From 68fc4b415e322f6744299e39864fbc377c6eff74 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Fri, 21 May 2010 09:32:38 -0700 Subject: Remove demos that have moved to git+ssh://git.freedesktop.org/git/mesa/demos. The remaining programs are ones I've had difficulty finding a build environment for to make the build system or are unit tests that should probably live next to their code instead. Hopefully people can bring over the build for remaining pieces they care about. --- progs/glsl/linktest.c | 255 -------------------------------------------------- 1 file changed, 255 deletions(-) delete mode 100644 progs/glsl/linktest.c (limited to 'progs/glsl/linktest.c') diff --git a/progs/glsl/linktest.c b/progs/glsl/linktest.c deleted file mode 100644 index ec3fffbf9c..0000000000 --- a/progs/glsl/linktest.c +++ /dev/null @@ -1,255 +0,0 @@ -/** - * Test linking of multiple compilation units. - * Brian Paul - * 28 March 2009 - */ - -#include -#include -#include -#include -#include -#include -#include -#include "shaderutil.h" - - -static GLfloat diffuse[4] = { 0.5f, 1.0f, 0.5f, 1.0f };
