From: Ian Romanick <ian.d.roman...@intel.com>
glslangValidator rejects all of the shaders that try to change the
qualifier with errors like:
ERROR: 0:8: 'redeclaration' : cannot change qualification of gl_TexCoord
Mesa currently allows all of them to compile. Closed-source drivers
have not been tested.
glslangValidator rejects the shaders that try to change the type with:
ERROR: 0:8: 'gl_TexCoord' : redeclaration of array with a different element
type
Mesa currently rejects these with a somewhat less helpful error message.
Closed-source drivers have not been tested.
