-# Short description: A fragment shader that covers a specific instruction folding path.

-# The test passes because shader always writes red.

-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;
-# layout(set = 0, binding = 0) uniform buf0
-# {
-# int one;
-# };
-#
-# void main()
-# {
-# // division by zero results are undefined.
-# int tmp = one / 0;
-# if (tmp == 0)
-# _GLF_color = vec4(1, tmp, 0, 1);
-# else
-# _GLF_color = vec4(1, 0, 0, 1);
