llvm dev - Mar 2013 - [LLVMdev] UNREACHABLE executed! error while trying to generate PTX

Well, I tried the command line given by you and I get the following error

clang++ nbody.kernel.cu -Xclang -fcuda-is-device
-I/home/upitamba/llvm-3.2.src/tools/clang/test/SemaCUDA/ -Xclang -triple
-Xclang nvptx64 -Xclang -target-cpu -Xclang sm_10 -S

fatal error: error in backend: Cannot select: 0x334a870: v4f32
NVPTXISD::MoveParam 0x334a770 [ORD=1] [ID=22]
  0x334a770: v4f32 = TargetExternalSymbol'.PARAM0' [ID=1]
In function: computeBodyAccel

Am I doing anything wrong here ?

Attached my new  nbody.kernel.cu
<http://llvm.1065342.n5.nabble.com/file/n56141/nbody.kernel.cu>  .cu here

That particular error is fixed in trunk, but with your code I'm now hitting
a new issue.  I'll get the fix in soon.

This file should compile fine now on trunk.
