--- Comment #3 from Jan Hubicka <hubicka at gcc dot gnu.org> ---
mine.

The summary is:
  loads:
      Base 0: alias set 1
        Ref 0: alias set 1
          access: Parm 0 param offset:4 offset:0 size:64 max_size:64
  stores:
      Base 0: alias set 1
        Ref 0: alias set 1
          access: Parm 0 param offset:0 offset:0 size:64 max_size:64

while with fwprop we get:
  loads:
      Base 0: alias set 1
        Ref 0: alias set 1
          access: Parm 0 param offset:0 offset:0 size:64 max_size:64
  stores:
      Base 0: alias set 1
        Ref 0: alias set 1
          access: Parm 0 param offset:0 offset:0 size:64 max_size:64

So it seems that offset is misaccounted.
