Subject: [PATCH] Use weak reference for _REENT_SMALL
Date: Wed, 18 May 2022 19:13:07 +0200 [thread overview]
Message-ID: <20220518171307.53663-3-sebastian.huber@embedded-brains.de> (raw)
In-Reply-To: <20220518171307.53663-1-sebastian.huber@embedded-brains.de>
Avoid a strong reference to __sfp[] for _impure_data. The __sfp[] is linked in
if __sinit() is used for example.
