Subject: [PATCH 7/20] inflate: eliminate memzero usage
Date: Thu, 22 Dec 2005 12:26:36 -0600 [thread overview]
Message-ID: <8.150843412@selenic.com> (raw)
In-Reply-To: <7.150843412@selenic.com>
inflate: replace call to memzero with simple loop
This is the only user of memzero in the inflate code and it's only for
16 bytes. Removing this lets us drop a copy of memzero from most
lib/inflate users.
