From 6395a0ecf2224f7647262aa82d3ebba69cba891b Mon Sep 17 00:00:00 2001 From: =?utf8?q?Mathias=20Fr=C3=B6hlich?= Date: Sat, 27 Jan 2018 12:09:00 -0700 Subject: [PATCH] mesa: Reduce ffvertex_prog state_key to 36 bytes. MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Using lower alignment restrictions for the state key fields finally yields to a smaller hashing state key.
