That's a proper place as the function is also called for optimize/target attributes (pragmas). However, it is possible that target overwrites an option from command line and so the diagnostics does not happen. That's fixed in the patch. - options are parsed and finish_options is called: if (opts->x_flag_unwind_tables && !targetm_common.unwind_tables_default && opts->x_flag_reorder_blocks_and_partition && (ui_except == UI_SJLJ || ui_except >= UI_TARGET)) { if (opts_set->x_flag_reorder_blocks_and_partition) inform (loc, "%<-freorder-blocks-and-partition%> does not support " "unwind info on this architecture"); opts->x_flag_reorder_blocks_and_partition = 0; opts->x_flag_reorder_blocks = 1; } It's not triggered because of opts->x_flag_unwind_tables is false by default, but the option is overwritten in target: ... if (TARGET_64BIT_P (opts->x_ix86_isa_flags)) { if (opts->x_optimize >= 1) SET_OPTION_IF_UNSET (opts, opts_set, flag_omit_frame_pointer, !USE_IX86_FRAME_POINTER); if (opts->x_flag_asynchronous_unwind_tables && TARGET_64BIT_MS_ABI) SET_OPTION_IF_UNSET (opts, opts_set, flag_unwind_tables, 1); ... PR driver/103465 gcc/ChangeLog: * opts.c (finish_options): More part of diagnostics to ... (diagnose_options): ... here. Call the function from both finish_options and process_options. * opts.h (diagnose_options): Declare. * toplev.c (process_options): Call diagnose_options.
