Resolves: PR c++/86568 - -Wnonnull warnings should highlight the relevant argument not the closing parenthesis gcc/c-family/ChangeLog: PR c++/86568 * c-common.c (struct nonnull_arg_ctx): Add members. (check_function_nonnull): Use nonnull_arg_ctx as argument. Handle C++ member functions specially. Consider the this pointer implicitly nonnull. (check_nonnull_arg): Use location of argument when available. (check_function_arguments): Use nonnull_arg_ctx as argument. gcc/ChangeLog: PR c++/86568 * calls.c (maybe_warn_rdwr_sizes): Use location of argument if available. * tree-ssa-ccp.c (pass_post_ipa_warn::execute): Same. Adjust indentation. * tree.c (get_nonnull_args): Consider the this pointer implicitly nonnull. * var-tracking.c (deps_vec): New type. (var_loc_dep_vec): New function.
