--- Comment #2 from Ian Romanick <idr at freedesktop.org> ---
The problem is dst is marked as an "out" parameter of the function.  sampler
variables cannot be assigned, so it's impossible for it to be an out parameter.
 Deleting "out" allows the shader to compile.

Sadly, the compiler error message is useless for debugging that problem.
