Fail link and validation of invalid tessellation program The GL_EXT_tessellation_shader spec says - The tessellation control and evaluation shaders are both optional. If neither shader type is present, the tessellation stage has no effect. However, if either a tessellation control or a tessellation evaluation shader is present, the other must also be present. Fail link and validation if a program contains TCS or TES shader but not both.
