[PATCH nolibc 08/19] tools/nolibc: string: Remove the `_nolibc_memcpy_down()` function

From: Paul E. McKenney
Date: Thu Oct 12 2023 - 15:32:54 EST


From: Ammar Faizi <ammarfaizi2@xxxxxxxxxxx>

This nolibc internal function is not used. Delete it. It was probably
supposed to handle memmove(), but today the memmove() has its own
implementation.
