Although it's not explicitly stated in the GLSL 1.50 spec, unsized
arrays are allowed in interface blocks.
section 1.2.3 (Changes from revision 5 of version 1.5) of the GLSL
1.50 spec says:
* Completed full update to grammar section. Tested spec examples
against it:
...
* add unsized arrays for block members
And section 7.1 (Vertex and Geometry Shader Special Variables)
includes an unsized array in the built-in gl_PerVertex interface
block:
out gl_PerVertex {
vec4 gl_Position;
float gl_PointSize;
float gl_ClipDistance[];
};
Furthermore, GLSL 4.30 contains an example of an unsized array
occurring inside an interface block. From section 4.3.9 (Interface
Blocks):
uniform Transform { // API uses "Transform[2]" to refer to instance 2
mat4 ModelViewMatrix;
mat4 ModelViewProjectionMatrix;
vec4 a[]; // array will get implicitly sized
float Deformation;
} transforms[4];
This patch adds the parser rule to support unsized arrays inside
interface blocks. Later patches in the series will add the
appropriate semantics to handle them.
Fixes piglit tests:
- spec/glsl-1.50/execution/unsized-in-unnamed-interface-block
- spec/glsl-1.50/linker/unsized-in-unnamed-interface-block
