This fixes PR gdb/17130.
The bug is that some code in utils.c was not updated during the target
delegation change:
if (job_control
/* If there is no terminal switching for this target, then we can't
possibly get screwed by the lack of job control. */
|| current_target.to_terminal_ours == NULL)
fatal ("Quit");
else
fatal ("Quit (expect signal SIGINT when the program is resumed)");
After the delegation change, to_terminal_ours will never be NULL.
I think this bug can be seen before the target delegation change by
enabling target debugging -- this would also cause to_terminal_ours to
be non-NULL.
The fix is to introduce a new target_supports_terminal_ours function,
that properly checks the target stack. This is not perhaps ideal, but
I think is a reasonable-enough approach, and in keeping with some
other existing code of the same form.
This patch also fixes a similar bug in target_supports_delete_record.

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.
