The FE, normal and MD builtin numbers overlap, so one should always check what kind of builtin it is before looking at specific codes. On the other side, region-model.cc has: if (fndecl_built_in_p (callee_fndecl, BUILT_IN_NORMAL) && gimple_builtin_call_types_compatible_p (call, callee_fndecl)) switch (DECL_UNCHECKED_FUNCTION_CODE (callee_fndecl)) which IMO should use DECL_FUNCTION_CODE instead, it checked first it is a normal builtin... 2021-08-03 Jakub Jelinek <jakub@redhat.com> PR analyzer/101721 * sm-malloc.cc (known_allocator_p): Only check DECL_FUNCTION_CODE on BUILT_IN_NORMAL builtins. * gcc.dg/analyzer/pr101721.c: New test.
