------- Comment #5 from rguenth at gcc dot gnu dot org 2007-04-10 14:15 -------
There's one missed FRE opportunity in that we do not value-number
VIEW_CONVERT_EXPR<__v16qi>(D.6423) the same. This is because VIEW_CONVERT_EXPR
is tcc_reference I believe.
Created value VH.19 for VH.17.VH.18 vuses: (SFT.32_47)
Created value VH.20 for VIEW_CONVERT_EXPR<__v16qi>(VH.19)
Created value VH.21 for VIEW_CONVERT_EXPR<__v16qi>(VH.19)
Does the new VN fix that?
