The starting point was PR gdb/26877:

The first two patches are preparatory.  The main patch is the last one.

[PATCH 1/3] gdb/testsuite: update the expected output in gdb.threads/killed-outside.exp

[Tankut Baris Aktemur]

When running the gdb.threads/killed-outside.exp test using the
native-gdbserver and native-extended-gdbserver boards, we get

  ...
  FAIL: gdb.threads/killed-outside.exp: prompt after first continue
  ...

Update the expected output to also consider the cases seen when using
those two boards.

[PATCH 2/3] gdb/regcache: return REG_UNAVAILABLE if raw_update raises NOT_AVAILABLE_ERROR

[Tankut Baris Aktemur]

In regcache's raw_read, it is possible that 'raw_update' fails with an
exception.  Catch this exception and return REG_UNAVAILABLE if the
error is of kind NOT_AVAILABLE_ERROR.  This makes clients' lives easier.

Regression-tested on X86_64-Linux.

    gdb/infrun: handle already-exited threads when attempting to stop

If a process dies before GDB reports the exit error to the user, we
may see the "Couldn't get registers: No such process." error message
in various places.  For instance:

  (gdb) start
  ...
  (gdb) shell kill -9 31943
  (gdb) flushregs
  Register cache flushed.
  Couldn't get registers: No such process.
  (gdb) info threads
    Id   Target Id              Frame
  * 1    process 31943 "a.out" Couldn't get registers: No such process.
  Couldn't get registers: No such process.
  (gdb) backtrace
  Python Exception <class 'gdb.error'> Couldn't get registers: No such process.:
  Couldn't get registers: No such process.
  (gdb) inferior 1
  Couldn't get registers: No such process.
  (gdb) thread
  [Current thread is 1 (process 31943)]
  Couldn't get registers: No such process.
  (gdb)

The gdb.threads/killed-outside.exp, gdb.multi/multi-kill.exp, and
gdb.multi/multi-exit.exp tests also check related scenarios.

To improve the situation,

1. when printing the frame info, catch and process a NOT_AVAILABLE_ERROR.

2. when accessing the target to fetch registers, if the operation
   fails, raise a NOT_AVAILABLE_ERROR instead of a generic error, so
   that clients can attempt to recover accordingly.  This patch updates
   the amd64_linux_nat_target and remote_target in this direction.

With this patch, we obtain the following behavior:

  (gdb) start
  ...
  (gdb) shell kill -9 3412
  (gdb) flushregs
  Register cache flushed.
  (gdb) info threads
    Id   Target Id             Frame
  * 1    process 3412 "a.out" <PC register is not available>
  (gdb) backtrace
  #0  <PC register is not available>
  Backtrace stopped: not enough registers or memory available to unwind further
  (gdb) inferior 1
  [Switching to inferior 1 [process 3412] (/path/to/a.out)]
  [Switching to thread 1 (process 3412)]
  #0  <PC register is not available>
  (gdb) thread
  [Current thread is 1 (process 3412)]
  (gdb)

Here is another "before/after" case.  Suppose we have two inferiors,
each having its own remote target underneath.  Before this patch, we
get the following output:

  # Create two inferiors on two remote targets, resume both until
  # termination.  Exit event from one of them is shown first, but the
  # other also exited -- just not yet shown.
  (gdb) maint set target-non-stop on
  (gdb) target remote | gdbserver - ./a.out
  (gdb) add-inferior -no-connection
  (gdb) inferior 2
  (gdb) target remote | gdbserver - ./a.out
  (gdb) set schedule-multiple on
  (gdb) continue
  ...
  [Inferior 2 (process 22127) exited normally]
  (gdb) inferior 1
  [Switching to inferior 1 [process 22111] (target:/path/to/a.out)]
  [Switching to thread 1.1 (Thread 22111.22111)]
  Could not read registers; remote failure reply 'E01'
  (gdb) info threads
    Id   Target Id                   Frame
  * 1.1  Thread 22111.22111 "simple" Could not read registers; remote failure reply 'E01'
  Could not read registers; remote failure reply 'E01'
  (gdb) backtrace
  Python Exception <class 'gdb.error'> Could not read registers; remote failure reply 'E01':
  Could not read registers; remote failure reply 'E01'
  (gdb) thread
  [Current thread is 1.1 (Thread 22111.22111)]
  Could not read registers; remote failure reply 'E01'
  (gdb)

With this patch, it becomes:

  ...
  [Inferior 1 (process 11759) exited normally]
  (gdb) inferior 2
  [Switching to inferior 2 [process 13440] (target:/path/to/a.out)]
  [Switching to thread 2.1 (Thread 13440.13440)]
  #0  <unavailable> in ?? ()
  (gdb) info threads
    Id   Target Id                   Frame
  * 2.1  Thread 13440.13440 "a.out" <unavailable> in ?? ()
  (gdb) backtrace
  #0  <unavailable> in ?? ()
  Backtrace stopped: not enough registers or memory available to unwind further
  (gdb) thread
  [Current thread is 2.1 (Thread 13440.13440)]
  (gdb)

Finally, together with its predecessor, this patch also fixes PR gdb/26877.

Regression-tested on X86_64-Linux.
