Of course. Sorry -- I thought you would be able to reproduce locally.

The error is

I'm using llvm-3.1 from my distribution, which means the prefix is /usr.

If it's useful, I'm able to build working LLVMpipe using my automake patches.

To confirm, should I remove R600InstrInfo.td, R600IntrinsicsOpenCL.td,
and R600OpenCLIntrinsics.td from TD_FILES?
