openbsd/src/lib/libc/stdlib/atexit.h, branch OPENBSD_7_9

Move __cxa_thread_atexit* to its own .c file to avoid pulling the code

2017-12-16T20:06:56+00:00

(w/ _dlctl reference) into static executables. It's all Mark's code so put his preferred copyright on it. ok kettenis@

Implement __cxa_thread_atexit to support C++11 thread_local scope. The

2017-12-05T13:45:31+00:00

interface is also made available as __cxa_thread_atexit_impl to satisfy the needs of GNU libstdc++. ok guenther@, millert@

Hide atexit and atexit_register_cleanup()

2015-10-25T18:01:24+00:00

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@

Always call atexit handlers as if they were registered with __cxa_atexit.

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 and Elliott Hughes . ok matthew@

Two small cleanups to atexit: remove unneeded __atexit_invalid, and

2013-06-02T21:08:36+00:00

move the call_depth decrement so it happens unconditionally and can still return to 0 when called with dso!=NULL. ok millert

Add __cxa_atexit() support for gcc3. This provides support for shared object destructors called at dlclose() time. Inspired by similar changes in FreeBSD and NetBSD.

re-enable function pointer table protection, this time make sure that

malloc.c gets the first mmap() call (since it depends on that, for its sbrk(0) use). ok deraadt@

Replace atexit handler. mprotect() the pages so an attempt to modify the
