Division by zero trying to compile the following simple vertex shader:

    uniform mat4 modelviewprojectionMatrix;

    attribute vec4 in_position;  
    attribute vec2 in_coord;     

    varying vec2 coord;          

    void main()                  
    {                            
        gl_Position = modelviewprojectionMatrix * in_position;
        coord = in_coord;        
    }

I don't know if you still do anything with Lima, but with a SDK release from a Chinese company happening today, I found some code of interest concerning Mali400-r4p0.

Drop me an email, I'll sent you the archive of source code that might worth your time.
