This commit is the result of running the gdb/copyright.py script,
which automated the update of the copyright year range for all
source files managed by the GDB project to be updated to include
year 2023.
This changes windows_process_info to use virtual methods for its
callbacks, and then changes the two clients of this code to subclass
this class to implement the methods.
I considered using CRTP here, but that would require making the new
structures visible to the compilation of of nat/windows-nat.c. This
seemed like a bit of a pain, so I didn't do it.
This change then lets us change all the per-inferior globals to be
members of the new subclass. Note that there can still only be a
single inferior -- currently there's a single global of the new type.
This is just another step toward possibly implementing multi-inferior
for Windows.
It's possible this could be cleaned up further... ideally I'd like to
move more of the data into the base class. However, because gdb
supports Cygwin and gdbserver does not, and because I don't have a way
to build or test Cygwin, larger refactorings are difficult.
On Windows, it is possible to disable ASLR when creating a process.
This patch adds code to do this, and hooks it up to gdb's existing
disable-randomization feature. Because the Windows documentation
cautions that this isn't available on all versions of Windows, the
CreateProcess wrapper function is updated to make the attempt, and
then fall back to the current approach if it fails.
I noticed that gdbserver did not implement pid_to_exec_file for
Windows, while gdb did implement it. This patch moves the code to
nat/windows-nat.c, so that it can be shared. This makes the gdbserver
implementation trivial.
I noticed a few spots in GDB that use "typedef enum". However, in C++
this isn't as useful, as the tag is automatically entered as a
typedef. This patch removes most uses of "typedef enum" -- the
exceptions being in some nat-* code I can't compile, and
glibc_thread_db.h, which I think is more or less a copy of some C code
from elsewhere.
Tested by rebuilding.
Windows 10 introduced SetThreadDescription and GetThreadDescription, a
simpler way to set a thread's name. This changes gdb and gdbserver to
use this convention when it is available.
This is part of PR win32/29050.
Bug: https://sourceware.org/bugzilla/show_bug.cgi?id=29050
Currently, gdb's native Windows target implements the exception-based
approach for setting thread names, but gdbserver does not. This patch
moves handle_ms_vc_exception to the shared nat/windows-nat.c code, as
preparation for adding this support to gdbserver.
nat/windows-nat.c has a number of globals that it uses to communicate
with its clients (gdb and gdbserver). However, if we ever want the
Windows ports to be multi-inferior, globals won't work.
This patch takes a step toward that by moving most nat/windows-nat.c
globals into a new struct windows_process_info. Many functions are
converted to be methods on this object.
A couple of globals remain, as they are needed to truly be global due
to the way that the Windows debugging APIs work.
The clients still have a global for the current process. That is,
this patch is a step toward the end goal, but doesn't implement the
goal itself.
This commit brings all the changes made by running gdb/copyright.py
as per GDB's Start of New Year Procedure.
For the avoidance of doubt, all changes in this commits were
performed by the script.
The only callers of get_image_name are nat/windows-nat.c, so make it
static.

This moves the new DLL-loading code into nat/windows-nat.c, and

nat/windows-nat.c; maybe I had planned to share more here and then
didn't finish... I'm not sure.

The support for WinCE was removed with commit 84b300de3666 ("gdbserver:
remove support for ARM/WinCE"). There is some leftover code for WinCE
support, guarded by the _WIN32_WCE macro, which I didn't know of at the
time.
I didn't remove the _WIN32_WCE references in the tests, because in
theory we still support the WinCE architecture in GDB (when debugging
remotely). So someone could run a test with that (although I'd be
really surprised).

gdb/ChangeLog
Update copyright year range in copyright header of all GDB files.
When a WOW64 process triggers a breakpoint exception in 64bit code (which
happens when a 64bit gdb calls DebugBreakProcess for a 32bit target),
gdb ignores the breakpoint (because Wow64GetThreadContext can only report
the pc of 32bit code, and there is not int3 at this location).
But if these 64bit breakpoint exceptions are handled as SIGINT, gdb
doesn't check for int3, and always stops the target.
gdb/ChangeLog:
2020-09-23 Hannes Domani <ssbssa@yahoo.de>
* nat/windows-nat.c (handle_exception): Handle 64bit breakpoints

Writing to inferior_ptid in
windows_nat_target::get_windows_debug_event is just incorrect and not
necessary. We'll report the event to GDB's core, which then takes
care of switching inferior_ptid / current thread.
Related (see windows_nat_target::get_windows_debug_event), there's
also a "current_windows_thread" global that is just begging to get out
of sync with core GDB's current thread. This patch removes it.
gdbserver already does not have an equivalent global in win32-low.cc.

(windows_nat_target::create_inferior): Adjust.
The updated pending stop series introduced a regression in Windows
debugging. When stopped at a software breakpoint, we would adjust the
PC each time it was requested -- however, more than a single
adjustment is incorrect. This patch introduces a new flag that is
used to ensure the adjustment only happens a single time.
No similar change is needed in gdbserver, because it adjusts the PC in
a different way.
I still can't run the gdb test suite on Windows, but I can run the
internal AdaCore test suite there; and this fixes the regressions
there.

Simon pointed out that the windows-nat sharing series broke the Cygwin

gdbserver.

Both gdb and gdbserver have a "handle_exception" function, the bulk of

This changes nat/windows-nat.h to declare handle_load_dll and

PR gdb/22992 concerns an assertion failure in gdb when debugging a
certain inferior:
int finish_step_over(execution_control_state*): Assertion `ecs->event_thread->control.trap_expected' failed.
Initially the investigation centered on the discovery that gdb was not
suspending other threads when attempting to single-step. This
oversight is corrected in this patch: now, when stepping a thread, gdb
will call SuspendThread on all other threads.
However, the bug persisted even after this change. In particular,
WaitForDebugEvent could see a stop for a thread that was ostensibly
suspended. Our theory of what is happening here is that there are
actually simultaneous breakpoint hits, and the Windows kernel queues
the events, causing the second stop to be reported on a suspended
thread.
In Windows 10 or later gdb could use the DBG_REPLY_LATER flag to
ContinueDebugEvent to request that such events be re-reported later.
However, relying on that did not seem advisable, so this patch instead
arranges to queue such "pending" stops, and then to report them later,
once the step has completed.
In the PR, Pedro pointed out that it's best in this scenario to
implement the stopped_by_sw_breakpoint method, so this patch does this
as well.

Note that the two implementations different slightly. gdb had a
couple of fields ("name" and "reload_context") that gdbserver did not;
while gdbserver had one field ("base_context") that gdb did not, plus
better comments. The new file preserves all the fields, and the
comments.
