Bug 74887 – [CSS Shaders] Should get link error for varying value that doesn't exist

• Status: RESOLVED
• Resolution: INVALID
• Component: CSS

[Alan Stearns]

If you refer to a varying value that is not written by the fragment shader, you should get a link error.

Example:

precision highp float;

varying vec4 bogus_value;

void main() {
  gl_FragColor = bogus_value;
}
