-  def ELPMRdZ : FLPMX<1, 0, (outs GPR8:$dst), (ins ZREG:$z),
+  def ELPMRdZ : FLPMX<1, 0, (outs LPM8:$dst), (ins ZREG:$z),
                       "elpm\t$dst, $z", []>,
----------------
I am not sure this is a good solution. Actually I can not write assmebly `LPM R30, Z`. Why no only use register calss `LPM8` / `DREGSLPM` only for pseudo instructions ?
