[LLVMdev] Why this fails on X86_64 host?

[Yabin Hu]

hi justn,

I have a llvm ir file which is generated by my own code generator.
When I run

*llc -march=ptx64 ./gpu_kernel.ll *

on it, the following error was given

LLVM ERROR: Cannot select: 0x269a7a0: ch = store 0x2666370, 0x2697760,

The ll file is attached here.
Please check this for me.
Thanks a lot!
