2015-12-17	Remove support for LinuxThreads and vendor 2.4 kernels w/ backported NPTL	Pedro Alves	1	-58/+5
	Since we now rely on PTRACE_EVENT_CLONE being available (added in Linux 2.5.46), we're relying on NPTL. This commit removes the support for older LinuxThreads, as well as the workarounds for vendor 2.4 kernels with NPTL backported. - Rely on tkill being available. - Assume gdb doesn't get cancel signals. - Remove code that checks the LinuxThreads restart and cancel signals in the inferior. - Assume that __WALL is available. - Assume that non-leader threads report WIFEXITED. - Thus, no longer need to send signal 0 to check whether threads are still alive. - Update comments throughout. Tested on x86_64 Fedora 20, native and gdbserver. gdb/ChangeLog: * configure.ac: Remove tkill checks. * configure, config.in: Regenerate. * linux-nat.c: Remove HAVE_TKILL_SYSCALL check. Update top level comments. (linux_nat_post_attach_wait): Remove 'cloned' parameter. Use __WALL. (attach_proc_task_lwp_callback): Don't set the cloned flag. (linux_nat_attach): Adjust. (kill_lwp): Remove HAVE_TKILL_SYSCALL check. No longer fall back to 'kill'. (linux_handle_extended_wait): Use __WALL. Don't set the cloned flag. (wait_lwp): Use __WALL. Update comments. (running_callback, stop_and_resume_callback): Delete. (linux_nat_filter_event): Don't stop and resume all lwps. Don't check if the event LWP has previously exited. (check_zombie_leaders): Update comments. (linux_nat_wait_1): Use __WALL. (kill_wait_callback): Don't handle clone processes separately. Use __WALL instead. (linux_thread_alive): Delete. (linux_nat_thread_alive): Return true as long as the LWP is in the LWP list. (linux_nat_update_thread_list): Assume the kernel supports PTRACE_EVENT_CLONE. (get_signo): Delete. (lin_thread_get_thread_signals): Remove LinuxThreads references. No longer check __pthread_sig_restart / __pthread_sig_cancel in the inferior. * linux-nat.h (struct lwp_info) <cloned>: Delete field. * linux-thread-db.c: Update comments. (_initialize_thread_db): Remove LinuxThreads references. * nat/linux-waitpid.c (my_waitpid): No longer emulate __WALL. Pass down flags unmodified. * linux-waitpid.h (my_waitpid): Update documentation. gdb/gdbserver/ChangeLog: * linux-low.c (linux_kill_one_lwp): Remove references to LinuxThreads. (kill_lwp): Remove HAVE_TKILL_SYSCALL check. No longer fall back to 'kill'. (linux_init_signals): Delete. (initialize_low): Adjust. * thread-db.c (thread_db_init): Remove LinuxThreads reference.

2014-09-12	Clarify GDBSERVER use in linux-waitpid.c	Gary Benson	1	-5/+6
	This commit makes linux-waitpid.c include common-defs.h. GDB's inclusion of defs.h is removed, but gdbserver's inclusion of server.h remains to support some gdbserver-specific debug code that cannot presently be merged. A new FIXME documents this. gdb/ChangeLog: * nat/linux-waitpid.c: Include common-defs.h. [GDBSERVER]: Add FIXME comment. [!GDBSERVER]: Don't include defs.h or signal.h. (linux_debug) [!GDBSERVER]: Remove empty block.
