Description Gordon Jin 2010-01-11 23:48:20 UTC 
GLSL 1.10 spec section 5.3.2 says:
"It is an error to construct matrices from other matrices. This is reserved for future use."

But piglit/tests/glslparsertest/shaders/matrix.V110.frag (default #version 110) passes in mesa:

{
    mat4 m;
    mat4 m1 = mat4(m);
}

p.s. This is allowed in GLSL 1.20.
Comment 1 Eric Anholt 2010-08-17 08:41:50 UTC 
Fixed with the glsl2 merge.
Comment 2 Gordon Jin 2010-08-18 19:43:36 UTC 
verified with mesa master d442a01ac14382d83cdaac87d2832315ceb3e963.
