From 6a2baf3a06125405aa648e208af782e53f1312c0 Mon Sep 17 00:00:00 2001 From: Paul Berry Date: Mon, 10 Jun 2013 14:01:45 -0700 Subject: [PATCH] glsl/linker: Make update_array_sizes apply to just uniforms. Commit 586b4b5 (glsl: Also update implicit sizes of varyings at link time) extended update_array_sizes() to apply to both uniforms and shader ins/outs. However, doing creates problems for geometry shaders, because update_array_sizes() assumes that variables with matching names in different parts of the pipeline should have the same sizes. With the addition of geometry shaders, this is no longer true (e.g. both vertex and geometry shaders have a gl_ClipDistance output variable, but there's no reason these variables should have the same sizes). The original reason for commit 586b4b5 (avoid problems with gl_TexCoord being 0 length) has since been addressed by commit 6f53921 (linker: Ensure that unsized arrays have a size after linking). So go ahead and switch update_array_sizes() back to only acting on uniforms.
