[Bug 42435] Suspected loss of varyings between shaders

https://bugs.freedesktop.org/show_bug.cgi?id=42435

--- Comment #7 from Alexander Sabourenkov screwdriver@lxnt.info 2011-11-01 17:53:45 PDT --- Further reducing shaders I got to this point:

#version 120 #line 2 0

varying float idx;

void main() { vec2 posn2 = posz*posn; idx = 0.625; gl_Position = gl_ModelViewProjectionMatrix*vec4(128, 128, 0.0, 1.0); gl_PointSize = 128; }

#version 120 #line 2 0 varying float idx;

void main() { gl_FragColor = vec4(idx, 0, 0, 1); }

This is in fact very close to glsl-novertexdata from the piglit.

Which still does not work on r600g and swrast while working ok on r600c and llvmpipe.
