[PATCH 1/2] score: Add _CPU_Get_TLS_thread_pointer()
Sebastian Huber
sebastian.huber at embedded-brains.de
Fri Sep 15 07:07:19 UTC 2023
Add _CPU_Get_TLS_thread_pointer() to get the thread pointer which is
used to get the address of thread-local storage objects associated with
a thread.
Update #4920.
