GS:

#define INTERFACE_LOCATION(Pos) layout(location=Pos)
#define INTERFACE_BLOCK(Pos, Interp, Modifiers, Semantic, PreType, PostType)
layout(location=Pos) Interp Modifiers struct { PreType PostType; }
in gl_PerVertex
{
vec4 gl_Position;
float gl_ClipDistance[6];
} gl_in[];
out gl_PerVertex
{
vec4 gl_Position;
float gl_ClipDistance[6];
};
layout(triangles) in;
layout(triangle_strip, max_vertices = 3) out;
INTERFACE_BLOCK(0, noperspective , in , TEXCOORD0, vec2, Data) in_TEXCOORD0[3];
INTERFACE_BLOCK(1, , in , TEXCOORD1, uint, Data) in_TEXCOORD1[3];

VS:
#version 430
#extension GL_ARB_separate_shader_objects : enable
#define INTERFACE_LOCATION(Pos) layout(location=Pos)
#define INTERFACE_BLOCK(Pos, Interp, Modifiers, Semantic, PreType, PostType)
layout(location=Pos) Interp Modifiers struct { PreType PostType; }
out gl_PerVertex
{
vec4 gl_Position;
float gl_ClipDistance[6];
};
uniform ivec4 vu_i[1];
uniform vec4 vu_h[1];
INTERFACE_LOCATION(0) in vec2 in_ATTRIBUTE0;
INTERFACE_LOCATION(1) in vec2 in_ATTRIBUTE1;
INTERFACE_BLOCK(0, noperspective , out , TEXCOORD0, vec2, Data) out_TEXCOORD0;
INTERFACE_BLOCK(1, , out , TEXCOORD1, uint, Data) out_TEXCOORD1;

So it looks like they dropped the "semantic" which was giving the named types
and now just have anon types. Which I guess don't match up between programs for
some reason? Probably due to some array bs... that seems like an unrelated
issue though.</pre>
