Linking fails when not writing gl_Position

Graphics / Mesa 3D Graphics Library / Mesa - Kalyan Kondapally [intel.com] - 9 September 2014 02:39 UTC

According to GLSL-ES Spec(i.e. 1.0, 3.0), gl_Position value is undefined after the vertex processing stage if we don't write gl_Position. However, GLSL 1.10 Spec mentions that writing to gl_Position is mandatory. In case of GLSL-ES, it's not an error and atleast the linking should pass. Currently, Mesa throws an linker error in case we dont write to gl_position and Version is less then 140(GLSL) and 300(GLSL-ES). This patch changes it so that we don't report an error in case of GLSL-ES.
