| # A test for a bug found by GraphicsFuzz. |
| |
| # Short description: A fragment shader that calls modf twice, once with color |
| |
| # The test passes because the shader always writes the color red using modf. |
| |
| SHADER vertex variant_vertex_shader PASSTHROUGH |
| |
| # variant_fragment_shader is derived from the following GLSL: |
| # #version 310 es |
| # precision highp float; |
| # |
| # layout(location = 0) out vec4 _GLF_color; |
| # |
| # void main() |
| # { |
| # vec4 temp; |
| # modf(vec4(1.0), temp); |
| # modf(vec4(1.0, 0.0, 0.0, 1.0), _GLF_color); |
| # } |
