From cad0cf4ceeaac708591d064642e12d3b8daa4e05 Mon Sep 17 00:00:00 2001 From: Francisco Jerez Date: Tue, 20 Jan 2015 16:12:18 +0200 Subject: mesa: Validate original image internal format rather than derived mesa format. This matches what _mesa_BindImageTextures() does. The derived image format (gl_texture_image::TexFormat) isn't necessarily equivalent to the internal format of the texture image. If a forbidden internal format has been specified we need to mark the image unit as invalid as required by the spec, regardless of the derived format. Fixes the "invalid" ARB_shader_image_load_store piglit test.
