* Move __cxa_thread_atexit* to its own .c file to avoid pulling the codeguenther2017-12-161-36/+3

| | | | | _libc___cxa_thread_atexit_impl reference on gcc architectures that breaks the build.
* Implement __cxa_thread_atexit to support C++11 thread_local scope. Thekettenis2017-12-051-1/+53
| | | | | | | interface is also made available as __cxa_thread_atexit_impl to satisfy the needs of GNU libstdc++. ok guenther@, millert@
* libc.so can't be unloaded, so move the hidden atexit() and pthread_atfork()guenther2015-11-101-1/+13
| | | | | | | | | | | stubs for the executable from crtbegin.o into libc, which lets them be excluded from static links that don't use them. For this, drop the normal crt{begin,end}S.o from libc.so: the .init and .fini sections for libc aren't called at the right times anyway, so it's good that they're unused. libc.so just needs __guard_local and the .note.openbsd.ident section, so add them to stack_protector.c for now (this will be improved) "good time" deraadt@
* Move the _atfork_list definition to atexit.c so that the fork syscall stubguenther2015-10-251-1/+5

* Hide __atexit and __atexit_register_cleanup()guenther2015-10-251-1/+3
| | | | | | | | Wrap __cxa_{atexit,finalize}() so the call from exit() goes direct Switch regress/lib/libc/atexit/ to be built with -static so that it can still access __atexit* ok millert@ jca@
* Make pthread_atfork() track the DSO that called it like atexit() does,guenther2015-04-071-1/+19
| | | | | | | | | | unregistering callbacks if the DSO is unloaded. Move the callback handling from libpthread to libc, though libpthread still overrides the inner call to handle locking and thread-library reinitialization. Major version bump for both libc and libpthread. verification that this fixes various ports ajacoutot@ asm assistance miod@; ok millert@ deraadt@

* Always call atexit handlers as if they were registered with __cxa_atexit.kettenis2014-06-181-9/+6
| | | | | | | | | | | The extra argument doesn't hurt genuine atexit handlers and this fixes a bug where we didn't provide the argument (effectively passing garbage) for functions registered with __cxa_atexit in the main executable. Pointed out by Dmitriy Ivanov <dimitry@google.com> and Elliott Hughes <enh@google.com>. ok matthew@

| | | | | | | | | | right __dso_handle and have dlopen'ed shared objects run their atexit handlers when they get unloaded. This is what Linux does, and several ports depend on this behaviour (and will crash upon exit without this chang). Based on an earlier diff from matthew@ Tested by ajacoutot@ ok deraadt@
