# 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:
# #version 310 es
# #define _int_0 _GLF_uniform_int_values[0]
# #define _int_1 _GLF_uniform_int_values[1]
#
# precision highp float;
#
# precision highp int;
#
# // Contents of _GLF_uniform_int_values: [0, 1]
# layout(set = 0, binding = 0) uniform buf0
# {
# int _GLF_uniform_int_values[2];
# };
#
# layout(location = 0) out vec4 _GLF_color;
#
# void main()
# {
# int a = 1 >> (_int_0 << 5) >> _int_0;
# if (a == 1)
# {
# _GLF_color = vec4(_int_1, _int_0, _int_0, _int_1);
# }
# else
# {
# _GLF_color = vec4(a);
# }
# }
