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

# Short description: A fragment shader that covers specific SPIR-V reader code paths

# 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 320 es
#
# #define _int_0 _GLF_uniform_int_values[0]
# #define _int_1 _GLF_uniform_int_values[1]
# #define _float_1_0 _GLF_uniform_float_values[0]
#
# precision highp int;
# precision highp float;
#
# // Contents of _GLF_uniform_int_values: [0, 1]
# layout(set = 0, binding = 0) uniform buf0
# {
#     int _GLF_uniform_int_values[2];
# };
# // Contents of _GLF_uniform_float_values: 1.0
# layout(set = 0, binding = 1) uniform buf1
# {
#     float _GLF_uniform_float_values[1];
# };
# layout(location = 0) out vec4 _GLF_color;
#
# // Contents of m: [1.0, 5.0, 3.0, 7.0, 9.0, 6.0, 7.0, 8.0, 1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0]
