PR42182: Allow thread-local to use __cxa_thread_atexit when -fno-use-cxx-atexit is used

Authored by erichkeane on Jun 13 2019, 10:07 AM.



This matches the GCC behavior, __cxa_thread_atexit should be permissible
even though cxa_atexit is disabled.

It's fine to match the GCC behavior, and it's even somewhat explicable. Could you update the comment to explain, first of all, that this path handles both __cxa_atexit and __cxa_thread_atexit, and secondly that the option is only meant to control the former?

erichkeane marked an inline comment as done.
