--- Comment #1 from Sean Silva <silvas at purdue.edu> ---
It is included more than once:
- line 20 of NVPTX2.td
- line 2827 of NVPTXInstrInfo.td.

With r174582 we now diagnose double inclusion, which should avoid this issue in
the future:

sean:~/Downloads/tblgen % ~/pg/llvm/r+a/bin/llvm-tblgen -gen-tgt-intrinsic
NVPTX2.td
NVPTX2.td:20:9: error: File 'NVPTXIntrinsics.td' has already been included.
include "NVPTXIntrinsics.td"
        ^
Included from NVPTX2.td:19:
NVPTXInstrInfo.td:2827:9: note: previously included here
include "NVPTXIntrinsics.td"
        ^
NVPTX2.td:20:9: error: Unexpected input at top level
include "NVPTXIntrinsics.td"
        ^

btw, great bug report (including the attachment with everything needed inside).
