I thought that the GLSL compiler itself eliminated unused uniforms at link
time...at least, if I try and run the following shader_runner test on either
i965 or swrast:
[require]
GLSL >= 1.10
[vertex shader]
void main() { gl_Position = gl_Vertex; }
[fragment shader]
uniform float foo;
void main() { gl_FragColor = vec4(1.0); }
[test]
uniform float foo 1.0
draw rect -1 -1 2 2
...it tells me:
cannot get location of uniform "foo"
