From: Emil Velikov Date: Tue, 24 Jan 2017 21:21:09 +0000 (+0000) Subject: util/sha1: rework _mesa_sha1_{init,final} X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=a9a4028fd7136ee2ee7bf0efa8179e7a6312f008;p=mesa.git util/sha1: rework _mesa_sha1_{init,final} Rather than having an extra memory allocation [that we currently do not and act accordingly] just make the API take an pointer to a stack allocated instance. This and follow-up steps will effectively make the _mesa_sha1_foo simple define/inlines around their SHA1 counterparts.
