The inchash \"integer\" adds are a bit\nof a mess, but I know overloads with different integer types can get\nmessy, so not this time.  For hashing simply truncate to 64bits.\n\n\tPR tree-optimization/90242\n\t* tree-ssa-sccvn.cc (vn_reference_compute_hash): Use\n\tpoly_offset_int for offset accumulation.  For hashing\n\ttruncate to 64 bits and also hash 64 bits.\n\t(vn_reference_eq): Likewise.\n",
