| # A test for a coverage-gap found by the GraphicsFuzz project. |

| # Short description: A fragment shader that covers specific NIR code paths |
| |
| # The test passes because the shader always writes red. |

| # variant_fragment_shader is derived from the following GLSL: |

| # #define _float_1_0 _GLF_uniform_float_values[0] |

| # // Contents of _GLF_uniform_float_values: 1.0 |
| # layout(set = 0, binding = 0) uniform buf0 |
| # { |
| # float _GLF_uniform_float_values[1]; |
| # }; |
| # // Contents of _GLF_uniform_int_values: 0 |
| # layout(set = 0, binding = 1) uniform buf1 |
