From: Paul Berry Date: Sat, 28 Sep 2013 00:35:27 +0000 (-0700) Subject: glsl: Don't allow invalid identifiers as interface block names. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=f2dd3a04ce3bef550eca7893a1e6907cf8e43bc2;p=mesa.git glsl: Don't allow invalid identifiers as interface block names. Note: we need to make an exception for the gl_PerVertex interface block, since this is allowed to be redeclared. Future patches will make redeclaration of gl_PerVertex work properly. Fixes piglit test spec/glsl-1.50/compiler/interface-block-name-uses-gl-prefix.vert.
