--- Comment #7 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Author: jakub Date: Mon Jan 28 23:21:10 2019 New Revision: 268348 URL: https://gcc.gnu.org/viewcvs?rev=268348&root=gcc&view=rev Log: PR c/86125 * c-decl.c (last_fileptr_type): Remove. (last_structptr_types): New variable. (match_builtin_function_types): Compare TYPE_MAIN_VARIANT of {old,new}rettype instead of the types themselves. Assert last_structptr_types array has the same number of elements as builtin_structptr_types array. Use TYPE_MAIN_VARIANT for argument oldtype and newtype. Instead of handling just fileptr_type_node specially, handle all builtin_structptr_types pointer nodes. Formatting fix. * c-common.c (c_common_nodes_and_builtins): Build type variants for builtin_structptr_types types even for C. * gcc.dg/Wbuiltin-declaration-mismatch-7.c: Guard testcase for lp64, ilp32 and llp64 only. (fputs): Use unsigned long long instead of size_t for return type. (vfprintf, vfscanf): Accept arbitrary target specific type for va_list.
