David Malcolm <dmalcolm at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |dmalcolm at gcc dot gnu.org --- Comment #1 from David Malcolm <dmalcolm at gcc dot gnu.org> --- Given that the driver takes the user-supplied command line and uses it to invoke cc1 etc, the command-line seen by cc1 doesn't bear a simple relationship to the one the user provided. So I don't know if there's a good way to implement this. Notes: c-opts.c:c_finish_options creates the <command-line> linemap by calling: 1381 cb_file_change (parse_in, 1382 linemap_check_ordinary (linemap_add (line_table, LC_RENAME, 0, 1383 _("<command-line>"), 0)));
