Then in _csu_finish(), invoke the dl_clean_boot() callback to free ld.so's startup bits before main() gets control. Other cleanups this permits: - move various startup structures into .data.rel.ro - the dl* stubs in libc can be strong and call the callbacks provided via _dl_cb - no longer need to conditionalize dlctl() calls on presence of _DYNAMIC original concept and full diff ok kettenis@ ok deraadt@ Move __cxa_thread_atexit* to its own .c file to avoid pulling the code 2017-12-16T20:06:56+00:00 guenther 2017-12-16T20:06:56+00:00 urn:sha1:09687c04dc436ea29235c588185e43443b906e9f (w/ _dlctl reference) into static executables.
