* acconfig.h: Add HAVE_TKILL_SYSCALL definition check. * config.in: Regenerated. * configure.in: Add test for syscall function and check for __NR_tkill macro in <syscall.h> to set HAVE_TKILL_SYSCALL. * configure: Regenerated. * lin-lwp.c [HAVE_TKILL_SYSCALL]: Include <unistd.h> and <sys/syscall.h>. (kill_lwp): New function that uses tkill syscall or uses kill, depending on whether threading model is nptl or not. All callers of kill() changed to use kill_lwp(). (lin_lwp_wait): Make special check when WIFEXITED occurs to see if all threads have already exited in the nptl model. (stop_and_resume_callback): New callback function used by the lin_lwp_wait thread exit handling code. (stop_wait_callback): Check for threads already having exited and delete such threads fromt the lwp list when discovered. (stop_callback): Don't assert retcode of kill call. Roland McGrath <roland@redhat.com> * i386-linux-nat.c (ps_get_thread_area): New function needed by nptl libthread_db.
