[LLVMdev] [PATCH] R600 - Fix zero extend of i1

[Jon Pry]

Hi,

    When trying to compile a trivial opencl kernel such as:

__kernel void if_eq(__global int * out, int arg0, int arg1){
    out[0] = arg0==arg1?0:1;
}

   Clang generates IR like:

  %1 = icmp eq i32 %arg0, %arg1
  %. = zext i1 %1 to i32

   This eventually crashes ISel on R600. Attached patch adds a selector so
it will compile.

Regards,

Jon Pry
