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.

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.

The problem is a type/width mismatch in code like this, in
gdbserver/i387-fp.c:
/* Some registers are 16-bit. */
collect_register_by_name (regcache, "fctrl", &val);
fp->fctrl = val;
In the above code:
#1 - 'val' is a 64-bit unsigned long.
#2 - "fctrl" is 32-bit in the register cache, thus half of 'val' is
left uninitialized by collect_register_by_name, which works with
an untyped raw buffer output (i.e., void*).
#3 - fp->fctrl is an unsigned short (16-bit). For some such
registers we're masking off the uninitialized bits with 0xffff,
but not in all cases.
We end up in such a fragile situation because
collect_registers_by_name works with an untyped output buffer pointer,
making it easy to pass a pointer to a variable of the wrong size.
Fix this by using regcache_raw_get_unsigned instead (actually a new
regcache_raw_get_unsigned_by_name wrapper), which always returns a
zero-extended ULONGEST register value. It ends up simplifying the
i387-tdep.c code a bit, even.

For GNU/Linux on x86-64, if the target is using the xsave format for
passing the floating-point information from the inferior then there
currently exists a bug relating to the x87 control registers, and the
mxcsr register.
The xsave format allows different floating-point features to be lazily
enabled, a bit in the xsave format tells GDB which floating-point
features have been enabled, and which have not.
Currently in GDB, when reading the floating point state, we check the
xsave bit flags, if the feature is enabled then we read the feature
from the xsave buffer, and if the feature is not enabled, then we
supply the default value from within GDB.
Within GDB, when writing the floating point state, we first fetch the
xsave state from the target and then, for any feature that is not yet
enabled, we write the default values into the xsave buffer. Next we
compare the regcache value with the value in the xsave buffer, and, if
the value has changed we update the value in the xsave buffer, and
mark the feature enabled in the xsave bit flags.
The problem then, is that the x87 control registers were not following
this pattern. We assumed that these registers were always written out
by the kernel, and we always wrote them out to the xsave buffer (but
didn't enabled the feature). The result of this is that if the kernel
had not yet enabled the x87 feature then within GDB we would see
random values for the x87 floating point control registers, and if the
user tried to modify one of these register, that modification would be
lost.
Finally, the mxcsr register was also broken in the same way as the x87
control registers. The added complexity with this case is that the
mxcsr register is part of both the avx and sse floating point feature
set. When reading or writing this register we need to check that at
least one of these features is enabled.
This bug was present in native GDB, and within gdbserver. Both are
fixed with this commit.

This patch removes some unused variables, found with -Wunused. I have
not removed everything reported by -Wunused, because some expressions
such as
struct type *arg_type = check_typedef (value_type);
in bfin-tdep.c could have an unexpected but important side-effect. I
removed others that I considered more low-risk, such as:
struct gdbarch *gdbarch = get_objfile_arch (objfile);
I tested building with Python 2/Python 3/no Python, with/without expat,

Remove the usage of inferior_list for the all_threads list in
gdbserver. The entry field in thread_info is removed, and replaced by a
simple ptid field.
I added some functions to iterate (for_each_thread) and find threads
(find_thread). However, changing all the users of find_inferior & co to
use these new functions would have made the patch way too big. So I
opted instead to make find_inferior & co some shims, so that the
existing code only needs to be updated minimally. We can then update
the existing code to use the new functions incrementally (I've started
to do the work, but I'll post it afterwards, see [1] if you want a peek).
This patch has been built-tested on all relevant platforms, except
lynx. I also regtested using the native-gdbserver and
native-extended-gdbserver boards on x86.

This is a followup patch to the build breakage fix on AArch64. While
doing the fix, I found it better to convert tdesc->reg_defs (on
gdbserver/tdesc.h) from using VEC to using std::vector. This makes
the code easier to read and maintain, and also is one more step
towards the C++fication.
Regtested on BuildBot.

__warn_memset_zero_len ();
This is likely due to a GCC bug, because for some reason the compiler
assumes that the third argument to the memset:
memset (regcache->register_status, REG_UNAVAILABLE,
VEC_length (tdesc_reg_p, regcache->tdesc->reg_defs));
is always zero, which is not always true.
Anyway, the simple fix for this is to guard the memset calls with:
if (!VEC_empty (tdesc_reg_p, regcache->tdesc->reg_defs))
This time, I made sure to regtest only this patch on BuildBot, and it
finally solved the breakage.

Nowadays, target_desc.reg_defs is a pointer points to a pre-generated
array, which is not flexible. This patch changes it from an array
to a VEC so that GDBserver can create target descriptions dynamically
later. Instead of using pre-generated array, the -generated.c calls
VEC_safe_push to add each register to vector.
Since target_desc.reg_defs is used in IPA, we need to build common/vec.c
for IPA too.

These functions apply to thread, and not inferiors (in the gdbserver
sense, the abstraction for threads and processes, as in
inferior_list). Therefore, it would make more sense if these functions

This applies the second part of GDB's End of Year Procedure, which

gdb/ChangeLog:
Update copyright year range in all GDB files.

We have function regcache_raw_read_unsigned defined in both GDB and
GDBserver, so that it is used in common like this,
ULONGEST value;
status = regcache_raw_read_unsigned (regcache, regnum, &value);
'value' is correctly set in GDB side, but may not be correctly set
in GDBserver, because &value is passed in regcache_raw_read_unsigned
but collect_register may only set part of the whole variable. In my
test, I see the top half of 'value' is garbage. This patch fixes this
problem by clearing *VAL before calling collect_register.

This patch is in preparation for software single step support on ARM in
GDBServer. It adds a new shared function regcache_raw_read_unsigned and
regcache_raw_get_unsigned so that GDB and GDBServer can use the same call
to fetch a raw register into an integer.
No regressions, tested on ubuntu 14.04 ARMv7 and x86.

This crash is observable by debugging a threaded program on LynxOS.
On the GDB side, this is what we would see:
% gdb q
(gdb) target remote machine:4444
(gdb) break q.adb:6
(gdb) cont
[gdb hits breakpoint]
(gdb) cont
Remote connection closed <<<--- expected: [Inferior 1 (Remote target) exited normally]
On the gdbserver side, which was launched as usual:
% gdbserver --once :4444 q
Segmentation fault (core dumped)
Ooops!
The problem happens while GDB is trying to handle the thread termination
event of the thread that hit the breakpoint. It started happening after
the following change was made:
commit 96e7a1eb6d09fda9e22e112e35e7d0085a8f4fd0
Date: Fri Oct 16 11:08:38 2015 -0400
Subject: gdbserver: Reset current_thread when the thread is removed.
Reset current_thread and make sure 'remove_process' is used
after all associated threads have been removed first.
More precisely:
. GDBserver receives the execution-resume order;
. lynx-low resumes it succesfully, and then relies on lynx_wait_1
to wait for the next event;
. We quickly receive one, which lynx_wait_1 analyzes to be
a "thread exit" event, and therefore does...
case SIGTHREADEXIT:
remove_thread (find_thread_ptid (new_ptid));
lynx_continue (new_ptid);
goto retry;
=> remove_thread causes current_thread to be set to NULL...
(that's the recent change mentioned above)
=> ... which causes problems during lynx_continue, because
it calls lynx_resume, which calls regcache_invalidate,
which unfortunately assumes that CURRENT_THREAD is not NULL:
void
regcache_invalidate (void)
{
/* Only update the threads of the current process. */
SEGV!--> int pid = ptid_get_pid (current_thread->entry.id);
find_inferior (&all_threads, regcache_invalidate_one, &pid);
}
Since the problem at hand is caused by trying to figure out which
inferior to reset the regcache for, and since lynx_resume actually
had that info, this patch fixes the problem by introducing a new
routine called regcache_invalidate_pid, which invalidates the cache
of the given pid; and then modifies lynx_resume use that new routine
rather than relying on regcache_invalidate to invalidate the regcache
of the expected inferior.
gdb/gdbserver/ChangeLog:
* regcache.h (regcache_invalidate_pid): Add declaration.
* regcache.c (regcache_invalidate_pid): New function, extracted
from regcache_invalidate.
(regcache_invalidate): Reimplement using regcache_invalidate_pid.
Add trivial documentation comment.
* lynx-low.c: Use regcache_invalidate_pid instead of
regcache_invalidate.

Nowadays, both aarch64 GDB and linux kernel assumes that address for
setting breakpoint should be 4-byte aligned. However that is not true
after we support multi-arch, because thumb instruction can be at 2-byte
aligned address. Patch http://lists.infradead.org/pipermail/linux-arm-kernel/2015-October/375141.html
to linux kernel is to teach kernel to handle 2-byte aligned address for
HW breakpoint, while this patch is to teach aarch64 GDB handle 2-byte
aligned address.
First of all, we call gdbarch_breakpoint_from_pc to get the instruction
length rather than using hard-coded 4. Secondly, in GDBserver, we set
length back to 2 if it is 3, because GDB encode 3 in it to indicate it
is a 32-bit thumb breakpoint. Then we relax the address alignment
check from 4-byte aligned to 2-byte aligned.
This patch enables some tests (such as gdb.base/break-idempotent.exp,
gdb.base/cond-eval-mode.exp, gdb.base/watchpoint-reuse-slot.exp,) and
fixes many fails (such as gdb.base/hbreak2.exp) when the program is
compiled in thumb mode on aarch64.
Regression tested on aarch64-linux, both native and gdbserver. This
is the last patch of multi-arch work.

Most allocation functions (if not all) return a void* pointing to the
allocated memory. In C++, we need to add an explicit cast when
assigning the result to a pointer to another type (which is the case
more often than not).
The content of this patch is taken from Pedro's branch, from commit
"(mostly) auto-generated patch to insert casts needed for C++". I
validated that the changes make sense and manually reflowed the code to
make it respect the coding style. I also found multiple places where I
could use XNEW/XNEWVEC/XRESIZEVEC/etc.
Thanks a lot to whoever did that automated script to insert casts, doing
it completely by hand would have taken a ridiculous amount of time.
Only files built on x86 with --enable-targets=all are modified. This
means that all other -nat.c files are untouched and will have to be
dealt with later by using appropiate compilers. Or maybe we can try to
build them with a regular g++ just to know where to add casts, I don't
know.
I built-tested this with --enable-targets=all and reg-tested.
Here's the changelog entry, which was not too bad to make despite the
size, thanks to David Malcom's script. I fixed some bits by hand, but
there might be some wrong parts left (hopefully not).

This patch is part of the make-gdb-buildable-in-C++ effort. The idea is
to change some calls to the xmalloc family of functions to calls to the
equivalents in the XNEW family. This avoids adding an explicit cast, so
it keeps the code a bit more readable. Some of them also map relatively
well to a C++ equivalent (XNEW (struct foo) -> new foo), so it will be
possible to do scripted replacements if needed.
I only changed calls that were obviously allocating memory for one or
multiple "objects". Allocation of variable sizes (such as strings or
buffer handling) will be for later (and won't use XNEW).
- xmalloc (sizeof (struct foo)) -> XNEW (struct foo)
- xmalloc (num * sizeof (struct foo)) -> XNEWVEC (struct foo, num)
- xcalloc (1, sizeof (struct foo)) -> XCNEW (struct foo)
- xcalloc (num, sizeof (struct foo)) -> XCNEWVEC (struct foo, num)
- xrealloc (p, num * sizeof (struct foo) -> XRESIZEVEC (struct foo, p, num)
- obstack_alloc (ob, sizeof (struct foo)) -> XOBNEW (ob, struct foo)
- obstack_alloc (ob, num * sizeof (struct foo)) -> XOBNEWVEC (ob, struct foo, num)
- alloca (sizeof (struct foo)) -> XALLOCA (struct foo)
- alloca (num * sizeof (struct foo)) -> XALLOCAVEC (struct foo, num)
Some instances of xmalloc followed by memset to zero the buffer were
replaced by XCNEW or XCNEWVEC.
I regtested on x86-64, Ubuntu 14.04, but the patch touches many
architecture-specific files. For those I'll have to rely on the
buildbot or people complaining that I broke their gdb.

The regcache used to be hidden inside inferiors.c, but since the
tracepoints support that it's a first class object. This also fixes a
few implicit pointer conversion errors in C++ mode, caused by a few
places missing the explicit cast.
gdb/gdbserver/ChangeLog:

pointer.

Update year range in copyright notice of all files.

When fetch_inferior_registers does not update all registers, this
patch assures that no stale register values remain in the register
cache. On Linux platforms using the regsets interface, when one of
the ptrace calls used for fetching the register values returns an
error, this patch also avoids copying the random data returned from
ptrace into the register cache. All unfetched registers are marked
"unavailable" instead.
gdb/gdbserver/ChangeLog:
* linux-low.c (regsets_fetch_inferior_registers): Do not invoke
the regset's store function when ptrace returned an error.
* regcache.c (get_thread_regcache): Invalidate register cache
before fetching inferior's registers.

GDB has a function named "current_inferior" and gdbserver has a global
variable named "current_inferior", but the two are not equivalent;
indeed, gdbserver does not have any real equivalent of what GDB calls
an inferior. What gdbserver's "current_inferior" is actually pointing
to is a structure describing the current thread. This commit renames
current_inferior as current_thread in gdbserver to clarify this. It
also renames the function "set_desired_inferior" to "set_desired_thread"
and renames various local variables from foo_inferior to foo_thread.
gdb/gdbserver/ChangeLog:
* inferiors.h (current_inferior): Renamed as...

This introduces common-regcache.h. This contains two functions that
allow nat/linux-btrace.c to be simplified. A better long term
solution would be unify the regcache code, but this is sufficient for
now.

convert_int_to_ascii is identical to bin2hex. This removes the
former. In this case I made the choice of which to keep on the basis

This moves various low-level remote serial protocol bits into
common/rsp-low.[ch].
This is as close to a pure move as possible. There are some
redundancies remaining but those will be dealt with in a subsequent
patch.
Note that the two variants of remote_escape_output disagreed on the
treatment of "*". On the theory that quoting cannot hurt but the
absence possibly can, I chose the gdbserver variant to be the
canonical one.

This patch makes GDBserver support multi-process + biarch.
Currently, if you're debugging more than one process at once with a
single gdbserver (in extended-remote mode), then all processes must
have the same architecture (e.g., 64-bit vs 32-bit). Otherwise, you
see this:

... etc, etc ...
Even though the process was running a 32-bit program, GDBserver sent
back to GDB a register set in 64-bit layout.
A patch (http://sourceware.org/ml/gdb-patches/2012-11/msg00228.html) a
while ago made GDB track a target_gdbarch per inferior, and as
consequence, fetch a target description per-inferior. This patch is
the GDBserver counterpart, that makes GDBserver keep track of each
process'es XML target description and register layout. So in the
example above, GDBserver will send the correct register set in 32-bit
layout to GDB.
A new "struct target_desc" object (tdesc for short) is added, that
holds the target description and register layout information about
each process. Each `struct process_info' holds a pointer to a target
description. The regcache also gains a pointer to a target
description, mainly for convenience, and parallel with GDB (and
possible future support for programs that flip processor modes).
The low target's arch_setup routines are responsible for setting the
process'es correct tdesc. This isn't that much different to how
things were done before, except that instead of detecting the inferior
process'es architecture and calling the corresponding
init_registers_FOO routine, which would change the regcache layout
globals and recreate the threads' regcaches, the regcache.c globals
are gone, and the init_registers_$BAR routines now each initialize a
separate global struct target_desc object (one for each arch variant
GDBserver supports), and so all the init_registers_$BAR routines that
are built into GDBserver are called early at GDBserver startup time
(similarly to how GDB handles its built-in target descriptions), and
then the arch_setup routine is responsible for making
process_info->tdesc point to one of these target description globals.
The regcache module is all parameterized to get the regcache's layout
from the tdesc object instead of the old register_bytes, etc. globals.
The threads' regcaches are now created lazily. The old scheme where
we created each of them when we added a new thread doesn't work
anymore, because we add the main thread/lwp before we see it stop for
the first time, and it is only when we see the thread stop for the
first time that we have a chance of determining the inferior's
architecture (through the_low_target.arch_setup). Therefore when we
add the main thread we don't know which architecture/tdesc its
regcache should have.
This patch makes the gdb.multi/multi-arch.exp test now pass against
(extended-remote) GDBserver. It currently fails, without this patch.
The IPA also uses the regcache, so it gains a new global struct
target_desc pointer, which points at the description of the process it
is loaded in.
Re. the linux-low.c & friends changes. Since the register map
etc. may differ between processes (64-bit vs 32-bit) etc., the
linux_target_ops num_regs, regmap and regset_bitmap data fields are no
longer sufficient. A new method is added in their place that returns
a pointer to a new struct that includes all info linux-low.c needs to
access registers of the current inferior.
The patch/discussion that originally introduced
linux-low.c:disabled_regsets mentions that the disabled_regsets set
may be different per mode (in a biarch setup), and indeed that is
cleared whenever we start a new (first) inferior, so that global is
moved as well behind the new `struct regs_info'.
On the x86 side:
I simply replaced the i387-fp.c:num_xmm_registers global with a check
for 64-bit or 32-bit process, which is equivalent to how the global
was set. This avoided coming up with some more general mechanism that
would work for all targets that use this module (GNU/Linux, Windows,
etc.).
