(linux_nat_async_events_state): Delete. (struct waitpid_result): Delete. (waitpid_queue): Delete. (queued_waitpid_1): Delete. (async_file_flush): New. (queued_waitpid, push_waitpid): Delete. (async_file_mark): New. (drain_queued_events): Delete. (my_waitpid): Remove locally queued events handling. (linux_test_for_tracefork): Upjust. (linux_child_follow_fork): Ditto. (sync_sigchld_action): Delete. (blocked_mask): Reinstate. (async_sigchld_action): Rename to... (sigchld_action): ... this. (block_child_signals): New. (restore_child_signals_mask): New. (lin_lwp_attach_lwp): Adjust. (linux_nat_create_inferior): Ditto. (linux_nat_attach): Also use lp->status in async mode. (get_pending_status): Don't use queued_waitpid. (linux_nat_detach): Don't drain locally queued events. (linux_nat_resume): Allow pending wait statuses stored lp->status in async mode. If returning early due to a pending event, re-register the event source. (stop_wait_callback): Allow pending wait statuses stored lp->status in async mode. (pipe_to_local_event_queue, local_event_queue_to_pipe): Delete. (linux_nat_wait): Rename to ... (linux_nat_wait_1): ... this. Allow pending wait statuses stored lp->status in async mode. Always add WNOHANG to the waitpid options in async mode. (linux_nat_wait): New. (kill_callback): Don't drain locally queued events. (sigchld_handler): Rewrite. (linux_nat_is_async_p, linux_nat_can_async_p): Fix comments to refer to "set target-async". (linux_nat_async_mask): If in non-stop, and re-enabling async mode, re-register the target event source in the event loop. (linux_nat_event_pipe_pop, linux_nat_event_pipe_push) (get_pending_events, async_sigchld_handler) (linux_nat_async_events): Delete. (handle_target_event): New. (linux_nat_async_file_handler): Delete. (linux_async_pipe): New. (linux_nat_async): Only re-register in the event loop if not registered yet. Always notify the event-loop once if enabling the event source. (linux_nat_stop_lwp): Rewrite to handle pending events stored in lp->status, not in the locally queued event list. (linux_nat_stop): Don't mask out async event handling. (linux_nat_setup_async): Delete. (_initialize_linux_nat): Adjust. (lin_thread_get_thread_signals): blocked_mask is global again. Adjust.
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.
