[Bug tree-optimization/27086] PRE looses SMT alias info

[rguenth at gcc dot gnu dot org]

------- Comment #1 from rguenth at gcc dot gnu dot org  2006-04-08 20:58 -------
SMT.18091 is only ever mentioned in RVUSE_IN/OUT, not for any value handle,
D.571521_46 also doesn't have a value handle.


Created value VH.4677 for fieldEngineBase_5
Created value VH.4679 for *VH.4677 vuses: (SMT.18080_30)
Created value VH.4710 for data_m
Created value VH.4711 for VH.4679.VH.4710 vuses: (SMT.18080_30)
Created value VH.4712 for blockControllerPtr_m
Created value VH.4713 for VH.4711.VH.4712 vuses: (SMT.18080_30)
Created value VH.4714 for ptr_m
Created value VH.4715 for VH.4713.VH.4714 vuses: (SMT.18080_30)

Created value VH.4716 for *VH.4715 vuses: (SMT.18083_148)
Created value VH.4717 for pBegin_m
Created value VH.4718 for VH.4716.VH.4717 vuses: (SMT.18083_148)

Found partial redundancy for expression VH.4716.VH.4717 (VH.4718)
NOTE: no flow-sensitive alias info for pretmp.18109_51 in pretmp.18111_48 =
pretmp.18109_51->pBegin_m;
NOTE: no flow-sensitive alias info for pretmp.18109_51 in pretmp.18111_48 =
pretmp.18109_51->pBegin_m;
Inserted pretmp.18111_48 = pretmp.18109_51->pBegin_m in predecessor 23


why's that SMT.18083 (if not 18091) not added to the stmt?
