After this mailing list posting: https://sourceware.org/pipermail/gdb-patches/2023-February/196607.html it seems to me that in practice an Ada task maps 1:1 with a GDB thread, and so it doesn't really make sense to allow uses to give both a thread and a task within a single breakpoint or watchpoint condition. This commit updates GDB so that the user will get an error if both are specified. I've added new tests to cover the CLI as well as the Python and Guile APIs. For the Python and Guile testing, as far as I can tell, this was the first testing for this corner of the APIs, so I ended up adding more than just a single test. For documentation I've added a NEWS entry, but I've not added anything to the docs themselves. Currently we document the commands with a thread-id or task-id as distinct command, e.g.: 'break LOCSPEC task TASKNO' 'break LOCSPEC task TASKNO if ...' 'break LOCSPEC thread THREAD-ID' 'break LOCSPEC thread THREAD-ID if ...' As such, I don't believe there is any indication that combining 'task' and 'thread' would be expected to work; it seems clear to me in the above that those four options are all distinct commands. I think the NEWS entry is enough that if someone is combining these keywords (it's not clear what the expected behaviour would be in this case) then they can figure out that this was a deliberate change in GDB, but for a new user, the manual doesn't suggest combining them is OK, and any future attempt to combine them will give an error.

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.
