2012-06-28 Jan Kratochvil <jan.kratochvil@redhat.com> Pedro Alves <palves@redhat.com> * gdbthread.h (ALL_THREADS): New macro. (thread_list): Declare. * infrun.c (handle_inferior_event) <spurious signal>: Don't keep going, but instead fall through to the stepping handling. * linux-nat.c (resume_lwp): New parameter 'signo'. Resume with the passed in signal. Adjust debug output. (resume_callback): Rename to ... (linux_nat_resume_callback): ... this. Pass the thread's last stop signal, if in "pass" state. (linux_nat_resume): Adjust to rename. (stop_wait_callback): New assertion. Don't respawn signals; instead let the LWP remain with SIGNALLED set. (linux_nat_wait_1): Remove flushing of pending SIGSTOPs. * remote.c (append_pending_thread_resumptions): New. (remote_vcont_resume): Call it. * target.h (target_resume): Extend comment. gdb/testsuite/ 2012-06-28 Jan Kratochvil <jan.kratochvil@redhat.com> Pedro Alves <palves@redhat.com> * gdb.threads/siginfo-threads.exp: New file. * gdb.threads/siginfo-threads.c: New file. * gdb.threads/sigstep-threads.exp: New file. * gdb.threads/sigstep-threads.c: New file.
