Basically the partitioner somehow needs to be able to guarantee a maximum number of virtual operands per stmt. At the moment it tries to constrain the _average_ number of virtual operands per stmt, where the sanity check in tree-ssa-operands.c sets an upper bound to the number of virtual operands per stmt. These two do not match in degenerate cases, which triggers the ICE. -- rguenth at gcc dot gnu dot org changed: What |Removed |Added ---------------------------------------------------------------------------- Status|RESOLVED |REOPENED Resolution|FIXED | Summary|[4.3 Regression] ICE in |ICE in ssa_operand_alloc, at |ssa_operand_alloc, at tree- |tree-ssa-operands.c:484 |ssa-operands.c:484 | Target Milestone|4.3.0 |--- AssignedTo|rguenth at gcc dot gnu dot |dnovillo at gcc dot gnu dot |org |org Severity|blocker |normal Status|REOPENED |ASSIGNED http://gcc.gnu.org/bugzilla/show_bug.cgi?id=34093
