When the IL is rewritten after a statement has been processed and dependencies cached, its possible that an ssa-name in the dependency cache is no longer in the IL. Check this before trying to recompute. PR tree-optimization/109417 gcc/ * gimple-range-gori.cc (gori_compute::may_recompute_p): Check if dependency is in SSA_NAME_FREE_LIST. gcc/testsuite/ * gcc.dg/pr109417.c: New.
