diff of the relevant shader dump with and without the patch

commit 88c8f19 (r600/llvm: Store inputs in function arguments) causes some infinite loop compiling a shader in UH 3.0. Works fine with R600_LLVM=0 or by reverting the patch. I attached a shader dump diff with and without the patch. See also http://lists.freedesktop.org/archives/mesa-dev/2013-November/048433.html.

Can you post a dump with only the failing shader?
