  "message": "Improve variadic function call handling in PTA\n\nThe following fixes handling of __builtin_va_start handling and\nimplements .VA_ARG handling in PTA constraint generation to\nimprove precision around variadic calls.  I\u0027ve added a testcase\nfor IPA PTA involving an indirect variadic call verifying precision.\n\nThe pr99679-1.C no longer emits an expected error that was triggered\nby PTA calling aggregate_value_p on the .VA_ARG call which we no\nlonger do.\n\n\t* gimple-ssa-pta-constraints.cc (find_func_aliases_for_builtin_call):\n\tCorrectly use SCALAR rhs from the variadic argument part of\n\tthe function info or from NONLOCAL in case of intra-PTA.\n\t(find_func_aliases_for_call): Handle .VA_ARG.\n\n\t* gcc.dg/ipa/ipa-pta-20.c: New testcase.\n\t* g++.target/i386/pr99679-1.C: Remove expected error.\n\t* g++.target/i386/pr99679-2.C: Likewise.\n",
