With the multi-target work, each inferior will have its own target stack, so to call a target method, we'll need to make sure that the inferior in question is the current one, otherwise target->beneath() calls will find the target beneath in the wrong inferior. In some places, it's much more convenient to be able to check whether an inferior has execution without having to switch to it in order to call target_has_execution on the right inferior/target stack, to avoid side effects with switching inferior/thread/program space. The current target_ops::has_execution method takes a ptid_t as parameter, which, in a multi-target world, isn't sufficient to identify the target. This patch prepares to address that, by changing the parameter to an inferior pointer instead. From the inferior, we'll be able to query its target stack to tell which target is beneath. Also adds a new inferior::has_execution() method to make callers a bit more natural to read. gdb/ChangeLog: 2020-01-10 Pedro Alves <palves@redhat.com> * corelow.c (core_target::has_execution): Change parameter type to inferior pointer. * inferior.c (number_of_live_inferiors): Use inferior::has_execution instead of target_has_execution_1. * inferior.h (inferior::has_execution): New. * linux-thread-db.c (thread_db_target::update_thread_list): Use inferior::has_execution instead of target_has_execution_1. * process-stratum-target.c (process_stratum_target::has_execution): Change parameter type to inferior pointer. Check the inferior's PID instead of inferior_ptid. * process-stratum-target.h (process_stratum_target::has_execution): Change parameter type to inferior pointer. * record-full.c (record_full_core_target::has_execution): Change parameter type to inferior pointer. * target.c (target_has_execution_1): Change parameter type to inferior pointer. (target_has_execution_current): Adjust. * target.h (target_ops::has_execution): Change parameter type to inferior pointer. (target_has_execution_1): Change parameter type to inferior pointer. Change return type to bool. * tracefile.h (tracefile_target::has_execution): Change parameter type to inferior pointer. |

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.
