Comment at: llvm/lib/Target/PowerPC/PPCISelDAGToDAG.cpp:4384
 
+static unsigned getTestSqrtOpcode(SDValue N) {
+  if (N.getOpcode() == PPCISD::FTSQRT) {
----------------
Do you have any problems to implement this folding with .td ? It doesn't make sense to me to get the opcode and then do the folding, as that is done during instr match(.td).
