<pre>A shader like
#define defined gl_Position
void main()
{
defined = vec4(1.0);
}
should either file to compile at line 1 or it should "just work." Instead,
Mesa produces a fairly obtuse error message:
0:5(2): error: `defined' undeclared
0:5(2): error: value of type vec4 cannot be assigned to variable of type
error
Apparently some dEQP test expects '#define defined' and '#undef defined' to
just work, but glslang generates an error. See also
<a href="https://github.com/KhronosGroup/glslang/issues/59">https://github.com/KhronosGroup/glslang/issues/59</a>. Either way, Mesa's behavior
is wrong.</pre>
