2008-06-28 Pedro Alves <pedro@codesourcery.com> * linux-nat.c (enum sigchld_state): New. (linux_nat_async_events_state): Renamed from linux_nat_async_events_enabled. (linux_nat_event_pipe_push, my_waitpid): Adjust. (sigchld_default_action): New. (lin_lwp_attach_lwp): Adjust. Call linux_nat_async_events unconditionally. (linux_nat_create_inferior): Set events state to sigchld_default state. (linux_nat_resume): Adjust. (linux_nat_wait): Call linux_nat_async_events unconditionally. (sigchld_handler): Adjust. (linux_nat_async_mask): Don't set SIGCHLD actions here. (get_pending_events): Adjust. (linux_nat_async_events): Rewrite to handle enum sigchld_state instead of a boolean. (linux_nat_async): Adjust. (_initialize_linux_nat): Capture default SIGCHLD action into sigchld_default_action. gdb/testsuite/ 2008-06-28 Pedro Alves <pedro@codesourcery.com> * gdb.base/sigchld.c, gdb.base/sigchld.exp: New test.
