  "message": "cgraph: Don\u0027t verify semantic_interposition flag for aliases [PR105399]\n\nThe following testcase ICEs, because the ctors during cc1plus all have\n!opt_for_fn (decl, flag_semantic_interposition) - they have NULL\nDECL_FUNCTION_SPECIFIC_OPTIMIZATION (decl) and optimization_default_node\nis for -Ofast and so has flag_semantic_interposition cleared.\nDuring free lang data, we set DECL_FUNCTION_SPECIFIC_OPTIMIZATION (decl)\nfor the ctor which has body (or for thunks), but don\u0027t touch it for\naliases.\nDuring lto1 optimization_default_node reflects the lto1 flags which\nare -O2 rather than -Ofast and so has flag_semantic_interposition\nset, for the ctor which has body that makes no difference, but as the\nalias doesn\u0027t still have DECL_FUNCTION_SPECIFIC_OPTIMIZATION (decl) set,\nwe now trigger this verification check.\n\nThe following patch just doesn\u0027t verify it for aliases during lto1.\nAnother possibility would be to set DECL_FUNCTION_SPECIFIC_OPTIMIZATION (decl)\nduring free lang data even for aliases.\n\n2022-04-28  Jakub Jelinek  \u003cjakub@redhat.com\u003e\n\n\tPR lto/105399\n\t* cgraph.cc (cgraph_node::verify_node): Don\u0027t verify\n\tsemantic_interposition flag against\n\topt_for_fn (decl, flag_semantic_interposition) for aliases in lto1.\n\n\t* g++.dg/lto/pr105399_0.C: New test.\n",
