This commit extends the CLI a bit for multi-target, in three ways. #1 - New "info connections" command. This is a new command that lists the open connections (process_stratum targets). For example, if you're debugging two remote connections, a couple local/native processes, and a core dump, all at the same time, you might see something like this: (gdb) info connections Num What Description 1 remote 192.168.0.1:9999 Remote serial target in gdb-specific protocol 2 remote 192.168.0.2:9998 Remote serial target in gdb-specific protocol * 3 native Native process 4 core Local core dump file #2 - New "info inferiors" "Connection" column You'll also see a new matching "Connection" column in "info inferiors", showing you which connection an inferior is bound to: (gdb) info inferiors Num Description Connection Executable 1 process 18526 1 (remote 192.168.0.1:9999) target:/tmp/a.out 2 process 18531 2 (remote 192.168.0.2:9998) target:/tmp/a.out 3 process 19115 3 (native) /tmp/prog1 4 process 6286 4 (core) myprogram * 5 process 19122 3 (native) /bin/hello #3 - Makes "add-inferior" show the inferior's target connection "add-inferior" now shows you the connection you've just bound the inferior to, which is the current process_stratum target: (gdb) add-inferior [New inferior 2] Added inferior 2 on connection 1 (extended-remote localhost:2346) gdb/ChangeLog: 2020-01-10 Pedro Alves <palves@redhat.com> * Makefile.in (COMMON_SFILES): Add target-connection.c. * inferior.c (uiout_field_connection): New function. (print_inferior): Add new "connection-id" column. (add_inferior_command): Show connection number/string of added inferior. * process-stratum-target.h (process_stratum_target::connection_string): New virtual method. (process_stratum_target::connection_number): New field. * remote.c (remote_target::connection_string): New override. * target-connection.c: New file. * target-connection.h: New file. * target.c (decref_target): Remove process_stratum targets from the connection list. (target_stack::push): Add process_stratum targets to the connection list. gdb/testsuite/ChangeLog: 2020-01-10 Pedro Alves <palves@redhat.com> * gdb.base/kill-detach-inferiors-cmd.exp: Adjust expected output of "add-inferior". * gdb.base/quit-live.exp: Likewise. * gdb.base/remote-exec-file.exp: Likewise. * gdb.guile/scm-progspace.exp: Likewise. * gdb.linespec/linespec.exp: Likewise. * gdb.mi/new-ui-mi-sync.exp: Likewise. * gdb.mi/user-selected-context-sync.exp: Likewise. * gdb.multi/multi-target.exp (setup): Add "info connection" and "info inferiors" tests. * gdb.multi/remove-inferiors.exp: Adjust expected output of "add-inferior". * gdb.multi/watchpoint-multi.exp: Likewise. * gdb.python/py-inferior.exp: Likewise. * gdb.server/extended-remote-restart.exp: Likewise. * gdb.threads/fork-plus-threads.exp: Adjust expected output of "info inferiors". * gdb.threads/forking-threads-plus-breakpoint.exp: Likewise. * gdb.trace/report.exp: Likewise.

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.
