to tell us what size of registers it has (or look
in the BFD as a last resort). The result of this is that we should
now support RV64 targets with 32-bit float, though I have not
extensively tested this combination yet.

This patch adds support for Hardware Transactional Memory registers
for the powerpc linux native and core file targets, and for the
pwoerpc linux server stub.
These registers include both the HTM special-purpose registers (TFHAR,
TEXASR and TFIAR) as well as the set of registers that are
checkpointed (saved) when a transaction is initiated, which the
processor restores in the event of a transaction failure.
The set of checkpointed general-purpose registers is returned by the
linux kernel in the same format as the regular general-purpose
registers, defined in struct pt_regs. However, the architecture
specifies that only some of the registers present in pt_regs are
checkpointed (GPRs 0-31, CR, XER, LR and CTR). The kernel fills the
slots for MSR and NIP with other info. The other fields usually don't
have meaningful values. GDB doesn't define registers that are not
checkpointed in the architecture, but when generating a core file, GDB
fills the slot for the checkpointed MSR with the regular MSR. These
are usually similar, although some bits might be different, and in
some cases the checkpointed MSR will have a value of 0 in a
kernel-generated core-file. The checkpointed NIP is filled with TFHAR
by GDB in the core-file, which is what the kernel does. The other
fields are set to 0 by GDB.
Core files generated by the kernel have a note section for
checkpointed GPRs with the same size for both 32-bit and 64-bit
threads, and the values for the registers of a 32-bit thread are
squeezed in the first half, with no useful data in the second half.
GDB generates a smaller note section for 32-bit threads, but can read
both sizes.
The checkpointed XER is required to be 32-bit in the target
description documentation, even though the more recent ISAs define it
as 64-bit wide, since the high-order 32-bits are reserved, and because
in Linux there is no way to get a 64-bit checkpointed XER for 32-bit
threads. If this changes in the future, the target description
feature requirement can be relaxed to allow for a 64-bit checkpointed
XER.
Access to the checkpointed CR (condition register) can be confusing.
The architecture only specifies that CR fields 1 to 7 (the 24 least
significant bits) are checkpointed, but the kernel provides all 8
fields (32 bits). The value of field 0 is not masked by ptrace, so it
will sometimes show the result of some kernel operation, probably
treclaim., which sets this field.
The checkpointed registers are marked not to be saved and restored.
Inferior function calls during an active transaction don't work well,
and it's unclear what should be done in this case. TEXASR and TFIAR
can be altered asynchronously, during transaction failure recording,
so they are also not saved and restored. For consistency neither is
TFHAR.
Record and replay also doesn't work well when transactions are
involved. This patch doesn't address this, so the values of the HTM
SPRs will sometimes be innacurate when the record/relay target is
enabled. For instance, executing a "tbegin." alters TFHAR and TEXASR,
but these changes are not currently recorded.
Because the checkpointed registers are only available when a
transaction is active (or suspended), ptrace can return ENODATA when
gdb tries to read these registers and the inferior is not in a
transactional state. The registers are set to the unavailable state
when this happens. When gbd tries to write to one of these registers,
and it is unavailable, an error is raised.
The "fill" functions for checkpointed register sets in the server stub
are not implemented for the same reason as for the EBB register set,
since ptrace can also return ENODATA for checkpointed regsets. The
same issues with 'G' packets apply here.
Just like for the EBB registers, tracepoints will not mark the
checkpointed registers as unavailable if the inferior was not in a
transaction, so their content will also show 0 instead of
<unavailable> when inspecting trace data.
The new tests record the values of the regular registers before
stepping the inferior through a "tbegin." instruction to start a
transaction, then the checkpointed registers are checked against the
recorded pre-transactional values. New values are written to the
checkpointed registers and recorded, the inferior continues until the
transaction aborts (which is usually immediately when it is resumed),
and the regular registers are checked against the recorded values,
because the abort should have reverted the registers to these values.
Like for the EBB registers, target_store_registers will ignore the
checkpointed registers when called with -1 as the regno
argument (store all registers in one go).

This patch prepares the current GDB port of the OpenRISC processor from
https://github.com/openrisc/binutils-gdb for upstream merging.
Testing has been done with a cgen sim provided in a separate patch. This
has been tested with 2 toolchains. GCC [1] 5.4.0 from the OpenRISC
project with Newlib [2] and GCC 5.4.0 with Musl [3] 1.1.4.
It supports or1knd (no delay slot target).
The default target is or1k (with delay slot).
You can change the target arch with:
(gdb) set architecture or1knd
The target architecture is assumed to be or1knd

Nowadays, we have six tic6x expedite registers, which are duplicated.
tic6x-c64xp-expedite = A15,PC
tic6x-c64x-expedite = A15,PC
tic6x-c62x-expedite = A15,PC
tic6x-c64xp-linux-expedite = A15,PC
tic6x-c64x-linux-expedite = A15,PC
tic6x-c62x-linux-expedite = A15,PC
in features/Makefile, we have
echo "expedite:$(if $($*-expedite),$($*-expedite),$($(firstword $(subst -, ,$(notdir $*)))-expedite))" \
>> $(outdir)/$*.tmp
which means for a given bar/foo-baz.xml, we'll look for either
bar/foo-baz-expedite or foo-expedite. We can define only one generic
expedite register for all different ti6cx and s390x target descriptions.
Actually, we've done that for x86 target descriptions.
Re-run 'make GDB=/path/build/gdb all' to regenerate regformats/*.dat files,
and they are not changed.

This patch changes Makefile and command "maint print c-files" so
that GDB can print c files for features instead target description.
Previously, we feed GDB a target description xml file, which generate
c files including multiple features.
With this patch, in Makefile, we wrap each feature xml file, and
create a temp target description which include only one feature.
Then, adjust the target description printer for them, and print
a c function for each given feature, so that we can use these
c functions later to create target description in a flexible way.

Nowadays, we need two steps to print c files for xml target description,
that is, 1) read xml target description in, update the current tdesc,
2) visit the current tdesc, print the c file. It is unnecessary to
involve in current tdesc, and some validations in each gdbarch are
performed unnecessarily, which will reject some target descriptions if
they are missing some mandatory feature.
This patch adds an optional argument to "maint print c-tdesc", which
is an XML file target description, so that we can combine the two
steps above into one step, and don't have to involve in global current
tdesc.

This patch adds support for the registers added by the
Memory Protection Keys for Userspace (PKU aka PKEYs) feature.
Native and remote debugging are covered by this patch.
The XSAVE area is extended with a new state containing
the 32-bit wide PKRU register. The new register is added to
amd64-avx-mpx_avx512-* tdesc, thus it is renamed accordingly. Also,
respective xstate mask X86_XSTATE_AVX_MPX_AVX512_MASK is renamed to
X86_XSTATE_AVX_MPX_AVX512_PKU_MASK to reflect the new feature set
it supports.

Add a dedicated target description for the feature combination
avx-avx512 as implemented by certain IA CPU models.
The corresponding X86_XSTATE_AVX_AVX512_MASK already exists, but shared
the tdesc with X86_XSTATE_AVX_MPX_AVX512_MASK. This caused MPX registers
displayed as undefined on CPUs that only implemented
X86_XSTATE_AVX_AVX512_MASK, which is undesired. This patch solves this issue.
This patch also corrects the wrong usage of x32-avx-mpx-avx512, which is
replaced by x32-avx-avx512. The MPX feature is not implemented in x32 mode.

To better reflect the actual feature set covered by the IA target
descriptions, the existing descriptions are renamed. Each feature of
the extended state is added to the name of a description or xstate mask
starting from AVX.
For example, amd64-mpx-avx512-linux becomes amd64-avx-mpx-avx512-linux,
while amd64-avx-linux remains unchanged.
Likewise, the corresponding xstate masks are changed, e.g. from
X86_XSTATE_MPX_AVX512_MASK to X86_XSTATE_AVX_MPX_AVX512_MASK.

make GDB=/scratch/yao/gdb/build-git/all-targets/gdb/gdb all, some
powerpc .dat files are not generated.
This patch fixes it by adding them to WHICH, so these .dat files can
be generated.

If I delete all target description c files under features/ directory,
and run make GDB=/scratch/yao/gdb/build-git/all-targets/gdb/gdb cfiles,
some s390 target description c files are not generated.
This patch adds these s390 xml files to XMLTOC, so these c files can
be generated.
gdb:
2016-10-05 Yao Qi <yao.qi@linaro.org>
* features/Makefile (XMLTOC): Add s390-tevx-linux64.xml,
s390-vx-linux64.xml, s390x-tevx-linux64.xml and
s390x-vx-linux64.xml.

Nowadays, there are a lot of duplication about
i386/{i386, amd64, x32}*-expedite in features/Makefile. However,
in features/Makefile, we have
echo "expedite:$(if $($*-expedite),$($*-expedite),$($(firstword $(subst -, ,$(notdir $*)))-expedite))" \
>> $(outdir)/$*.tmp
which means for a given bar/foo-baz.xml, we'll look for either
bar/foo-baz-expedite or foo-expedite. In x86 expedite registers, we
use the former now, but it will be much simpler if we use the latter.
This is what this patch does. This patch removes them, and defines
three generic expedite. Re-run 'make GDB=/path/build/gdb all' to
regenerate regformats/*.dat files, and they are not changed.
gdb:
2016-10-05 Yao Qi <yao.qi@linaro.org>

This patch is move features/arm-*.xml to features/arm/, and it is based
on Terry's patch posted here
https://sourceware.org/ml/gdb-patches/2014-06/msg00794.html
One comment to Terry's patch is about losing "arm" prefix, and the new
patch fixes this problem.

ARC is a family of licensable processors developed by Synopsys.
This is an initial patch that doesn't yet support some of the features, that
are already available in Synopsys' fork of GDB, namely:
* longjmp support
* signal frame handling
* prologue analysis
* Linux targets support
* native Linux support
ARC cores are configurable and extensible, which means from debugger
perspective that some registers and debug capabilities are optional, therefore
it is up to the GDB stub to determine exact list of register available on
target and supply it to GDB via XML target descriptions. List of registers
that is known to GDB and is required is intentionally kept small to simplify
requirements to GDB stub and implementation of a GDB client.

The current MPX target descriptions assume that MPX is always combined
with AVX, however that's not correct. We can have machines with MPX
and without AVX; or machines with AVX and without MPX.
This patch adds new target descriptions for machines that support
both MPX and AVX, as duplicates of the existing MPX descriptions.
The following commit will remove AVX from the MPX-only descriptions.

This makes it easier to rebuild all GDB's generated target description
C files.
It also clarifies the comments a bit. One might think we need a GDB
configured for the particular arquitecture (--target=foo). But a
build that includes support for the target description is sufficient.
(GDB rejects target descriptions that explicitly specify the
architecture, with an <architecture> element, if the architecture is
unknown.)
Tested that "make clean-cfiles" deletes all .c files under
src/gdb/features/, and that "make cfiles" generates them all without
error, and that diffing the newly generated C files against master
comes out an empty diff.

The only reason .dat files exist is for GBBserver to use them in its
build system.
A few .dat files are listed as targets for generation that shouldn't.
The target descriptions these files are built from aren't used by
GDBserver. They're fallback descriptions GDB itself has baked in.
Remove them from the list of .dat files to be generated, otherwise a
plain "make" under src/gdb/features/ generates new .dat files that
aren't even in the tree today.

Prior to version MicroBlaze v8.10.a,EDK 13.1, XMD's gdbserver stub returned 57
registers in response to GDB's G request. Starting with version MicroBlaze
v8.10.a, EDK 13.1, XMD added the slr and shr register, for a count of 59
registers. This patch adds these registers to the expected G response. This patch
fixes the above problem for baremetal and also supports the backward compatibility.

This patch adds support for the Intel(R) Advanced Vector
Extensions 512 (Intel(R) AVX-512) registers. Native and remote
debugging are covered by this patch.
Intel(R) AVX-512 is an extension to AVX to support 512-bit wide
SIMD registers in 64-bit mode (XMM0-XMM31, YMM0-YMM31, ZMM0-ZMM31).
The number of available registers in 32-bit mode is still 8
(XMM0-7, YMM0-7, ZMM0-7). The lower 256-bits of the ZMM registers
are aliased to the respective 256-bit YMM registers. The lower
128-bits are aliased to the respective 128-bit XMM registers.
There are also 8 new, dedicated mask registers (K0-K7) in both 32-bit
mode and 64-bit mode.
