0d12e84cfc Don't include gdbarch.h from defs.h
I touched symtab.h and was surprised to see how many files were
rebuilt.  I looked into it a bit, and found that defs.h includes
gdbarch.h, which in turn includes many things.

gdbarch.h is only needed by a minority ofthe files in gdb, so this
patch removes the include from defs.h and updates the fallout.

I did "wc -l" on the files in build/gdb/.deps; this patch reduces the
line count from 139935 to 137030; so there are definitely future
build-time savings here.

Note that while I configured with --enable-targets=all, it's possible
that some *-nat.c file needs an update.  I could not test all of
these.  The buildbot caught a few problems along these lines.

6f072a1034 [PowerPC] Aliases for vector registers
This patch defines pseudo-registers "v0" through "v31" as aliases that
map to the corresponding raw "vr0" through "vr31" vector registers for
Power.

The motivation behind this is that although GDB defines these
registers as "vrX", the disassembler prints them as "vX", e.g. as the
operands in instructions such as "vaddubm v2,v1,v1".  This can be
confusing to users trying to print out the values of the operands
while inspecting the disassembled code.

The new aliases are made not to belong to any register group, to avoid
duplicated values in "info register vector" and "info register all".
The arch-specific rs6000_pseudo_register_reggroup_p function had
previously been removed since the other pseudo-registers could have
their groups inferred by their type.  It restored with this patch to
handle the aliases.  Membership for the other pseudo-registers is
still determined using the default function.

A new tests checks that GDB prints the expected values of vector
registers after they are filled by the inferior, by using both the raw
names and the aliases.  Two other existing tests are modified to also
test the aliases.

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.

8d619c01db [PowerPC] Add support for HTM registers
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).

232bfb8644 [PowerPC] Add support for EBB and PMU registers
This patch adds support for registers of the Event Based Branching and
Performance Monitoring Units for the powerpc linux native and core
file targets, and for the powerpc linux server stub.

All three EBB registers are accessible.  Only a subset of the PMU
registers can be accessed through ptrace.  Because of this, the PMU
registers are enumerated individually in gdbarch_tdep, as opposed to
having a single "have_pmu" flag.  This is intended to make it easier
to add additional PMU registers in the future, since checking a
"have_pmu" flag elsewhere in the code would no longer be correct.  The
tdesc feature is named org.gnu.gdb.power.linux.pmu because of this.

It's unclear if it makes sense to save and restore these registers
across function calls, since some of them can be modified
asynchronously.  They are also not tracked in record-replay mode.

The kernel can return ENODATA when ptrace is used to get the EBB
registers, unless a linux performance event that uses EBB is open in
the inferior.  For this reason, the "fill" functions in the server
stub for the ebb register sets is not implemented.

Since gdbserver writes all registers in one go before resuming the
inferior, this error would not be detected at the time the user tries
to write to one of the registers on the client side, and gdbserver
would print out warnings every time it resumes the inferior when no
ebb performance event is opened, so there is currently no
straightforward way to handle this case.  This means the ebb registers
in the client-side regcache can become dirty when the user tries to
write to them, until the inferior is resumed and stopped again.

A related issue is that 'G' packets used to write to unrelated
registers will include bad data for the EBB registers if they are
unavailable, since no register status information is included in the
'G' packet.  This data won't be written to the inferior by the
gdbserver stub because the "fill" functions are not implemented, and
currently the gdbserver stub doesn't change the status of the
registers in its own regcache in response to 'G' packets.

Another limitation for the ebb registers is that traceframes don't
record if registers are available or not, so if these registers are
collected when a tracepoint is hit and the inferior has no ebb event
opened, the user will see zero values for all of them, instead of the
usual <unavailable>.

Because these registers are often unavailable, trying to store them
with target_store_registers with -1 for the regno argument (all
registers) would almost always fail, so they are ignored in this case.

1d75a65809 [PowerPC] Fix access to VSCR in linux targets
The 4-byte VSCR register is found inside a 16-byte field in the regset
returned by ptrace and in core files. The position of VSCR depends on
the endianess of the target, which was previously assumed to be
big-endian for the purpose of getting VSCR. This patch removes this
assumption to fix access to VSCR in little-endian mode.

This patch fixes a number of bugs in ppc32 plt stub matching code.
1) The 4-insn stubs for shared libs and PIEs weren't matched.

ed0f427344 [PowerPC] Detect different long double floating-point formats
Current versions of GCC support switching the format used for "long double"
to either IBM double double or IEEE-128.  The resulting binary is marked
via different setting of the Tag_GNU_Power_ABI_FP GNU attribute.

This patch checks this attribute to detect the format of the default
"long double" type and sets GDB's notion of the format accordingly.

The patch also adds support for the "__ibm128" type, which always uses
IBM double double format independent of the format used for "long double".

A new test case verifies that all three types, "long double", "__float128",
and "__ibm128" are correctly detected in all three compiler settings,
the default setting, -mabi=ieeelongdouble, and -mabi=ibmlongdouble.

cd453cd072 PowerPC64 ELFv2 ABI: base support
This is the first patch of a series to implement support for the
PowerPC ELFv2 ABI.  While powerpc64le-linux will use ELFv2, and
the existing powerpc64-linux code will continue to use ELFv1,
in theory ELFv2 is also defined for big-endian systems (and
ELFv1 was also defined for little-endian systems).

Therefore this patch adds a new tdep->elf_abi variable to decide
which ABI version to use.  This is detected from the ELF header
e_flags value; if this is not present, we default to ELFv2 on
little-endian and ELFv1 otherwise.

This patch does not yet introduce any actual difference in GDB's
handling of the two ABIs.  Those will be added by the remainder
of this patch series.

For an overview of the changes in ELFv2, have a look at the
comments in the patch series that added ELFv2 to GCC, starting at:

28e7fd6234 Update years in copyright notice for the GDB files.
Two modifications:
  1. The addition of 2013 to the copyright year range for every file;
