David Malcolm c7a980b80b Prevent fix-it hints from affecting more than one line ... Attempts to apply a removal or replacement fix-it hint to a source range that covers multiple lines currently lead to nonsensical results from the printing code in diagnostic-show-locus.c. We were already filtering them out in edit-context.c (leading to -fdiagnostics-generate-patch not generating any output for the whole TU). Reject attempts to add such fix-it hints within rich_location, fixing the diagnostic-show-locus.c issue. gcc/ChangeLog: * diagnostic-show-locus.c (selftest::test_fixit_deletion_affecting_newline): New function. (selftest::diagnostic_show_locus_c_tests): Call it. libcpp/ChangeLog: * include/line-map.h (class rich_location): Document that attempts to delete or replace a range *affecting* multiple lines will fail. * line-map.c (rich_location::maybe_add_fixit): Implement this restriction.
