R600_DEBUG=vs output for failing shader

Trying to start the Elemental demo ends with this LLVM assertion failure:

Elemental: /home/daenzer/src/llvm-git/llvm/lib/CodeGen/VirtRegMap.cpp:369: void (anonymous namespace)::VirtRegRewriter::rewrite(): Assertion `PhysReg && "Invalid SubReg for physical register"' failed.
Comment 1 Michel Dänzer 2014-10-02 07:12:27 UTC 
Fixed with current LLVM SVN.
