From c1f1d8522c4650f55fac3a57466c9788f80f82f6 Mon Sep 17 00:00:00 2001 From: Paul Berry Date: Mon, 22 Jul 2013 11:44:24 -0700 Subject: [PATCH] glsl: Permit non-ubo input interface arrays to use non-const indexing. From the GLSL ES 3.00 spec: "All indexes used to index a uniform block array must be constant integral expressions." Similar text exists in GLSL specs since 1.50. When we implemented this, the only type of interface block supported by Mesa was uniform blocks, so we required all indexes used to index any interface block to be constant integral expressions. Now that we are adding interface block support for GLSL 1.50, we need a more specific check.
