If I want to change the signalled state of multiple threads it's a bit cumbersome to do with the "signal" command. What you really want is a way to set the signal state of the desired threads and then just do "continue". This patch adds a new command, queue-signal, to accomplish this. Basically "signal N" == "queue-signal N" + "continue". That's not precisely true in that "signal" can be used to inject any signal, including signals set to "nopass"; whereas "queue-signal" just queues the signal as if the thread stopped because of it. "nopass" handling is done when the thread is resumed which "queue-signal" doesn't do. One could add extra complexity to allow queue-signal to be used to deliver "nopass" signals like the "signal" command. I have no current need for it so in the interests of incremental complexity, I have left such support out and just have the code flag an error if one tries to queue a nopass signal. gdb/ChangeLog: * NEWS: Mention new "queue-signal" command. * infcmd.c (queue_signal_command): New function. (_initialize_infcmd): Add new queue-signal command. gdb/doc/ChangeLog: * gdb.texinfo (Signaling): Document new queue-signal command. gdb/testsuite/ChangeLog: * gdb.threads/queue-signal.c: New file. * gdb.threads/queue-signal.exp: New file.
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.
