Pedro Alves 4ea7412e53 gdb.threads/step-over-thread-exit.exp improvements
This commit makes the following improvements to
gdb.threads/step-over-thread-exit.exp:

- Add a third axis to stepping over the breakpoint with displaced vs
  inline stepping -- also test with no breakpoint at all.

- Check that when GDB reports "Command aborted, thread exited.", the
  selected thread is the thread that exited.  This is always true
  currently on GNU/Linux by coincidence, but a similar testcase on AMD
  GPU exposed a problem here.  Better make the testcase catch any
  potential regression.

- Fixes a race that Simon ran into with GDBserver testing.

    [New Thread 2143071.2143438]

    Thread 3 "step-over-threa" hit Breakpoint 2, 0x000055555555524e in my_exit_syscall () at .../testsuite/lib/my-syscalls.S:74
    74      SYSCALL (my_exit, __NR_exit)
    (gdb) FAIL: gdb.threads/step-over-thread-exit.exp: displaced-stepping=auto: non-stop=on: target-non-stop=on: schedlock=off: cmd=next: ns_stop_all=0: command aborts when thread exits

  I was not able to reproduce it, but I believe that what happens is
  the following:

  Once we continue, the thread 2 exits, and the main thread thus
  unblocks from its pthread_join, and spawns a new thread.  That new
  thread may hit the breakpoint at my_exit_syscall very quickly.  GDB
  could then see/process that breakpoint event before the thread exit
  event for the thread we care about, which would result in the
  failure seen above.

  The fix here is to not loop and start a new thread at all in the
  scenario where the race can happen.  We only need to loop and spawn
  new threads when testing with "cmd=continue" and schedlock off, in
  which case GDB doesn't abort the command when the thread exits.

		   README for GNU development tools

This directory contains various GNU compilers, assemblers, linkers, 
debuggers, etc., plus their support routines, definitions, and documentation.

If you are receiving this as part of a GDB release, see the file gdb/README.
If with a binutils release, see binutils/README;  if with a libg++ release,
see libg++/README, etc.  That'll give you info about this
package -- supported targets, how to use it, how to report bugs, etc.

It is now possible to automatically configure and build a variety of
tools with one command.  To build all of the tools contained herein,
run the ``configure'' script here, e.g.:

	./configure 
	make

To install them (by default in /usr/local/bin, /usr/local/lib, etc),
then do:
	make install

(If the configure script can't determine your type of computer, give it
the name as an argument, for instance ``./configure sun4''.  You can
use the script ``config.sub'' to test whether a name is recognized; if
it is, config.sub translates it to a triplet specifying CPU, vendor,
and OS.)

If you have more than one compiler on your system, it is often best to
explicitly set CC in the environment before running configure, and to
also set CC when running make.  For example (assuming sh/bash/ksh):

	CC=gcc ./configure
	make

A similar example using csh:

	setenv CC gcc
	./configure
	make

Much of the code and documentation enclosed is copyright by
the Free Software Foundation, Inc.  See the file COPYING or
COPYING.LIB in the various directories, for a description of the
GNU General Public License terms under which you can copy the files.

REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info
on where and how to report problems.
