If you want to use catch_errors with a function with parameters, then currently you have to manually write a "capture" struct wrapping the arguments and marshall/unmarshall that. https://sourceware.org/ml/gdb-patches/2017-09/msg00834.html proposed adjusting catch_errors to use gdb::function_view, which would allow passing lambdas with automatic captures. However, it seems like using TRY/CATCH directly instead ends up producing clearer and easier to debug code. This is what this commit does. Note that removing catch_errors exposes further cleanup opportunities around no longer having to follow catch_errors callback type, and also removes a few cleanups. I didn't do anything to save/restore current_uiout because I think that should be the responsibility of the code that changes current_uiout in the first place. (Another approach could be to make catch_errors a variadic template like: template<typename Function, typename... Args> int catch_errors (const char *errstring, return_mask mask, Function &&func, Args... args); and then with: extern void function_with_args (int, int); extern void function_with_no_args (); calls to the above functions would be wrapped like this: catch_errors ("some error happened", RETURN_MASK_ERROR, function_with_args, arg1, arg2); catch_errors ("some error happened", RETURN_MASK_ERROR, function_with_no_args); but I'm thinking that that doesn't improve much if at all either.) gdb/ChangeLog 2017-10-10 Pedro Alves <palves@redhat.com> Tom Tromey <tom@tromey.com> * breakpoint.c (breakpoint_cond_eval): Change return type to bool and reverse logic.

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.
