From 8ae4317c3643f1728f99172812df6df2d30456bb Mon Sep 17 00:00:00 2001 From: =?utf8?q?Tapani=20P=C3=A4lli?= Date: Mon, 26 Oct 2015 11:13:14 +0200 Subject: [PATCH] mesa: add additional checks for uniform location query MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Patch adds additional check to make sure we don't return locations for structures or arrays of structures. From page 79 of the OpenGL 4.2 spec: "A valid name cannot be a structure, an array of structures, or any portion of a single vector or a matrix." v2: use without-array() to simplify code (Timothy) No Piglit or CTS regressions observed.
