From: Ilia Mirkin Date: Fri, 1 Jul 2016 23:10:36 +0000 (-0400) Subject: glsl: don't try to lower non-gl builtins as if they were gl_FragData X-Git-Tag: upstream/17.1.0~8276 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a37e46323c7e18bec4160f2f66847c10b7041dc1;p=platform%2Fupstream%2Fmesa.git glsl: don't try to lower non-gl builtins as if they were gl_FragData If a shader has an output array, it will get treated as though it were gl_FragData and rewritten into gl_out_FragData instances. We only want this to happen on the actual gl_FragData and not everything else. This is a small part of the problem pointed out by the below bug.
