Supports conversion of tabs to spaces when outputting diagnostics. Also adds -fdiagnostics-column-unit and -fdiagnostics-column-origin options to control how the column number is output, thereby resolving the two PRs. gcc/c-family/ChangeLog: PR other/86904 * c-indentation.c (should_warn_for_misleading_indentation): Get global tabstop from the new source. * c-opts.c (c_common_handle_option): Remove handling of -ftabstop, which is now a common option. * c.opt: Likewise. gcc/ChangeLog: PR preprocessor/49973 PR other/86904 * common.opt: Handle -ftabstop here instead of in c-family options.
