| # A test for a bug reduced by GraphicsFuzz. |
| |
| # Short description: A fragment shader that uses a temporary struct variable |
| |
| # The test passes because the fragment shader is provided with a red vec4 |
| # as input, and copies this through to the output (via a struct) |
| |
| # The following GLSL, produced by SPIRV-Cross (and then manually edited for |
| # readability) shows what the shader does. |
| |
| # Fragment shader GLSL: |
| # #version 310 es |
| # precision mediump float; |
| # precision highp int; |
| # |
| # struct S |
| # { |
| # highp vec4 v; |
| # }; |
| # |
| # layout(binding = 0, std140) uniform somename |
| # { |
| # highp vec4 v; |
| # } buf; |
| # |
| # layout(location = 0) out highp vec4 color; |
| # |
| # S undef; |
| # |
| # void main() |
| # { |
| # S temp = undef; |
| # temp.v = buf.v; |
| # color = temp.v; |
| # } |
