  "message": "tree-optimization/120043 - bogus conditional store elimination\n\nThe following fixes conditional store elimination to properly\ncheck for conditional stores to readonly memory which we can\nobviously not store to unconditionally.  The tree_could_trap_p\npredicate used is only considering rvalues and the chosen\napproach mimics that of loop store motion.\n\n\tPR tree-optimization/120043\n\t* tree-ssa-phiopt.cc (cond_store_replacement): Check\n\twhether the store is to readonly memory.\n\n\t* gcc.dg/torture/pr120043.c: New testcase.\n\n(cherry picked from commit 93586e5d51188bf71f4f8fae4ee94ff631740f24)\n",
