| # A test for a bug found by GraphicsFuzz. |
| |
| # A fragment shader that uses pow. |
| # Derived from the following GLSL fragment shader. |
| # We check that all pixels are red. The test passes because main does |
| # some computation and then writes red to _GLF_color. |

| # vec2 a = vec2(1.0); |
| # vec4 b = vec4(1.0); |
| # pow(vec4(a, vec2(1.0)), b); |
