# A test for a coverage-gap found by the GraphicsFuzz project.
# Short description: A fragment shader that covers a specific instruction simplification path
# The test passes because the shader always writes red.
SHADER vertex variant_vertex_shader PASSTHROUGH
# variant_fragment_shader is derived from the following GLSL:

# #define _float_0_0 _GLF_uniform_float_values[0]

# precision highp float;

# // Contents of _GLF_uniform_int_values: [1, 0]
# layout(set = 0, binding = 0) uniform buf0
# {
# int _GLF_uniform_int_values[2];
# };
#
# // Contents of _GLF_uniform_float_values: [0.0, 1.0]
# layout(set = 0, binding = 1) uniform buf1
# {
# float _GLF_uniform_float_values[2];

# void main()
