Since silent handling of eof is usually the wrong thing to do, this
patch makes gdb_test_multiple handle it for all $any_spawn_id.
Currently, against gdbserver, interrupt.exp occasionaly fails like
this:
FAIL: gdb.base/interrupt.exp: send end of file
gdb.log with expect debug output enabled shows:
expect: does "\r\n\r\nChild exited with status 0\r\nGDBserver exiting\r\n" (spawn_id exp8) match regular expression "end of file"? Gate "end of file"? gate=no
expect: read eof
expect: set expect_out(spawn_id) "exp8"
expect: set expect_out(buffer) "\r\n\r\nChild exited with status 0\r\nGDBserver exiting\r\n"
FAIL: gdb.base/interrupt.exp: send end of file
Note "expect: read eof" for spawn_id=exp8. exp8 is
inferior_spawn_id/gdbserver_spawn_id. That means
expect/gdb_test_multiple saw gdbserver exit before we got the expected
gdb output. Since there's no explicit pattern for "eof", expect (and
thus gdb_test_multiple) just returns.
After this commit, we get instead:
ERROR: Process no longer exists
UNRESOLVED: gdb.base/interrupt.exp: send end of file
Note that before we still got an FAIL because $saw_inferior_exit is 0
when we get to:
gdb_assert { $saw_eof && $saw_inferior_exit } $msg
Fixing the fail (now unresolved) will be the subject of a separate
patch.

* lib/gdb.exp (gdb_test_multiple): Match eof/full_buffer/timeout
on $any_spawn_id instead of only on $gdb_spawn_id.
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.
