This changes GDB to use frame_info_ptr instead of frame_info *
The substitution was done with multiple sequential `sed` commands:
sed 's/^struct frame_info;/class frame_info_ptr;/'
sed 's/struct frame_info \*/frame_info_ptr /g' - which left some
issues in a few files, that were manually fixed.
sed 's/\<frame_info \*/frame_info_ptr /g'
sed 's/frame_info_ptr $/frame_info_ptr/g' - used to remove whitespace
problems.
The changed files were then manually checked and some 'sed' changes
undone, some constructors and some gets were added, according to what
made sense, and what Tromey originally did

I built GDB for all targets on a x86-64/GNU-Linux system, and
then (accidentally) passed GDB a RISC-V binary, and asked GDB to "run"
the binary on the native target. I got this error:
(gdb) show architecture
The target architecture is set to "auto" (currently "i386").
(gdb) file /tmp/hello.rv32.exe
Reading symbols from /tmp/hello.rv32.exe...
(gdb) show architecture
The target architecture is set to "auto" (currently "riscv:rv32").
(gdb) run
Starting program: /tmp/hello.rv32.exe
../../src/gdb/i387-tdep.c:596: internal-error: i387_supply_fxsave: Assertion `tdep->st0_regnum >= I386_ST0_REGNUM' failed.
What's going on here is this; initially the architecture is i386, this
is based on the default architecture, which is set based on the native
target. After loading the RISC-V executable the architecture of the
current inferior is updated based on the architecture of the
executable.
When we "run", GDB does a fork & exec, with the inferior being
controlled through ptrace. GDB sees an initial stop from the inferior
as soon as the inferior comes to life. In response to this stop GDB
ends up calling save_stop_reason (linux-nat.c), which ends up trying
to read register from the inferior, to do this we end up calling
target_ops::fetch_registers, which, for the x86-64 native target,
calls amd64_linux_nat_target::fetch_registers.
After this I eventually end up in i387_supply_fxsave, different x86
based targets will end in different functions to fetch registers, but
it doesn't really matter which function we end up in, the problem is
this line, which is repeated in many places:
i386_gdbarch_tdep *tdep = (i386_gdbarch_tdep *) gdbarch_tdep (arch);
The problem here is that the ARCH in this line comes from the current
inferior, which, as we discussed above, will be a RISC-V gdbarch, the
tdep field will actually be of type riscv_gdbarch_tdep, not
i386_gdbarch_tdep. After this cast we are relying on undefined
behaviour, in my case I happen to trigger an assert, but this might
not always be the case.
The thing I tried that exposed this problem was of course, trying to
start an executable of the wrong architecture on a native target. I
don't think that the correct solution for this problem is to detect,
at the point of cast, that the gdbarch_tdep object is of the wrong
type, but, I did wonder, is there a way that we could protect
ourselves from incorrectly casting the gdbarch_tdep object?
I think that there is something we can do here, and this commit is the
first step in that direction, though no actual check is added by this
commit.
This commit can be split into two parts:
(1) In gdbarch.h and arch-utils.c. In these files I have modified
gdbarch_tdep (the function) so that it now takes a template argument,
like this:
template<typename TDepType>
static inline TDepType *
gdbarch_tdep (struct gdbarch *gdbarch)
{
struct gdbarch_tdep *tdep = gdbarch_tdep_1 (gdbarch);
return static_cast<TDepType *> (tdep);
}
After this change we are no better protected, but the cast is now
done within the gdbarch_tdep function rather than at the call sites,
this leads to the second, much larger change in this commit,
(2) Everywhere gdbarch_tdep is called, we make changes like this:
- i386_gdbarch_tdep *tdep = (i386_gdbarch_tdep *) gdbarch_tdep (arch);
+ i386_gdbarch_tdep *tdep = gdbarch_tdep<i386_gdbarch_tdep> (arch);
There should be no functional change after this commit.
In the next commit I will build on this change to add an assertion in
gdbarch_tdep that checks we are casting to the correct type.

Add missing support for recording of linux syscall getrandom.
Tested on x86_64-linux with native and target board unix/-m32.

When running test-case gdb.reverse/pipe-reverse.exp on openSUSE Tumbleweed,
I run into:
...
(gdb) continue^M
Continuing.^M
Process record and replay target doesn't support syscall number 293^M
Process record: failed to record execution log.^M
^M
Program stopped.^M
0x00007ffff7daabdb in pipe () from /lib64/libc.so.6^M
(gdb) FAIL: gdb.reverse/pipe-reverse.exp: continue to breakpoint: marker2
...
The current glibc on Tumbleweed is 2.35, which contains commit
"linux: Implement pipe in terms of __NR_pipe2", and consequently syscall pipe2
is used in stead of syscall pipe.
There is already support added for syscall pipe2 for aarch64 (which only has
syscall pipe2, not syscall pipe), so enable the same for amd64, by:
- adding amd64_sys_pipe2 in enum amd64_syscall
- translating amd64_sys_pipe2 to gdb_sys_pipe2 in amd64_canonicalize_syscall
Tested on x86_64-linux, specifically on:
- openSUSE Tumbleweed (with glibc 2.35), and
- openSUSE Leap 15.3 (with glibc 2.31).

Change gdbarch_register_reggroup_p to take a 'const struct reggroup *'
argument. This requires a change to the gdb/gdbarch-components.py
script, regeneration of gdbarch.{c,h}, and then updates to all the
architectures that implement this method.
There should be no user visible changes after this commit.

The process record code often emits unfiltered output. In some cases,
this output ought to go to gdb_stderr (but see below). In other
cases, the output is guarded by a logging variable and so ought to go
to gdb_stdlog. This patch makes these changes.
Note that in many cases, the output to stderr is followed by a
"return -1", which is how process record indicates an error. It seems
to me that calling error here would be preferable, because, in many
cases, that's all the caller does when it sees a -1. However, I
haven't made this change.
This is part of PR gdb/7233.

I think it would make sense for extract_integer, extract_signed_integer
and extract_unsigned_integer to take an array_view. This way, when we
extract an integer, we can validate that we don't overflow the buffer
passed by the caller (e.g. ask to extract a 4-byte integer but pass a
2-byte buffer).
- Change extract_integer to take an array_view
- Add overloads of extract_signed_integer and extract_unsigned_integer
that take array_views. Keep the existing versions so we don't
need to change all callers, but make them call the array_view
versions.
This shortens some places like:
result = extract_unsigned_integer (value_contents (result_val).data (),
TYPE_LENGTH (value_type (result_val)),
byte_order);
into
result = extract_unsigned_integer (value_contents (result_val), byte_order);
value_contents returns an array view that is of length
`TYPE_LENGTH (value_type (result_val))` already, so the length is
implicitly communicated through the array view.

I would like to be able to use non-trivial types in gdbarch_tdep types.
This is not possible at the moment (in theory), because of the one
definition rule.
To allow it, rename all gdbarch_tdep types to <arch>_gdbarch_tdep, and
make them inherit from a gdbarch_tdep base class. The inheritance is
necessary to be able to pass pointers to all these <arch>_gdbarch_tdep
objects to gdbarch_alloc, which takes a pointer to gdbarch_tdep.
These objects are never deleted through a base class pointer, so I
didn't include a virtual destructor. In the future, if gdbarch objects
deletable, I could imagine that the gdbarch_tdep objects could become
owned by the gdbarch objects, and then it would become useful to have a
virtual destructor (so that the gdbarch object can delete the owned
gdbarch_tdep object). But that's not necessary right now.
It turns out that RISC-V already has a gdbarch_tdep that is
non-default-constructible, so that provides a good motivation for this
change.
Most changes are fairly straightforward, mostly needing to add some
casts all over the place. There is however the xtensa architecture,
doing its own little weird thing to define its gdbarch_tdep. I did my
best to adapt it, but I can't test those changes.

The r_ldsomap field is specific to Solaris (part of librtld_db), and
should never be accessed for Linux. glibc is planning to add a field
to support multiple namespaces. But there will be no r_ldsomap when
r_version is bumped to 2. Add linux_[ilp32|lp64]_fetch_link_map_offsets
to set r_ldsomap_offset to -1 and use them for Linux targets.

This patch converts the most obvious functions from gdb/frame.h to use
the gdb::array_view abstraction. I've converted the ones that used buffer +
length.
There are others using only the buffer, with an implicit size. I did not
touch those for now. But it would be nice to pass the size for safety.
Tested with --enable-targets=all on Ubuntu 18.04/20.04 aarch64-linux.

As observed on a binary compiled on AMD64 Ubuntu 20.04, against glibc
2.31 (I think it's the libc that provides this startup code, right?),
there are enough bytes at the executable's entry point to hold more than
one displaced step buffer. gdbarch_max_insn_length is 16, and the
code at _start looks like:
0000000000001040 <_start>:
1040: f3 0f 1e fa endbr64
1044: 31 ed xor %ebp,%ebp
1046: 49 89 d1 mov %rdx,%r9
1049: 5e pop %rsi
104a: 48 89 e2 mov %rsp,%rdx
104d: 48 83 e4 f0 and $0xfffffffffffffff0,%rsp
1051: 50 push %rax
1052: 54 push %rsp
1053: 4c 8d 05 56 01 00 00 lea 0x156(%rip),%r8 # 11b0 <__libc_csu_fini>
105a: 48 8d 0d df 00 00 00 lea 0xdf(%rip),%rcx # 1140 <__libc_csu_init>
1061: 48 8d 3d c1 00 00 00 lea 0xc1(%rip),%rdi # 1129 <main>
1068: ff 15 72 2f 00 00 callq *0x2f72(%rip) # 3fe0 <__libc_start_main@GLIBC_2.2.5>
106e: f4 hlt
106f: 90 nop
The two buffers would occupy [0x1040, 0x1060).
I checked on Alpine, which uses the musl C library, the startup code
looks like:
0000000000001048 <_start>:
1048: 48 31 ed xor %rbp,%rbp
104b: 48 89 e7 mov %rsp,%rdi
104e: 48 8d 35 e3 2d 00 00 lea 0x2de3(%rip),%rsi # 3e38 <_DYNAMIC>
1055: 48 83 e4 f0 and $0xfffffffffffffff0,%rsp
1059: e8 00 00 00 00 callq 105e <_start_c>
000000000000105e <_start_c>:
105e: 48 8b 37 mov (%rdi),%rsi
1061: 48 8d 57 08 lea 0x8(%rdi),%rdx
1065: 45 31 c9 xor %r9d,%r9d
1068: 4c 8d 05 47 01 00 00 lea 0x147(%rip),%r8 # 11b6 <_fini>
106f: 48 8d 0d 8a ff ff ff lea -0x76(%rip),%rcx # 1000 <_init>
1076: 48 8d 3d 0c 01 00 00 lea 0x10c(%rip),%rdi # 1189 <main>
107d: e9 9e ff ff ff jmpq 1020 <__libc_start_main@plt>
Even though there's a _start_c symbol, it all appears to be code that
runs once at the very beginning of the program, so it looks fine if the
two buffers occupy [0x1048, 0x1068).
One important thing I discovered while doing this is that when debugging
a dynamically-linked executable, breakpoints in the shared library
loader are hit before executing the _start code, and these breakpoints
may be displaced-stepped. So it's very important that the buffer bytes
are restored properly after doing the displaced steps, otherwise the
_start code will be corrupted once we try to execute it.
Another thing that made me think about is that library constructors (as
in `__attribute__((constructor))`) run before _start. And they are free
to spawn threads. What if one of these threads executes a displaced
step, therefore changing the bytes at _start, while the main thread
executes _start? That doesn't sound good and I don't know how we could
prevent it. But this is a problem that predates the current patch.
Even when stress-testing the implementation, by making many threads do
displaced steps over and over, I didn't see a significant performance (I
confirmed that the two buffers were used by checking the "set debug
displaced" logs though). However, this patch mostly helps make the
feature testable by anybody with an AMD64/Linux machine, so I think it's
useful.
gdb/ChangeLog:
* amd64-linux-tdep.c (amd64_linux_init_abi): Pass 2 as the
number of displaced step buffers.

The displaced_step_buffer class, introduced in the previous patch,
manages access to a single displaced step buffer. Change it into
displaced_step_buffers (note the plural), which manages access to
multiple displaced step buffers.
When preparing a displaced step for a thread, it looks for an unused
buffer.
For now, all users still pass a single displaced step buffer, so no real
behavior change is expected here. The following patch makes a user pass
more than one buffer, so the functionality introduced by this patch is
going to be useful in the next one.

displaced steps
Today, GDB only allows a single displaced stepping operation to happen
per inferior at a time. There is a single displaced stepping buffer per
inferior, whose address is fixed (obtained with
gdbarch_displaced_step_location), managed by infrun.c.
In the case of the AMD ROCm target [1] (in the context of which this
work has been done), it is typical to have thousands of threads (or
waves, in SMT terminology) executing the same code, hitting the same
breakpoint (possibly conditional) and needing to to displaced step it at
the same time. The limitation of only one displaced step executing at a
any given time becomes a real bottleneck.
To fix this bottleneck, we want to make it possible for threads of a
same inferior to execute multiple displaced steps in parallel. This
patch builds the foundation for that.
In essence, this patch moves the task of preparing a displaced step and
cleaning up after to gdbarch functions. This allows using different
schemes for allocating and managing displaced stepping buffers for
different platforms. The gdbarch decides how to assign a buffer to a
thread that needs to execute a displaced step.
On the ROCm target, we are able to allocate one displaced stepping
buffer per thread, so a thread will never have to wait to execute a
displaced step.
On Linux, the entry point of the executable if used as the displaced
stepping buffer, since we assume that this code won't get used after
startup. From what I saw (I checked with a binary generated against
glibc and musl), on AMD64 we have enough space there to fit two
displaced stepping buffers. A subsequent patch makes AMD64/Linux use
two buffers.
In addition to having multiple displaced stepping buffers, there is also
the idea of sharing displaced stepping buffers between threads. Two
threads doing displaced steps for the same PC could use the same buffer
at the same time. Two threads stepping over the same instruction (same
opcode) at two different PCs may also be able to share a displaced
stepping buffer. This is an idea for future patches, but the
architecture built by this patch is made to allow this.
Now, the implementation details. The main part of this patch is moving
the responsibility of preparing and finishing a displaced step to the
gdbarch. Before this patch, preparing a displaced step is driven by the
displaced_step_prepare_throw function. It does some calls to the
gdbarch to do some low-level operations, but the high-level logic is
there. The steps are roughly:
- Ask the gdbarch for the displaced step buffer location
- Save the existing bytes in the displaced step buffer
- Ask the gdbarch to copy the instruction into the displaced step buffer
- Set the pc of the thread to the beginning of the displaced step buffer
Similarly, the "fixup" phase, executed after the instruction was
successfully single-stepped, is driven by the infrun code (function
displaced_step_finish). The steps are roughly:
- Restore the original bytes in the displaced stepping buffer
- Ask the gdbarch to fixup the instruction result (adjust the target's
registers or memory to do as if the instruction had been executed in
its original location)
The displaced_step_inferior_state::step_thread field indicates which
thread (if any) is currently using the displaced stepping buffer, so it
is used by displaced_step_prepare_throw to check if the displaced
stepping buffer is free to use or not.
This patch defers the whole task of preparing and cleaning up after a
displaced step to the gdbarch. Two new main gdbarch methods are added,
with the following semantics:
- gdbarch_displaced_step_prepare: Prepare for the given thread to
execute a displaced step of the instruction located at its current PC.
Upon return, everything should be ready for GDB to resume the thread
(with either a single step or continue, as indicated by
gdbarch_displaced_step_hw_singlestep) to make it displaced step the
instruction.
- gdbarch_displaced_step_finish: Called when the thread stopped after
having started a displaced step. Verify if the instruction was
executed, if so apply any fixup required to compensate for the fact
that the instruction was executed at a different place than its
original pc. Release any resources that were allocated for this
displaced step. Upon return, everything should be ready for GDB to
resume the thread in its "normal" code path.
The displaced_step_prepare_throw function now pretty much just offloads
to gdbarch_displaced_step_prepare and the displaced_step_finish function
offloads to gdbarch_displaced_step_finish.
The gdbarch_displaced_step_location method is now unnecessary, so is
removed. Indeed, the core of GDB doesn't know how many displaced step
buffers there are nor where they are.
To keep the existing behavior for existing architectures, the logic that
was previously implemented in infrun.c for preparing and finishing a
displaced step is moved to displaced-stepping.c, to the
displaced_step_buffer class. Architectures are modified to implement
the new gdbarch methods using this class. The behavior is not expected
to change.
The other important change (which arises from the above) is that the
core of GDB no longer prevents concurrent displaced steps. Before this
patch, start_step_over walks the global step over chain and tries to
initiate a step over (whether it is in-line or displaced). It follows
these rules:
- if an in-line step is in progress (in any inferior), don't start any
other step over
- if a displaced step is in progress for an inferior, don't start
another displaced step for that inferior
After starting a displaced step for a given inferior, it won't start
another displaced step for that inferior.
In the new code, start_step_over simply tries to initiate step overs for
all the threads in the list. But because threads may be added back to
the global list as it iterates the global list, trying to initiate step
overs, start_step_over now starts by stealing the global queue into a
local queue and iterates on the local queue. In the typical case, each
thread will either:
- have initiated a displaced step and be resumed
- have been added back by the global step over queue by
displaced_step_prepare_throw, because the gdbarch will have returned
that there aren't enough resources (i.e. buffers) to initiate a
displaced step for that thread
Lastly, if start_step_over initiates an in-line step, it stops
iterating, and moves back whatever remaining threads it had in its local
step over queue to the global step over queue.
Two other gdbarch methods are added, to handle some slightly annoying
corner cases. They feel awkwardly specific to these cases, but I don't
see any way around them:
- gdbarch_displaced_step_copy_insn_closure_by_addr: in
arm_pc_is_thumb, arm-tdep.c wants to get the closure for a given
buffer address.
- gdbarch_displaced_step_restore_all_in_ptid: when a process forks
(at least on Linux), the address space is copied. If some displaced
step buffers were in use at the time of the fork, we need to restore
the original bytes in the child's address space.
These two adjustments are also made in infrun.c:
- prepare_for_detach: there may be multiple threads doing displaced
steps when we detach, so wait until all of them are done
- handle_inferior_event: when we handle a fork event for a given
thread, it's possible that other threads are doing a displaced step at
the same time. Make sure to restore the displaced step buffer
contents in the child for them.

Many spots incorrectly use only spaces for indentation (for example,
there are a lot of spots in ada-lang.c). I've always found it awkward
when I needed to edit one of these spots: do I keep the original wrong
indentation, or do I fix it? What if the lines around it are also
wrong, do I fix them too? I probably don't want to fix them in the same
patch, to avoid adding noise to my patch.
So I propose to fix as much as possible once and for all (hopefully).
One typical counter argument for this is that it makes code archeology
more difficult, because git-blame will show this commit as the last
change for these lines. My counter counter argument is: when
git-blaming, you often need to do "blame the file at the parent commit"
anyway, to go past some other refactor that touched the line you are
interested in, but is not the change you are looking for. So you
already need a somewhat efficient way to do this.
Using some interactive tool, rather than plain git-blame, makes this
trivial. For example, I use "tig blame <file>", where going back past
the commit that changed the currently selected line is one keystroke.
It looks like Magit in Emacs does it too (though I've never used it).
Web viewers of Github and Gitlab do it too. My point is that it won't
really make archeology more difficult.
The other typical counter argument is that it will cause conflicts with
existing patches. That's true... but it's a one time cost, and those
are not conflicts that are difficult to resolve. I have also tried "git
rebase --ignore-whitespace", it seems to work well. Although that will
re-introduce the faulty indentation, so one needs to take care of fixing
the indentation in the patch after that (which is easy).

I'd like to enable the -Wmissing-declarations warning. However, it
warns for every _initialize function, for example:
CXX dcache.o
/home/smarchi/src/binutils-gdb/gdb/dcache.c: In function ‘void _initialize_dcache()’:
/home/smarchi/src/binutils-gdb/gdb/dcache.c:688:1: error: no previous declaration for ‘void _initialize_dcache()’ [-Werror=missing-declarations]
_initialize_dcache (void)
^~~~~~~~~~~~~~~~~~
The only practical way forward I found is to add back the declarations,
which were removed by this commit:
commit 481695ed5f6e0a8a9c9c50bfac1cdd2b3151e6c9
Author: John Baldwin <jhb@FreeBSD.org>
Date: Sat Sep 9 11:02:37 2017 -0700
Remove unnecessary function prototypes.
I don't think it's a big problem to have the declarations for these
functions, but if anybody has a better solution for this, I'll be happy
to use it.

gdb/ChangeLog:
Update copyright year range in all GDB files.
|
|
This is the next patch in the ongoing series to move gdbsever to the
top level.
This patch just renames the "common" directory. The idea is to do
this move in two parts: first rename the directory (this patch), then
move the directory to the top. This approach makes the patches a bit
more tractable.
I chose the name "gdbsupport" for the directory. However, as this
patch was largely written by sed, we could pick a new name without too
much difficulty.
Tested by the buildbot.

Both the i386, X86_64 and AArch64 builds of gdbserver include a bunch of legacy
xml files, dat files and auto generated C files, when building for unit test.
These tests exists back from when feature target descriptions were added to
prove that the new target descriptions were identical to the original
older versions. The old files are not used for anything other than these tests.
Now that this has been proven, we are not gaining anything by keeping the
original files and tests. Should new functionality be added, it would break
the tests, unless the functionality was backported to the xml. There is no
requirement that we must match the exact xml from N releases ago. It adds
obfuscation, where as the feature target descriptions were meant to simplify
the code.
In addition, there are a bunch of xml and dat files which are completely unused.
This patch removes the selftests and the target descriptions from gdbserver.
Update the unittest to allow 0 tests (note, this failed on other targets that
never had any tests).

Andreas Schwab and John Baldwin pointed out some bugs in the header
sorting patch; and I noticed that the output was not correct when
limited to a subset of files (a bug in my script).
So, I'm reverting the patch. I may try again after fixing the issues
pointed out.

This makes a new base class, expr_builder, for parser_state. This
separates the state needed to construct an expression from the state
needed by the parsers.

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.

In the existing code, when using the regset section iteration functions, the
size parameter is used in different ways.
With collect, size is used to create the buffer in which to write the regset.
(see linux-tdep.c::linux_collect_regset_section_cb).
With supply, size is used to confirm the existing regset is the correct size.
If REGSET_VARIABLE_SIZE is set then the regset can be bigger than size.
Effectively, size is the minimum possible size of the regset.
(see corelow.c::get_core_register_section).
There are currently no targets with both REGSET_VARIABLE_SIZE and a collect
function.
In SVE, a corefile can contain one of two formats after the header, both of
which are different sizes. However, when writing a core file, we always want
to write out the full bigger size.
To allow support of collects for REGSET_VARIABLE_SIZE we need two sizes.

GDB is currently crashing anytime we try to access the fs_base/gs_base
registers, either to read them, or to write them. This can be observed
under various scenarios:
- Explicit reference to those registers (eg: print $fs_base) --
probably relatively rare;
- Calling a function in the inferior, with the crash happening
because we are trying to read those registers in order to save
their value ahead of making the function call;
- Just a plain "info registers";
The crash was introduced by the following commit:
| commit 48aeef91c248291dd03583798904612426b1f40a
| Date: Mon Jun 26 18:14:43 2017 -0700
| Subject: Include the fs_base and gs_base registers in amd64 target descriptions.
The Windows-nat implementation was unfortunately not prepared to deal
with those new registers. In particular, the way it fetches registers
is done by using a table where the index is the register number, and
the value at that index is the offset in the area in the thread's CONTEXT
data where the corresponding register value is stored.
For instance, in amd64-windows-nat.c, we can find the mappings static
array containing the following 57 elements in it:
#define context_offset(x) (offsetof (CONTEXT, x))
static const int mappings[] =
{
context_offset (Rax),
[...]
context_offset (FloatSave.MxCsr)
};
That array is then used by windows_fetch_one_register via:
char *context_offset = ((char *) &th->context) + mappings[r];
The problem is that fs_base's register number is 172, which is
well past the end of the mappings array (57 elements in total).
We end up getting an undefined offset, which happens to be so large
that it then causes the address where we try to read the register
value (a little bit later) to be invalid, thus crashing GDB with
a SEGV.
This patch side-steps the issue entirely by removing support for
those registers in GDB on x86_64-windows, because a look at the
CONTEXT structure indicates no support for getting those registers.
A more comprehensive fix would patch the potential buffer overflow
of the mappings array, but this can be done as a separate commit.

This is more preparation bits for multi-target support.
In a multi-target scenario, we need to address the case of different
processes/threads running on different targets that happen to have the
same PID/PTID. E.g., we can have both process 123 in target 1, and
process 123 in target 2, while they're in reality different processes
running on different machines. Or maybe we've loaded multiple
instances of the same core file. Etc.
To address this, in my WIP multi-target branch, threads and processes
are uniquely identified by the (process_stratum target_ops *, ptid_t)
and (process_stratum target_ops *, pid) tuples respectively. I.e.,
each process_stratum instance has its own thread/process number space.
As you can imagine, that requires passing around target_ops * pointers
in a number of functions where we're currently passing only a ptid_t
or an int. E.g., when we look up a thread_info object by ptid_t in
find_thread_ptid, the ptid_t alone isn't sufficient.
In many cases though, we already have the thread_info or inferior
pointer handy, but we "lose" it somewhere along the call stack, only
to look it up again by ptid_t/pid. Since thread_info or inferior
objects know their parent target, if we pass around thread_info or
inferior pointers when possible, we avoid having to add extra
target_ops parameters to many functions, and also, we eliminate a
number of by ptid_t/int lookups.
So that's what this patch does. In a bit more detail:
- Changes a number of functions and methods to take a thread_info or
inferior pointer instead of a ptid_t or int parameter.
- Changes a number of structure fields from ptid_t/int to inferior or
thread_info pointers.
- Uses the inferior_thread() function whenever possible instead of
inferior_ptid.
- Uses thread_info pointers directly when possible instead of the
is_running/is_stopped etc. routines that require a lookup.
- A number of functions are eliminated along the way, such as:
int valid_gdb_inferior_id (int num);
int pid_to_gdb_inferior_id (int pid);
int gdb_inferior_id_to_pid (int num);
int in_inferior_list (int pid);
- A few structures and places hold a thread_info pointer across
inferior execution, so now they take a strong reference to the
(refcounted) thread_info object to avoid the thread_info pointer
getting stale. This is done in enable_thread_stack_temporaries and
in the infcall.c code.
- Related, there's a spot in infcall.c where using a RAII object to
handle the refcount would be handy, so a gdb::ref_ptr specialization
for thread_info is added (thread_info_ref, in gdbthread.h), along
with a gdb_ref_ptr policy that works for all refcounted_object types
(in common/refcounted-object.h).

When compiling with clang 6, I see a bunch of warnings like this:
/home/emaisin/src/binutils-gdb/gdb/amd64-linux-tdep.c:1427:8: error: comparison of two values with different enumeration types in switch statement ('enum amd64_syscall' and 'amd
64_x32_syscall') [-Werror,-Wenum-compare-switch]
case amd64_x32_sys_move_pages:
^~~~~~~~~~~~~~~~~~~~~~~~
In this switch, we indeed use enumerators of both types
amd64_x32_syscall and amd64_syscall. This is done on purpose, and the
enum values are chosen so that they are complementary.
I think it's still a useful warning, so I chose to ignore just that
particular case.

As an update to commit ede5f15146ae ("gdbarch.h: Change
gdbarch_info::tdep_info's type to void *") replace the definition of the
`tdep_info' member in `struct gdbarch_info' with an anonymous union,
comprising the original member, with its type reverted to `struct
gdbarch_tdep_info *', a `tdesc_data' member of a `struct tdesc_arch_data
*' type and an `id' member of an `int *' type. Remove now unnecessary
casts throughout use places then, making code easier to read an less
prone to errors, which may happen with casting.

The direct cause of the crash is that we tried to remove an element
from the hash which supposedly exists, but does not. (htab_remove_elt
shouldn't really crash in this case, but that's secondary.)
The real problem is that early_data passed to tdesc_use_registers
includes regs from a target description that is not the target_desc,
which violates its assumptions. The registers in question are the
fs_base/gs_base registers, added by amd64_init_abi:
tdesc_numbered_register (feature, tdesc_data_segments,
AMD64_FSBASE_REGNUM, "fs_base");
tdesc_numbered_register (feature, tdesc_data_segments,
AMD64_GSBASE_REGNUM, "gs_base");
and that happens because amd64_linux_init_abi uses amd64_init_abi as
helper, but they don't coordinate on which fallback tdesc to use.
amd64_init_abi does:
if (! tdesc_has_registers (tdesc))
tdesc = tdesc_amd64;
and then adds the fs_base/gs_base registers of the "tdesc_amd64" tdesc
to the tdesc_arch_data.
After amd64_init_abi returns, amd64_linux_init_abi does:
if (! tdesc_has_registers (tdesc))
tdesc = tdesc_amd64_linux;
tdep->tdesc = tdesc;
and we end up tdesc_amd64_linux installed in tdep->tdesc.
The fix is to make sure that amd64_linux_init_abi and amd64_init_abi
agree on default tdesc, by adding a "default tdesc" parameter to
amd64_init_abi, instead of having amd64_init_abi hardcode a default.
With this, amd64_init_abi creates the fs_base/gs_base registers using
the tdesc_amd64_linux tdesc.
Tested on x86-64 GNU/Linux, -m64. I don't have an x32 setup handy.
Thanks to John Baldwin, Yao Qi and Simon Marchi for the investigation.

The displaced_step_free_closure gdbarch hook allows architectures to
free data they might have allocated to complete a displaced step.
However, all architectures using that hook use the
simple_displaced_step_free_closure provided in arch-utils.{c,h}, which
does a simple xfree. We can remove it and do an xfree directly instead
of calling the hook.
gdb/ChangeLog:
* gdbarch.sh (displaced_step_free_closure): Remove.
* gdbarch.h, gdbarch.c: Re-generate.
* aarch64-linux-tdep.c (aarch64_linux_init_abi): Don't set

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.
