From a4078b819f648fb8e2b6dde8f6017f46a38c54f2 Mon Sep 17 00:00:00 2001 From: Timothy Arceri Date: Tue, 24 Jan 2017 08:35:51 +1100 Subject: [PATCH] i965: add support for cached shaders with xfb qualifiers For now this disables the shader cache when transform feedback is enabled via the GL API as we don't currently allow for it when generating the sha for the shader.
