Description Gordon Jin 2009-12-30 00:01:35 UTC 
GLSL spec (1.10 to 1.50) 6.1 says:
Function that return no value must be declared as void.

But this gets passed with mesa:
int function(out int i)  
{  // function should return a value
}

This impacts piglit/tests/glslparsertest/shaders/function5.frag
Comment 1 Gordon Jin 2010-06-29 23:32:33 UTC 
This also impacts piglit/tests/glslparsertest/glsl2/function-07.vert
Comment 2 Eric Anholt 2010-08-17 09:15:06 UTC 
Fixed with glsl2 merge.
Comment 3 Gordon Jin 2010-08-18 19:34:40 UTC 
verified with mesa master d442a01ac14382d83cdaac87d2832315ceb3e963.
