The problem is that the caller uses its fndecl and fntype variables to fill up rdwr_map, and the fntype in that case is a prototype with the access attribute and all the checks needed for that performed. But the maybe_warn_rdwr_sizes function tries to rediscover fndecl/fntype itself and does it differently from how the caller did (for fndecl get_callee_fndecl and fntype from that FUNCTION_DECL, otherwise sets fntype to CALL_EXPR_FN's type). On the testcase, get_callee_fndecl does find a FUNCTION_DECL because it does STRIP_NOPS in between. Instead of trying to rediscover those, this patch just passes them down, like is done in several other functions. 2020-07-28 Jakub Jelinek <jakub@redhat.com> PR middle-end/96335 * calls.c (maybe_warn_rdwr_sizes): Add FNDECL and FNTYPE arguments, instead of trying to rediscover them in the body. (initialize_argument_information): Adjust caller. * gcc.dg/pr96335.c: New test.
