/* The ARB_shading_language_420pack, GLSL ES 3.0, and GLSL 4.20
* specs add a clarification:
*
* "A void function can only use return without a return argument, even if
* the return argument has void type. Return statements only accept values:
*
* void func1() { }
* void func2() { return func1(); } // illegal return statement"
*
* Verify that returning void from a void function is illegal. Since it is a
* clarification rather than a spec change, this behavior is expected even
* without ARB_shading_language_420pack or before GLSL ES 3.0 or GLSL 4.20.
