[LLVMdev] Custom Lowering and fneg

[Villmow, Micah]

Eli,
 Thanks for the help, I was able to fix my issue. When I was creating a
getCopyToReg I was assigning it as an i32.

Hmm, that's kind of strange... in that case, there's very little space
for it to get messed up.  Could you try setting a breakpoint in
"llvm::SelectionDAG::getNode(unsigned Opcode, MVT VT, SDValue
Operand)" and seeing where the fneg in question is built?
