# A test for a bug found by GraphicsFuzz.

# Short description: A fragment shader with two loops with breaks

# The test passes because the fragment shader always writes red; the loops do nothing.

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 GLF_live15c = vec4(0.0);
#   for (
#       int GLF_live15i = 0;
#       GLF_live15i < 4;
#       GLF_live15i++)
#   {
#     if (GLF_live15i >= 3)
#     {
#       break;
#     }
#     if (GLF_live15c[1] >= 1.0)
#     {
#       GLF_live15c[GLF_live15i] = 1.0;
#     }
#   }
#   vec4 GLF_live15d = vec4(0.0);
#   for (
#       int GLF_live15i = 0;
#       GLF_live15i < 4;
#       GLF_live15i++)
#   {
#     if (GLF_live15i >= 3)
#     {
#       break;
#     }
#     if (GLF_live15d[1] >= 1.0)
#     {
#       GLF_live15d[GLF_live15i] = 1.0;
#     }
#   }
#   _GLF_color = vec4(1.0, 0.0, 0.0, 1.0);
