+# Short description: Fragment shader with 1-iteration loop and smoothstep
+
+# The test passes because the loop exits immediately and red is written

+SHADER vertex variant_vertex_shader PASSTHROUGH

+# variant_fragment_shader is derived from the following GLSL:

+# precision highp int;

+# layout(location = 0) out vec4 _GLF_color;

+#  float g = 3.0;
+#  _GLF_color = vec4(smoothstep(0.0, 1.0, g), 0.0, 0.0, 1.0);
